the branches of external carotid artery were dissected and studied in six one humped camels.these specimens were preparated from slaughterhouse and fixed in10% formaline. the common carotid artery in one humped camel is divided into three branches , including , occipital artery , internal carotid artery and external carotid artery which in this respect it was similar to that of equine. external...
the carotid sinus is a modification in the vascular wall near the bifurcation each common carotid artery and acts as baroreceptor. in this study 16 adult and apparently healthy buffaloes ie. 8 male and 8 female used for the as well as macroscopic orientation microscopic study of the carotid sinus. our study revealed that in the buffalo, carotid sinus is a dilatation in common carotid artery at ...
Introduction: Penetrating trauma to anterior neck can induce cerebral ischemia due to carotid artery injury. Brain ischemia also can present after surgical carotid repairs. Early diagnosis and suitable treatment modality prevent from permanent neurologic deficit post operatively. Case Report: A 30 years old man with stab wound to zone two left side of neck underwent exploration and penrose i...
mycotic aneurysm of external carotid artery is extremely rare. we herein report a case of external carotid artery (eca) aneurysm following severe traumatic brain injury. a 24-year-old man with severe traumatic brain injury (tbi) following a car accident was referred to rajaee trauma center emergency room affiliated to shiraz university of medical sciences in shiraz, iran. he underwent ventricul...
variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...
Since it is too vital to the prevention of carotid disease in the vascular system, it seems necessary to the estimation of the elastic behavior of the carotid artery in head and neck external radiotherapy. In the present study, a total of 24 neck carcinoma patients treated with external radiotherapy had been studied. The carotid mean dose values were determined for each case by contouring the c...
Naturally occurring collatera l pathways con necting the external carotid artery branches and the intracran ial cerebral circulation are well recognized and have been demonstrated anatomically, angiographically, and physiologically by vari ous flow detection devices. Under normal c ircumstances, all internal carotid artery blood flow is direc ted intracranially, and flow through the co ll ater...
the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...
The external carotid artery and its branches were investigated in hens by an acrylic plastic injection method. The common carotid artery of hens bifurcated into the internal and external carotid arteries at the level of the second cervical vertebra. The external carotid artery advanced antero-superiorly within the platysma, stylohyoid, and occipitomandibular muscles at the postero-lateral side ...
