Two patients had multiple embolic infarctions in the middle cerebral artery territory. Free-floating thrombi adherent to plaques were detected in the common carotid artery near the bifurcation using duplex ultrasonography. Further strokes did not occur under anticoagulation. The free-floating thrombi disappeared on follow-up sonography. Carotid duplex ultrasonography is useful for recognizing f...

Background: Carotid body tumours (CBTs) are rare that arise from chemoreceptor cells at the bifurcation of carotid artery. Excision CBT poses several anesthetic challenges and may be complicated with marked intraoperative hemodynamic instability turbulent postoperative recovery. Attention to details a meticulous plan essential for successful management. Aim: To present anaesthetic management tu...

A 33-year-old woman was admitted to our hospital with a slow-growing mass in the left side of her neck. The mass was found to be a huge (73 × 56 × 54 mm) carotid body paraganglioma. Another 21 mm-size tumor was incidentally detected at the right carotid bifurcation. She had hoarseness and Horner's syndrome of her left side. Both tumors were surgically removed. There were no cerebrovascular comp...

We analyze the AneuRisk65 curvature functions using a likelihoodbased warping method for sparsely sampled curves, and combine it with logistic regression in order to discriminate subjects with aneurysms at or after the terminal bifurcation of the internal carotid artery (the most life-threatening) from subjects with no aneurysms or aneurysms along the carotid artery (the less serious). Signific...

Background 3D black-blood MRI is a promising imaging modality for carotid artery wall imaging but is inherently susceptible to motion. Previous work shown that swallowing can result in the greatest motion at the carotid bifurcation and its vicinity (1). A self-gating (SG) method in combination with a 3D variable-flip-angle turbo spinecho sequence, SPACE, has recently been proposed for gating sw...

Sixty carotid bifurcations in 34 symptomatic patients were examined prospectively with ultrasound (continuous wave Doppler and high resolution, B-mode imaging) and intravenous digital subtraction angiography (IV-DSA). The overall quality of examination was better with DSA than with ultrasound. Imaging of the external carotid artery was particularly difficult with sonography. For evaluation of t...
