Results of 351 intravenous digital subtraction angiographs (AN) of transplanted kidneys emphasized reliability of this examination for detection of renal artery stenosis. A prospective study of 219 patients (188 interpretable AN) showed significant stenosis of grafted artery in 22% of cases: 17% of the 126 patients with normal blood pressure and 34% of the 62 cases of hypertension. Digital subtraction allows, with a single injection, assessment of renal artery, nephrogram and excretory cavities, but it is not a substitute for conventional intravenous urography 1 to 2 months after grafting.

Purpose: Anatomical variations in the anterior choroidal artery (AChA) and/or the posterior cerebral artery (PCA) are rare. Hyperplastic AChA is an anatomical variant supplying both the AChA area and the PCA area. In accessory PCA, a hyperplastic AChA supplies part of the PCA territory.

Acute ischemic stroke, a medical emergency caused by reduced cerebral blood flow, results in brain cell damage. While commonly associated with older individuals, strokes can also occur in young and middle-aged adults, posing significant socio-economic and health challenges due to the long-term impact of the condition. This poses significant socio-economic and health challenges because stroke is a leading cause of disability and mortality.

Background: Amphetamines possess sympathomimetic properties that can affect cerebral vasculature though conflicting reports exist about their effect on vasospasm risk and clinical outcomes in aneurysmal subarachnoid hemorrhage. This study aimed to characterize the impact of recent amphetamine use on vasospasm development in aneurysmal subarachnoid hemorrhage as well as neurological outcomes.
Methods: We retrospectively screened 441 consecutive patients admitted with a diagnosis of subarachnoid hemorrhage who underwent at least one cerebral digital subtraction angiogram.

Objective: To develop a machine learning-based model for predicting the clinical efficacy of acupuncture intervention in patients with upper limb dysfunction following ischemic stroke, and to assess its potential role in guiding clinical practice.
Methods: Data from 1,375 ischemic stroke patients with upper limb dysfunction were collected from two hospitals, including medical records and Digital Subtraction Angiography (DSA) reports. All patients received standardized acupuncture treatment.

Objective: Recent studies suggested that the medical control of atherogenic lipoproteins is not sufficient for stroke prevention. A low apolipoprotein A-I (apoA-I) level may play a crucial role in the anti-atherogenic effects of high-density lipoprotein (HDL-C) and may also be associated with symptomatic vulnerable plaques in carotid artery stenosis. Therefore, the present study investigated the relationship between apoA-I levels and the status of carotid artery stenosis.
