Abstract
Takotsubo syndrome (TTS) is a cardiac syndrome characterized by transient left ventricular systolic dysfunction in the absence of significant obstructive coronary artery disease. At the autopsy, its diagnosis is often challenging, since it is generally thought that it relates to no characteristic macroscopic or microscopic findings. In order to verify this last statement, we performed a systematic review of the literature following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA) criteria. To the best of our knowledge, it is the first systematic review addressing this issue. We identified recurring but not pathognomonic (microscopic) features of TTS: contraction band necrosis and non-specific inflammatory changes (e.g., interstitial infiltrates of mononuclear lymphocytes and macrophages) typically in the absence of microscopic findings typical of acute myocardial infarction. In cases of TTS-related sudden death, careful evaluation of anamnesis, autopsy data and post-mortem genetic results (to exclude other causes) should be considered to overcome the complexity of these cases.

Abstract
The American Venous Forum (AVF) and the Society for Vascular Surgery set forth these guidelines for the management of endothermal heat-induced thrombosis (EHIT). The guidelines serve to compile the body of literature on EHIT and to put forth evidence-based recommendations. The guidelines are divided into the following categories: classification of EHIT, risk factors and prevention, and treatment of EHIT. One major feature is to standardize the reporting under one classification system. The Kabnick and Lawrence classification systems are now combined into the AVF EHIT classification system. The novel classification system affords standardization in reporting but also allows continued combined evaluation with the current body of literature. Recommendations codify the use of duplex ultrasound for the diagnosis of EHIT. Risk factor assessments and methods of prevention including mechanical prophylaxis, chemical prophylaxis, and ablation distance are discussed. Treatment guidelines are tailored to the AVF EHIT class (ie, I, II, III, IV). Reference is made to the use of surveillance, antiplatelet therapy, and anticoagulants as deemed indicated, and the recommendations incorporate the use of the novel direct oral anticoagulants. Last, EHIT management as it relates to the great and small saphenous veins is discussed.

Abstract
The sticky platelet syndrome is a congenital disorder, characterized by abnormal platelet aggregation in response to epinephrine and/or adenosine phosphate. We present a case of intraoperative carotid artery thrombosis, after patch angioplasty. The successful repair was only feasible on administration of antiplatelet therapy. Presence of sticky platelet syndrome should be considered during vascular operative interventions, and load of antiplatelet agents should be given in patients with unexplained repeated thrombosis of arterial repair, as we described and reported this case.

Abstract
This is a case report of a patient with Campylobacter fetus involving bilateral internal iliac artery aneurysms. The patient was treated successfully by ligation of the bilateral iliac artery aneurysms and antibiotics. According to a review of the English-language medical literature, this was the first such patient to be reported. A 69-year-old African-American male presented with a past medical history of repair of a 6.6 cm abdominal aortic aneurysm. It had been repaired with a Dacron bifurcated graft in July 2005. The bilateral internal iliac artery aneurysms (right 2.3 cm and left 3.4 cm) were coil embolized intraoperatively. The patient's past medical history was significant for hypertension and coronary artery disease and was status post-stent placement. He re-presented with fever and chills for 8 days in duration at home in March 2007. His fever was 101 to 102 degrees F. He denied vomiting, diarrhea, and a history of recent travel. The patient was admitted to the hospital for a fever workup. After an extensive workup, a left internal iliac artery aneurysm was found to be the source of sepsis. The patient was taken to the operating room for excision of the left internal iliac artery. No purulence was noted, but tissue overlying the aneurysm was thickened and fibrotic. Multiple cultures were taken. The tissue culture came back as C. fetus. Incidentally, the patient's preoperative computed tomographic scan revealed a right internal iliac artery aneurysm that was 4.2 cm on March 28, 2007, and 4.9 cm on April 23, 2007. Postoperatively, the patient's right internal iliac artery aneurysm was noted to be rapidly growing. He was promptly taken to the operating room for ligation of the right internal iliac artery aneurysm. The patient's postoperative course was unremarkable. He was discharged on ciprofloxacin for 14 days.

