Background/Aims: Subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH) are two subtypes of hemorrhagic stroke that may cause severe complications in patients with autosomal-dominant polycystic kidney disease (ADPKD). The differences in clinical features between SAH and ICH associated with ADPKD are not known. Methods: Among 647 ADPKD patients hospitalized between 1997 and 2007 in our hospital, 11 with ICH (1.7%) and 6 with SAH (0.9%) were identified. Results: Patients with SAH were significantly younger than patients with ICH (39 ± 6 vs. 57 ± 15 years, p = 0.013). The systolic blood pressure on admission was significantly higher in patients with ICH (194 ± 26 vs. 145 ± 18 mm Hg, p = 0.001). Two patients (18.2%) with ICH died after a first episode, 6 had a second episode, and 2 had a third episode. Two patients (33.3%) with SAH died after a first episode but the survivors had no recurrence during follow-up. The 30-day survival curves comparing patients with ICH and SAH were not significantly different. Patients with a Glasgow Coma Score less than 9 on arrival had a significantly worse outcome. Conclusion: Clinical features differed between ICH and SAH associated with ADPKD. Nevertheless, blood pressure control and early recognition of hemorrhagic stroke are important in ADPKD patients.
