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.

Aneurysm of the Posterior Inferior Cerebellar Arteries/Communicating Artery

Cerebrovascular Diseases, 2001
Only 3 cases of aneurysm associated with the communicating artery between both distal posterior inferior cerebellar arteries (PICAs) have been reported in the literature. We present the 4th case of such an aneurysm arising from the communicating artery itself, which is unrelated to the arterial branches.

Trigeminal artery connection to the posterior inferior cerebellar arteries

Neuroradiology, 1975
An example of the internal carotid artery supplying the posterior inferior cerebellar artery directly is reported. The direct PICA supply comes from a trigeminal trunk. There was no basilar artery opacification. An embryological explanation is given.

Posterior Inferior Cerebellar Artery-Posterior Inferior Cerebellar Artery Bypass versus Occipital Artery-Posterior Inferior Cerebellar Artery Bypass for Treating Posterior Circulation Aneurysms: A Systematic Review and Comparative Meta-Analysis

World Neurosurgery
When traditional therapies are unsuitable, revascularization becomes essential for managing posterior inferior cerebellar artery (PICA) or vertebral artery aneurysms. Notably, the PICA-PICA bypass has emerged as a promising option, overshadowing the occipital artery-PICA (OA-PICA) bypass.

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

Surgical Neurology, 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 ...

Three Cerebellar Arteries: Superior Cerebellar Artery, Anterior Inferior Cerebellar Artery, and Posterior Inferior Cerebellar Artery

2014
The three cerebellar arteries comprise superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA), and posterior inferior cerebellar artery (PICA). SCA, AICA, and PICA course around the brainstem, near the three cerebellar peduncles, and in the three cerebellar–brainstem fissures between the cerebellum and brainstem to reach the three
