Aneurysms of Distal Posterior Inferior Cerebellar Artery

Endovascular Treatment of Ruptured Distal Posterior Inferior Cerebellar Artery Aneurysm. Report of Two Exemplary Cases and Retrospective Analysis of 11 Cases

“…The reported mean age of patients who present with distal PICA aneurysm is the fifth and sixth decades of life, generally younger than that of patients with aneurysms at other locations. 1,17,19,20 However, the mean age of our series is 56.3 years, which is somewhat higher than that given in previous reports and similar to aneurysms located in vascular anatomy other than the PICA. This difference could result from the fact that we excluded unruptured incidental aneurysms that were included in previous reports.…”

Parent artery occlusion with Onyx for distal aneurysms of posterior inferior cerebellar artery: A single-centre experience in a series of 15 patients

“…In addition, distal PICA aneurysms are uncommon and PICA shows many varied morphology. [9] Because of these facts, endovascular treatment is suggested as an alternative treatment option. Strategies of endovascular treatment for distal PICA aneurysm include embolization with parent artery preservation and PAO.…”

Flow-Diverter Stent for the Treatment of a Non-Origin Posterior Inferior Cerebellar Artery Aneurysm

“…Most of them arise near the origin of the PICA from the vertebral artery 3 . Distal PICA aneurysms are very rare, and account for approximately 0.3% of all PICA aneurysms 4 . PICA aneurysms commonly occur in patients in their fifth and sixth decades without gender predilection.…”

“…PICA aneurysms commonly occur in patients in their fifth and sixth decades without gender predilection. The clinical presentations of ruptured PICA aneurysms are variable and include a sudden onset of severe headache (the suboccipital area in particular), mental status change, syncope, and meningeal irritation 4 . Treatment options for aneurysms in general and PICA aneurysms in particular include surgical clipping or wrapping or alternatively endovascular interventions.…”
