Abstract Background: Minor bleeding after prostate biopsy is a relatively common complication, but clinically significant hemorrhage happens rarely. Management of prostatic artery pseudoaneurysm has not been described in the literature. Case Description: In this case, an 84-year-old man presented after prostate biopsy with rectal bleeding and required a massive transfusion. Ultimately, he was found to have a prostatic artery pseudoaneurysm, which to our knowledge is heretofore undescribed after prostate biopsy. Bleeding ultimately stopped spontaneously as the patient deferred angioembolization. He had not recurrent bleeding on follow up but is still deciding on treatment course for newly diagnosed More >

Abstract Background: Carotid artery pseudoaneurysm in children is rare; typically caused by trauma; surgical interventions and infection. These aneurysms can lead to significant neurological and vascular risks; and their management remains challenging. While endovascular therapy has become the standard for giant pseudoaneurysms in adults; its use in children is limited. No established guidelines or long-term safety data exist for pediatric endovascular treatment. We present a child who developed a carotid artery pseudoaneurysm after venoarterial extracorporeal membrane oxygenation (VA-ECMO) support and heart transplantation; highlighting the management strategies and outcomes. Case Description: A 4-year-old boy with dilated cardiomyopathy was admitted… More >

Abstract Background: Pseudoaneurysm complicating right ventricular outflow tract (RVOT) with conduit placement was an infrequent complication but with potential for significant morbidity and mortality, and a more unusual pseudoaneurysm after RVOT patching was investigated here. Methods: Patients diagnosed as pseudoaneurysms at our institution from 2010 to 2019 were reviewed and their clinical characteristics were analyzed. Results: A total of seven patients developed pseudoaneurysm in RVOT were identified. One pseudoaneurysm arose after placement of a conduit between the right ventricle and the pulmonary artery, and the other six formed after RVOT patching. One patient presented with arrhythmia, one patient… More >

Abstract Renal pseudoaneurysm following ureteroscopy is a rare cause of hematuria usually diagnosed and treated with angiography and embolization. Here we present a case of a small pseudoaneurysm causing intermittent flank pain and gross hematuria associated with clot retention initially diagnosed during ureteroscopy and subsequently treated with a combined endourologic and endovascular approach.

Abstract A65-year-old female presented to clinic requesting follow up for a history of right robotic partial nephrectomy done at an outside institution 2 years prior. Initial pathology demonstrated a grade 2/4 3.4 cm clear cell renal cell carcinoma with negative margins. There was no tumor necrosis, sarcomatoid differentiation, or lymphovascular invasion. High quality follow up imaging initially revealed a pseudoaneurysm in the central portion of the right kidney. The patient was sent to interventional radiology for angioembolization. Angiography identifed the abnormality to be a recurrent or residual mass in the renal hilum. MRI confrmed these fndings, More >

Abstract Renal artery pseudoaneurysms (RAPs) are vascular lesions that have most commonly been reported secondary to penetrating renal trauma and iatrogenic injury. We present the fi rst case of a RAP that developed as a result of an isolated deceleration injury. The patient presented 3 years after his injury with symptoms of gross hematuria, right fl ank pain, and syncope. Diagnosis of his RAP was made by magnetic resonance imaging (MRI) and angiography. He was successfully treated with angioembolization. More >

Abstract We report a case of a 19-year-old female who presented with right flank pain and microscopic hematuria.Three years earlier, she sustained a stab wound to the right flank and was managed conservatively. After being diagnosed with an enhancing renal mass using computed tomography (CT) scan, duplex ultrasound and angiography were performed revealing an intrarenal pseudoaneurysm. Endovascular coils were successfully employed to selectively embolize the pseudoaneurysm. More >

Abstract Percutaneous renal surgen; can be utilized as treatment for a variety of urologic conditions. Percutaneous nephrolithotomy remains the treatment of choice for many large and complex renal calculi. Despite having a low overall complication rate, postoperative bleeding can occur. We report a case of significant hemorrhage from a renal pseduoaneurysm in a patient requiring anticoagulation following percutaneous nephrolithotomy. The bleeding was controlled by percutaneous coil embolization. Current management recommendations of postoperative hemorrhage following percutaneous renal surgery are reviewed. More >
