Abstract
Pulmonary embolism, Deep Vein Thrombosis (DVT) and Disseminated intravascular coagulation (DIC) are important sources of mortality and morbidity in intensive care unit (ICU). And every time D-dimer remains the the commonest investigation. Many times D-dimer is erroneously considered as a diagnostic test in above mentioned conditions. Its interpretation requires cautions. To circumvent this source of error it is necessary to understand D-dimer test and its significance in various disorder. This article review some basic details of D-dimer, condition associated with its increased level and some prognostic value in intracranial hemorrhage and gastrointestinal (GI) bleed.

Abstract
Pulmonary embolism (PE) is a deceptive condition which is often incorrectly diagnosed leading to high morbidity and mortality. We present a case where symptoms were localised to different areas of the body starting with post-traumatic pain over lower extremity varicosities that migrated sequentially over a month to the knee, hip, back, abdomen and chest finally presenting as syncope. Despite a low pre-test clinical probability, a very high index of suspicion led to a timely diagnosis of a massive bilateral PE that eventually caused a troponin leak. The aetiology is highly suspicious of a thrombus which originated in the veins of the leg due to trauma over varicose veins.The case described here exemplifies the importance of considering trauma to varicosities as a risk factor for embolism when the clinical picture is concerning but other signs and symptoms of PE are not apparent.

Abstract
Venous thromboembolism (VTE) is associated with substantial morbidity and mortality. Conventional treatment with anticoagulation therapy may undertreat the condition. Patients with VTE are at risk for recurrence with increasing time passage. Endovascular approaches exist for treating VTE, including deep vein thrombosis, but it is unclear which patients are appropriate candidates for endovascular versus medical approaches. Many new endovascular technologies are in development, and new oral anticoagulants are also on the market. Clinicians must be mindful of these new products and use them appropriately to better manage VTE.

Abstract
In this randomised controlled trial, we evaluated the role of elastic compression using ankle injury stockings (AIS) in the management of fractures of the ankle. A total of 90 patients with a mean age of 47 years (16 to 79) were treated within 72 hours of presentation with a fracture of the ankle, 31 of whom were treated operatively and 59 conservatively, were randomised to be treated either with compression by AIS plus an Aircast boot or Tubigrip plus an Aircast boot. Male to female ratio was 36:54. The primary outcome measure was the functional Olerud-Molander ankle score (OMAS). The secondary outcome measures were; the American Orthopaedic Foot and Ankle Society score (AOFAS); the Short Form (SF)-12v2 Quality of Life score; and the frequency of deep vein thrombosis (DVT). Compression using AIS reduced swelling of the ankle at all time points and improved the mean OMAS score at six months to 98 (95% confidence interval (CI) 96 to 99) compared with a mean of 67 (95% CI 62 to 73) for the Tubigrip group (p < 0.001). The mean AOFAS and SF-12v2 scores at six months were also significantly improved by compression. Of 86 patients with duplex imaging at four weeks, five (12%) of 43 in the AIS group and ten (23%) of 43 in the Tubigrip group developed a DVT (p = 0.26). Compression improved functional outcome and quality of life following fracture of the ankle. DVTs were frequent, but a larger study would be needed to confirm that compression with AISs reduces the incidence of DVT.

Abstract
Nephrotic syndrom is an association of proteinuria>3g/d or 50mg/kg/d, an hypoalbuminemia<30g/L and a hypoproteinemia<60g/L. Primary etiologies are minimal glomerular injury, focal segmental glomerulosclerosis and non membranous glomerulonephritis. Secondary etiologies are diabetes, high blood pressure and amyloidosis. We present four cases about nephrotic syndrome after thromboembolic disease. In every case, patients show a pulmonary embolism symptomatic of a nephrotic syndrom, whose diagnostic could be delayed up to six months after first pulmonary symptoms. This raised the problem of renal biopsy in these patients who need anticoagulation. In minimal change nephrosis, without hematuria, high blood pressure or renal dysfonction, a corticosteroid therapy test could be done assuming that is corticosensitive minimal glomerular injury. In every case, anticoagulation course must be completed and maintained in case of patent nephrotic syndrom with an albuminemia under 20g/L. In case of pulmonary embolism or deep vein thrombosis, idiopathic-looking, a nephrotic syndrome must be sought-after. The two diagnosis ways are the proteinuria on the urine dipstick and the hypoproteinemia on usual biology. The main mechanism is the coagulation factor leak, side effect of the nephrotic syndrom, notably because of the antithrombin III.

Abstract
INTRODUCTION Post-thrombotic syndrome (PTS) is a serious complication of deep vein thrombosis (DVT) of the leg that affects 20-50% of patients. Once a patient experiences PTS there is no treatment that effectively reduces the debilitating complaints. Two randomised controlled trials showed that elastic compression stocking (ECS) therapy after DVT for 24 months can reduce the incidence of PTS by 50%. However, it is unclear whether all patients benefit to the same extent from ECS therapy or what the optimal duration of therapy for individual patients should be. ECS therapy is costly, inconvenient, demanding and sometimes even debilitating. Tailoring therapy to individual needs could save substantial costs. The objective of the IDEAL DVT study, therefore, is to evaluate whether tailoring the duration of ECS therapy on signs and symptoms of the individual patient is a safe and effective method to prevent PTS, compared with standard ECS therapy. METHODS AND ANALYSIS A multicentre, single-blinded, allocation concealed, randomised, non-inferiority trial. A total of 864 consecutive patients with acute objectively documented proximal DVT of the leg are randomised to either standard duration of 24 months or tailored duration of ECS therapy following an initial therapeutic period of 6 months. Signs and symptoms of PTS are recorded at regular clinic visits. Furthermore, quality of life, costs, patient preferences and compliance are measured. The primary outcome is the proportion of patients with PTS at 24 months. ETHICS AND DISSEMINATION Based on current knowledge the standard application of ECS therapy is questioned. The IDEAL DVT study will address the central questions that remain unanswered: Which individual patients benefit from ECS therapy and what is the optimal individual treatment duration? Primary ethics approval was received from the Maastricht University Medical Centre. RESULTS Results of the study will be disseminated via peer-reviewed publications and presentations at scientific conferences. TRIAL REGISTRATION NUMBER NCT01429714 and NTR 2597.

Abstract
INTRODUCTION Deep vein thrombosis (DVT) has a strong inherited predisposition that is partly explained by the strong genetic risk factors such as mutations in factor V, prothrombin, antithrombin III, protein C and S genes. Only recently the first GWAS have been performed on DVT resulting in discovery of novel genetic variants, however, the information on the common polymorphisms predisposing to the risk of DVT is still scarce. MATERIALS AND METHODS Here we selected six SNPs (rs5361 in SELE, rs2066865 in FGG, rs2227589 in SERPINC1, rs1613662 in GP6, rs13146272 in CYP4V2, rs2289252 in F11) reported to be associated with venous thrombosis conditions and studied the association of these common variants in selected case (n=177) and control (n=235) groups from population of Latvia. Genotyping was performed using TaqMan hybridization probe SNP genotyping assay. RESULTS Patients with DVT had a significantly higher frequency of F11 rs2289252 polymorphism (p=0.001; OR [95%CI]=1.61 [1.20-2.14]). When stratified by recurrence of DVT the tendency was observed that the same SNP had higher OR value in group of DVT patients with repeated episodes of DVT compared to patients with single DVT episode (p=0.009; OR [95%CI]=2.27[1.22-4.21] and p=0.009; OR [95%CI]=1.52[1.11-2.08] respectively), but due to limited group of cases this finding should be replicated. CONCLUSION We conclude that F11 gene variant rs2289252 contribute to inherited forms of DVT incidence and correlation of other analysed SNPs should be explored in populations with greater sample size and associated with various thrombosis related traits.

