During color Doppler examination of a 41-year-old man who presented with vertigo, a right vertebral artery could not be found. Both MR angiography and digital subtraction angiography revealed a large anastomotic vessel between the right internal carotid and vertebral artery. It was thought to be type I proatlantal artery. Furthermore, the external carotid arteries were bilaterally absent. Altho...

was introduced into brachiocephalic angioplasty. This report is based on 299 performed angioplasty procedures. This number is divided as follows: innominate artery 7 (2 with stents), left subclavian artery 49 (15 with stents), right subclavian artery 18 (5 with stents), left common carotid artery 12 (6 with stents), right common carotid artery 5 (3 with stents), external carotid artery 21 (1 wi...

Arterial selection for reference time-enhancement curve generation in deconvolution-based perfusion CT (PCT) studies of the head and neck is under-evaluated. This study of 11 patients with confirmed head and neck squamous cell carcinoma demonstrates significant correlation (range, r = 0.85-0.95) between perfusion parameter values derived with internal carotid artery (ICA) as compared to an exte...

conclusions the relationship between cac found on dental panoramic radiographs and two cva risk factors--hypertension and mi-- was significant. therefore, it seems that detection of cac on panoramic images of dental patients must be considered by dentists. results among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. in total, 5...

Sir, Carotid artery aneurysm is a rare cause of asymptomatic neck mass, which is very often misdiagnosed and underappreciated. We report a case of 57-year-old male patient presented with asymptomatic left sided neck swelling. Examination revealed a firm, non‐tender, non‐pulsatile 6 cm × 4 cm ellipsoid swelling with the presence of carotid bruit [Figure 1]. Computed tomography angiogram and reco...

Although atherosclerosis has been widely investigated at carotid artery bifurcation, there is a lack of morphometric and hemodynamic data at different stages of the disease. The purpose of this study was to determine the lesion difference in patients with carotid artery disease compared with healthy control subjects. The three-dimensional (3D) geometry of carotid artery bifurcation was reconstr...

Middle cerebral artery occlusion (MCAO) by the intraluminal suture method is widely used to model ischemic stroke in rats. Current methods include transection or ligation of the external carotid or common carotid artery and thus result in partial restoration of perfusion after transient MCAO. Since incomplete reperfusion may influence recovery and thus confound studies of the impact of neuropro...

The rate of growth of the left common carotid artery during gestation has not been sufficiently evaluated. The present study was performed on 128 spontaneously aborted human foetuses aged 15-34 weeks to compile normative data for the dimensions of the left common carotid artery at varying gestational ages. Using anatomical dissection, digital image analysis (system of Leica Q Win Pro 16) and st...

OBJECTIVE Surgical resection of complex glomus vagale tumors can be complicated by extensive blood loss and might require surgical sacrifice of an encased internal carotid artery. METHODS A young patient presented with mass effect from glomus valage tumor. Computerized tomography angiography showed an encased internal carotid artery. Cerebral angiography demonstrated a highly vascular tumor....
