Drug Coated Balloon Angioplasty in Failing AV Fistulas: A Randomized Controlled Trial.

American Society of Nephrology. Clinical Journal, 2018
BACKGROUND Restenosis remains a problem in hemodialysis access interventions. Paclitaxel-coated balloons have shown promise in reducing access-related restenosis in small trials.

Time Delay to Treatment and Mortality in Primary Angioplasty for Acute Myocardial Infarction: Every Minute of Delay Counts

Circulation, 2004
Background—Although the relationship between mortality and time delay to treatment has been demonstrated in patients with acute ST-segment elevation myocardial infarction (STEMI) treated by thrombolysis, the impact of time delay on prognosis in patients ...

Improvement of the splanchnic blood flow and hepatic vein oxygenation following revascularization in patients with chronic mesenteric ischaemia

Clinical Physiology and Functional Imaging, Volume 43, Issue 1, Page 33-39, January 2023., 2023
Abstract Objectives Chronic mesenteric ischaemia (CMI) is an underdiagnosed but severe condition. Access to functional testing is often limited and the diagnosis is usually based primarily on symptoms and imaging. One of the functional tests available is measurement of the splanchnic blood flow (SBF).

Acute myocardial infarction in progressively elderly patients. A comparative analysis of immediate results in patients who underwent primary percutaneous coronary intervention

Arquivos Brasileiros de Cardiologia, 2001
OBJECTIVE: Analysis of the in-hospital results, in progressively elderly patients who undergo primary percutaneous coronary intervention (PCI) in the first 24 hours of AMI. METHODS: The patients were divided into three different age groups (60/69, 70/79,

Usage of excimer laser in coronary and peripheral artery stenosis – analysis of its safety aspect

Journal of Pre-Clinical and Clinical Research, 2020
Introduction The technology of laser atherectomy has been known for about 20 years. Initial studies were not encouraging due to similar or lower efficacy compared to conventional angioplasty and greater complication rate.

A Comparison of Immediate Angioplasty with Thrombolytic Therapy for Acute Myocardial Infarction

, 1993
Background The success of thrombolytic therapy for acute myocardial infarction is limited by bleeding complications, the impossibility of reperfusing all occluded coronary arteries, recurrent myocardial ischemia, and the relatively small number of ...

Robust Landmark-based Stent Tracking in X-ray Fluoroscopy [PDF]

arXiv, 2022
In clinical procedures of angioplasty (i.e., open clogged coronary arteries), devices such as balloons and stents need to be placed and expanded in arteries under the guidance of X-ray fluoroscopy. Due to the limitation of X-ray dose, the resulting images are often noisy.