Abstract
Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism, poses a substantial clinical risk, and the incidence of these thrombotic-related diseases remains high. Anticoagulation aims to prevent thrombus extension and reduce the risk of recurrent events, particularly fatal pulmonary embolism. In EINSTEIN DVT, rivaroxaban was non-inferior to enoxaparin/vitamin K antagonists for the reduction of recurrent VTE, with a similar safety profile and a net clinical benefit. EINSTEIN EXT investigated patients receiving long-term treatment in whom there was no clear decision about continuing or stopping anticoagulation; rivaroxaban was superior to placebo in the reduction of recurrent VTE, showing an acceptable benefit–risk balance. Rivaroxaban has the potential to replace standard therapy, usually parenteral low molecular weight heparin overlapping with and followed by a vitamin K antagonist, for the treatment of acute symptomatic DVT and the secondary prevention of VTE. As the use of rivaroxaban for DVT treatment increases in clinical practice, a fundamental understanding of its clinical benefits in everyday patient care is essential. XALIA (XArelto for Long-term and Initial Anticoagulation in venous thromboembolism) is a multicentre, prospective, non-interventional, observational study investigating the effectiveness and safety of a single-drug approach with rivaroxaban compared with standard therapy in patients with DVT. The study cohort will include approximately 4800 patients (≥18 years old) with objectively confirmed acute DVT who will be treated for a period of ≥3 months. The primary outcomes will be the incidence of treatment-emergent adverse events (primarily major bleeding), symptomatic recurrent venous thromboembolic events and all-cause mortality. Secondary outcomes include: major cardiovascular events; patient-reported treatment satisfaction and adherence; healthcare resource utilization; reasons for drug switching or interruption of treatment; and adverse events. XALIA will follow an international cohort of patients in more than 20 European countries, and others including Israel and Canada. The first patient was enrolled in June 2012, with results expected in 2015. It is anticipated that XALIA will provide important information on the treatment of DVT in a heterogeneous, unselected patient population in a real-world setting and provide important supplementary information to that obtained from the EINSTEIN DVT phase III study.

Abstract
BACKGROUND Few studies have assessed treatment patterns of acute venous thromboembolism (VTE) in a real-world population. We aimed to describe anticoagulant treatment patterns for acute VTE using healthcare databases of Québec, Canada. METHODS We used linked healthcare databases of the province of Québec, Canada to identify all incident cases of deep vein thrombosis (DVT) and pulmonary embolism (PE) between 2000 and 2009. We formed two patient cohorts, one with definite cases (definite VTE cohort, N=40,776) and the other including cases with definite or probable VTE (any VTE cohort, N=54,803) that were followed until death, end of health coverage, or end of study (December 31, 2009). RESULTS In the definite cohort, 73.6% of subjects were dispensed an anticoagulant following the diagnosis of VTE. Of those who were dispensed a vitamin K antagonist (VKA), median duration of use was 61days (interquartile range 89). VKA initiation was more likely in patients with pulmonary embolism than deep vein thrombosis alone (HR 1.62, 95% CI (1.58-1.66)). Among outpatients, those managed initially in the outpatient setting were less likely to initiate VKA therapy (HR 0.75, 95% CI (0.68-0.77)), while those requiring admission to hospital for VTE management were more likely to initiate (HR 1.81, 95% CI (1.76-1.87)). Findings were similar in the any VTE cohort. CONCLUSION Our study describes VTE treatment patterns in a real-world setting and suggests that there may be important gaps. These may include significant numbers of patients who did not initiate oral anticoagulant therapy, particularly in the outpatient setting, and shorter duration of oral anticoagulant use than recommended.

Abstract
Background Venous thromboembolic disease (VTE) is associated with high morbi-mortality. Adherence rate to the recommendations of antithrombotic prophylaxis guidelines (ATPG) is suboptimal. The aim of this study was to describe the adequacy of antithrombotic prophylaxis (ATP) in hospitalized patients as the initial stage of a program designed to improve physician adherence to –ATP recommendations in Argentina. Methods This study was a multicenter, cross-sectional study that included 28 Institutions throughout 5 provinces in Argentina. Results 1315 patients were included, 729 (55.4%) were hospitalized for medical (clinical) reasons, and 586 (44.6%) for surgical reasons. Adequate ATP was provided to 66.9% of the patients and was more frequent in surgical (71%) compared to clinical (63.6%) subjects (p < 0.001). Inadequate ATP resulted from underuse in 76.6% of the patients. Among clinical, 203 (16%) had increased bleeding risk and mechanical ATP was used infrequently. Conclusions The adequacy of ATP was better in low VTE risk clinical and surgical patients and high VTE risk in orthopedic patients. There was worse adequacy in high risk patients (with active neoplasm) and in those with pharmacological ATP contraindications, in which the use of mechanical methods was scarce. The adequacy of ATP was greater at institutions with < 150 beds compared with larger institutions. This is the first multicentric study reporting ATP in Argentina. Understanding local characteristics of medical performance within our territory is the first step in order to develop measures for improving ATP in our environment.

Abstract
This research project sought to design and implement a computerized clinical decision support system (CDSS) that was able to identify patients who were at risk of pulmonary embolism (PE) and deep vein thrombosis (DVT), as well as produce reminders for prophylactic action for these diseases. The main purpose of the CDSS was to attempt to reduce the morbidity and mortality caused by embolism and thrombosis in patients admitted to hospitals. After implementation of this system in one of the large educational hospitals of Iran, a standard questionnaire was used, and interviews were conducted with physicians and nurses to evaluate the performance of the designed system for reducing the incidence of pulmonary embolism and thrombosis. From physicians and nurses' point of view, a system which assists the medical staff in making better decisions regarding patient care, and also reminds pulmonary embolism and thrombosis preventive procedures with timely warnings, can influence patient care quality improvement and lead to the improved performance of the medical staff in preventing the incidence of pulmonary embolism and thrombosis.

Abstract
BACKGROUND While the incidence of venous thromboembolism increases with age, little is known about its contemporary management or outcomes in older patients. Our goal was to compare the characteristics, treatment, and outcomes associated with venous thromboembolism, in patients aged 65-69 years, 70-74 years, 75-79 years, and 80+ years. METHODS/PARTICIPANTS We prospectively followed 542 subjects aged ≥65 years with venous thromboembolism from January 2008 through August 2011 at 6 sites. In addition, a retrospective study of 681 additional subjects aged ≥65 years with venous thromboembolism diagnosed in 2007 and 2009 was conducted at the same 6 sites. RESULTS With advancing age, patients were more likely to suffer provoked venous thromboembolism but less likely to present with pulmonary embolism. Patients with unprovoked, provoked, or malignancy-associated venous thromboembolism received warfarin for a median of 401 days, 203 days, and 529 days, respectively. Age ≥80 years was not associated with an increased risk of recurrent venous thromboembolism, but there was an increased risk of all-cause mortality. CONCLUSION With advancing age, patients are more likely to suffer hospital-associated and provoked venous thromboembolism. Many elderly patients with provoked or unprovoked venous thromboembolism were treated for >3 months or >12 months, respectively. Given that advanced age was not associated with increased risk of recurrent venous thromboembolism, but elderly patients in general have a higher risk of bleeding from continued anticoagulant therapy, such practice is potentially harmful. At the same time, such an argument could be used to more vigorously offer prophylaxis in the first place.

