Treatment of vertebral artery aneurysms with posterior inferior cerebellar artery-posterior inferior cerebellar artery anastomosis combined with parent artery occlusion

World Neurosurgery, 2004
In patients with aneurysms that involve the origin of the posterior inferior cerebellar artery (PICA) and require occlusion of the vertebral artery (VA), revascularization of the PICA is commonly performed. We present six patients with dissecting VA aneurysms who underwent PICA-PICA anastomosis combined with parent artery occlusion.After a lower ...

Extradural Posterior Inferior Cerebellar Artery

Journal of Neurosurgery, 2000
We read with great interest the paper by Fine and colleagues (Fine AD, Cardosa A, Rhoton AL: Microsurgical anatomy of the extracranial–extradural origin of the posterior inferior cerebellar artery. J Neurosurg 91:645–652, October, 1999). The authors have provided an excellent anatomical description of the extradural–extracranial posterior inferior ...

Double posterior inferior cerebellar artery

Surgical and Radiologic Anatomy, 2009
Posterior inferior cerebellar artery (PICA) is one of the cerebellar arteries which originates from the vertebral artery and has the most complex and variable course. It usually originates from the vertebral artery intracranially and as a single trunk; however, absent, double trunk, extracranial, and extradural PICA may exists although very rare.

The bihemispheric posterior inferior cerebellar artery

Neuroradiology, 2005
Rarely, a solitary posterior inferior cerebellar artery (PICA) will supply both cerebellar hemispheres. We report four cases of this variant. We present a retrospective review of clinical information and imaging of patients undergoing angiography at our institution to identify patients with a bihemispheric PICA.

Thrombotic Aneurysm of Posterior Inferior Cerebellar Artery

World Neurosurgery, 2019
Spontaneous thrombosis of an intracranial aneurysm is rare but is common in fusiform or large cystic aneurysms, which result in subarachnoid hemorrhage after rupture. This case reports a 47-year-old woman with subarachnoid hemorrhage who developed spontaneous thrombosis of an aneurysm due to rupture of the posterior inferior cerebellar aneurysm.The ...

Posterior Inferior Cerebellar Artery-Vertebral Artery Bypass

2021
Intracranial-intracranial (IC-IC) bypass could be a feasible option when the V4 is long enough and the posterior inferior cerebellar artery (PICA)-vertebral artery (VA) can be transected and reimplanted into the V4 using an end-to-side anastomosis technique.

Occipital Artery-Posterior Inferior Cerebellar Artery Bypass

2021
Occipital artery (OA)-posterior inferior cerebellar artery (PICA) anastomosis was introduced as a crucial cerebral revascularization technique for the posterior circulation in the 1970s. The most suitable indications for OA-PICA bypass are complex and giant intracranial aneurysms involving the major vessels of the posterior circulation that cannot be ...

Cerebral revascularization performed using posterior inferior cerebellar artery—posterior inferior cerebellar artery bypass

Journal of Neurosurgery, 2002
✓ Cerebral revascularization is often required for the surgical treatment of complex intracranial aneurysms. In certain anatomical locations, vascular anatomy and redundancy make in situ bypass possible. The authors present four patients who underwent revascularization performed using the rarely reported posterior inferior cerebellar artery (PICA)—PICA

Dissecting Aneurysms of the Posterior Inferior Cerebellar Artery

Neurosurgery, 1991
Abstract The authors present three cases of dissecting aneurysms of the posterior inferior cerebellar artery (PICA). A literature search revealed only three previous cases. Analysis of these six cases showed a unique clinical picture. Three patients developed subarachnoid hemorrhage, and the other three had ischemia.
