Ak. Karabulut et al., Saphenous vein graft for bypass of the maxillary to supraclinoid internal carotid artery: An anatomical short study, ANN VASC S, 15(5), 2001, pp. 548-552
The use of a saphenous vein graft for bypass of the maxillary artery (MA) t
o the supraclinoid internal carotid artery (ICA) in internal! carotid: occl
usions is investigated. Five adult cadaver sides were used. Dissection requ
ired zygpmatic arch osteotomy and a pterional craniotomy with extensive rem
oval of the floor of the middle cranial, fossa. The MA was found easily med
ia[ to infratemporal crest. The clinoidal segment of the ICA was exposed wi
th the removal of the anterior clinoid process intradurally. The bypass gra
ft was 4 to 5 cm long and was sutured end-to-end to the MA and end-to-side
to: the supraclinoid ICA. When high blood flow is needed in cases with ICA
occlusion, such a bypass may be an alternative to superficial temporal (STA
)-to-middle cerebral artery (MCA) bypass as well as to common carotid-to-MC
A or-ICA bypass, which needs a long vein graft. This type of bypass will pr
ovide the opportunity to clip the ICA proximal to the origin of ophthalmic
artery, which may inhibit distal embolization.
