Technical strategies to approach aneurysms of the vertebral and posterior inferior cerebellar arteries.
OBJECT Aneurysms of the vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) are rare and challenging lesions, as they are located in front of the brainstem and surrounded by the lower cranial nerves. Many different approaches have been described for their treatment, and have yielded different results. With the use of different examples of lesions, the authors describe...
متن کاملDissecting aneurysms of the distal segment of the posterior inferior cerebellar arteries: clinical presentation and management.
BACKGROUND AND PURPOSE Dissecting aneurysms of the distal segment of the PICA are rare. The purpose of this study was to evaluate the clinical presentations, imaging features, treatment options, and clinical outcomes of dissecting PICA aneurysms. MATERIALS AND METHODS Six patients with dissecting aneurysms in the distal segments of PICA were found in the database of a single medical center, f...
متن کاملEndovascular treatment of ruptured vertebral artery dissecting aneurysms involving the posterior inferior cerebellar artery.
Dissecting Aneurysms Involving the Posterior Inferior Cerebellar Artery We read the article of Kim et al entitled “Stenting from the Vertebral Artery to the Posterior Inferior Cerebellar Artery” with special interest. In their series, 2 patients had vertebral artery (VA) dissecting aneurysms involving the posterior inferior cerebellar artery (PICA) origin. The authors used VA-to-PICA stent plac...
متن کاملTherapeutic Progress in Treating Vertebral Dissecting Aneurysms Involving the Posterior Inferior Cerebellar Artery
Among the variations of vertebral artery dissecting aneurysms (VDAs), VDAs involving the posterior inferior cerebellar artery (PICA), especially ruptured and high-risk unruptured aneurysms, are the most difficult to treat. Because the PICA is an important structure, serious symptoms may occur after its occlusion. Retained PICAs are prone to re-bleeding because VDAs are difficult to completely o...
متن کاملThe Endovascular Management of Saccular Posterior Inferior Cerebellar Artery Aneurysms
OBJECTIVE The purpose of this retrospective study was to report the outcome of the endovascular treatment of eight patients with eight saccular posterior inferior cerebellar artery (PICA) aneurysms. MATERIALS AND METHODS Over the last seven years (1999-2006), eight consecutive patients with saccular PICA aneurysms were treated by endovascular methods. Five of the aneurysms were presented with...
