Abstract
Summary
Objective: To increase awareness on the severe impact of the nutcracker syndrome in women with undiagnosed disease. Patients and methods: We reviewed the medical literature and analyzed six representative series with 73 patients with nutcracker syndrome. Women with left flank pain, dyspareunia, dysuria, dysmenorrhea, micro- or macrohaematuria and pelvic congestion symptoms, should be carefully investigated for evidence of meso aortic left renal vein compression. A good number of our colleagues do not believe in the existence of the nutcracker syndrome and send these patients in a long pilgrimage in search of someone who can help them to get relief to their pain. New and improved imaging techniques can assist in the diagnosis but retrograde reno-gonadal phlebography and renocaval gradient are the most reliable diagnostic tools. Results: Among an assortment of treatment techniques, renal vein transposition and endovenous stenting were the two most commonly used procedures. There are no long term studies on renal vein stenting in children and young adults. Its use in these cases should be carefully considered. The nutcracker syndrome may present with pelvic congestion symptoms and its diagnosis missed. The patient's age, severity of symptoms and haemo dynamic renal studies should guide the treatment. Conclusion: An increased awareness of the existence of the nutcracker syndrome may prevent many unfortunate undiagnosed women from spending many months and often years of suffering.

Abstract
ZusammenfassungChronische Beckenschmerzen sind eine häufige Beobachtung bei mehrfachgebärenden Frauen im reproduktionsfähigen Alter. Seit Einführung neuer diagnostischer Methoden wurden Störungen der Beckenvenenzirkulation immer öfter als mögliche Ursache erkannt. Trotzdem sind die komplexen venösen Beckenvenensyndrome nicht ausreichend erforscht, Diagnose und Behandlung sind nicht standardisiert. Aufgrund unserer Erfahrungen mit 66 Patientinnen und einer umfangreichen Literaturrecherche geben wir eine Übersicht über Pathophysiologie, Diagnose und Behandlung von Beckenvenenzirkulationsstörungen.

Abstract
Primary lymphedema can be managed effectively as a form of chronic lymphedema by a sequenced and targeted treatment and management program based around a combination of Decongestive Lymphatic Therapy (DLT) with compression therapy, when the latter is desired as an adjunct to DLT. Treatment in the maintenance phase should include compression garments, self-management, including self-massage, meticulous personal hygiene and skin care, in addition to lymphtransport-promoting excercises and activities, and, if desired, pneumatic compression therapy applied in the home. When conservative treatment fails, or gives sub-optimal outcomes, the management of primary lymphedema can be improved, where appropriate, with the proper addition of surgical interventions, either reconstructive or ablative. These two surgical therapies can be more effective when fully integrated with manual lymphatic drainage (MLD)-based DLT postoperatively. Compliance with a long-term commitment to MLD/DLT and particularly compression postoperatively is a critical factor in determining the success of any new treatment strategy involving either reconstructive or palliative surgery. The future of management of primary lymphedema has never been brighter with the new prospect of gene-and perhaps stem-cell oriented management.

Abstract
OBJECTIVES To clear the confusion regarding the relationship between the 'primary lymphoedema' and (truncular) lymphatic malformation (LM); the latter is one of congenital vascular malformations. MATERIALS & METHODS A literature review was carried out on the primary lymphoedema either existing as an independent LM lesion or as a component of the Klippel-Trenaunay syndrome. RESULTS The review was able to provide a contemporary guide/conclusion on the definition and classification, clinical evaluation and clinical management regarding conservative (physical) therapy, reconstructive surgical therapy and ablative/excisional surgical therapy, for the primary lymphoedema as an LM. CONCLUSIONS Primary lymphoedema can be considered as 'congenital' since its majority represents a clinical manifestation of the truncular type of LM arising during the later stages of lymphangiogenesis. Such embryological staging information of the LM is critical for proper management of the primary lymphoedema when it exists with other congenital vascular malformations (Klippel-Trenaunay syndrome). 2. Basic non-invasive to minimally invasive tests will provide an adequate diagnosis and lead to the correct multidisciplinary, specifically targeted and sequenced treatment strategy. 3. The mainstay of current management of the primary lymphoedema/truncular LM is complex decongestive therapy; and the reconstructive as well as ablative surgical therapy remain adjunctive therapies at best.

