Posterior communicating artery aneurysm associated with duplicated posterior communicating artery and bilateral fetal posterior cerebral arteries.
Because of the location, skull-base chordomas often present with headaches and diplopia and sixth and fifth nerve palsies are the most common neurological signs.[1,2] The interval between onset of symptoms and diagnosis of clival chordoma is quite variable, 2.5-4.4 years.[4] The uncommon clinical presentations include: Nasal obstruction, nasal bleeding, and subarachnoid hemorrhage.[3,5] Spontan...

متن کاملSuccessful Cross-circulation Stent-Retriever Embolectomy Through Posterior Communicating Artery for Acute MCA Occlusion by Using Trevo XP ProVue
Acute ischemic stroke due to embolic occlusion of the middle cerebral artery (MCA) in patients with chronic ipsilateral internal carotid artery (ICA) occlusion is quite rare. Several previous reports demonstrated that intra-arterial (IA) thrombolytic therapy or aspiration thrombectomy using the cross-circulation technique via an alternative collateral pathway is feasible in acute stroke patient...
متن کاملAbsence of right posterior communicating artery
The circle of Willis represents a vascular network located at the base of the skull in the interpeduncular fossa. The anterior cerebral artery forms the anterior section of the circle of Willis from the right and left sides. The anterior cerebral arteries from both sides are joined by the anterior communicating artery. In the posterior part, the basilar artery separates into the right and left ...
متن کاملTuberothalamic artery infarctions following coil embolization of ruptured posterior communicating artery aneurysms with posterior communicating artery sacrifice.
BACKGROUND AND PURPOSE Ischemic complications after coil embolization of the PcomA aneurysms are not thoroughly understood, especially in cases in which the PcomA is sacrificed. Our purpose was to examine the preoperative angiographic features and pattern of postoperative cerebral infarctions exhibited by patients who underwent embolization of ruptured PcomA aneurysms with PcomA sacrifice. MA...
