Purpose: To report the occurrence of acute postrenal kidney failure caused by external ureteral obstruction after iliac venous stent placement.
Case Report: A 73-year-old male patient presented with a chronic swelling and feeling of heaviness of his right leg. The presence of venous thrombosis was excluded by duplex ultrasound (DUS).
Background: Postinterventional sonographic assessment of the femoral artery after transfemoral transcatheter aortic valve replacement (TF-TAVR) has the potential to identify several pathologies. We investigated the incidence and risk factors of femoral vessel complications in a modern TAVR collective using postinterventional sonography.
Methods: Between September 2017 and March 2022, 480 patients underwent TF-TAVR with postinterventional femoral sonography at a single center.
Purpose: To determine the diagnostic accuracy of preinterventional imaging modalities in patients being evaluated for iliocaval venous recanalization and stent placement.
Methods: Consecutive patients with iliocaval postthrombotic obstructions or nonthrombotic iliac vein lesions (NIVL), who were scheduled for recanalization, underwent duplex ultrasound (DUS), magnetic resonance venography (MRV), multiplanar venography (MPV), and intravascular ultrasound (IVUS). The diagnostic accuracies of DUS, MRV, and MPV were analyzed using IVUS as reference.
Purpose: The purpose of this study was to report the closure of iliac arteriovenous fistulas associated with a post-thrombotic iliac vein occlusion by iliac venous stent recanalization.
Case Report: An 80-year-old woman presented with a worsening painful swelling of her left leg after an iliofemoral deep vein thrombosis 6 months ago. Duplex ultrasound and magnetic resonance venography revealed a post-thrombotic obstruction of her iliac veins as well as several arteriovenous fistulas between branches of her left external and internal iliac arteries and adjacent diseased venous segments.
