Abstract
BACKGROUND: Very few data stratify the functional outcome of ruptured posterior communicating artery (PCoA) aneurysm treatment based on each treatment strategy. Therefore, the authors aimed to evaluate the outcome of PCoA aneurysm treatment to compare the clipping and coiling techniques and find the factors that determined the treatment outcomes. METHODS: Patients with ruptured PCoA aneurysm at Songklanagarind Hospital between November 2002 and March 2018 were retrospectively reviewed and classified into the clipping group or the coiling group. The primary outcome was the modified Rankin Scale (mRS) at 6 months after treatment, and the patients were stratified into "good outcome" (mRS 0-2) and "poor outcome" (mRS 3-6). Using logistic regression analysis, various factors were analyzed for association with the treatment outcome. RESULTS: This study included 189 patients: 104 and 85 patients in the clipping and coiling groups, respectively. Patients in the coiling group were significantly older, with more underlying diseases. However, the treatment outcomes at 6 months were not significantly different between the 2 groups. The percentages of poor outcomes in the clipping and coiling groups were 28% and 31%, respectively (P = 0.734). Older age, seizure, higher Hunt and Hess grade, deterioration before aneurysm obliteration, an aneurysm on the left side, and a medially projected PCoA aneurysm were statistically significantly correlated with poor outcomes. CONCLUSIONS: Neurosurgical clipping and endovascular coiling are effective treatments for aneurysm obliteration in ruptured PCoA aneurysm. An aneurysm on the left side and a medially projected PCoA aneurysm were the factors correlated with poor outcome.