Abstract
Currently, the value of stenting during femoropopliteal balloon angioplasty (FPBA) remains unclear. Herein we evaluate the patency rates of successful duplex-guided balloon angioplasty (DAGBA) alone versus suboptimal DAGBA followed by stenting and the prestenting dissection versus recoil as potential indicators of stent success or failure. Over a period of 27 months, we performed 291 duplex-guided FPBAs (194 stenoses; 97 occlusions) on 244 limbs in 220 patients. Disabling claudication was the indication in 67%. Critical limb ischemia was the indication in the remaining 33%. Self-expanding nitinol stents were used when plaque dissection and/ or recoil caused diameter reduction > or = 40%. Serial follow-up duplex scans were obtained. Severe restenosis (> 70%) was measured by B-mode imaging and a peak systolic velocity ratio > 3. Follow-up ranged from 1 to 41 months (mean 10 +/- 8.3 months). The overall mean interval for restenosis and occlusion was 6.5 +/- 4.2 months and 5.6 +/- 6.1 months, respectively. Stents did affect overall patency results compared with not using stents. Reasons for stenting were plaque recoil, dissection, or both in 98 (53%), 44 (24%), and 42 (23%) cases, respectively. Six-month patency was 59%, 94%, and 69%, respectively. The difference between plaque recoil and dissection was significant (p<.04). The use of stents during FPBA may be associated with balloon angioplasty site failure in the femoropopliteal segment. To our knowledge, this is the first report ever to document plaque recoil as a predictor of balloon angioplasty site failure notwithstanding stent placement.

Abstract
We describe herein a combined approach to the treatment of popliteal artery aneurysms (PAA) that averts extensive dissections and potential blood loss particularly in cases of behind-the-knee aneurysms. Over the last 4 years, 13 patients (12 males) with mean age of 75 ± 8 years were treated for PAAs at our institution with a combined surgical and endovascular approach. The mean size of popliteal aneurysms was 2.9 cm ± 1.7 cm. One of the 13 cases (8%) was performed for acute ischemia and an additional 5 (38%) for claudication. All operations were performed under general anesthesia in supine position. Vein conduits (eight ipsilateral great saphenous veins, two contralateral great saphenous veins and one arm vein) were utilized for 11 bypasses. Of these, eight were from superficial femoral artery (SFA) to below the knee popliteal artery, two popliteal to popliteal and one SFA to posterior tibial artery. In addition, two expanded polytetrafluoroethylene femoral popliteal bypasses were performed. The distal anastomosis was performed after the popliteal artery was ligated distal to the aneurysm. Next, coil embolization of the aneurysmal sac was performed under fluoroscopic or ultrasound guidance. Coils were embolized through a 5F sheath. Lastly, the popliteal artery was ligated distal to the proximal anastomosis. Completion studies were obtained with duplex in six cases and arteriography in the remaining five cases. Mean follow-up was 11.6 months ± 9.6. One bypass occluded in 2 months after surgery. One patient demonstrated continued growth of his aneurysm despite coil embolization twice and underwent an open ligation of the branches perfusing the aneurysm from within the sac through a posterior approach. This approach may be particularly useful for PAAs located behind the knee where optimal surgical exposure is often difficult and the collateral circulation is abundant. The proposed technique is simple, effective and averts extensive dissections required to minimize blood loss.

Abstract
In an attempt to identify the fellows' concerns about the future of the field of vascular surgery, we conducted a survey consisting of 22 questions at an annual national meeting in March from 2004 to 2007. In order to obtain accurate data, all surveys were kept anonymous. The fellows were asked (1) what type of practice they anticipated they would be in, (2) what the new training paradigm for fellows should be, (3) to assess their expectation of the needed manpower with respect to the demand for vascular surgeons, (4) what were major threats to the future of vascular surgery, (5) whether they had heard of and were in favor of the American Board of Vascular Surgery (ABVS), (6) who should be able to obtain vascular privileges, and (7) about their interest in an association for vascular surgical trainees. Of 273 attendees, 219 (80%) completed the survey. Males made up 87% of those surveyed, and 60% were between the ages of 31 and 35 years. Second-year fellows made up 82% of those surveyed. Those expecting to join a private, academic, or mixed practice made up 35%, 28%, and 20% of the respondents, respectively, with 71% anticipating entering a 100% vascular practice. Forty percent felt that 5 years of general surgery with 2 years of vascular surgery should be the training paradigm, while 45% suggested 3 and 3 years, respectively. A majority, 79%, felt that future demand would exceed the available manpower, while 17% suggested that manpower would meet demand. The major challenges to the future of vascular surgery were felt to be competition from cardiology (82%) or radiology (30%) and lack of an independent board (29%). Seventeen percent were not aware of the ABVS, and only 2% were against it; 71% suggested that vascular privileges be restricted to board-certified vascular surgeons. Seventy-six percent were interested in forming an association for vascular trainees to address the issues of the future job market (67%), endovascular training during fellowship (56%), increasing focus on the vascular fellows at national meetings (49%), and representation for the fellows on the national councils (37%). This survey suggests that several significant issues exist in the minds of vascular trainees that have not been addressed and may present opportunities for further dialogue.

