Objective: To evaluate the influence of Bentall procedure on left ventricular function and condition on long-term follow-up.

Methods: Seventy-three consecutive patients who underwent an aortic root and ascending aorta replacement with composite valve button Bentall or flanged Bentall technique, from January 2007 to November 2018, were included in this retrospective study.

Results: Postoperative left ventricular ejection fraction significantly increased (52.

Introduction: The carotid endarterectomy is already well established in patients with symptomatic or asymptomatic internal carotid artery (ICA) stenosis. The aim of this study was to determine whether there is a difference in postoperative blood pressure changes, stroke rate and postoperative complications following eversion carotid endarterectomy (E-CEA) and conventional carotid endarterectomy (C-CEA).

Methods: From 1 January 2010 to 31 March 2017 consecutive patients admitted to our department with symptomatic or asymptomatic ICA stenosis were included in this retrospective study.

Pancreaticoduodenal artery aneurysms (PDAAs) are rarely seen among the visceral artery aneurysms (<2%). PDAA is mostly asymptomatic but can be presented with abdominal pain. Embolization can be applied safely with a high success rate; however, in some conditions such as when embolization fails or accompanying celiac axis occlusion, open surgery can be performed.

Posterior nutcracker syndrome is caused by the compression of left renal vein between the abdominal aorta and the vertebral body. Most seen symptoms are haematuria, left flank pain, abdominal pain and varicocele. The nutcracker syndrome may lead to left renal vein thrombosis due to blood congestion within compression of the vessel.

A paraganglioma is a rare tumor that develops out of extra-adrenal chromaffin cells and pheochromocytomas originating from the adrenal medulla. Early diagnosis and surgical planning are crucial, since the tumor secretes catecholamine and is adjacent to large vessels in the abdomen. Furthermore, since complete resection improves the prognosis, we recommend a meticulous surgical technique.

In this study, we present a 55-year-old female patient who suffered from atrial septal defect (ASD) and retrosternal toxic goitre simultaneously. The patient had been treated with a 300 mg/day dose of propylthiouracil for 20 days prior to operation. This patient has been operated on for both disorders and has recovered.

In this study, we examined the adherence of slime-producing standard Staphylococcus epidermidis strain ATCC 12228 to Dacron and polytetrafluoroethylene (PTFE) grafts in in vitro medium either containing salicylate or not. Dacron and PTFE graft pieces of standard size were placed in trypticase soy broth either containing 5 mM acetylsalicylic acid solution or not. These soy broths also contained 1 x 10(7) colony-forming units/mL S.
