Computed tomography scan in the evaluation of patients with stroke

Abstract

ABSTRACT ABSTRACT ABSTRACTCerebrovascular accident is a frequent cause of death and disability in most parts of the globe. The incidence of cerebrovascular diseases increases with age and the number of strokes is projected to increase as the elderly population grows. This study was undertaken to determine the type of stroke and also to relate the risks factors associated with stroke. Hundred consecutive patients presenting with stroke in the emergency department / neurology clinic were subjected to computed tomography scan of the brain. Sixty -four patients had ischemic infarct and 36 had intracranial hemorrhage which included 2 patients with subarachnoid hemorrhage and 1 with underlying cavernous angioma. Ischemic stroke was thus commoner than hemorrhagic stroke. Previous infarct or lacunes were noted in 25 % of the patients presenting with stroke. Risk factors were present in most (77 %) of the patients presenting with stroke. Among the various risk factors, the single most common was smoking seen in 38 cases, followed by hypertension in 28 cases, obesity in 8 cases and diabetes in 3 cases. Twenty-one patients had multiple combinations of the above risk factors. Among the multiple risk factors, combination of alcohol and smoking was the commonest seen in 11 cases, followed by hypertension and obesity in 8 cases and alcohol with obesity in 2 cases. Change in lifestyle and eating habits may thus help reduce the incidence of stroke.

A study on clinical profile of stroke in young and elderly in GMERS Medical College and Hospital, Gandhinagar, Gujarat

“…This was also seen in study done by Jose´ Luis et al, 31 in which the most common locations of ICHs were lobar in (55%), second most common site was thalamoganglionic and ventricular with 2 cases, which was shown in book Neuroimaging -Methods, 33 in which most common site of hemorrhage was lobar followed by thalamoganglionic. In group-2 most common site of hemorrhage was thalamoganglionic (77%) followed by lobar (35%), similar trend was seen in study done by P. K. Chhetri et al 34 and Pipat Chiewvit et al 35 .…”

Computed tomographic pattern of stroke among adult patients in north-eastern Nigeria

“…This study also observed that the most common vascular territory involved is MCA territory seen in 69 patients (62.2%) while the least is the ACA territory (0.9%). This is similar to the report of a study conducted by Chhetri et al 15 who reported a 75% involvement of the MCA and 10% of ACA. The preponderant involvement of the MCA is probably because the MCA is the largest cerebral vessel and the one in direct continuity with the internal carotid artery thus prone to direct transmission of thrombus.…”

“…1 Adeyekun et al 14 reported the incidence of ischaemic stroke as 73.8% of all patients with stroke in Nigerians. In the same vain, higher incidence of ischaemic stroke was found in studies conducted by Chhetri et al 15 in Asia and Kehinde et al 16 in Nigeria.…”

Overview of The Head CT-Scan in Stroke Patients who was Treated at Muhammadiyah Hospital Palembang

“…Lacunar infarction is a deep subcortical infarction that usually involves the perforation of an artery in the deep gray matter and brainstem. Lacunar infarcts are usually less than 1 cm in dimensions and not more than 1.5 cm in diameter (21). The majority of lacunar infarcts are located in the area of the lenticular branches as well as the deep perforator medullary branches of the anterior, the branches thalamoperforating, thalamogeniculate, and middle cerebral arteries of the cerebral arteries, and the paramedian branches of the basilar arteries (18).…”

“…Thirty-three patients (91.66%) faced primary intracranial hemorrhage. The most frequently affected areas were the basal ganglia and the internal capsule (66.66%), followed by the thalamus (21.21%), the temporoparietal lobe (9.09%), and the posterior fossa (3.03%) (21). Supratentorial ICH is divided into lobar ICH (the center of the bleeding zone is in the white-gray matter junction) and deep ICH (the center of the bleeding zone in the basal ganglia and thalamus).…”
