Background: Renal vein aneurysms (RVAs) are uncommon entities, which are usually incidental findings or may cause mild nonspecific symptoms. Modern radiological imaging, mainly multislice computed tomography (CT), has substantially contributed to a prompt and accurate diagnosis. Treatment may range from watchful waiting to aneurysmorraphy, aneurysmectomy, and nephrectomy. Potential complications include thrombosis, pulmonary embolism, pressure to other structures, and rupture.
Case: A 58-year-old male patient was admitted at the emergency department with abdominal pain. He underwent an emergency CT scan which showed a huge retroperitoneal hematoma around the right kidney, while soon afterward he had a hypovolemic shock, less than an hour after a temporary loss of consciousness after an acute emotional distress episode. He underwent an emergency laparotomy and a right nephrectomy because of an RVA. Interestingly, his postoperative course was uneventful and his six-month follow-up was normal.
Discussion: This report presents the rupture of an RVA for the first time, which was successfully treated through nephrectomy by general surgeons in a secondary hospital. This is a catastrophic event which may be lethal, in case prompt diagnosis and surgical intervention delay. Due to the rarity of the disease, its etiology and optimal treatment remain to be clarified.