Abstract
BACKGROUND Studies have reported that structural proteins such as elastin and collagen are decreased in varicose veins compared to normal controls. We hypothesized that the changes observed in varicose vein wall composition may be related to alterations in extracellular matrix remodeling proteins, such as the matrix metalloproteases and serine proteases. In addition we hypothesized that there may be regional variation in the expression of these enzymes within the leg. PATIENTS AND MATERIALS One-centimeter segments of the proximal and distal greater saphenous vein (GSV) were obtained from patients undergoing ligation and stripping for venous insufficiency (vv) (n = 15) or GSV harvest in conjunction with coronary artery bypass grafting (CABG) (n = 7). All vv patients had incompetence of the GSV by color flow duplex. Vein specimens were examined for MMP-1, 3, and 13, tryptase, and GAPDH mRNA using semiquantitative RT-PCR analysis. Quantification of MMP-1 and 13 (active/latent forms) and tryptase was performed using Western blot analysis. Western blots were analyzed using scanning densitometry and standardized to normal controls and values expressed as the median densitometric index (D.I.). Nonparametric statistical methods (Wilcoxan signed rank test and Mann-Whitney U test) were used for analysis. RESULTS We were able to amplify MMP-1, MMP-13, and tryptase mRNA from both proximal and distal segments of all greater saphenous veins studied. MMP-3 mRNA, however, was not found in either segment of any of the veins examined. A semiquantitative analysis of RT-PCR products comparing the ratio of MMP-1, MMP-13, or tryptase mRNA to GAPDH mRNA showed no difference between cases and controls nor proximal vs distal vein segments. Western blot analysis revealed larger quantities of MMP-1 in varicose veins than in nondiseased veins from CABG patients (48.0 +/- 36.7 D.I. vs 12.5 +/- 6.8 D.I., P = 0.036). Investigation into the regional variation of proteases revealed lower amounts of MMP-1 in distal than in proximal vein segments (37.9 +/- 35.0 D.I. vs 44.1 +/- 41.6 D.I., P = 0.01). Similarly, we found significantly less MMP-13 in distal segments of varicose veins than in proximal segments (152.8 +/- 130.0 D.I. vs 206.7 +/- 173.3 D.I., P = 0.006). CONCLUSIONS This study found that MMP-1 protein is increased in varicose veins when compared to controls despite no differences in mRNA expression. In addition we found that there is regional variation of MMP-1 and MMP-13 in diseased varicose veins. Lower leg veins have significantly reduced amounts of these proteolytic enzymes when compared to veins of the upper thigh. These data suggest that posttranscriptional regulatory controls could be responsible for the observed differences.

Abstract
Surgery under controlled ischemia has been extensively practiced by cardiac, plastic, orthopedic, vascular, and general surgeons. During the past 20 years, we have routinely used this technique to operate on a clean, bloodless field in complex cases of congenital vascular malformations. Based on our favorable experience, we have extended the use of the pneumatic tourniquet to complex cases of primary varicose veins. The use of the tourniquet has dramatically decreased the blood loss and operating time in complex venous surgery without complications secondary to its use. This technique represents a welcome alternative to the bloody, tedious, and time-consuming traditional varicose vein surgery of the past. Complex venous surgery for extensive varicose veins of the extremities can be safely and expeditiously performed under controlled ischemia. It should be the technique of choice.