Abstract
Purpose. We hypothesized that adventitial transplantation of blood outgrowth endothelial cells (BOEC) to the vein-to-graft anastomosis of polytetrafluoroethylene grafts will reduce neointimal hyperplasia by reducing hypoxia inducible factor-1α (HIF-1α), by increasing angiogenesis in a porcine model of chronic renal insufficiency with haemodialysis polytetrafluoroethylene grafts. Because matrix metalloproteinases (MMPs) have been shown to be involved with angiogenesis, the expression of MMPs and their inhibitors was determined. Methods. Chronic renal insufficiency was created by subtotal renal infarction and 28 days later, arteriovenous PTFE grafts were placed bilaterally from the carotid artery to the jugular vein. Autologous blood outgrowth endothelial cells labeled with Lac Z were transplanted to the adventitia of the vein-to-graft anastomosis using polyglycolic acid scaffolding and scaffolding only to other side (control). Animals were killed 14 days later and vessels were explanted from the vein-to-graft anastomosis of both sides and underwent immunohistochemical analysis, western blotting and zymography for HIF-1α, MMP-2, MMP-9, TIMP-1 and TIMP-2. BOEC were also made hypoxic and normoxic for 12, 24 and 48 h to determine protein expression for MMPs and TIMPs. Results. Under hypoxia, BOEC significantly increased the expression of pro MMP-2 by 12 h and TIMP-2 by 24 h when compared to normoxic cells (P < 0.05). Transplantation of BOEC resulted in a significant decrease in both HIF-1α and intima-to-media ratio with a significant increase in both pro and active MMP-9 when compared to control vessels (P < 0.05). MMP-9 activity was localized to the neointima of the transplanted vessels by immunohistochemistry. There was increased CD31 density with engraftment of BOEC cells into the neointima of both the transplanted vessels compared to controls (P = NS). Conclusion. Transplantation of BOEC resulted in a significant decrease in intimal hyperplasia and HIF-1α with a significant increase in both pro and active MMP-9 that was localized to the neointima of transplanted vessels. The increase in MMP-9 offers a possible mechanism for angiogenesis and the reduced intima-to-media ratio. Furthermore, we observed that BOEC had homed to the neointima of the contralateral vessels that had increased levels of HIF-1α, suggesting that hypoxia may be an important stimulus for BOEC migration.

Abstract
Objective: Due to the inherent risks, deficiencies and cost associated with contrast arteriography (CA), our group has been utitilizing duplex arteriography (DA) for evaluating the arteries of the lower extremity for patients undergoing lower extremity revascularization. In an effort to further explore the strengths and weaknesses of DA, we reviewed our evolving experience with DA from January 1, 1998, to January 1, 2005. Patients and Methods: The arterial segments starting from mid-abdominal aorta to the pedal arteries were studied in cross-sectional and longitudinal planes using a variety of scanheads of 7–4, 10–5, 12–5, 5–2 and 3–2 MHz extended operative frequency range to obtain high-quality B-mode, color and power Doppler images as well as velocity spectra. In 906 patients, 1,020 duplex arteriograms were obtained. The ages ranged from 30–98 years old with a mean of 73±11 (SD) years. Fifty percent of the patients were diabetics. Indications for the examination included: tissue loss (409), rest pain (221), claudication (310), acute ischemia (74), popliteal aneurysm (45), SFA aneurysm (2), abdominal aortic aneurysms (AAA) (10) and failing bypass (55). Prior procedures had been performed in 262. DA was performed by six technologists (4 of whom are MDs). In all, 207 DA were performed intraoperatively and the remainder, preoperatively. Results: The resultant procedures based upon DA included: bypass to the popliteal artery (262) and bypass to an infrapopliteal artery (325), endovascular procedures (363), thrombectomy (11), embolectomy (9), inflow bypass procedures to the femoral arteries (46), débridment (4), amputation (8) and no intervention (75). The areas not visualized well included: iliac (73), femoral (26), popliteal (17), and infrapopliteal (221). Additional imaging after DA was deemed necessary in 102 cases to obtain enough information to plan lower extremity revascularization. Factors associated with increased need to obtain CA included: DM ( p<.001), infrapopliteal calcification ( p<.001), older age ( p = .01) and limb threatening ischemia ( p<.001). Factors not associated with the need to obtain CA included: which technologist performed the exam, whether the technologist has a medical degree and whether the patient underwent prior revascularization. Conclusions: In 90% of patients reviewed, DA is able to obtain the needed information to plan lower extremity revascularization. Severe tibial vessel calcification is the most common cause of an incomplete DA exam and determines when alternative imaging modalities need to be obtained.