Abstract
A 68-year-old woman who suffered from polycythemia vera presented at our clinic with the chief complaints of pain, swelling, and a warm sensation in her left thigh. She had undergone a left bipolar hemiarthroplasty following a hip fracture 24 days prior to this presentation. Her erythrocyte sedimentation rate and C-reactive protein (CRP) levels were elevated. In addition, a postoperative infection was suspected in the 3-phase bone scan; therefore, she received intravenous antibiotic therapy. This approach proved to be ineffective and she was subsequently diagnosed with a deep vein thrombosis via color Doppler ultrasonography. It is interesting to note that a deep vein thrombosis can present with symptoms similar to those of a postoperative infection. Furthermore, an elevated CRP level is frequently observed in patients suffering from polycythemia vera. Therefore, the two conditions, which require completely different treatments, can be confused. We report on this case with a review of the relevant literature.

Abstract
Up until today mobile outpatients are put into bed as soon as the diagnosis of deep vein thrombosis (DVT) is made. Fear of pulmonary embolism (PE) is the main rationale for bed-rest; additional arguments are pain and swelling which are expected to resolve faster during leg elevation. Based on previous work it is demonstrated that keeping mobile patients with acute DVT walking under exact anticoagulation does not increase the risk for symptomatic PE in comparison with bed-rest and that there is an immediate reduction of pain and swelling when good compression is applied and the patient is encouraged to walk. Immediate compression and walking seems also to reduce the incidence of a postthrombotic syndrome. One presumed mechanism of action of this adjunct treatment modality is the increase of shear stress in the microcirculation of the vein wall releasing anti-inflammatory and anti-coagulatory mediators.

Abstract
The post-thrombotic syndrome (PTS) as a long-term consequence of deep vein thrombosis (DVT) is caused by a venous obstruction and/or chronic insufficiency of the deep venous system. New endovascular therapies enable early recanalization of the deep veins aiming reduced incidence and severity of PTS. Extended CDT is associated with an increased risk of bleeding and stenting of residual venous obstruction is indispensable to avoid early rethrombosis. Therefore, this article focuses on measurements during or after thrombolysis indicating post procedural outcome.

Abstract
OBJECTIVE To determine the natural history of deep vein thrombosis in children presented with a first episode in the lower extremity veins. METHODS Children with objective diagnosis of acute deep vein thrombosis were followed up with ultrasound and clinical examination. Risk factors and clinical presentation were prospectively collected. The prevalence of recurrent deep vein thrombosis and the development of signs and symptoms of chronic venous disease were recorded. RESULTS There were 27 children, 15 males and 12 females, with acute deep vein thrombosis, with a mean age of 4 years, range 0.1-16 years. The median follow-up was 23 months, range 8-62 months. The location of thrombosis involved the iliac and common femoral vein in 18 patients and the femoral and popliteal veins in 9. Only one vein was affected in 7 children, two veins in 14 and more than two veins in 6. Recurrent deep vein thrombosis occurred in two patients, while no patient had a clinically significant pulmonary embolism. Signs and symptoms of chronic venous disease were present at last follow-up in 11 patients. There were nine patients with vein collaterals, but no patient developed varicose veins. Reflux was found in 18 veins of 11 patients. Failure of recanalization was seen in 7 patients and partial recanalization in 11. Iliofemoral thrombosis (p = 0.012) and failure to recanalize (p = 0.036) increased significantly the risk for developing signs and symptoms. CONCLUSIONS Children with acute proximal deep vein thrombosis develop mild chronic venous disease signs and symptoms at mid-term follow-up and are closely related with iliofemoral thrombosis and failure to recanalization.

Treatment of patients with acute deep vein thrombosis and/or pulmonary embolism: efficacy and safety of non-VKA oral anticoagulants in selected populations. Thromb Res 2014; 134:227-33. [PMID: 24875390 DOI: 10.1016/j.thromres.2014.05.013] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Revised: 05/02/2014] [Accepted: 05/07/2014] [Indexed: 12/12/2022]
Abstract
Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), presents a large clinical burden. Prompt, effective and sustained anticoagulation is vital because of the risk of recurrent events, including life-threatening PE, and complications such as post-thrombotic syndrome and chronic thromboembolic pulmonary hypertension. Dual-drug standard therapy is effective; however, parenteral low molecular weight heparin, coupled with routine coagulation monitoring and dose adjustment of vitamin K antagonists (VKAs), presents challenges for patients and healthcare providers. Non-VKA oral anticoagulants provide a simplified option for VTE treatment. Phase III studies have investigated rivaroxaban and apixaban as single-drug approaches, and edoxaban and dabigatran in conjunction with initial heparin therapy. These agents demonstrated non-inferiority to standard therapy, and most showed significant reductions in major bleeding. However, clinical information is limited in patient subgroups, e.g. fragile patients or patients with renal impairment or cancer, who may be at higher risk of bleeding and/or VTE. A prespecified pooled analysis of the EINSTEIN DVT and EINSTEIN PE studies (8281 patients), undertaken to evaluate clinical outcomes with rivaroxaban versus standard therapy, confirmed the non-inferiority of rivaroxaban, with significant reductions in major bleeding and fewer intracranial and retroperitoneal bleeding events. Consistent efficacy and safety were observed with rivaroxaban, irrespective of fragility, cancer or clot severity. The introduction of the non-VKA oral anticoagulants and approval of rivaroxaban in the EU, US and Canada for the treatment and secondary prevention of DVT and PE offer the potential for improvements in effective care across a broad spectrum of patients with VTE.

Abstract
PURPOSE Congestive heart failure (CHF) is one of the risk factors for deep vein thrombosis (DVT) according to the Japanese guidelines for DVT treatment and prevention. The purpose of this study is to estimate the frequency of DVT among hospitalized CHF patients, since there have been only limited DVT data in Japanese CHF patients. METHODS Patients enrolled in the study were with risk factors for DVT listed in the guidelines as well as with acute exacerbation of CHF, bed rest for at least 4 days, and aged 60 or above. Patients treated by physical prophylaxis or anti-platelet medication were included, while patients treated by any anticoagulant medicines were excluded. Patients with surgery or injury within 3 months before the hospitalization or diagnosed clinically or with obvious past history as having DVT at hospitalization were excluded. The presence of DVT in the eligible patients was determined by ultrasonography and the images were evaluated by an independent central evaluation committee. RESULTS Forty-four patients were enrolled in the study including 19 males and 25 females. The mean age was 79.0±10.6 years, and the mean duration of bed rest was 8.9±3.2 days. Out of these 44 patients, DVT was detected in 15 (34%) patients. Eight patients were on treatment with physical prophylaxis but DVT was still detected in two patients. Furthermore, 12 out of the rest of the patients were treated by anti-platelet agents and were still with DVT in 3 patients. CONCLUSION When evaluated ultrasonographically, the frequency of DVT in hospitalized non-surgical Japanese patients with CHF was approximately 35%. DVT occurred in 25% of patients treated by physical prophylaxis or anti-platelet agents. The results suggest that Japanese hospitalized patients with CHF have a high risk of DVT and thus can be recognized to have potential benefit by preventing and treating DVT according to the guidelines.

