“…This type of aneurysm is rare, and whether it is safe to occlude the aneurysm and parent artery in cases of a ruptured aneurysm of the hypoplastic and plexiform PICA has not been adequately studied and is still open to debate (4,5). In this report, we report 2 cases of ruptured aneurysms of a hypoplastic and plexiform PICA.…”

Aneurysms arising from the posterior inferior cerebellar artery (PICA) are not rare and may originate from the proximal or peripheral segment of the PICA. However, when the affected PICA is hypoplastic and plexiform, it is difficult to occlude the aneurysm without sacrificing the parent vessel, the PICA. This type of aneurysm is rare, and whether it is safe to occlude the aneurysm and the parent artery, in cases of a ruptured aneurysm of the hypoplastic and plexiform PICA, has not been adequately studied and is still open to debate. In this report, two patients with ruptured aneurysms in the hypoplastic and plexiform PICA were presented. Both patients were admitted to our hospital for subarachnoid hemorrhage. After team discussions between the neurosurgeons and neurointerventionalists, the aneurysm and parent PICA had to be occluded via endovascular treatment under general anesthesia. One of the patients developed postprocedural brainstem infarction and exhibited favorable recovery. The other patient died of pulmonary infection, although improvement in the postoperative state was observed. Although rare, aneurysms can originate from the hypoplastic and plexiform PICA. Occluding the aneurysm and hypoplastic parent PICA via endovascular treatment might be a reasonable option.

“…Anterior medüller segmentteki anevrizmalar proksimal PICA, lateral medüller segmentte yer alanlar ise lateral PICA anevrizmaları olarak adlandırılırlar. Beyin sapı ve alt kranial sinirler ile yakın ilişkisi nedeniyle özellikle proksimal PICA anevrizmalarının tedavisinde güçlükler mevcuttur [9]. PICA proksimalinde sıklıkla mevcut olan sert loop sebebi ile bu bölgede ayrıca zorluk oluşur.…”

“…Aneurysms of the posterior inferior cerebellar artery (PICA) accounts for 0.5%–3.0% of all intracranial aneurysms. [ 1 ] Most of the PICA aneurysms originate from the vertebral artery (VA)-PICA junction. [ 2 ] Direct surgical therapy of the aneurysms is difficult because of the intimate relationship between PICA and the medulla.…”

Aneurysms located in the posterior inferior cerebellar artery (PICA) are not a majority of the intracranial aneurysms cases. Many challenges were addressed in the endovascular procedure to treat the disease. The authors have successfully diagnosed and treated a ruptured proximal PICA aneurysm. However, digital subtraction angiography showed acute thrombosis in the vertebral artery in the procedure, which probably could be an acute in-stent thrombosis. The tirofiban hydrochloride injection was subjected through a microcatheter, and then, the second Neuroform EZ stent was planted. In the 6-month follow-up, no recurrence of the aneurysm and complete patency of the right PICA at the site of aneurysm formation were found. We believe that the treatment of PICA aneurysms with Neuroform EZ stents could get a favorable result. Combination of tirofiban hydrochloride and Neuroform EZ stent could be an effective approach in treating acute thrombotic complications.