Abstract
BACKGROUND Symptoms of pelvic venous congestion (chronic pelvic pain, dyspareunia, dysuria, and dysmenorrhea) have been attributed to massive gonadal reflux. However, obstruction of the gonadal outflow may produce similar symptoms. Mesoaortic compression of the left renal vein (nutcracker syndrome) produces both obstruction and reflux, resulting in symptoms of pelvic congestion. We describe the diagnosis and management of nine patients studied in our institutions. MATERIALS AND METHODS From a group of 51 female patients with pelvic congestion symptoms studied at our institutions, there were nine patients with symptoms of pelvic congestion, microscopic hematuria, and left-sided flank pain. The diagnosis of the nutcracker syndrome was suspected based on clinical examination, Doppler scan, duplex ultrasound scan, computed tomography scan, and magnetic resonance imaging. The diagnosis was confirmed by retrograde cine-video-angiography with renocaval gradient determination and catheterization of both internal iliac venous systems. All patients had a renocaval pressure gradient >4 mm Hg (normal, 0-1 mm Hg). Renal compression was relieved by external stent (ES) in two patients, internal stent (IS) in one patient, and gonadocaval bypass (GCB) in three. GCB was preceded by coil embolization of internal iliac vein tributaries connecting with lower-extremity varicose veins in three patients. Three patients deferred surgery and are under observation. Mean follow-up time was 36 months (range, 12-72 months). RESULTS Hematuria disappeared postoperatively in all patients. ES and IS normalized the renocaval gradient and resulted in significant alleviation of symptoms (90% improvement on a scale of 0-10 where 0 = no improvement and 10 = greatest improvement). Two patients with GCB had a residual gradient of 3 mm Hg. The third patient normalized the gradient. In this group, improvement of symptoms was 60%. Patients awaiting surgery are being treated conservatively (elastic stockings, hormones, and pelvic compression). They have shown only moderate improvement. CONCLUSION The nutcracker syndrome should be considered in women with symptoms of pelvic venous congestion and hematuria. The diagnosis is suspected by compression of the left renal vein on magnetic resonance imaging or computed tomography scan and confirmed by retrograde cine-video-angiography with determination of the renocaval gradient. Internal and external renal stenting as well as gonadocaval bypass are effective methods of treatment of the nutcracker syndrome. IS and ES were accompanied by better results than GCB. Surgical and radiologic interventional methods should be guided by the clinical, radiologic, and hemodynamic findings.

Abstract
Venous valves are delicate structures, the integrity of which is crucial for the normal function of the venous system. Their abnormalities lead to widespread disorders, ranging from chronic venous insufficiency to life-threatening thromboembolic phenomena. The discovery of the venous valves, however, has been the subject of hot controversy. Even though Fabricius ab Aquapendente is credited with the discovery by most historians, we demonstrate in this paper that other anatomists described them many years before Fabricius ab Aquapendente publicly demonstrated them in Padua in 1579. A thorough review of the historical literature surrounding the discovery of the venous valves was carried out from 1545 to the present under the supervision of the Medical History Department of our institution. Research was performed at the History of Medicine Division of the National Library of Medicine and through MEDLINE access to the medical literature. The Parisian Charles Estienne first mentioned the venous valves in his 1545 publication when he described "apophyses membranarum" in the veins of the liver. Lusitanus and Canano publicly demonstrated them in the azygos vein during cadaver dissections performed in Ferrera, Italy. The Parisian Jacques Sylvius described valves in the veins of the extremities in 1555. The work of these anatomists, however, could not achieve full recognition, because Andreas Vesalius, the leading anatomist at that time, was unable to confirm their findings and strongly denied the existence of venous valves. Vesalius's influence was so powerful that research on the subject was idle until 1579, when Fabricius ab Aquapendente "discovered" the venous valves. About the same time, the German Salomon Alberti published the first drawings of a venous valve (in 1585). William Harvey, a disciple of Fabricius ab Aquapendente, finally postulated the function of the venous valves, providing anatomical support for one of the greatest discoveries in medicine: the blood circulation. Therefore, our investigations revealed that Estienne and Canano discovered the venous valves in the 1530s. Fabricius ab Aquapendente's achievement was their full recognition 64 years later. However, it was not until 1628 that their function was fully understood, with the discovery of the blood circulation by William Harvey.