Abstract
A 66-year-old woman with a history of deep vein thrombosis (DVT) presented with an irregularly shaped leg ulcer surrounded by pigmentation on the left lower limb. In addition, the circumference of her left thigh had gradually increased. The ulcer did not respond to topical treatment and enlarged, therefore, she visited our hospital. Arteriography of the left lower limb showed multiple arteriovenous malformations (AVMs), based on which we made a diagnosis of a leg ulcer due to multiple AVMs. Transcatheter arterial embolisation with a mixture of N-butyl-2-cyanoacrylate and lipiodol was performed six times in the period of about a year for treating the AVMs. The ulcer was managed with bed rest, surgical debridement, continuous pressure support with elastic wrap and topical treatment. After 15 months, the ulcer healed, leaving pigmentation and scarring. It is quite rare for AVMs to progress in the elderly. We speculate that the DVT had caused occult AVMs to become symptomatic following an increase in size.

Abstract
JAK 2 mutation is the molecular event responsible for 95% of polycythemia cases and 50% of thrombocythemia vera and myelofibrosis cases. It can be used as a tool for the diagnosis of myeloproliferative disorders. We report a case illustrating the fact that a negative result does not definitively eliminate the diagnosis. A 40-year old woman, with a medical history of familial deep vein thrombosis, developed thrombosis of the inferior vena cava with extension to the suprahepatic veins and pulmonary embolism. No constitutional or acquired thrombophilia was diagnosed; search for JAK 2 mutation was negative. The patient was treated with fluindione. Five years later, she relapsed with popliteo-femoral and vena cava deep vein thrombosis. The etiological work-up included a PET scan which revealed diffuse uptake in bones and suspected neoplasic bone marrow invasion. Progenitor cell cultures were positive and JAK 2 mutation was confirmed. The bone marrow aspirate had the cytologic appearance of a myeloproliferative disorder. This case illustrates the fact that JAK 2 mutation can be identified several years after onset of a latent myeloproliferative disorder. Cases with a high clinical likelihood should lead to renewed search for this mutation. Secondary discovery of this mutation can be explained by a higher proportion of mutation expressing clones.

Abstract
Venous thromboembolism is a common postoperative complication, and orthopaedic procedures are particularly at risk. We designed a retrospective, single centre, observational, cohort study of 4127 patients (mean (SD) age 27 (11) years) who had elective orthognathic operations or distraction osteogenesis between January 1970 and February 2012 at the VU University Medical Centre, Amsterdam, to investigate the incidence in this group over the 42-year period, 2 patients developed symptomatic venous thromboembolism (1 woman had a deep vein thrombosis (DVT) and 1 man had a DVT and pulmonary embolus) postoperatively. In relatively young patients with low to moderate risk factors and short hospital stay this type of operation is associated with a particularly low risk of developing thrombosis. It could be advisable to limit the use of thromboprophylaxis to patients at high risk or according to hospital guidelines.

Abstract
OBJECTIVES Recent evidence suggests that there is an association between infection and venous thromboembolism (VTE). Here, we examined the risk of VTE after Staphylococcus aureus bacteraemia (SAB) compared to the risk in control subjects. DESIGN AND SETTING Register-based nationwide observational cohort study of hospitalized patients and matched control subjects from the general population in Denmark between 1995 and 2008. RESULTS Amongst 15 669 SAB cases and 156 690 controls, 182 and 511, respectively, experienced VTE within 1 year. The overall incidence rate (IR) of VTE amongst cases was highest within the first 30 days [IR of deep vein thrombosis (DVT), 39.3 (95% confidence interval (CI) 28.9-53.4)/1000 person-years (PYs); IR of pulmonary embolism (PE), 16.3 (95% CI 10.1-26.2)/1000 PYs]. IRs of DVT were particularly increased amongst cases with a previous diagnosis of VTE, community-acquired infection, a history of injection drug use and in younger age groups. The overall hazard ratio of VTE for cases compared to controls declined from 15.6 (95% CI 10.3-23.5) in the first 30 days after SAB to 4.5 (95% CI 3.2-6.2) from 181 to 365 days after infection. The increased risk of VTE amongst SAB patients persisted after excluding cases with identified VTE risk factors. CONCLUSIONS There was a particularly high risk of VTE during the first month following an episode of SAB. The risk declined over time, but remained at a threefold increased level compared to control subjects, suggesting that there are shared risk factors for SAB and VTE. Patients with SAB and well-documented risk factors for VTE may benefit from thromboprophylaxis.

Abstract
Upper extremity deep vein thrombosis (DVT) is a common finding after implantation of an automatic implantable cardiac defrillator (AICD). We describe the case of a patient who developed a left upper extremity DVT 4.5 months after implantation of an AICD and was found to have a lead-induced stenosis with possible underlying Paget-Schroetter syndrome (PSS) in the midbrachiocephalic vein on venography. While his symptoms resolved after the combination of pharmacomechanical thrombolysis, angioplasty, and anticoagulation, his long-term management is complicated by the presence of both PSS and lead-induced stenosis. Herein, we discuss his presentation, treatment, and future management options.

Abstract
OBJECTIVE To investigate the prevention of pulmonary embolism (PE) by the implantation of inferior vena cava filters (IVCFs). METHODS Data of 1058 patients treated for lower extremity deep vein thrombosis (DVT) between January 2005 and January 2012 were analyzed retrospectively and divided into those with and without PE. RESULTS Of the 1058 patients, 34 had PEs (3.2%) and 1024 did not. Multivariable analyses showed that PEs were less likely to occur in patients with IVCFs than in those without IVCFs (odd ratio [OR] = 0.028, P < 0.001), and were more likely to occur in patients with vena cava thrombosis than in those without vena cava thrombosis (OR = 19.094, P < 0.001). Analyses stratified by DVT site showed that vena cava thrombosis was the only risk factor of PE for patients with a left DVT (crude OR = 12.814, P < 0.001), and IVCF implantation was the only protective factor for PE for patients with a right or bilateral DVT (crude OR = 0.028, P = 0.001). IVCF patency rate for follow-up was 98.7% with no filter migration, declination, or failure of expansion. CONCLUSIONS IVCFs can reduce the occurrence of PEs in patients with DVTs.

Abstract
This article summarizes current information on the risk and the assessment of risks for deep venous thrombosis (DVT) resulting from plastic surgery procedures. Risk assessment is the foundation for recommended methods of prevention of DVT and, in turn, possible pulmonary emboli. If prevention fails, treatment of DVT is required to avoid the major complication of pulmonary emboli. The significant risk of DVT and pulmonary emboli after an abdominoplasty is confirmed in this article.