Abstract
Congenital sliding, oesophageal or type I hiatal hernia was diagnosed in a five-month-old pug puppy presented for evaluation of dyspnoea post feeding. The diagnosis was confirmed using plain film radiography. Surgical reduction of the hernia followed by plication of the oesophageal hiatus, oesophagopexy and left flank gastropexy permitted restoration of normal function. At 12 months of age, the dog was asymptomatic. This article describes the diagnosis and treatment of a congenital type 1 oesophageal hiatal herniation with unusual clinical presentation.

Abstract
The role of routine use of duplex arteriography to diagnose thrombosis of popliteal artery aneurysm as a cause of acute lower extremity ischemia is investigated. In all, 109 patients (group 1) from 1994 to 1997 and 201 patients from 1998 to 2001(group 2) presenting with acute limb-threatening ischemia were studied. None of the group 1 patients underwent preoperative duplex arteriography, and no diagnosis of acute popliteal artery aneurysm thrombosis was made. Ten patients with acute ischemia due to thrombosed popliteal artery aneurysm were identified in group 2 when preoperative duplex arteriography was routinely performed. Urgent revascularization was performed based on the results of duplex arteriography. Six patients had functioning bypasses with a mean follow-up of 15.6 months. There were 3 deaths, 2 within 30 days and 1 after 2(1/2) years with functioning grafts. One patient was lost to follow-up. Routine use of duplex arteriography may provide the diagnosis and may identify the available outflow vessels for popliteal artery aneurysm.

Abstract
The objective of this study was to evaluate a percutaneous extravascular closure device (StarClose, Abbott Vascular, Redwood City, CA) after brachial endovascular approach. From 2004 to 2006, 29 patients received StarClose for brachial closure. Primary endpoints were successful deployment and absence of procedure-related morbidity, secondary endpoints were brachial artery patency on duplex and absence of late (> 30 days) complications. The device was successfully deployed in all patients. In two patients (6.8%) local complications occurred: one patient developed a large hematoma successfully treated with prolonged compression and a second patient presented with brachial artery occlusion requiring operative intervention. After a mean follow-up of 7.5±7.2 months, all patients had a palpable brachial/radial pulse; none had signs of infection, distal embolization or neurological deficits. On ultrasound b-mode imaging, the clip was visible as a 4 mm echolucent area at the outer anterior wall of the artery. Based on the peak systolic velocity ratios between the site of StarClose and proximal brachial artery (mean 1.08±0.2), none of the studied patients had a significant stenosis at the site of closure. StarClose is safe and effective in providing hemostasis following interventional procedures through the brachial artery; further advantages include patients comfort and early discharge.

