Purpose: Blood transfusion; is considered an organ transplant. In coronary bypass surgery, large volumes of homologous blood transfusion may be required due to excessive bleeding. The large number of use of homologous blood transfusion in open heart surgery and the awareness of its various harmful effects have prompted researchers to conduct research on the use of autologous blood.

Objectives: The present study aimed to compare the effects of medical therapy (MT), systemic thrombolysis (ST), and pharmacomechanical thrombolysis (PMT) methods used in our clinic for the treatment of deep venous thrombosis (DVT) on symptom reduction, the incidence of post-thrombotic syndrome (PTS) development, and quality of life.

Methods: Data from160 patients diagnosed with acute DVT between January 2012 and May 2021 and treated and followed up in our clinic were retrospectively analyzed. The patients were divided into three groups according to treatment method.

Introduction: Our study aimed to examine the impacts of blood cardioplegia (BC) and del Nido cardioplegia (DNC) solutions - which we used in isolated coronary artery bypass grafting (CABG) - on early mortality and major adverse events (MAE).

Methods: We retrospectively analyzed 329 consecutive patients who underwent CABG in our clinic between January 2016 and January 2020. Myocardial infarction, reoperation, cardiac tamponade, stroke, renal failure, extracorporeal membrane oxygenation requirement, and cardiopulmonary resuscitation were defined as MAE.

Background: Varices and venous insufficiency are common and serious health problems in the general population which affect the quality of life. Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux, and the endovenous laser ablation (EVLA) method has been widely accepted all over the world. In this method, ablation is provided by a laser fiber inserted into the lumen of the vein.

Background: The primary objective of this multicentre prospective observational study was to evaluate the early results of a new non-thermal embolisation method using N-butyl cyanoacrylate in venous insufficiency.

Patients And Methods: A total of 181 patients with a varicose vein diagnosis were treated with the VariClose: Vein Sealing Systems at four different centres. The protocol included physical and colour Doppler ultrasonography examination, venous clinical severity score and quality of life assessment before and after the procedure on days 1 and 7 and at months 1, 3 and 6.

Background/aim: The objective of this study is to report our experience with surgical revision of dialysis access-induced ischemia syndrome.

Materials And Methods: Between January 2005 and July 2013, 1254 patients underwent arteriovenous fistula operation, and 86 of them [53 males, mean age: 55 ± 25 (range: 25 to 75) years; 33 females, mean age: 50 ± 20 (range: 30 to 70) years] subsequently developed steal syndrome. These patients were treated with arterial pressure-controlled polytetrafluoroethylene banding or constriction with polypropylene suturing technique.

Background: The purpose of this study was to evaluate the efficacy and safety of pharmacomechanical thrombectomy performed by using a rotational thrombectomy device for the treatment of deep vein thrombosis.

Methods: Between April 2012 and November 2014, 17 patients with acute deep vein thrombosis underwent pharmacomechanical thrombolysis. The thrombectomy device was used in a single-session technique for patients with lower-extremity deep vein thrombosis.

Chronic kidney failure can be described as a chronic and progressive disfunction in metabolic-endocrine function and in adjustment of fluid-electrolyte balance of kidney, as a result of reducing of glomerular filtration value. Besides being a medical issue, chronic kidney failure affects social, economic, and psychological conditions of patients. Indwelling catheters can be placed in the right atrium by right mini thoracotomy in kidney patients who depend on dialysis and all central veins are used.

Background: We sought to evaluate the effects of on-pump beating-heart versus conventional coronary artery bypass grafting techniques requiring cardioplegic arrest in patients with coronary artery disease with left ventricular dysfunction.

Methods: We report the early outcomes associated with survival, morbidity and improvement of left ventricular function in patients with low ejection fraction who underwent coronary artery bypass grafting between August 2009 and June 2012. Patients were separated into 2 groups: group I underwent conventional coronary artery bypass grafting and group II underwent an on-pump beating-heart technique without cardioplegic arrest.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade.

Objective: There are various reasons for renal dysfunction after cardiac surgery; however, activation of the renin-angiotensin system has an important role following cardiac surgery. We investigated the effect of preoperative angiotensin-converting enzyme (ACE) inhibitors on renal functions after cardiovascular surgery.

Material-methods: Three hundred sixty-six patients awaiting elective cardiac surgery were allocated to two groups, namely the treatment group, comprising the ACE inhibitor group (n = 186), and the control group, which was without ACE inhibitor (n = 180).
