Objective: This study was conducted to identify the diagnostic value of carotid stump pressure for determining the need for a carotid artery shunt in patients undergoing carotid artery endarterectomy.

Materials And Methods: Carotid stump pressure was prospectively measured in all carotid artery endarterectomies performed under local anesthesia between January 2020 and April 2022. The shunt was selectively used when neurological symptoms appeared after carotid cross-clamping.

Background: It is critical to clarify the biochemical factors associated with thrombosis development following tunneled dialysis catheter (TDC) insertion.

Methods: The study involved retrospective analysis of charts of patients hospitalized for permanent TDC placement between 2013 and 2020 in a tertiary academic center. Patients undergoing a hemodialysis schedule with permanent TDC for more than three months were included in the study.

Chaetomium globosum is a dematiaceous, filamentous fungus belonging to the large genus saprobic ascomycetes and is rarely involved in human infection. We present the case of a 25-year-old man undergoing tricuspid valve replacement due to recurrent prosthetic ring endocarditis. Initially, it was considered culture-negative endocarditis; however, the diagnosis of Chaetomium globosum could only be provided by DNA isolation of the mold isolate grown in culture and the valve tissue samples taken from the patient.

Background: We aim to compare the diameters of ascending aorta in COVID-19 patients and COVID-19-free individuals referred to our pandemic hospital.

Methods: The medical records and thorax tomographies of patients admitted to the "pandemic central" state hospital with symptoms of COVID-19 were observed between April 2020 and May 2020 in this case-control study. The first group consisted of patients diagnosed with COVID-19, and the second group consisted of patients without the disease.

Background: In the present retrospective, single-center study, we evaluated the long-term effectiveness and reliability of endovenous laser ablation (EVLA), endovenous n-butyl cyanoacrylate (NBCA) application, and radiofrequency ablation (RFA) in the management of chronic venous insufficiency (CVI).

Methods: The medical records of patients who had undergone EVLA, NBCA, or RFA for CVI from January 1, 2014 to January 1, 2017 were reviewed. The medical records included data on sex, age, body mass index, American Society of Anesthesiologists score, and symptoms at admission.

Unlabelled: Kidney anomalies are always a challenge even for the most experienced vascular and urologic surgeons in the reconstruction of the abdominal aortic segment. In the literature, the most common anomalies of the kidney are the horseshoe kidney.

The Case: A 77-year-old male headed to the emergency department with complaints of acute abdominal pain and sudden onset of fatigue.

Infrarenal abdominal aortic aneurysm with aortocaval fistula, a rare condition, can be fatal without prompt intervention. The clinical symptoms are complex and varied, so diagnosis is typically confirmed by use of contrast-enhanced multidetector computed tomography. We report our surgical repair of a 13-cm-diameter infrarenal abdominal aortic aneurysm and aortocaval fistula in a 63-year-old orchestral tuba player who had 2 classic symptoms of the condition.

Objective: The endovenous application of n-butyl cyanoacrylate (NBCA) is a new nontumescent ablation technique for the treatment of venous insufficiency. The aim of this study was to retrospectively compare an NBCA-based ablation method with endovenous laser ablation (EVLA) for the management of incompetent great saphenous veins.

Methods: Between May 2013 and August 2014, there were 339 patients with incompetent varicose veins who were treated with either the endovenous application of NBCA (VariClose Vein Sealing System [VVSS]; Biolas, Ankara, Turkey) or EVLA.

Background: The aims of this preliminary study were to determine the alteration of serum ischemia-modified albumin (IMA) levels and to investigate whether IMA may be used as an indicator of the cardioprotective efficacy of N-acetylcysteine (NAC) in patients undergoing coronary bypass grafting (CABG).

Patients And Methods: Forty-four patients were randomized into one of two groups on the basis of cardioplegic strategies, either cold-blood cardioplegia enriched with NAC (50 mg/kg) or cold-blood cardioplegia alone. Serum IMA, cardiac troponin T (cTnT) and malondialdehyde (MDA) levels determined in NAC-enriched patients before and after CABG were compared with those of the NAC-free group.

Ovari an vein thrombosis (OVT) is an uncommon, life-threatening complication of pregnancy. OVT clinical presentation is similar to that of acute appendicitis, and the latter is therefore the suspected diagnosis in most cases. We describe a case of a 36-year-old woman experiencing deep vein thrombosis and pulmonary embolism during the course of pregnancy and presenting to the emergency department with sudden pain in the right lower quadrant and severe abdominal pain.

Objective: The internal thoracic artery is frequently used as an arterial graft for coronary bypass. Spasms of internal thoracic artery may contribute to early myocardial ischemia. To prevent vasospasm and increase the blood flow, some vasodilatory agents (such as carbon dioxide or papaverine) are used.

Background And Introduction: It has been suggested that chronic infections may have a role in both the initiation and progression of atherosclerosis. While the majority of available data are focused on coronary artery disease, our aim was to investigate the presence of Chlamydia pneumoniae and Helicobacter pylori in samples from aortoiliac occlusive disease.

Methods: Aorta-iliac atherectomy specimens were collected under sterile conditions from 21 patients (19 male, 2 female) undergoing surgery for aortoiliac occlusive disease.

Background: Cold-blood cardioplegia is a well-known method in coronary artery bypass graft surgery, and several authors have used various agents in the enrichment of cold-blood cardioplegia to decrease ischemia-reperfusion injury seen during surgery. N-acetylcysteine, which can increase glutathione levels, is one of the agents added to cardioplegic solutions to decrease myocardial injury. This study was planned to assess the efficiency of N-acetylcysteine-enriched cold-blood cardioplegia on early reperfusion injury in patients with ischemic heart disease undergoing coronary artery bypass grafting, using measurements of cardiac troponin I and malondialdehyde release.

Perioperative spasm of internal mammary artery is a common experience in coronary artery bypass grafting. Many techniques were described of harvesting the internal mammary artery to prevent vasospasm. We investigated the comparison of the contracting and relaxing responses of human internal mammary artery grafts harvested by two different methods.

Objective: The purpose of this study was to investigate the potential use of low-tube-current MDCT virtual bronchoscopy for the evaluation of children with suspected foreign body aspiration.

Subjects And Methods: Low-tube-current MDCT was performed in 23 patients (10 girls, 13 boys) with a mean age of 3.3 years (9 months-13 years) with suspicion of foreign body aspiration.

Background: This study was conceived to evaluate the effect of carbon dioxide insufflation on free internal thoracic artery flows.

Methods: We studied 56 consecutive patients who underwent coronary artery bypass grafting in which the left internal thoracic artery was anastomosed to the left anterior descending artery. The first 26 consecutive internal thoracic arteries were harvested as a pedicled graft (group 1), and the next 30 consecutive internal thoracic arteries were dissected by using the carbon dioxide insufflation technique (group 2).