Abstract
Venous injury and subsequent venous stenosis formation are responsible for hemodialysis graft failure. Our hypothesis is that these pathological changes are in part related to changes in wall shear stress (WSS) that results in the activation of matrix regulatory proteins causing subsequent venous stenosis formation. In the present study, we examined the serial changes in WSS, blood flow, and luminal vessel area that occur subsequent to the placement of a hemodialysis graft in a porcine model of chronic renal insufficiency. We then determined the corresponding histological, morphometric, and kinetic changes of several matrix regulatory proteins including VEGF-A, its receptors, matrix metalloproteinase (MMP)-2, MMP-9, tissue inhibitor of matrix metalloproteinase (TIMP)-1, and TIMP-2. WSS was estimated by obtaining blood flow and luminal vessel area by performing phase-contrast MRI with magnetic resonance angiography in 21 animals at 1 day after graft placement and prior to death on day 3 (n = 7), day 7 (n = 7), and day 14 (n = 7). At all time points, the mean WSS at the vein-to-graft anastomosis was significantly higher than that at the control vein (P < 0.05). WSS had a bimodal distribution with peaks on days 1 and 7 followed by a significant reduction in WSS by day 14 (P < 0.05 compared with day 7) and a decrease in luminal vessel area compared with control vessels. By day 3, there was a significant increase in VEGF-A and pro-MMP-9 followed by, on day 7, increased pro-MMP-2, active MMP-2, and VEGF receptor (VEGFR)-2 (P < 0.05) and, by day 14, increased VEGFR-1 and TIMP-1 (P < 0.05) at the vein-to-graft anastomosis compared with control vessels. Over time, the neointima thickened and was composed primarily of alpha-smooth muscle actin-positive cells with increased cellular proliferation. Our data suggest that hemodialysis graft placement leads to early increases in WSS, VEGF-A, and pro-MMP-9 followed by subsequent increases in pro-MMP-2, active MMP-2, VEGFR-1, VEGFR-2, and TIMP-1, which may contribute to the development of venous stenosis.

Abstract
A seven-year-old male Jack Russell terrier was presented with a history of coughing, generalised weakness and lethargy 10 days after an abdominal coeliotomy to repair a large diaphragmatic rupture. Thoracic radiographs demonstrated a soft tissue mass in the midcaudal right thoracic cavity. Ultrasonographic studies, bronchoscopy and subsequent exploratory thoracotomy confirmed a diagnosis of a right cranial lung lobe torsion (LLT), with an anomalous caudodorsal displacement of the affected lobe. LLT should be considered as a differential diagnosis for respiratory tract disease following diaphragmatic rupture repair.

Abstract
PURPOSE Current techniques to treat venous ulcerations and patients with severe lipodermatosclerosis include the elimination of incompetent perforator veins by open surgical ligation and division or by subfascial endoscopic perforator surgery. An alternative and less invasive means to obliterate perforator veins is ultrasound-guided sclerotherapy (UGS). We hypothesize that UGS is a clinically effective means of eliminating perforator veins and results in improvement of the clinical state (scores) without the complications associated with other more invasive methods. METHODS Between January 2000 and March 2004, UGS was used to treat chronic venous insufficiency in 80 limbs of 68 patients. This was a clinical series of patients who had perforator incompetence and no previous surgery for venous disease < or = 2 years of their UGS procedure. Most had perforator disease without coexisting axial reflux of the saphenous or deep venous systems. Color flow duplex scanning was used to identify incompetent perforator veins in the calf, and duplex guidance was used to inject each perforator with the liquid sclerosant sodium morrhuate (5%). Patients were restudied by duplex scanning up to 5 years after treatment. Clinical results were determined by Venous Clinical Severity Score (VCSS) and Venous Disability Score (VDS) before and after treatment. RESULTS Of the 80 limbs treated with UGS, 98% of incompetent perforators were successfully obliterated at the time of treatment, and 75% of limbs showed persistent occlusion of perforators and remained clinically improved with a mean follow-up of 20.1 months. According to the CEAP classification, there were 46.2% with limb ulceration or C6, 1.2% C5, 28.7% C4, 17.5% C3, and 6.2% C2 with pain isolated to the site of the perforator(s). Of those who returned for follow-up, the VCSSs changed from a median of 8 before treatment (95% confidence interval [CI], 3 to 15) to a median of 2 after treatment (95% CI, 0 to 7) (P < .01). Likewise, VDSs dropped from a median of 4 before treatment (95% CI, 1 to 3) to 1 after treatment (95% CI, 0 to 2) (P < .01). There were no cases of deep vein thrombosis involving the deep vein adjacent to the perforator injected. One patient had skin complications with skin necrosis. Perforator recurrence was found more frequently in those with ulcerations than those without. CONCLUSION UGS is an effective and durable method of eliminating incompetent perforator veins and results in significant reduction of symptoms and signs as determined by venous clinical scores. As an alternative to open interruption or subfascial endoscopic perforator surgery, UGS may lead to fewer skin and wound healing complications. Perforator recurrence occurs particularly in those with ulcerations, and therefore, surveillance duplex scanning after UGS and repeat injections may be needed.

