PURPOSE: Venous compromise is the most common reason for perioperative free flap complications. The dependent nature of the lower extremity likely increases this risk, especially following significant lower extremity trauma with superficial or deep venous injury and immobilization of the soleal muscle venous pump. The benefit of a second venous anastomosis, however, remains unclear in lower ext...

PURPOSE To evaluate the safety of endovascular treatment of chronic cerebrovascular insufficiency (CCSVI) in patients with multiple sclerosis (MS). METHODS In a 1-year period, 461 MS patients (261 women; mean age 45.4 years, range 21-79) with CCSVI underwent endovascular treatment of 1012 venous lesions during 495 procedures [34 (6.9%) reinterventions]. While balloon angioplasty was preferred...

Endovascular retrieval of inferior vena cava (IVC) filters can be challenging due to prolonged dwell time and increased lateral tilt. Advanced endovascular techniques are needed in at least 15% retrievals associated with procedural complications. There is a need for dedicated devices improve efficiency patient outcomes. We demonstrate the technical aspects an advanced wire-loop technique IVC fi...

conclusions small dose of clopidogrel (75 mg) may lead to rare, life-threatening dah, so physicians should be aware of the possibility of dah after neurointervention in patients who have respiratory distress, worsening alveolar infiltrates accompanied by hemoptysis. introduction diffuse alveolar hemorrhage (dah) is a very rare complication but acute and life-threatening event. clopidogrel has g...

May Thurner Syndrome (MTS) is an anatomical variant in which the left common iliac vein is compressed against the fifth lumbar vertebra by the right common iliac artery resulting in lower extremity venous outflow obstruction. It is estimated to be present in about 20% of the population and predominantly seen in young females. It can present as acute or chronic DVT with symptoms of unilateral le...

OBJECTIVE To identify factors that predict a positive duplex scan examination result in patients with suspected deep vein thrombosis of the lower extremity. DESIGN Retrospective study. SETTING Vascular laboratory in a university teaching hospital. PATIENTS AND METHODS The results of 345 lower extremity duplex venous scans performed between August 1994 and November 1998 were reviewed. All ...

BACKGROUND The clinical pattern and long-term course of chronic inferior vena cava (IVC) obstructions are variable and depend on the underlying cause, the segment involved, and the extension of secondary thrombosis. Pertinent data on IVC obstructions in well-defined series of patients are lacking. We report the sequelae of chronic IVC obstructions in the hepatic segment in 11 consecutive patien...

OBJECTIVE The aim of this study was to determine whether endovascular or open revascularization provides an advantageous approach to symptomatic peripheral arterial disease (PAD) over the longer term. SUMMARY OF BACKGROUND DATA The optimal revascularization strategy for symptomatic lower extremity PAD is not established. METHODS We evaluated amputation-free survival, overall survival, and r...