Abstract
OBJECTIVES Studies suggest that statins and low dose aspirin reduce risk of VTEs in the general population. We aimed to study the effect of these drugs on the incidence of VTEs in patients with ovarian cancer. METHODS Patients diagnosed with ovarian cancer between 2000 and 2011 were identified through the Clalit Health Services (CHS) chronic disease registry. Data were extracted from CHS database and from computerized pharmacy records. Use of medications was analyzed as a time dependent covariate in a Cox regression model. RESULTS Of 1746 patients 175 (10%) had a VTE during a median follow up of 3.13 years. 83 patients (5.6%) had a VTE within 2 years of diagnosis of ovarian cancer. Use of chemotherapy and stage 3 and 4 at presentation were associated with an increased risk for VTEs. Statins were used by 43.5% of the patients, and 32.3% used aspirin. Aspirin use was associated with a marginally significant reduction in incidence of VTEs within 2 years of diagnosis, HR 0.423 (95% CI 0.182-1.012, p-value 0.053). Statin use was not associated with risk of VTEs. CONCLUSION This is the first study looking at the effect of statins and aspirin on the incidence of VTEs in ovarian cancer patients. In our cohort, statins did not decrease the risk for a VTE and aspirin use was associated with a reduced risk which was marginally significant. Our results might be explained by use of low potency statins and by alternate mechanisms for VTE formation in cancer patients.

Abstract
Background Thromboprophylaxis for hospitalized patients with a high risk of venous thromboembolic events (VTEs) is strongly recommended but is not universally applied on medical units. Outside of randomized trials, there is minimal evidence that the usual medications reduce the incidence of clinically significant VTE. Methods We conducted a retrospective cohort study including all patients admitted into a teaching medical unit during years 2001-2002, 2003-2004, 2005-2006, 2007-2008 and 2009-2010. Inclusion criteria for the analysis were having one or more risk factors for a VTE and no contraindication to thromboprophylaxis. Results Of 2,369 patients reviewed, 1,302 satisfied the inclusion criteria. Between years 2001-2002 and 2009-2010, the proportion of patients receiving thromboprophylaxis increased from 29.2% to 76.4% (P < 0.0001) and the duration of thromboprophylaxis increased from 63% of hospital stay to 84% (P = 0.004). There was no statistically significant association between the number of risk factors and the rate of thromboprophylaxis. Overall, only 32 patients suffered from a VTE with no decrease in VTE incidence between years 2001-2002 and 2009-2010. A total of 107 patients had a bleeding event, and there was no statistically significant change in the incidence of bleeding during our study period. Conclusions In our medical units, we found a statistically significant increase in the use of the thromboprophylaxis practice. However, this was not associated with any statistically significant impact on the VTE incidence. This suggests that patients given thromboprophylaxis could be better selected.

Abstract
OBJECTIVE Venous thromboembolic disease is a common condition. Deep vein thrombosis (DVT) and pulmonary embolism are the most common manifestation but other locations may also occur. The objectives of the study were to estimate the incidence and determine the epidemiologic, topographic and associated conditions of venous thromboembolic disease in a department of internal medicine. METHODS A retrospective study of a series of 318 cases of DVT was conducted in Internal Medicine CHU Hedi Chaker, Sfax, during a period of 15 years (1996-2010). RESULTS DVT of the lower limbs was the most common location (87%). Other sites of DVT was noted in 16.35% of cases including upper limbs (19 cases), vena cava (16 cases), cerebral veins (10 cases), portal vein (10 cases) and hepatic vein (3 cases). A risk factor of VTE was found in 274 patients (86.1%). A state of thrombophilia was retained in 203 patients (63.5%). It was a hereditary thrombophilia (22.6%), an antiphospholipids syndrome (19.1%), Behçet's disease (16.4%) and neoplasia (7.2%). The study of the distribution of venous thrombosis as the seat and etiology showed that: the antiphospholipid syndrome was the most associated conditions with the upper extremity DVT (31.7%) whereas Behçet's disease was the most frequent etiology of vena cava thrombosis (7 cases) and the cerebral vein thrombosis especially in young males.

Abstract
BACKGROUND In trauma patients, Enoxaparin (a low molecular weight heparin, LMWH) prophylaxis for venous thromboembolism (VTE) risk reduction is unproven. METHODS Cohort analysis conducted consisting of all trauma patients age >13 admitted to Level-I trauma center and hospitalized >48 hours. VTE risk determined by the Risk Assessment Profile. High risk patients received LMWH unless contraindicated, while low and moderate risk patients received LMWH at attending surgeon's discretion. Odds ratio for VTE by logistic regression. VTE incidence, relative risk (RR), and number needed to treat (NNT) to prevent deep vein thrombosis (DVT) or pulmonary embolism determined by risk category. RESULTS Cohort consisted of 2,281 patients (1,211 low, 979 moderate, 91 high risks). VTE occured in 254 patients (11.1%). High-risk patients had significantly higher VTE incidence, odds ratio = 31.8 (P < .001). VTE was significantly reduced in high-risk patients receiving LMWH versus those who did not (.26 vs .53, P = .02). Among moderate and high risk, prophylactic LMWH reduced the incidence of pulmonary embolism (RR = .19, NNT = 40.4, P = .01), and trended toward reduced DVT incidence (RR = .81, NNT = 27.3, P = .15). LMWH lowered DVT incidence (RR = .52, NNT = 4.1, P = .03) in high risk patients. CONCLUSION Prophylactic LMWH is associated with reduction of VTE in trauma patients.

Abstract
BACKGROUND The neutrophil-lymphocyte ratio (NLR) has been identified as a potentially useful marker for predicting clinical outcome in patients with cardiovascular disease, diabetes, and various malignancies. The aim of this study was to determine whether NLR at the time of venous thromboembolism (VTE) diagnosis is a prognostic factor for the response to anticoagulation and survival in lung cancer patients treated with anticoagulation for VTE. PATIENTS AND METHODS We retrospectively analyzed the clinical characteristics, laboratory parameters, and NLR in 114 lung cancer patients newly diagnosed with VTE, among 991 patients pathologically confirmed for lung cancer between July 2008 and August 2013. RESULTS High NLR was significantly associated with high hematocrit (p=0.028), high C-reactive protein (p=0.002), and low albumin (p=0.001). Compared with the low NLR group, stage IV non-small cell lung cancer (NSCLC) at the time of VTE diagnosis (55.6 vs. 74.6%, p=0.055), central nervous system metastasis (5.8 vs. 25.8%, p=0.004), and cancer progression (14.3 vs. 38.8%, p=0.008) at the time of VTE diagnosis were also significant in the high NLR group. Moreover, the poor response to anticoagulation was statistically correlated with patients with NSCLC (p=0.037), high NLR (p=0.004), and low albumin (p=0.029). CONCLUSIONS The results demonstrate that the NLR at the time of VTE diagnosis could be a useful biomarker for predicting the response and prognosis following anticoagulation in patients with lung cancer and VTE.

OBJECTIVE Compression of the left common iliac vein between the right common iliac artery and the vertebrae is known to be associated with the occurrence of left iliofemoral deep vein thrombosis (DVT). In this study, we described the variability in vascular anatomy of the common iliac veins and evaluated the relationship between the degree of iliac vein compression and the presence of DVT using the data from surgeries for gynecologic cancer. METHODS The anatomical variations and the degrees of iliac vein compression were determined in 119 patients who underwent systematic para-aortic and pelvic lymphadenectomy during surgery for primary gynecologic cancer. Their medical records were reviewed with respect to patient-, disease-, and surgery-related data. RESULTS THE DEGREES OF COMMON ILIAC VEIN COMPRESSION WERE CLASSIFIED INTO THREE GRADES: grade A (n=28, 23.5%), with a calculated percentage of 0%-25% compression; grade B (n=47, 39.5%), with a calculated percentage of 26%-50% compression; and grade C (n=44, 37%), with a calculated percentage of more than 50% compression. Seven patients (5.9%) had common iliac veins with anomalous anatomies; three were divided into small caliber vessels, two with a flattened structure, and two had double inferior vena cavae. The presence of DVT was associated with the elevated D-dimer levels but not with the degree of iliac vein compression in this series. CONCLUSION Although severe compression of the common iliac veins was frequently observed, the degree of compression might not be associated with DVT in surgical patients with gynecologic cancer. Anomalous anatomies of common iliac veins should be considered during systematic para-aortic and pelvic lymphadenectomy in the gynecologic cancer patients.

