Compensating for Angiographic Underestimation With Oversized Balloon Angioplasty in Patients With Chronic Limb-Threatening Ischemia and Occluded Below-the-Knee Vessels.

Purpose: Our study aims to determine optimal sizing of below-the-knee (BTK) artery angioplasty without intravascular ultrasound (IVUS), compensating for conventional angiography underestimation by selecting a balloon size one size larger than the 1-to-1 angiographic sizing.

Materials And Methods: Our study is a retrospective, single-center study. Patients were separated into 2 groups as over and angiographic reference group which the over group is larger balloon diameter selection (0.

Ischemia-modified albumin use as a prognostic factor in coronary bypass surgery.

Background: Various types of markers have been used so far in order to reveal myocardial perfusion defect. However, these markers usually appear in the necrosis phase or in the late stage. Having been the focus of various investigations recently, ischemia-modified albumin (IMA) is helpful in establishing diagnosis in the early stages of ischemia, before necrosis develops.
