High-resolution CT angiogram (CTA) has replaced traditional diagnostic angiography as the main preoperative imaging modality for vascular surgery patients. Although the use of CTA is increasing for arterial imaging, it has not been used routinely for vein mapping. The goal of this study was to evaluate the accuracy of CTA for venous anatomy and compare it to a standard venous duplex ultrasound (DUS). When the vein was used for bypass, the quality and size of the vein were evaluated in the operating room. As part of a preoperative workup before lower extremity revascularization, 16 patients underwent a CTA followed by a DUS...

OBJECTIVES: To compare subcutaneous "Z"-stitch versus manual compression in attaining hemostasis after large bore femoral venous access, and to assess its impact on venous patency. BACKGROUND: Structural interventions increasingly require large caliber venous access, for which convenient, safe, and effective method of postprocedural hemostasis is needed. "Z"-stitch has been introduced for this purpose in some centers but systematic data on its performance is limited...

INTRODUCTION: The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis patients. Unfortunately, 20-40% of all constructed AVFs fail to mature (FTM), and are therefore not usable for hemodialysis. AVF maturation importantly depends on postoperative blood volume flow. Predicting patient-specific immediate postoperative flow could therefore support surgical planning. A computational model predicting blood volume flow is available, but the effect of blood flow predictions on the clinical endpoint of maturation (at least 500 mL/min blood volume flow, diameter of the venous cannulation segment ≥4 mm) remains undetermined...

PURPOSE: To determine predictors of recanalization in patients treated with endovenous cyanoacrylate. METHODS: Follow-up by serial clinical and duplex examinations was performed at 1 week, 1 month, 6 months, 12 months, and 24 months of 108 legs in 55 patients (21 men, median age 65 y) with primary varicose veins treated with endovenous cyanoacrylate. Cox regression analysis was used to examine venous characteristics before the procedure: diameter of great saphenous vein (GSV), treatment length of GSV, presence of incompetent perforators, clinical severity of varicose vein, and experience of operator as predictors of recanalization...

BACKGROUND: The immobilisation of the lower leg is associated with deep vein thrombosis (DVT). However, thromboprophylaxis in patients with a below-knee plaster cast remains controversial. We examined the efficacy and safety of nadroparin and fondaparinux to ascertain the need for thromboprophylaxis in these patients. METHODS: PROTECT was a randomised, controlled, single-blind, multicentre study that enrolled adults with an ankle or foot fracture who required immobilisation for a minimum of four weeks...

INTRODUCTION: The National Institute of Health defined 'erectile dysfunction' as the persistent inability to achieve and/or to maintain an erection for a satisfactory sexual performance. In last few years, the concept of erectile dysfunction has evolved from that of a disorder referred to as 'impotence' which used to be considered predominantly psychogenic to that of 'Erectile Dysfunction' (ED), a well understood physiologic result of multiple risk factors, both psychological and organic...

BACKGROUND: Venous thromboembolism (VTE) is a relatively common and potentially life threatening complication after major hip surgery. There are two main types of prophylaxis: chemical and mechanical. Chemical prophylaxis is very effective but causes bleeding complications in surgical wounds and remote organs. On the other hand, mechanical methods are free of hemorrhagic complications but are less effective. We hypothesized that mechanical prophylaxis is effective enough for Asians in whom VTE occurs less frequently...

Primary axillary venous aneurysms are rare, and there are only a handful of cases reported previously. The patient can be either asymptomatic or symptomatic, and can present with local axillary swelling, dilated venules in overlying skin associated with local discomfort, peripheral neuropathy, or pulmonary embolisms. A 30-year-old man presented with a four-month history of an uncomfortable lump in his left armpit that was associated with paraesthesia radiating down to his left forearm and hand. He had no history of arm swelling and had a normal motor neurological examination...

BACKGROUND: Good results have been reported for angioplasty and stenting of post-thrombotic lesions of the iliac and proximal femoral veins. If lesions at the origin of the superficial femoral and profunda veins are stented, the intraluminal synechiae can be pushed against the orifices of inflow vessels, potentially decreasing stent inflow. Surgical disobliteration of the common femoral vein (endophlebectomy) has been suggested to mitigate this problem. Because of a temporary increase in thrombogenicity, this procedure may be accompanied by arteriovenous fistula creation...

