Analysis of the correlations between the extracranial internal carotid artery and extracranial vertebral artery and mild cognitive impairment.

Background: Vascular tortuosity is a prevalent morphological change that frequently occurs in arteries across different parts of the body.

Objective: To analyze the relationship between the tortuosities of the extracranial internal carotid artery (EICA) and extracranial vertebral artery (EVA) with mild cognitive impairment.

Methods: The tortuosity index (TI), vascular deviation degree, tortuosity degree, and angle number of the EICA and EVA were retrospectively analyzed and calculated in 160 patients who underwent computed tomography angiography (CTA) in this study's department, and the Montreal cognitive assessment was adopted to evaluate the cognitive function of the patients.

Multidisciplinary treatment of a patient with necrotizing fasciitis caused by : A case report.

Because of high morbidity and mortality, accurate diagnosis and early treatment with adequate antibiotics and surgical intervention are vital. And timely identification and treatment of complications are necessary to improve survival of patient.