Abstract
BACKGROUND Endovenous laser therapy (EVLT) and radiofrequency ablation (RFA) are new, minimally invasive percutaneous endovenous techniques for ablation of the incompetent great saphenous vein (GSV). We have performed both procedures at the Mayo Clinic during two different consecutive periods. At the time of this report, no single-institution report has compared RFA with EVLT in the management of saphenous reflux. To evaluate early results, we reviewed saphenous closure rates and complications of both procedures. METHODS Between June 1, 2001, and June 25, 2004, endovenous GSV ablation was performed on 130 limbs in 92 patients. RFA was the procedure of choice in 53 limbs over the first 24-month period of the study. This technique was subsequently replaced by EVLT, which was performed on the successive 77 limbs. The institutional review board approved the retrospective chart review of patients who underwent saphenous ablation. According to the CEAP classification, 124 limbs were C2-C4, and six were C5-C6. Concomitant procedures included avulsion phlebectomy in 126 limbs, subfascial endoscopic perforator surgery in 10, and small saphenous vein ablation in 4 (EVLT in 1, ligation in 1, stripping in 2). Routine postoperative duplex scanning was initiated at our institution only after recent publications reported thrombotic complications following RFA. This was obtained in 65 limbs (50%) (54/77 [70%] of the EVLT group and 11/53 [20.8%] of the RFA group) between 1 and 23 days (median, 7 days). RESULTS Occlusion of the GSV was confirmed in 93.9% of limbs studied (94.4% in the EVLT [51/54] and 90.9% in the RFA group [10/11]). The distance between the GSV thrombus and the common femoral vein (CFV) ranged from -20 mm (protrusion in the CFV) to +50 mm (median, 9.5 mm) and was similar between the two groups (median, 9.5 mm vs 10 mm). Thrombus protruded into the lumen of the CFV in three limbs (2.3%) after EVLT. All three patients were treated with anticoagulation. One received a temporary inferior vena cava filter because of a floating thrombus in the CFV. Duplex follow-up scans of these three patients performed at 12, 14, and 95 days, respectively, showed that the thrombus previously identified at duplex scan was no longer protruding into the CFV. No cases of pulmonary embolism occurred. The distance between GSV thrombus and the saphenofemoral junction after EVLT was shorter in older patients (P = .006, r(2) = 0.13). The overall complication rate was 15.4% (20.8% in the EVLT and 7.6% in the RFA group, P =.049) and included superficial thrombophlebitis in 4, excessive pain in 6 (3 in the RFA group), hematoma in 1, edema in 3 (1 in the RFA group), and cellulitis in 2. Except for two of the three patients with thrombus extension into the CFV, none of these adverse effects required hospitalization. CONCLUSION GSV occlusion was achieved in >90% of cases after both EVLT and RFA at 1 month. We observed three cases of thrombus protrusion into the CFV after EVLT and recommend early duplex scanning in all patients after endovenous saphenous ablations. DVT prophylaxis may be considered in patients >50 years old. Long-term follow-up and comparison with standard GSV stripping are required to confirm the durability of these endovenous procedures.

Abstract
Venous insufficiency in its severe forms leads to skin changes which, in turn may be treated by surgical therapy. Interventions are directed towards correction of the underlying abnormal venous physiology. This involves removal of varicose veins and ablation of incompetent axial veins and relevant perforating veins. In performing ablation of saphenous vein reflux, techniques include high ligation with stripping, radiofrequency ablation, endovenous laser therapy, and foam sclerotherapy. Incompetent perforator interruption can be accomplished surgically by subfascial endoscopic perforator surgery (SEPS) or controlled sclerotherapy using ultrasound. A variety of techniques have emerged to manage the varicose veins themselves. Surgical treatment of chronic venous insufficiency with high ligation in the groin and inversion stripping of the great saphenous vein to the knee combined with stab avulsion of varicose veins continues to be the standard in treatment of varicose veins. There are few comparisons of sclerotherapy of perforating veins with SEPS, but SEPS has become the most popular of surgical options.