OBJECTIVE: Endovenous heat-induced thrombosis (EHIT) is a well-documented phenomenon that follows endovenous ablation, but the treatment, surveillance, and risk factors for EHIT have yet to be comprehensively elucidated. We sought to identify characteristics that may put patients at higher risk for development of EHIT after radiofrequency ablation (RFA) for the treatment of symptomatic superficial venous insufficiency. METHODS: A retrospective review was performed of all consecutive patients undergoing treatment with RFA to the great saphenous vein by a single surgeon from July 2013 through October 2015...

OBJECTIVE: Hybrid operative thrombectomy (HOT) is a novel technique for the treatment of acute iliofemoral deep venous thrombosis (IFDVT) and is an alternative to percutaneous techniques (PTs) that use thrombolytics. In this study, we compare perioperative and intermediate outcomes of HOT vs PT as interventions for early thrombus removal. METHODS: From July 2008 to May 2015, there were 71 consecutive patients who were treated with either PT (n = 31) or HOT (n = 40) for acute or subacute single-limb IFDVT...

BACKGROUND: Aspirin at 325 mg twice daily is now included as a nationally approved venous thromboembolism (VTE) prophylaxis protocol for low-risk total knee arthroplasty (TKA) patients. The purpose of this study is to examine whether there is a difference in deep vein thrombosis (DVT) occurrence after a limited tourniquet TKA using aspirin-based prophylaxis with or without extended use of mechanical compression device (MCD) therapy. METHODS: One hundred limited tourniquet TKA patients, whose DVT risk was managed with aspirin 325 mg twice daily for 3 weeks, were randomized to either using an MCD during hospitalization only or extended use at home up to 6 weeks postoperatively...

For a long time superficial thrombophlebitis has been thought to be a rather benign condition. Recently, when duplex ultrasound technique is used for the diagnosis more and more often, the disease is proved to be more dangerous than anticipated. Thrombosis propagates to the deep veins in 6-44% and pulmonary embolism was observed on the patients in 1,5-33%. We can calculate venous thromboembolic complications on every fourth patient. Diagnosis is clinical, but duplex ultrasound examination is mandatory, for estimation of the thrombus extent, for exclusion of the deep venous thrombosis and for follow up...

INTRODUCTION: Optimal enoxaparin dosing for deep venous thrombosis (DVT) prophylaxis remains elusive. Prior research demonstrated that trauma patients at increased risk for DVT based upon Greenfield's risk assessment profile (RAP) have DVT rates of 10.8% despite prophylaxis. The aim of this study was to determine if goal directed prophylactic enoxaparin dosing to achieve anti-Xa levels of 0.3-0.5IU/ml would decrease DVT rates without increased complications. MATERIALS AND METHODS: Retrospective review of trauma patients having received prophylactic enoxaparin and appropriately timed anti-Xa levels was performed...

Stasis dermatitis commonly occurs in older age. It is caused by venous hypertension resulting from retrograde flow due to incompetent venous valves, valve destruction, or obstruction of the venous system. Further tissue changes arise from an inflammatory process mediated by metalloproteinases, which are up-regulated by ferric ion from extravasated red blood cells. Stasis dermatitis presents initially as poorly demarcated erythematous plaques of the lower legs bilaterally, classically involving the medial malleolus...

PURPOSE: To report the use of adjunctive venography for the treatment of superficial venous reflux. METHODS: Two hundred consecutive patients (mean age 60.9 years, range 33-86; 128 women) with chronic venous disease underwent saphenous or perforator vein ablation in 268 limbs (305 venous trunks) guided by adjunctive venography and fluoroscopy in addition to ultrasound between October 2010 and May 2016. Intraprocedural venograms were independently evaluated by 2 vascular specialists to identify the presence of venous anomalies and the need for fluoroscopy-guided maneuvers to successfully complete venous ablation...
