BackgroundLittle is known about the outcome of endovascular treatment for intracranial aneurysms in patients with autosomal dominant polycystic kidney disease (ADPKD).ObjectiveTo present clinical outcomes in terms of safety, effectiveness, and renal functions to assess contrast-induced nephropathy in endovascular coil embolization for intracranial aneurysms in ADPKD patients.MethodsNineteen ADPKD patients (female:male, 15:4; mean age, 49.8 years; range, 20-67 years) had 26 aneurysms (mean size, 5.86 mm; range, 2.5-11.6 mm) and underwent 22 endovascular treatment sessions from 2001 to 2013. Four patients presented with ruptured aneurysms. Periprocedural complications, clinical outcomes with modified Rankin Scale scores, laboratory findings, and chronic kidney disease (CKD) stage before and after treatment were documented. Acute renal impairment was defined as serum creatinine (Cr) elevation by ≥ 0.5 mg/dL or 25% relative to baseline.ResultsSymptomatic periprocedural complications developed after 1 endovascular procedure (1 of 22, 4.5%), and good clinical outcomes (modified Rankin Scale scores, 0-1) were achieved in 90% of patients (17 of 19). Overall, acute renal impairment occurred in 9.1% of treatment sessions (2 of 22). Acute renal impairment developed in 25% of high-risk patients (baseline Cr > 2.0 mg/dL) and 33.3% of baseline CKD stage 5 sessions but in none of the low-risk patients (baseline Cr ≤ 2.0 mg/dL) and in no CKD stage 1 to 4 sessions.ConclusionWith appropriate management, coil embolization may be safe and effective for intracranial aneurysms in ADPKD. There is a concern about contrast-induced nephropathy in patients with CKD stage 5 or high serum Cr level (>2.0 mg/dL).
