Congenital renal arteriovenous malformation presenting with gross hematuria after a routine jog: a case report.

Introduction: Congenital renal arteriovenous malformations are abnormal communications between the intrarenal venous and arterial systems. An unusual cause of massive gross hematuria and an even rarer cause of hemodynamically significant anemia, its presentation remains variable from incidental imaging findings to severe hypertension and congestive heart failure.

Case Presentation: We present a case of a 44-year-old Chinese man with no personal or familial history of bleeding diasthesis that presented with gross hematuria leading to clot retention after routine physical activity.

Radioembolization with infusion of yttrium-90 microspheres into a right inferior phrenic artery with hepatic tumor supply is feasible and safe.

Purpose: To evaluate the feasibility and safety of yttrium-90 ((90)Y) radioembolization through the inferior phrenic arteries (IPAs).

Materials And Methods: Retrospective analysis of 108 patients referred for radioembolization to treat primary (n = 103) or secondary (n = 5) liver malignancy was performed. Five patients had malignant hepatic tumors supplied by the IPA and met criteria for infusion of (90)Y spheres into the IPA.
