Background: This study aims to investigate alternative vascular access methods in patients in whom conventional hemodialysis methods fail. Methods: Between January 2007 and March 2011, a total of 15 patients (6 males, 9 females; mean age 40 years; range 28 to 78 years) who were diagnosed with superior and inferior vena cava occlusion and underwent...

Introduction: The aim of this study was to investigate the effects of Adducin Gly460Trp, and methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C gene polymorphisms that are supposed to play a role in atherothrombotic process in patients with peripheral arterial disease (PAD). Materials and methods: This prospective study was performed on a...

The Nd:YAG laser has been considered the gold standard of treatment for leg veins, but pain and side effects have fueled physicians to use treatment alternatives. To compare the clinical efficacy of the long-pulsed 1064-nm Nd:YAG laser with KTP laser irradiation in the treatment of leg telangiectasia. A series of 16 patients with size-matched super...

Small number of patients with chronic pulmonary hypertension have surgical treatment alternative. Secondary pulmonary hypertension due to left heart diseases forms one of the groups that can be surgically treated as well as the chronic thromboembolic pulmonary hypertension (CTEPH) patients. A 58-year old female patient, who had been under medical t...

Peripheral arterial aneurysms (PAA) may rupture, cause emboli and ischemia, and local symptoms due to compression. A total of 109 patients who underwent surgery for PAA were analyzed retrospectively, including clinical presentation, surgical procedures used, and postoperative follow-up data obtained 10 days after discharge. True aneurysm was presen...

Intimal hyperplasia is a major cause of restenosis after the interventional or surgical treatment of occlusive arterial disease. We investigated the effects of clopidogrel, calcium dobesilate, nebivolol, and atorvastatin on the development of intimal hyperplasia in rabbits after carotid venous bypass surgery. We divided 40 male New Zealand rabbits...

Moraxella catarrhalis is a gram-negative, catalase and oxidase positive diplococcus. While it causes otitis media, sinusitis, bronchitis and conjunctivitis in children and adults, it has a tendency to cause lower respiratory tract infections in older ages. More severe clinical pictures with the range of sepsis to endocarditis are also seen in immun...

Penetrating cardiac injuries have a rather high mortality and require a rapid diagnosis and emergency surgical intervention. The aim of this study was to present and discuss our experience with penetrating heart wounds. Sixteen patients with penetrating cardiac injury underwent surgical treatment at the Department of Cardiovascular Surgery between...

The term "competitive flow" defines the flow from a partially stenosed native artery that "competes" with the flow from a graft to perfuse the distal tissues. The purpose of our study is to investigate the effects of competitive flow at different degrees of stenosis at common carotid artery, in a rabbit model by measuring both the flow volume and v...

Percutaneous interventions are increasingly used in the treatment of cardiac diseases which are resistant to medical treatment. However, the complications caused by these interventions can lead to serious results. In this article, we present a case of a successful combination of interventional and surgical treatment methods, following the developme...

We report a patient with pulmonary embolism, dissection in the descending and abdominal aorta, and persistent left superior vena cava. To our knowledge, coexistence of these three clinical entities has never been described before in the same patient.

Upper extremity peripheral artery aneurysms are a rarely encountered arterial disorder. Brachial artery aneurysms seen in the pediatric age group are generally trauma resultant. A nine-month-old male infant patient presented with complaints of an asymptomatic mass in the arm. Following Doppler ultrasonography and magnetic resonance imaging (MRI) ex...

The aim of this prospective study was to evaluate the relationship between preoperative circadian blood pressure pattern and early postoperative course in patients undergoing coronary artery bypass graft (CABG) surgery. One hundred and thirty patients planning to undergo isolated CABG operation were included to the study (80 men; 50 women). All pat...

Placement of an external support has been reported to prevent intimal hyperplasia of vein grafts. In this study, we investigated the effect of HA/CMC on intimal hyperplasia in a rabbit model. Right jugular vein to common carotid artery bypass grafting was performed in 24 female New Zealand white rabbits (2.5-3.0 kg). Animals were divided into two g...

An increasing number of patients are found to be unsuitable for revascularization by conventional approaches to the epicardial vessels. Transmyocardial laser revascularization (TMR) is a treatment choice for patients who have refractory angina pectoris when bypass surgery or percutaneous transluminal angioplasty is not indicated. Transmyocardial la...

Deep vein thrombosis (DVT) often begins in the calf veins or around the venous valves in the solar plexus in the lower extremities. Thrombus formation does not organize before 5–10 days and the risk of proximal progress and pulmonary thromboembolus (PTE) is high in an unorganized thrombus [1]. PTE develops in about 20% of untreated proximal venous...

This study compared the effects of different methods of papaverine application on free blood flow and harvesting time of the internal thoracic artery for coronary bypass grafting. Patients were randomly divided into 3 groups of 25 each: group 1 had papaverine injected into the endothoracic tissue around the internal thoracic artery before dissectio...

Acute aortic dissection is an uncommon disease; however, it has a high mortality rate. Classically, aortic dissection presents with sudden and severe pain in the chest, back, or abdomen. Patients often describe tearing or ripping pain. There are a few reports of atypical findings or no pain in the literature. We report a case of painless, acute aor...

Myocardial bridging is one of the nonatherosclerotic causes of coronary artery disease and is characterized by muscles overlying the intramyocardial course of a major epicardial coronary artery segment, leading to systolic compression. Myocardial bridging is considered a benign condition in most cases, but has been associated with serious cardiac e...

Chylothorax is potentially serious complication of pediatric cardiac operations and its treatment is often difficult. We report a case of 11 years old male who underwent aortic coarctation repair. A persistant chylothorax developed during early postoperative period. The attempts of classic conservative alternative treatments such as total parentera...

We are providing here a retrospective evaluation of vascular injuries occuring due to iatrogenic reasons and the surgical operations performed in the treatment. Surgical operations were performed on 52 cases with iatrogenic vascular injuries between 1984-2004 at our cardiovascular surgery clinic. The patients included 33 males and 19 females, with...

Venous thrombosis is a multifactorial disease, that genetic and environmental factors play a part. Especially, in the patients who have experienced recurrent venous thromboembolisms (VTE) and also in their relatives with similar clinical features; it might present as a congenital coagulation inhibitor deficiency that can cause hereditary thrombotic...

Retrosternal epicardial adhesions may cause significant injuries to the heart and great vessels in cases that require reoperation. We used a varity of agents to prevent the occurence of adhesions and observed different results. An experiment with 3 groups of rabbits with 10 rabbits in each group was prepared to investigate the roles of Dexamethazon...

Objective: The aim of this prospective study was to evaluate the relationship between preoperative circadian blood pressure pattern and early postoperative course in patients undergoing coronary artery bypass graft (CABG) surgery. Methods: One hundred and thirty patients planning to undergo isolated CABG operation were included to the study (80 men...
