A Rare Etiology of Gastrointestinal Bleeding: Polycystic Kidney Disease

Abstract

The major extrarenal complications of autosomal dominant polycystic kidney disease (ADPKD) are aneurysms, hepatic and pancreatic cysts, cardiac valve disease, colonic diverticula, abdominal wall and inguinal hernia and seminal vesicle cysts. We aimed to present that a gastrointestinal bleeding caused by pseudoaneurysm of rupture of a gastroduodenal artery in a patient with ADPKD. A 74 years old geriatric patient with history of ADPKD and chronic kidney disease (CKD) presented with gastrointestinal bleeding symptoms. The endoscopy and colonoscopy were performed after the patient was stabilized but we could not detect any bleeding focus. So that we planned computed tomographic angiography. There was pseudoaneurysmatic expansion and active extravasation from gastroduodenal artery (GDA). We also detected cortical renal cysts in kidneys reaching up to 5 cm compatible with ADPK. After computed tomographic angiography, the opening of the branch leading to extravasation was selectively catheterized Extravasation was not seen in control angiography. There was not hemoglobin decreasing and hemodialysis was continued routinely three times a week. After that the patient discharged. We discussed that a life-threatening complication of ADPKD. This case is important due to see very rarely and being very mortally.
