Attention To Detail

Occipital artery to posterior inferior cerebellar artery bypasses remain an important tool for cerebrovascular neurosurgeons, particularly in the management of complex aneurysms of the posterior inferior cerebellar artery requiring proximal occlusion or trapping. The procedure requires meticulous technique and attention to detail. The authors outline their technique for accomplishing this bypass emphasizing nuances for complication avoidance.

Treatment Considerations

The posterior inferior cerebellar artery (PICA) is a vessel located between the intra- and extracranial circulation. The artery is characterized by a complex embryological development and numerous anatomical variants. The authors present a case of the PICA supplied by both a hypertrophic anterior spinal artery and a hypoplastic bulbar artery. This unusual arrangement somehow completes the list of previously published variants, and the spontaneous rupture of a related aneurysm confirmed the fragility of this network. The authors discuss anatomical and treatment considerations.

Technical Considerations

AbstractNonsaccular vertebral artery aneurysms involving the posterior inferior cerebellar artery (PICA) are rare. Treatment is considered a significant challenge because of their angiographic and anatomical features, especially in high-riding PICA. Therefore, meticulous preoperative angiographic and anatomical evaluation is necessary. Moreover, consideration of the distance between the cerebellar skull base and caudal loop of the PICA is important. We present two cases of occipital artery-high-riding PICA bypass and discuss important preoperative technical considerations.

Arterial Bypass Graft

We provide a case report of a 58-year-old man who presented with a ruptured fusiform dissecting aneurysm located at the junction of the vertebral artery and posterior inferior cerebellar artery (PICA). Due to the lesion’s complexity, a two-step approach was planned for revascularisation of PICA using the occipital artery (OA) prior to coiling embolisation. An end-to-side OA–PICA bypass was performed with implantation at the caudal loop of the p3 PICA segment. Fifteen days after the procedure, the aneurysm underwent stent-assisted coiling for successful obliteration of the aneurysm. The patient tolerated this procedure well and now at 1.5 years of follow-up remains free from any neurological deficits (modified Rankin Score 0). This case report illustrates one of the unique scenarios where both the vascular territory involved and morphological features of the aneurysm prohibited the use of more conventional means, necessitating the use of an arterial bypass graft for successful treatment of this lesion. As open vascular surgery is becoming less common in the age of endovascular coiling, our article uniquely reports on the combined use of both endovascular and microsurgical techniques to treat a complex aneurysm of the posterior circulation.

Noticeable Improvement

Abstract Fourteen patients who underwent occipital to posterior inferior cerebellar arterial bypass are reviewed. All of the patients were treated for severe vertebrobasilar ischemia secondary to lesions of the distal vertebral artery. There was no operative death or permanent postoperative morbidity. On follow-up evaluation (averaging 13 months after operation), there has been 100% graft patency and a noticeable improvement in the neurological function in all patients. Operating with the patient in the prone position and avoiding intraoperative hypotension help to minimize the operative morbidity from this procedure.
