Abstract
INTRODUCTION/ PURPOSE: Flow diversion has allowed cerebrovascular neurosurgeons and neurointerventionalists to treat complex, large aneurysms, previously treated with trapping, bypass, and/or parent vessel sacrifice. However, a minority of aneurysms remain that cannot be treated endovascularly, and microsurgical treatment is too dangerous. However, balloon test occlusion (macro and micro), micro WADA testing, ICG, intra-angiography and intra-operative monitoring are all available to clinically test the hypothesis that vessel sacrifice is safe. We describe a dual-institution series of aneurysms successfully treated with parent vessel occlusion (PVO). MATERIALS/ METHODS: Prospectively collected databases of all endovascular and open cerebrovascular cases performed at Maine Medical Center and Vanderbilt University Medical Center from 2011 to 2013 were screened for patients treated with primary vessel sacrifice. A total of 817 patients were screened and 17 patients were identified who underwent parent vessel sacrifice as primary treatment. RESULTS: All 17 patients primarily treated with PVO are described below. Nine patients presented with SAH, and 3/17 involved anterior circulation. Complete occlusion was achieved in 15/17 patients. In the remaining 2 patients, significant reduction in the aneurysm occurred. Modified Rankin Score (mRS) of 0, signifying complete independence, was achieved for 16/17 patients. One patient died due to an extracranial process. CONCLUSIONS: Parent vessel sacrifice remains a viable and durable solution in select ruptured and unruptured intracranial aneurysms. Many adjuncts are available to aid in the decision making. In this small series, patients naturally divided into vertebral dissecting aneurysms, giant aneurysms and small distal aneurysms. Outcomes were favorable in this highly selected group.
