PURPOSE To document a case of central retinal artery occlusion after chiropractic treatment. METHODS An 87-year-old man suffered a central retinal artery occlusion immediately after chiropractic neck manipulation. RESULTS A magnetic resonance angiogram showed an atherosclerotic plaque in the ipsilateral carotid artery, which probably shed emboli during cervical joint mobilization. CONCLUS...

Objective: To elucidate the value of early computed tomographic (CT) signs of stroke in predicting the occlusion site in the cerebral arteries. Patients: 105 consecutive patients with acute embolic stroke affecting the anterior circulation. Methods: Four early signs were evaluated on cranial CT within six hours of stroke onset: loss of the insular ribbon (LIR); attenuation of the lentiform nucl...

Opacity Pulse Propagation Measuremen ts in Humans: Atraumatic Screening for Carotid Arterial Occlusion • Opacity pulse propagation times to areas of facial skin supplied by internal carotid (medial supraorbital area) and external carotid arteries (lateral supraorbital areas, cheeks, etc.) were carried out in 27 patients with cerebrovascular symptoms, 16 of whom had normal four-vessel angiograph...

In patients with high-grade atherosclerotic stenosis or occlusion of the extracranial cerebral arteries, subarachnoid hemorrhage (SAH) may occur, potentially due to rupture of fragile dilated pial collateral vessels. This association has been well described in Moyamoya disease. There are only few cases in the literature that reported SAH due to bilateral carotid artery stenosis but intraventric...

Fibromuscular dysplasia (FMD) is a noninflammatory, nonatherosclerotic disorder that cause arterials steno- sis, occlusion, aneurysm, dissection, and artery tortuosity. The etiology of FMD remains unknown. most frequently involved arteries are the renal, internal carotid, vertebral visceral. Among adults, more common in females. Most symptoms renovascular hypertension, headache, pulsatile tinni...

Experiments are presented to show the effects of (1) propranolol on tbe response of systolic blood pressure and diastolic blood pressure to bilateral carotid artery occlusion in choralose-anesthetized dogs; (2) the effects of propranolol on acute hypertensive states in chloralose-anesthetized dogs; and (3) the effects of propranolol on the response of trained awake dogs to bilateral carotid art...

We analyzed the clinical profiles and autopsy findings of five patients who died shortly after developing cerebral infarction following thrombotic occlusion of the internal carotid artery. In all five cases, thrombotic occlusion was caused by rupture of the fibrous lining over the gruel of atheroma at the origin of the internal carotid artery showing tight stenosis of the lumen. The mean±SD sho...

BACKGROUND Common carotid artery (CCA) occlusion sometimes requires surgical revascularization to resolve persistent cerebral/ocular ischemia. High-flow bypass is often indicated in these cases, using the interposed graft such as saphenous vein and radial artery. However, high-flow bypass surgery is invasive and may provide excessive blood flow to ischemic brain. In this report, we present a ca...