Residual vein thrombosis and onset of post-thrombotic syndrome: influence of the 4G/5G polymorphism of plasminogen activator inhibitor-1 gene. Thromb Res 2014; 133:371-4. [PMID: 24485402 DOI: 10.1016/j.thromres.2013.12.032] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2013] [Revised: 12/08/2013] [Accepted: 12/28/2013] [Indexed: 11/30/2022]
Abstract
BACKGROUND Plasminogen activator inhibitor-1 (PAI-1) is the most important inhibitor of plasminogen activator. The functional 4G/5G polymorphism of the gene coding for PAI-1 may affect PAI-1 plasmatic activity, influencing the imbalance between coagulation and fibrinolysis cascades. In this prospective cohort analytic study, we investigated the role of this single nucleotide polymorphism in the persistence of thrombotic lesion and the occurrence of post-thrombotic syndrome. PATIENTS/METHODS In a group of 168 patients with post-surgical deep vein thrombosis of the legs, we analyzed the 4G/5G polymorphism in the promoter of PAI-1 gene and plasmatic PAI-1 activity. Enrolled patients were divided in two groups: patients with 4G/5G polymorphism and increased PAI-1 activity (n=85) and patients without 4G/5G polymorphism and normal PAI-1 activity (n=83). All patients were treated according to current protocols and re-examined after 3, 12 and 36 months in order to evaluate the persistence of thrombotic lesion and the occurrence of post-thrombotic syndrome. RESULTS We found a significantly increased PAI activity in carrier of the 4G allele, who experienced much more frequently a persistence of thrombosis after 3, 12 and 36 months and/or the development of post-thrombosis syndrome, in spite of the anticoagulant treatment. CONCLUSIONS These data not only confirm the role played by PAI-1 activity and by the 4G/5G SNP of the PAI-1 gene, but also suggest that current therapeutic protocols, recommending the administration of low weight molecular heparin and oral anticoagulant for the treatment of deep vein thrombosis, could be non sufficient for patients genetically predisposed to a less efficient clot lysis.

Abstract
BACKGROUND Behavior and substance addiction is one of the risk factors for deep vein thrombosis (DVT). The aim of this study investigating the relationship between the different clinical manifestations pattern of DVT with the way, the amount and duration of narcotic drugs in patients admitted to St. Alzahra Hospital in Isfahan, Iran, during 10 years. METHODS In a cross-sectional study we studied all of the patients with DVT in St. Alzahra Hospital since 2003-2013 were studied. FINDINGS A total of 238 (59.1%) of the patients were male and 165 (40.9%) female. The mean age of men and women were 18.80 ± 48 and 19.60 ± 3.48 years old. The mean length of staying in the hospital was 5.40 ± 7.20 days. Addiction among patients with DVT was 19.1%. 28.2% of men suffered from DVT and 6% of the women were drug addicts (P < 0.001). Among the 77 patients taking the drug, 53.2% were heroin, 35.1%opium, and 11.7% used other injectable drugs. The results showed that 19 patients (28.6%) were taking the drug once daily, 27.3% twice a day, 6.5% three times a day, 15.6% once a week, and 26% taking the drug twice a week. From 403 patients, 2.2% had a problem in the upper limb, 44.4% in the left hand, and 55.6 in the right hand. The results showed that none of the 77 studied patients had involvement of upper limbs, but all of them in the lower limb. About 11.2% of studied patients were addicted to injective drugs. Also, 6% were addicted to non-injectable drugs and 2% to both injectable and non-injectable drugs. CONCLUSION DVT has many risk factors and addiction and intravenously (IV) drug abuse one of the most important for this illness and this problem mast be noticed by health worker and physicians.

Abstract
BACKGROUND Brucellosis can involve almost any organ system and may present with a broad spectrum of clinical presentations. In this study, we present a case of deep vein thrombosis due to human brucellosis. CASE PRESENTATION A 15- year old boy presented with acute pain and swelling in his left thigh in June 2011, when he complained of fever, chills and lower extremity pain in which he could barely walk. In family history, his older brother had brucellosis 3 weeks ago and appropriate medication was given. The tubal standard agglutination test (wright test) and 2ME test were positive (in a titer of 1/1280 and 1/640, respectively). Peripheral venous doppler ultrasound of left lower extremity showed that common iliac, femoral, external iliac, superficial and deep femoral vein and popliteal vein were enlarged and contained with echogenous clot. He was treated with rifampicin 600 mg once a day, doxycycline 100 mg twice a day (both for three months) and amikacin 500 mg twice a day (for 2 weeks) accompanied with anti-coagulant. Ten days after the onset of this treatment, thrombophlebitis was cured. The follow up of the patient showed no abnormality after approximately one year later. CONCLUSION In brucellosis endemic areas, the clinicians who encounter patients with deep vein thrombosis and current history of a febrile illness, should consider the likelihood of brucellosis.

Abstract
BACKGROUND Eosinophilic gastroenteritis (EG) is rare and is characterized by recurrent eosinophilic infiltration of the gastrointestinal tract and chronic diarrhea. In this report we present a case of EG with acute pancreatitis and deep vein thrombosis (DVT). CASE PRESENTATION A 30 years old male was admitted to our hospital with the complaints of epigastric pain, vomitting and swelling of his left limb for the past six days. He was also having diarrhea for the last several months. He had been evaluated for chronic diarrhea and ascites before he sought the current consultation. Duplex color doppler of left limb showed DVT of distal calf vein. Contrast enhanced CT imaging of abdomen revealed thickening of duodenum, proximal jejunal wall and presence of ascites. Duodenal biopsy showed normal villous pattern with mild inflammation and eosinophilic infiltration. The constellation of clinical presentation, hypereosinophilia, CT and biopsy findings all is in consistence to EG. The patient was treated with prednisolone 20 mg/day for four weeks and tapered slowly. Acute pancreatitis was managed conservatively while DVT was treated with heparin and oral anticoagulants. The patient's diarrhea settled and ascites resolved completely. At follow up, the absolute eosinophil count was 300/μl and the patient was doing well. CONCLUSION This case report emphasizes that one should consider these rare disorders during the differential diagnosis of unexplained gastrointestinal symptoms in the presence of hypereosinophilia.

Abstract
Pediatric deep vein thrombosis is an increasingly recognized phenomenon, especially with advances in treatment and supportive care of critically ill children and with better diagnostic capabilities. High-quality evidence and uniform management guidelines for antithrombotic treatment, particularly thrombolytic therapy, remain limited. Optimal dosing, intensity and duration strategies for anticoagulation as well as thrombolytic regimens that maximize efficacy and safety need to be determined through well-designed clinical trials using use of a risk-stratified approach.

