Clinical features and prognosis of autosomal dominant polycystic kidney disease with cerebrovascular complications.

Objectives: This retrospective study was used to evaluate the clinical and imaging characteristics and the prognosis of autosomal dominant polycystic kidney disease (ADPKD) with cerebrovascular complications.

Materials and methods: We retrospectively analyzed 30 patients with ADPKD complicated with intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), unruptured intracranial aneurysms (UIAs), or Moyamoya disease (MMD) who were admitted to Jinling Hospital from January 2001 to January 2022. We analyzed the clinical manifestations and imaging characteristics of ADPKD patients with cerebrovascular complications and followed up on their long-term outcomes.

Results: 30 patients, 17 men and 13 women, with an average age of 47.5 (40.0, 54.0) years were included in this study, including 12 cases of ICH, 12 cases of SAH, 5 cases of UIA, and 1 case of MMD. The 8 patients who died during follow-up had a lower Glasgow Coma Scale (GCS) on admission (p = 0.024) and a significantly higher serum creatinine (p = 0.004) and blood urea nitrogen (p = 0.006) than the 22 patients with long-term survival.

Conclusion: Intracranial aneurysms, SAH, and ICH are the most common cerebrovascular diseases in ADPKD. Patients with low GCS score or worse renal function have a poor prognosis, which can lead to disability and even death.