Abstract
PURPOSE The overall incidence of congenital vascular malformations in the general population is 1.5%. Approximately two thirds of them are malformations of venous predominance. Abnormalities of the deep venous trunks have been observed in association with large superficial compensatory varices in these type of malformations. Knowledge of the integrity of the deep venous system is important in their management because excision of the enlarged superficial veins may be deleterious if there is aplasia or hypoplasia of the deep venous trunks. The objective was to investigate the prevalence and nature of deep venous anomalies that occur in patients with congenital vascular malformations of venous predominance both in our series and in the series from the medical literature. METHODS From the last 35 years of medical literature, we reviewed seven series of congenital vascular malformations that provided pertinent information on the subject of our study. We also reviewed our own series of 392 patients with congenital vascular malformations studied at Children's Hospital of Mexico City (1963-1983; n = 223 children) and at Walter Reed Army and National Naval Medical Centers (1984-1998; n = 169 children). Of 392 patients, 257 (65.5%) had malformations of venous predominance; these were the subject of our analysis. Prevalence of the following deep venous anomalies was recorded: phlebectasia, aplasia or hypoplasia of venous trunks, aneurysms, and avalvulia. Diagnosis was made by one or more of the following methods: Doppler scanning, duplex scanning, plethysmography, computerized tomography, magnetic resonance imaging, and angiography. RESULTS At least one anomaly of the deep venous system was present in 47% of the congenital vascular malformations of venous predominance reviewed. Phlebectasia was recorded in 36% of the cases, and aplasia or hypoplasia of deep venous trunks was observed in 8% of the cases. Venous aneurysms also were present in 8% of the cases; avalvulia was recorded in 7% of the cases. CONCLUSION Anomalies of the deep venous system occur in almost one half of congenital vascular malformations of venous predominance. The most common is the relatively innocuous phlebectasias that occur in over one third of cases. Aplasia/hypoplasia, venous aneurysms, and avalvulia were less frequent, each less than 10%; but failure to detect the latter three anomalies may lead to serious therapeutic errors.

Abstract
PURPOSE Venous aneurysms have been reported to occur in most major veins. These aneurysms may be misdiagnosed as soft tissue masses or as inguinal or femoral hernias. Venous aneurysms of the deep system have been associated with deep venous thrombosis (DVT) and pulmonary embolism (PE). To more precisely characterize these lesions, we reviewed our experience with the disease. METHODS A retrospective analysis of our experience over 22 years was performed. The presentation and management of these lesions were reviewed and compared with the literature. RESULTS Thirty-nine venous aneurysms were reported in 30 patients. There were 14 men and 16 women. The patients' ages ranged from 3 to 75 years. Thirty aneurysms were located in the lower extremities, four in the upper extremity, and five in the internal jugular vein. Fifty-seven percent of lower extremity aneurysms occurred in the deep system. Patients' symptoms were a mass (75%) associated with pain (67%) and swelling (42%). Thromboembolism occurred in six patients, DVT in three, and PE in three. Eight of nine patients (89%) who had aneurysms of the superficial venous system had their condition misdiagnosed. Diagnosis was made by phlebography (60%), color flow duplex scanning (27%), continuous-wave Doppler scanning (10%), or magnetic resonance imaging (10%). The aneurysm size ranged from 1.7 to 6.0 cm. Management consisted of tangential excision in five (17%), total excision in 23 (77%), and observation in seven (6%). CONCLUSIONS Venous aneurysms are unusual vascular malformations that occur equally between the sexes and are seen at any age. Most patients have a painful mass of the extremity, and diagnosis is achieved by radiologic examination. Superficial venous aneurysms of the inguinal region are often misdiagnosed. Thromboembolism is more common in aneurysms involving the deep venous system. Because of their potential morbidity, management should be surgical in the majority of cases.