Abstract
OBJECTIVE To elucidate the current status of use of inferior vena cava filters (IVCFs) in cases of pulmonary embolism at institutions belonging to the Tokyo CCU Network. METHODS We conducted a retrospective investigation of 832 consecutive cases of pulmonary embolism reported on survey forms to the Tokyo CCU Network between 2005 and 2010. RESULTS Of 832 cases of pulmonary embolism, IVCFs were used in 338 (40.6%) and not used in 415 (49.9%). Their use was unclear in 79 (9.5%) cases. The use rate gradually increased each year from 2005 until 2008 but decreased from 2009 onward. Moreover, 68.9% of the IVCFs used in cases were non-permanent types. In terms of pulmonary embolism severity, the rate of use was 37.2% in non-massive cases, 49.4% in sub-massive cases, 46.9% in massive cases, and 31.9% in collapse cases. Thirty-day mortality in cases of collapse in which IVCFs were not used was extremely high at 75.8%, suggesting that in many cases, rapid deterioration may occur with insufficient time for IVCF insertion. The differences in IVCF usage rate among institutions were large in the range of 12.5-90% from 2005 to 2008, which slightly declined to the range of 25.0-72.2% from 2009 to 2010. CONCLUSIONS We elucidated the current IVCF use status in cases of pulmonary embolism at institutions belonging to the Tokyo CCU Network. Since the status of use differed among institutions, future studies of effective methods of use are required.

Abstract
OBJECTIVE To investigate Port-A-Cath (PAC)-related thrombosis and postthrombotic syndrome (PTS) in children with cancer. STUDY DESIGN The study population was a consecutive cohort of children diagnosed with cancer and a PAC implanted at diagnosis. Children were evaluated for the presence of PAC-related thrombosis by magnetic resonance venography and the presence of congenital prothrombotic risk factors and PTS. RESULTS A total of 114 children (median age, 6.04 years) were included. Of these children, 48 (42%) were treated for solid tumors and 66 (58%) were treated for hematopoietic tumors, including 38 for acute lymphoblastic leukemia. At the time of magnetic resonance venography, 42 children (37%) had the PAC still in place, and 72 (63%) had the PAC removed. Overall, PACs were in place for a total of 324.92 PAC-years. PAC-related thrombosis was detected in 45 children (39.5%) with a current or previous PAC. Of these, 21 (47%) had a solid tumor, 14 (31%) had acute lymphoblastic leukemia, and 10 (22%) had another hematopoietic tumor. Younger age at diagnosis, female sex, duration of PAC use, and left-side PAC placement were independently associated with an increased risk of thrombosis, whereas asparaginase therapy and the presence of inherited prothrombotic risk factors were not. Mild PTS (ie, presence of prominent collateral vessels in the skin) was present in 5.6% of the children. CONCLUSION PAC-related thrombosis is common in pediatric oncology patients. In some children, thrombotic complications can lead to the development of PTS.

Abstract
OBJECTIVE To evaluate the feasibility, safety, and effectiveness of single-session endovascular treatment with manual aspiration thrombectomy (MAT) as the first-line method of thrombus removal for iliac vein compression syndrome (IVCS) with secondary acute isolated iliofemoral deep vein thrombosis (DVT). METHODS This was a prospective clinical study. Twenty-six patients (19 women, 7 men, mean age 54 years) with left-sided acute iliac-common femoral DVT secondary to IVCS were enrolled. All patients presented with leg swelling or pains. Endovascular treatment, consisting of MAT, balloon angioplasty, and stent placement, was performed in the same setting. Overnight antegrade thrombolysis was performed in patients with residual thrombus after MAT. Patients were followed up by ultrasonography. The mean follow-up period was 17.8 months (12-25 months). RESULTS Single-session endovascular procedures were performed successfully in all patients. The mean procedure time was 67 minutes (ranging from 45 to 90 minutes). Complete thrombus removal, including almost 100% of removal in 24 patients and little residual thrombus (<5%) in two, was achieved after repeated MAT. Thrombolysis was used in these two patients. Complete symptomatic relief was achieved in 25 patients (96%) and partial relief in one. The hospital stay ranged from 2 to 4 days (mean 2.7 days). Recurrent thrombosis within the stent was observed in one case and recanalized with thrombolysis. The 1-year primary and secondary patency rate was 96% and 100%, respectively. No symptomatic pulmonary embolization, bleeding, and venous reflux were observed. Five patients complained about transitory low back pains during balloon angioplasty. CONCLUSION Single-session endovascular treatment with MAT as the first-line thrombus removal method is feasible, safe, and effective for IVCS with secondary acute isolated iliofemoral DVT. Although limited, our experience suggests that patients thought to be at high risk of bleeding may be candidates for the present single-session endovascular protocol.

Abstract
Deep vein thrombosis (DVT) is caused by obstruction of blood flow of deep veins in upper and lower limb. One of the precipitating factors for DVT is surgery under general anesthesia exceeding 30 min. However, there are very few reports of DVT associated with surgery of oral and maxillofacial region. In this paper we report two cases of DVT involving left ilio-femoropopliteal deep vein in one patient treated for fractured left angle of mandible and left peroneal vein in the other patient treated for oral sub mucous fibrosis. Clinical and color Doppler examination were performed to diagnose the condition and were referred to vascular surgical unit of higher institute for further management. These cases illustrates any surgery of maxillofacial region is not free from risk of DVT, which can cause fatal pulmonary thromboembolism.

Abstract
BACKGROUND The public health burden of venous thromboembolism, which includes deep vein thrombosis and pulmonary embolism, is not fully known, and contemporary incidence and mortality estimates are needed. We determined the incidence and case fatality of venous thromboembolism in a general population. METHODS Using the administrative health care databases of the Canadian province of Québec, we identified all incident cases of deep vein thrombosis or pulmonary embolism between 2000 and 2009 and classified them as definite or probable venous thromboembolism. We formed 2 patient cohorts, one with definite cases and the other including cases with definite or probable venous thromboembolism that were followed until December 31, 2009. RESULTS We identified 67,354 definite and 35,123 probable cases of venous thromboembolism. The age- and sex-adjusted incidence rates of definite or probable venous thromboembolism, deep vein thrombosis, and pulmonary embolism were 1.22 (95% confidence interval [CI], 1.22-1.23), 0.78 (95% CI, 0.77-0.79), and 0.45 (95% CI, 0.44-0.45) per 1000 person-years, respectively, while for definite venous thromboembolism it was 0.90 (95% CI, 0.89-0.90) per 1000 person-years. The 30-day and 1-year case-fatality rates after definite or probable venous thromboembolism were 10.6% (95% CI, 10.4-10.8) and 23.0% (95% CI, 22.8-23.3), respectively, and were slightly higher among definite cases. The 1-year survival rate was 0.47 (95% CI, 0.46-0.48) for cases with definite or probable venous thromboembolism and cancer, 0.93 (95% CI, 0.93-0.94) for cases with unprovoked venous thromboembolism, and 0.84 (95% CI, 0.83-0.84) for cases with venous thromboembolism secondary to a major risk factor. Similar survival rates were seen for cases with definite venous thromboembolism. CONCLUSION The risk of venous thromboembolism in the general population remains high, and mortality, especially in cancer patients with venous thromboembolism, is substantial.

