There are two types of PKD: autosomal dominant polycystic kidney disease ADPKD and the less-common autosomal recessive polycystic kidney disease ARPKD. Major extrarenal complications of ADPKD are: Cerebral aneurysms; Hepatic and pancreatic cysts; Cardiac valve disease; Colonic diverticula; Abdominal wall and inguinal hernia. Malformations of selected vasculature, including intracranial aneurysms and aortic root dilatation normal diamete 35 mm, may be due to altered expression andor function of the PKD gene in arterial smooth muscle cells. Cervicocephalic artery dissections, dolichoectasias, and central retinal vascular occlusions have also been associated with ADPKD. CEREBRAL ANEURYSM: A ruptured cerebral aneurysm, resulting in a subarachnoid or intracerebral hemorrhage, is the most serious complication of polycystic kidney disease. The prevalence of aneurysms in ADPKD is approximately 5 percent in young adults and increases with age to as high as 20 percent in patients 60 years and older.