Abstract
Excision of varicose veins through ministab incisions is currently the choice for the removal of varicose vein clusters. The crochet hook technique of stab avulsion phlebectomy is described in this paper. This surgical method for the treatment of varicose veins has been widely utilized in a residency training environment during the last twelve years and has been used by the senior author for more than 20 years. The technique is easily mastered, cost effective, and has excellent therapeutic and cosmetic results.

Abstract
BACKGROUND Rapid diagnosis and typing of influenza virus are important for patient treatment and management during seasonal outbreaks. Centrifugation-enhanced rapid culture has been reported to be useful as an adjunct to traditional tube culture for rapid diagnosis of influenza virus. OBJECTIVES We compared rapid culture in 96-well plates against standard tube culture for recovery of influenza virus, types A and B. We also tested two different cell types, MDCK and RMK, to determine if the use of multiple cell lines increases the sensitivity of rapid culture. STUDY DESIGN The rapid method was initially evaluated by retrospective culture of previously positive frozen specimens. It was then compared to standard culture for recovery of influenza virus by parallel testing of fresh respiratory specimens. RESULTS Of 32 previously positive frozen specimens, 28 were positive upon repeat culture. Rapid culture recovered 25 (89.3%) and standard culture recovered 23 (82.1%). All positives were type A. Of 722 fresh specimens cultured in parallel, 76 (10.5%) were positive for influenza virus: 43 for type A and 33 for type B. For type A, rapid culture recovered 42 of 43 (97.7%) and tube culture recovered 39 (90.7%). For type B, rapid culture recovered 33 of 33 (100%) and tube culture recovered 24 (72.7%). In the rapid system, the MDCK cell line was positive for 40 of 42 type A positives (95.2%) and the RMK was positive for 41 (97.6%). The MDCK line was positive for 32 of the 33 type B isolates (97.0%) and the RMK cells were positive for all 33 (100%). CONCLUSIONS Rapid culture substantially reduced total test time and was more sensitive than tube culture. Duplicate cell lines did not significantly increase test sensitivity.

Abstract
Primary varicose veins of the upper extremity are extremely rare. We present three cases and discuss cause, diagnosis, and treatment. Three patients, a 23-year-old man, a 31-year-old woman, and a 39-year-old man, were referred with symptomatic varicose veins of the arm. None of the patients had lower extremity varicosities. Diagnosis was made by physical examination, noninvasive and invasive procedures, and excluded vascular malformations. Surgical treatment, similar to that for lower extremity varicose veins, entailed ligation and stripping of the varicose veins. Ligation and stripping were performed and successfully eliminated the varicosities with prevention of recurrence with a mean follow-up of 17 months. Although primary varicose veins of the upper extremity are extremely rare, they can be readily diagnosed and successfully treated, similar to lower extremity varicose veins. Although not proven, the cause is likely identical to lower extremity varicose veins. Excellent functional and cosmetic results can be obtained with surgical treatment.

Abstract
Maffucci's syndrome is a congenital nonfamilial syndrome combining dyschondroplasia, (enchondromatosis) and hemangiomatosis. It is a rare disease; only 200 cases have been reported throughout the world in the past 140 years. Over the past 20 years, four patients have been admitted with signs and symptoms consistent with Maffucci's syndrome. Three were children ages 3, 7, and 9 years. The fourth was 23 years old. Two were male and two female. All had hemangiomas at birth, and all had skeletal deformities and enchondromas. All complained of pain and heaviness of the involved extremity. Three patients had the arterial inflow evaluated with arteriograms, and one had magnetic resonance imaging. Two also had venograms. Two patients had excision of their hemangiomas, and one had sclerotherapy and compression therapy. All had bone biopsies performed. None of the enchondromas or the soft tissue lesions had undergone sarcomatous transformation.

