Procedure and Clinical Success of Drug-Coated Balloon Fistuloplasty of the Drainage Vein in Dysfunctional Native Arteriovenous Fistulas.

Purpose: Native arteriovenous fistulas (AVFs) are the most effective vascular access (VA) for haemodialysis. We aimed to evaluate the results of balloon angioplasty (fistuloplasty) from drainage vein performed for the treatment of AVF dysfunction in haemodialysis patients and examine potential patient and AVF-associated factors that might affect such results.

Methods: This is a nonrandomized, retrospective, and single-centred study.

Bacterial Load Associated With Tunneled Dialysis Catheters in Symptom-Free Hemodialysis Patients.

Objective: This study aimed to evaluate the rate of asymptomatic bacterial infection of tunneled dialysis catheters (TDCs) removed due to maturation of native arteriovenous fistula (nAVF) or catheter dysfunction in hemodialysis patients with no clinically apparent infection.

Materials And Methods: A total of 229 patients (43.2% [n = 99] female and 56.

Oxidative status and antioxidant enzyme levels in deep venous thrombosis patients.

Deep vein thrombosis (DVT), a subset of venous thromboembolism (VTE), is a major preventable cause of morbidity and mortality worldwide. We aim to investigate changes in oxidative injury markers and the levels of antioxidant parameters in DVT patients. 50 DVT patients who were admitted to the cardiovascular surgery clinic with acute (<2 weeks) or chronic (≥4 weeks) DVT and 100 healthy individuals were included.

The Factors Affecting Rhythm Control for Cryoablation of Atrial Fibrillation in Mitral Valve Surgery.

Objective: To evaluate the factors impacting on the conversion to sinus rhythm and on the postoperative rhythm findings in the six-month follow-up period of a mitral valve surgery combined with cryoablation Cox-Maze III procedure, in patients with atrial fibrillation.

Methods: In this study, we evaluated 80 patients who underwent structural valve disease surgery in combination with cryoablation. Indications for the surgical procedures were determined in the patients according to the presence of rheumatic or non-rheumatic structural disorders in the mitral valve as evaluated by echocardiography.

MnSOD, CAT and GPx-3 genetic polymorphisms in coronary artery disease.

In this study, we aimed to determine the gene polymorphisms of antioxidant enzymes that determine or affect antioxidant activity in the occurrence of the disease and/or complications during and after the surgery in patients who were decided to undergo coronary artery bypass surgery due to coronary artery disease. Blood samples taken before operation in 26 coronary artery patients who were decided to be operated according to the international procedure and the phenol/chloroform method was used to isolate DNA. DNA samples were amplified by using polymerase chain reaction (PCR) method with specific primers for MnSOD, CAT, GPx-3 antioxidant gene regions.

Change in Free Radical and Antioxidant Enzyme Levels in the Patients Undergoing Open Heart Surgery with Cardiopulmonary Bypass.

. The purpose of this study is to determine the changes in oxidative damage and antioxidant parameters in open heart surgeries with cardiopulmonary bypass (CPB) in preoperative and early postoperative periods. .

The Effect of On-Pump and Off-Pump Bypass Operations on Oxidative Damage and Antioxidant Parameters.

Objective: The aim of the study is to determine the oxidative status in on-pump and off-pump coronary artery surgery and contribute to possible surgical choices in clinical practices in accordance with the information obtained as a result of this study.

Methods: 52 patients undergoing open heart surgery (26 patients in on-pump group and 26 patients in off-pump group) were included in the study. MDA, GPx, GSH, CAT, and SOD were investigated in blood samples.