Abstract
INTRODUCTION Phlegmasia caerulea dolens (PCD) is a clinical syndrome caused by venous obstruction leading to peripheral limb ischaemia. It can ultimately lead to venous gangrene, amputation or death in 25% of cases. PRESENTATION OF CASE A 52-year-old man with a background of myeloma developed PCD secondary to an obstructing plasmacytoma and left femoral vein deep vein thrombosis (DVT). These were treated with combined radiotherapy and anticoagulation, with resolution of the patient's symptoms. His recovery was complicated by the development of heparin-induced thrombocytopenia (HIT) and cutaneous vasculitis. DISCUSSION Both plasmacytoma and DVT are recognised complications of myeloma. This is, to our knowledge, the first description of these phenomena in combination causing PCD. The combination of venous stasis from the obstructing plasmacytoma and hypercoagulability from the underlying myeloma may have contributed to clot formation. A multifaceted treatment approach was required which aimed at improving venous flow via radiotherapy to the plasmacytoma and dissolving the obstructing clot with anticoagulant therapy. CONCLUSION PCD has a high mortality and morbidity. Recognition is important to avoid an incorrect diagnosis of arterial occlusion and inappropriate surgical intervention. Treatment must be focused on removing the offending causes.

Abstract
INTRODUCTION Studies suggest a decreasing risk of recurrent venous thromboembolism (rVTE) in relation to time since the index event. We sought to conduct a meta-analysis examining the time course of rVTE over the first 3-months of anticoagulation. MATERIALS AND METHODS A literature search of MEDLINE, EMBASE and CENTRAL (through 4/2013) was conducted to identify randomized trials of acute pharmacologic treatment and prevention of rVTE, enrolling ≥200 subjects/treatment arm, requiring anticoagulation for ≥3-months and reporting time-to-objectively-confirmed rVTE. Trials assessing extended-duration treatment, randomizing only cancer patients or not in English were excluded. Treatment arms were divided into monthly and weekly time periods for comparison (months 1-3 and weeks 1-12 after the index event). Treatment arm rVTE rates (per person-year) were pooled using a random-effects approach. RESULTS Fifteen trials (31 treatment arms; n=27,237) were included. Higher rVTE rates were observed during the first month after the index event (0.19, 95% CI=0.16-0.23) compared to the second (0.05, 95% CI 0.04-0.06; p<0.001 vs. first month) and third months (0.02, 95% CI=0.02-0.03; p<0.001 vs. first month). While the highest rate of rVTE was in week 1 (0.29, 95% CI=0.21-0.37; p<0.01 vs. week 2), rates remained high through the fourth week (between 0.15 and 0.10 events/person-year) before decreasing and stabilizing at week 5 (≤0.05 events/person-year; p<0.01 vs. week 4). CONCLUSIONS Our findings demonstrate a significant interaction between rVTE rates and time after the index event. High rVTE rates during the 3-4 weeks following the index event emphasize the importance of frequent surveillance during this time and the early optimization of pharmacologic therapy.

Abstract
BACKGROUND AND PURPOSE Accurate diagnosis of deep vein thrombosis in an outpatient setting is difficult; however, proper screening and prompt referral can be lifesaving. The purpose of this case report is to present the unusual findings of a Deep Vein Thrombosis (DVT) in an otherwise healthy young male following an upper extremity surgery. CASE DESCRIPTION An 18 year-old male high school baseball pitcher presented to the clinic for his four month follow up visit after Ulnar Collateral Ligament (UCL) reconstruction surgery. Patient complained of a recent "groin strain" and "calf strain" following baseball conditioning, that upon examination demonstrated signs and symptoms consistent with a deep vein thrombosis (DVT). OUTCOMES Following emergent referral the patient was diagnosed with multiple emboli and was treated with Lovenox and Coumadin. DISCUSSION Lower extremity DVT is a serious and potentially life threatening disorder. Physical therapists need to be vigilant in their subjective and objective examination of any patient that presents with lower extremity pain and swelling. This case report presents the unlikely findings of a DVT in a young, healthy, male high school baseball pitcher after surgical repair of the UCL. LEVEL OF EVIDENCE 4.

Surg Obes Relat Dis 2013; 10:469-73. [PMID: 24342034 DOI: 10.1016/j.soard.2013.07.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2013] [Revised: 07/04/2013] [Accepted: 07/15/2013] [Indexed: 11/28/2022]
Abstract
BACKGROUND Venous thromboembolism (VTE), which manifests as deep venous thrombosis (DVT) or pulmonary embolism (PE), is relatively uncommon after weight loss procedures but has the strong potential to affect patient morbidity and mortality. This type of complication has been studied extensively in more common weight loss procedures, such as Roux-en-Y gastric bypass (RYGB). VTE has not been studied after biliopancreatic diversion with duodenal switch (BPD-DS), a bariatric procedure performed mainly for super morbidly obese patients, who are inherently associated with a higher incidence of co-morbidity. The objective of this study was to review VTE prevalence and identify risk factors associated with the postoperative occurrence of VTE in a collected data set of patients after laparoscopic BPD-DS. METHODS The database of all patients who underwent laparoscopic BPD-DS between 2006 and 2012 was reviewed. Preoperative clinical information, which included history of VTE, inferior vena cava (IVC) filter placement, operative variables, and postoperative course, were reviewed. All VTE related events that occurred within 90 days postoperatively were collected and analyzed. RESULTS Of 362 patients who underwent laparoscopic BPD-DS during the study period, 12 (3.3%) experienced a VTE complication. Eight (2.2%) patients presented with DVT; 4 (1.1%) patients presented with PE. VTE complications were more common in females than males (83.3% versus 16.6%, respectively). Age, body mass index (BMI), and time interval between preoperative and postoperative doses of heparin for DVT prophylaxis did not influence the occurrence of VTE complications. However, operative time (P = .02) and length of hospital stay (P = .0005) were identified as risk factors associated with postoperative VTE complications. No related mortality occurred in this study. CONCLUSION The prevalence of VTE after BPD-DS is relatively low and comparable to other weight loss procedures. Overall risk of postoperative VTE after laparoscopic BPD-DS appears to be associated with the length of operation and hospital stay.

Pulmonary embolism and deep vein thrombosis related to oral contraceptive use. Obstet Gynecol Sci 2013; 56:273-6. [PMID: 24328015 PMCID: PMC3784135 DOI: 10.5468/ogs.2013.56.4.273] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2013] [Revised: 02/17/2013] [Accepted: 03/04/2013] [Indexed: 01/18/2023] Open
Abstract
Pulmonary embolism (PE) and deep vein thrombosis (DVT) is a serious medical problem causing considerable morbidity and mortality. Risk factors of thrombosis are surgery, trauma, pregnancy, tumor, oral contraceptive as well as genetic risk factors though genetic risk factors were found in about 5% to 10% of cases. Yasmin, a combined oral contraceptive containing ethinylestradiol 30 µg and drospirenon 3 mg was launched in the United Kingdom in 2002. We had experienced a patient, 24-year-old young woman with left inguinal pain on ambulation, and edema of left leg four months after taking Yasmin. We performed chest pulmonary angiography computed tomography (CT) and lower extremity venogram CT. She was diagnosed to PE in both lower lobes and DVT below the level of left external iliac vein, and treated by low molecular weight heparin and warfarin. We report this case with brief review of literatures.
