RESUMO
BACKGROUND: Renal vein stenosis is uncommon following transplantation. We report acute renal vein stenosis post-transplant treated with an endovascular stent and complicated by urinary obstruction from clot formation. METHODS: Retrospective case report. RESULTS: A 16-year-old female 3 years post-transplant suffered anuria post-stenting with renal ultrasound demonstrating obstructive clot in the collecting system, a previously unreported complication. Subsequent nephroureteral JJ stent placement resulted in high-volume urine output. CONCLUSION: This article underscores the high index of suspicion required for renal vein stenosis following transplantation and the need to monitor urine output closely following stent placement.
RESUMO
Pediatric venous occlusions are a growing cause of morbidity and mortality, especially in hospitalized patients. Catheter-directed recanalization is a safe and effective treatment option in appropriately selected patients. Benefits of catheter directed therapies (CDTs) include the prevention of pulmonary embolism and end organ failure acutely as well as superior vena cava syndrome and post-thrombotic syndrome chronically. Timely diagnosis, recognition of underlying factors for thrombosis, and familiarity with the spectrum of tools and techniques for CDT are essential to optimizing outcomes in the acute setting. Recanalization of chronic venous occlusions can similarly provide symptomatic relief and achieve long term vessel patency. This review will detail the scope, techniques, and outcomes for CDT in the treatment of acquired systemic deep vein occlusions.

Mycotic pseudoaneurysm is a rare complication of systemic infection in children. We report a case of a previously healthy 11-year-old female with methicillin-resistant staph aureus (MRSA) bacteremia who developed both pulmonary and systemic arterial pseudoaneurysms. These were detected on magnetic resonance (MR) and computed tomography (CT) imaging and treated with coil embolization.
