Renal Artery Partial Occlusion After Aortic Dissection Is Associated With Impaired Renal Function in the Affected Kidney.

Background: The renal artery is often involved in aortic dissection, leading to kidney ischaemia and renal dysfunction. However, some patients with aortic dissection with combined renal artery involvement do not show clinical renal dysfunction. This study aimed to analyse the relationship between renal artery involvement and renal function.

Treating patients with abdominal aortic aneurysm with endovascular repair and the crossover chimney technique in the internal iliac artery to protect the unilateral internal iliac artery.

This study aims to explore the treatment methods for patients with abdominal aortic aneurysms (AAAs) that required occlusion of the openings of the bilateral internal iliac arteries (IIAs) in endovascular aneurysm repair (EVAR) and to evaluate the efficacy of these treatments. Four patients with AAA were treated with endovascular aneurysm repair (EVAR) and the crossover chimney technique in the bilateral internal iliac arteries (IIAs). We inserted and released the abdominal aortic stent as usual and implanted the bypass stent graft simultaneously.

Endovascular Repair for Thoracic Aortic False Aneurysms: Single-Center Experience in 102 Patients.

Background: Thoracic aortic false aneurysm is unusual and experience with endovascular repair is limited. We evaluate the efficacy of endovascular repair in patients with thoracic aortic false aneurysms.

Methods: The early and midterm outcomes of endovascular repair in 102 patients with thoracic aortic false aneurysms were analyzed.

Computed tomography perfusion source images assessment of infarct core and penumbra in acute stroke.

Objective: The purpose of this study was to develop a methodology on computed tomography (CT) perfusion source images for an acute ischemic stroke in predicting infarct core and penumbra.

Methods: Computed tomography examinations, including non-contrast enhanced CT, CT perfusion and CT angiography, were performed on 24 patients with symptoms of stroke in less than 9 hours. The Alberta Stroke Program Early CT Score (ASPECTS) was analysed on arterial and venous phase CT perfusion source images and then compared with the ASPECTS on follow-up imaging for an efficacy assessment.

Brain magnetic resonance elastography on healthy volunteers: a safety study.

Background: Magnetic resonance elastography (MRE) is a recently developed imaging technique that can directly visualize and quantitatively measure tissue elasticity.

Purpose: To evaluate the safety of brain MRE on human subjects.

Material And Methods: The study included 20 healthy volunteers.