Abstract
Carotid body tumors (CBT) are rare and usually benign neoplasms (60%-90%), originating from the mesoderm and neural ectoderm. In view of the extensive and unrelenting growth of unresected CBT, encasing vital neurovascular structures, and the significant incidence of malignancy (> or = 10%), surgical excision is the standard treatment of choice. Despite progress in CBT imaging and surgical technique, cranial nerve deficit, stroke, and death continue to affect 10% to 40% of patients undergoing curative surgical resection, particularly in large tumors proximal to the skull base. In such cases, CBT shrinkage by preoperative embolization, improved surgical access utilizing mandibular subluxation, and electroencephalographic monitoring combined with meticulous surgical technique may enable curative tumor resection, without prohibitive morbidity. In light of associated disability, preoperative acknowledgment of the ever-present substantial risk of cranial nerve injury cannot be overemphasized. We report on a patient with a large symptomatic CBT treated surgically with the aid of mandibular subluxation and preoperative embolization.

Abstract
OBJECTIVE Partial obstruction of postthrombotic veins is caused by endovenous scar tissue, which creates synechiae and septae that narrow and sometimes block the lumen. We have performed surgical disobliteration, or endophlebectomy, of chronically obstructed venous segments during various kinds of deep venous reconstructions to increase the flow through previously obstructed segments. In this article we describe the endophlebectomy technique, and report the availability of this procedure as an adjunct to deep venous reconstructions for the treatment of postthrombotic chronic venous insufficiency. Patients and methods Between July 1996 and February 2003, surgical disobstruction of 23 deep venous segments was performed in 13 patients in association with 14 deep venous reconstructions to treat advanced postthrombotic chronic venous insufficiency. Postthrombotic veins were surgically exposed, and a longitudinal venotomy was carried out at a variable length. The synechiae and masses attached to the intimal layer were carefully excised. Mean duplex scanning follow-up was 10.8 +/- 8.2 months (median, 8 months; range, 1-28 months). RESULTS In 10 patients (77%) the treated segments remained primarily patent at median follow-up of 8 months (range, 1-28 months). Early thrombosis near the endophlebectomy site occurred in 3 patients, at 2, 5, and 12 days, respectively, after surgery. In 2 patients with early thrombosis further interventions were carried out with success. In a third patient with early postoperative thrombosis the final outcome was recanalization and reflux. These results yielded an overall secondary patency rate of 93%. No perioperative pulmonary embolism was observed. CONCLUSION This series demonstrates that surgical disobliteration of postthrombotic deep veins is technically feasible, and led to patency of the segments for the duration of follow-up for up to 28 months (mean, 10.8 +/- 8.2 months). We used this technique with the objective of disobstructing postthrombotic veins, to increase flow through a previously narrowed lumen. Postoperative thrombosis at the site of endophlebectomy occurred in 23% of patients. Although this early experience is encouraging, further studies and longer follow-up are necessary to assess the durability of the procedure.

Abstract
BACKGROUND Few articles address the issue of LC in patients with cirrhosis. Existing articles are retrospective and with small sample sizes, which makes it difficult to draw conclusions about indications and complications with LC in this setting. STUDY DESIGN An extensive search of the Medline, Embase, and Cochrane databases using the terms "laparoscopic cholecystectomy" and "cirrhosis" or "cirrhotic" was conducted. The data from each study were extracted, combined with those of similar studies, and analyzed. RESULTS Twenty-five publications (400 patients with cirrhosis undergoing LC) from 1993 to 2001 were identified. Four articles compared LC with open cholecystectomy in patients with cirrhosis, and six compared patients with cirrhosis to patients without cirrhosis. Patients were primarily in Child-Pugh class A or B, with only six patients in Child-Pugh class C. Compared with patients without cirrhosis, patients with cirrhosis had higher conversion rates (7.06% versus 3.64%, p = 0.024), operative times (98.2 minutes versus 70 minutes, p = 0.005), bleeding complications (26.4% versus 3.1%, p < 0.001), and overall morbidity (20.86% versus 7.99%, p < 0.001). Acute cholecystitis was evident in 47% of patients with cirrhosis versus 14.7% of patients without cirrhosis (p < 0.001). When LC was compared with open cholecystectomy in patients with cirrhosis, LC was associated with less operative blood loss (113 mL versus 425.2 mL, p = 0.015), operative time (123.3 minutes versus 150.2 minutes, p < 0.042), and length of hospital stay (6 days versus 12.2 days, p < 0.001). CONCLUSIONS Patients with cirrhosis undergo cholecystectomies for more emergent reasons and have higher morbidity. The laparoscopic approach offers advantages of less blood loss, shorter operative time, and shorter length of hospitalization in patients with cirrhosis. Prospective studies will establish which factors affect outcomes and determine the appropriateness of LC in Child's-Pugh class C cirrhosis.

