Safety and functionality of transhepatic hemodialysis catheters in chronic hemodialysis patients.

Purpose: We aimed to investigate the safety and functionality of tunneled transhepatic hemodialysis catheters in chronic hemodialysis patients.

Methods: Thirty-eight patients (20 women aged 56±10 years and 18 men aged 61±11 years) with transhepatic tunneled hemodialysis catheters were evaluated. The date of the first transhepatic catheterization, indications, procedure details, functional time periods of catheters, reasons for the removal or revision of catheters, catheter-related complications, and current conditions of patients were retrospectively analyzed.

Off-pump bypass grafting in patients with significant left main coronary artery stenosis.

The aim of this study was to investigate and determine whether patients with significant (> or = %50) left main coronary artery stenosis could undergo coronary bypass on the beating heart and compare the results to those obtained using the conventional method. Prospectively collected data of patients with significant left main coronary artery disease who had undergone coronary bypass on the beating heart (group A, n = 100) or with the conventional method (group B, n = 100) were evaluated retrospectively. EuroSCORE values, preoperative and operative details, postoperative morbidity and mortality, and early results were compared.