Abstract
All surgical patients are at risk for the development of deep venous thrombosis and subsequent pulmonary embolism or postphlebitic syndrome. The evolution of ultrasonographic imaging has increased the awareness of prevention, diagnosis, and treatment of deep venous thrombosis. Duplex imaging and Doppler color flow imaging have made the diagnosis of deep venous thrombosis relatively simple, painless, inexpensive, and definitive. These procedures have gained acceptance by both patients and physicians. Several risk factors have been identified that increase the chance of the development of deep venous thrombosis. These factors include a history of deep venous thrombosis, presence of a malignant process, increasing age, cigarette smoking, obesity, prolonged bed rest, and general anesthesia. The greater the number of risk factors, the more aggressive prophylaxis should be. Means of prophylaxis have improved, and surgeons now generally agree that some form of prophylaxis is required. Heparin and intermittent compression devices appear to be equally effective in preventing deep venous thrombosis. The addition of venous monitoring in high-risk patients permits immediate identification of the presence of deep venous thrombosis. During the last decade, the treatment of patients with deep venous thrombosis has changed little. Heparin followed by warfarin remains the treatment of choice. A small group of patients receive fibrinolytic therapy for deep venous thrombosis. Although the incidence of postoperative deep venous thrombosis has decreased during the last decade, it remains a significant complication.

Abstract
Clinical and phlebographic evidence exists that correlates the presence of varices of the vulva, posterior thigh, and the pelvic congestion syndrome with insufficiency of the internal iliac venous system (pelvic dumping syndrome). Information in the modern medical literature regarding the valvular anatomy of the internal iliac veins and its tributaries is limited. We dissected 82 iliac venous system specimens in 42 human cadavers (29 men, 13 women) to gain information on the relationship between the disease described and the anatomy of the region. Each specimen contained common, external, and internal iliac veins, including the tributaries of the latter. We recorded the anatomic variations of the internal iliac vein trunk and the location of valves in the complete iliac venous system, including 485 tributaries of the internal iliac veins. Five specimens of internal iliac vein had calcified thrombosis or were extensively involved with pelvic carcinoma and were not suitable for valve study, which left 79 specimens for analysis. The internal iliac vein drained into the external iliac venous system by means of a single trunk in 73% of the specimens and by two well-formed and separated trunks in 27% of the specimens. In one specimen (1.2%) the internal iliac vein drained directly into the inferior vena cava (parallel internal and external iliac veins). One specimen had a well-developed valve in the common iliac vein (1.2%). The external iliac vein had one valve in 26.2% of the specimens. This vein had three times as many valves on the right side as in the left (39.6% vs 14.6%: p = 0.0106).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Chronic lower-leg edema in patients with venous disorders was studied by means of lymphoscintigraphy. Lymphatic patterns of flow were evaluated prospectively in 26 patients with technetium 99m antimony trisulfide colloid injected subcutaneously in the interdigital web spaces on the feet. Most patients in this study had postphlebitic syndrome, and all of these patients had abnormal lymphoscintigraphic flow patterns. Nine had evidence of lymphatic obstruction, and one had an enhanced flow pattern. Three patients had veins used for distal arterial bypass, and all these veins showed decreased lymphatic flow. Two patients with Klippel-Trenaunay syndrome (congenital varicose veins associated with limb elongation, a capillary nevus, and an abnormal deep venous system) had obstruction to lymphatic flow, and two others had normal and enhanced patterns. Normal studies were seen in four of five patients who had veins used for coronary artery bypass grafting. The finding of decreased lymphatic flow in patients appears to be the result of the length of time from an episode of deep venous thrombosis, the occurrence and number of episodes of cellulitis and lymphangitis, and mobilization of the vein for use in distal arterial bypass surgery. This study shows that the edema attributed previously to primary venous disorders may have a significant lymphatic component. The degree of lymphatic obstruction can be determined by lymphoscintigraphy with technetium-labeled antimony trisulfide colloid.