Abstract
BACKGROUND AND PURPOSE Deep venous reflux resolution after great saphenous vein surgery has been reported, but the studies evaluated mainly patients with deep segmental reflux. We prospectively analyzed the effects of greater saphenous vein ablation on coexisting primary deep axial venous reflux compared with segmental venous reflux. Patients and methods Between February 1997 and June 2001, patients with primary deep venous reflux scheduled for greater saphenous vein surgery were included in the study. Limbs of patients with a history of deep venous thrombosis, thrombophlebitis, trauma, and orthopedic or venous surgery were excluded. After surgery, duplex scanning was repeated and patients were examined for persistent deep venous reflux. RESULTS Thirty-three patients (38 limbs) were followed up with duplex scanning. Follow-up ranged from 2 weeks to 38 months. Preoperative axial deep reflux was present in 17 extremities, and segmental reflux was present in 21. The total number of incompetent segments was 59. Overall reflux abolishment rate was similar in extremities with axial and segmental reflux (30% vs 36%; P >.05). When segments were analyzed individually, abolishment of superficial femoral vein reflux was observed more often in extremities with segmental reflux than those with axial reflux (odds ratio, 4). In the extremities where deep reflux was not abolished with greater saphenous vein ablation, degree of reflux did not change significantly (P >.1). Duplex scanning was performed more than once during follow-up in 9 patients. In 3 of these patients reflux resolved by the second follow-up evaluation, and in 2 reflux was decreased at the second and third follow-up evaluations. CONCLUSION In patients with concomitant deep and superficial venous reflux, saphenous vein ablation results in resolution of deep reflux in about a third of patients. Superficial femoral vein reflux is seldom corrected in limbs with axial reflux compared with those limbs with segmental reflux. To appreciate the effects of greater saphenous vein ablation, longer follow-up may be needed.

Abstract
BACKGROUND A retrospective study was conducted to determine incidence and predisposing factors of incisional hernia after an emergency midline laparotomy. PATIENTS AND METHODS The study population consisted in 197 patients of whom 138 were followed-up for 2 years after surgery. RESULTS An incisional hernia developed in 25 (18.1%) patients at a mean follow-up of 11.2 months. Multivariate analysis showed the importance of age (> 60 years, p < 0.004), obesity (p < 0.008) and occurrence of post-operative wound infection (p < 0.00001) for the development of an incisional hernia. Univariate analysis showed that intestinal occlusion (p < 0.02), peritonitis (p < 0.006), upper abdominal access (p < 0.04) and post-operative wound infection (p < 0.003) in older patients and obesity (p < 0.003) and the presence of a neoplasm (p < 0.006) in younger patients, played a significant role. The comparison between young and old patients showed that upper abdominal access (p < 0.007), interrupted and layered wound closure (p < 0.02 and p < 0.01, respectively) and contamination of the operative field (p < 0.004) played a statistically significant role in older patients. CONCLUSIONS The rate of incisional hernia after an emergency midline laparotomy is higher than after elective procedures. However, it could be reduced with proper attention to the suture technique, i.e. mass and continuous suture, better preparation of the operative field and scrupulous sterility throughout the procedure in order to decrease the incidence of post-operative wound infection.

Abstract
Unsuspected microscopic adenocarcinoma (T1) of the gallbladder was identified after surgery in two patients who underwent urgent open cholecystectomy for acute cholecystitis. In spite of the tumor being at an early stage both patients died after few months for local and disseminated tumor recurrence. The influence of the associated inflammatory disease of the gallbladder on the outcome of patients with inapparent gallbladder carcinoma is discussed and a more aggressive surgical strategy is suggested.
