How many major branches does the external carotid artery
The internal carotid artery is unique in that a large outflow tract, the external carotid artery
, is situated just at its origin.
Variations in the external carotid artery
noted by previous workers are:
5 Some surgeons suggest the ligation of external carotid artery
and its branches in order to reduce the operative complications.
The proximal end of the external carotid artery
was ligated before injection of EPCs or normal saline.
Eca= External carotid artery
, Iaa= Infeior alveolar artery, Ian= Inferior alveolar nerve,
In the event that the vertical segment of the ICA regresses or does not develop, a communication persists between it and the external carotid artery
, which is derived from the second branchial arch.
SUMMARY: Light microscopy analysis of the mural structure of the common carotid artery, internal carotid artery and external carotid artery
in mongrel dog revealed variability in the middle values of vascular diameter and thickness of the intimal plus medial coats and adventitial coat.
The scanning started at distal end of common carotid artery, crotch of common carotid artery, and originated sites of internal carotid artery and external carotid artery
, the scanning durations for each slice T1W, T2W, and PDW were 22, 28, and 38 s, respectively, 4-8 slices were scanned, 60 slices were scanned for 3D-TOF for 2 min and 28 s.
4) Collateral supply is more commonly supplied by circle of Willis, but may also be provided by embryonic vessels or the external carotid artery
The mass was supplied by a proximal external carotid artery
SUMMARY: The lingual artery constitutes one of the branches of the external carotid artery
, which is responsible for the vascularization of the tongue and neighbour regions.
