Distal superficial temporal artery to proximal posterior cerebral artery bypass by posterior oblique transzygomatic subtemporal approach.
This article investigates the possibility for the distal superficial temporal artery (STA) to proximal posterior cerebral artery (PCA) direct bypass by subtemporal oblique posterior transzygomatic approach. Five adult cadaveric specimens were dissected. Cadeveric dissection protocol was approved by the Research Ethics Committee. A preauricular vertical skin incision was made, the trunk of STA w...
متن کاملSuperficial temporal artery to proximal posterior cerebral artery bypass through the anterior temporal approach
BACKGROUND The superficial temporal artery (STA) to proximal posterior cerebral artery (PCA) (P2 segment) bypass is one of the most difficult procedures to perform because the proximal PCA is located deep and high within the ambient cistern. STA to proximal PCA bypass is usually performed through a subtemporal approach or posterior transpetrosal approach, and rarely through a transsylvian appro...
متن کاملTranszygomatic-Subtemporal Approach for Middle Meningeal-to-P2 Segment of the Posterior Cerebral Artery Bypass: An Anatomical and Technical Study.
We evaluated the use of a bypass between the middle meningeal artery (MMA) and P2 segment of the posterior cerebral artery (PCA) as an alternative to an external carotid artery (ECA-to-PCA) anastomosis. Five adult cadaveric heads (10 sides) were used. After a temporal craniotomy and zygomatic arch osteotomy were performed, the dura of the floor of the middle cranial fossa was separated and elev...
متن کاملA calcified superficial temporal artery to posterior cerebral artery bypass mimicking occlusion.
A 65-year-old man had progressive vertebrobasilar insufficiency, including cerebellar infarction, despite aggressive use of antiplatelet agents (aspirin, dipyridamole) and anticoagulants (heparin, Coumadin). Angiography showed 99% stenosis at the origin of the right vertebral artery and 99% stenosis of the basilar artery proximal to both superior cerebellar arteries. Because the patient 's sign...
متن کاملPosterior Auricular Artery-Middle Cerebral Artery Bypass: A Rare Superficial Temporal Artery Variant with Well-developed Posterior Auricular Artery—Case Report
The posterior auricular artery (PAA) is one of the branches of the external carotid artery, but is usually too small for use as a donor artery for middle cerebral artery (MCA) territory revascularization. An extremely unusual case of PAA-MCA anastomosis was performed in a patient requiring MCA territory revascularization because the superficial temporal artery (STA) parietal branch was absent a...
