BACKGROUND We wished to determine the nature and incidence of changes in the iliofemoral arteries after balloon dilation angioplasty (BDA) for aortic arch obstruction in children and to determine the reliability of gradient magnetic resonance imaging (MRI) in their detection. METHODS AND RESULTS Sixty-three children, including 62 with and 1 without arch obstruction, underwent MRI of the iliof...

Impedance plethysmography has great potential in the non-invasive detection of dangerous iliofemoral thrombosis. It was used to examine 198 patients undergoing total hip replacement for evidence of proximal venous segment thrombosis. There were 13 abnormal results, and subsequent venography in 12 of these revealed a false-positive rate of 4.0%; there was one false-negative result giving a sensi...

The medical and radiological records of 64 consecutive infants and children who underwent transfemoral balloon dilation of the aorta or aortic valve were reviewed to determine the incidence, nature, and post-treatment outcome of acute iliofemoral complications. Balloon dilation angioplasty or balloon valvotomy was performed with 8F and 9F catheters without an arterial sheath. Patients ranged in...

PURPOSE To evaluate the efficacy of catheter-directed low-dose recombinant tissue-type plasminogen activator infusion in the treatment of iliofemoral deep venous thrombosis and prevention of post-thrombotic syndrome. METHOD Eighteen patients (out of 260 evaluated) with acute iliofemoral deep venous thrombosis and no previous evidence of venous insufficiency were prospectively selected for thr...

Recent clinical studies have shed new light on the diagnosis of venous thromboembolism. Pulmonary embolism continues to be difficult to diagnose because the definitive test, pulmonary angiography, is complex and not widely available. However, new knowledge about ventilation perfusion lung scanning and non-invasive leg studies can help to reduce the need for pulmonary angiography. Furthermore, t...

A 57-year-old man with past medical history of asthma was transferred from an outside hospital for evaluation of cardiac mass where he was treated for extensive right lower extremity iliofemoral deep venous thrombosis with catheterdirected thrombolytic therapy and thrombectomy. Due to concern of compressive physiology at the site of thrombosis, 2 overlapping self-expanding WALLSTENT endoprosthe...

A case of iliofemoral deep vein thrombosis secondary to venous compression by a massively distended bladder is reported. Ascending venography was valuable in identifying the primary cause of venous obstruction, as well as guiding thrombolysis.

Background: The optimal therapy of acute iliofemoral venous thrombosis is still a matter of debate. The purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a Post Thrombotic Syndrome (PTS). Methods: During 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous thrombosis. 16...

PURPOSE To prospectively determine the distribution, extent, and age of venous thrombosis in patients presenting with acute signs and symptoms of venous thromboembolism and identify candidates for thrombolysis. MATERIALS AND METHODS Five hundred seventy-six consecutive patients (281 male, 295 female; mean age 58) referred for lower extremity deep vein thrombosis (DVT) assessment between Novem...

Iliofemoral acute deep venous thrombosis (DVT) poses increased risk for post-thrombotic syndrome. Absent inferior vena cava (IVC) syndrome is a rare vascular anomaly that can be associated with idiopathic DVT in the young patient. It remains unclear whether endovenous thrombolytic intervention for DVT in patients with absent IVC can be successful, given the impaired venous outflow. This case re...
