The objective of this study was to define the perioperative risk of simultaneous operations in patients with abdominal aortic aneurysm (AAA) associated with coronary artery disease (CAD). The hospital data of 30 patients with coexistent severe symptomatic AAA and significant CAD, who underwent one stage surgery of the abdominal aorta and the coronary(More)
We describe a case of a patient with moderate hemophilia B, undergoing CABG. Substitution therapy was realized with factor IX concentrate (Bebulin-TIM4-IMMUNO). We discuss which of the following factors: hypothermia, hemodilution of heparinisation has a substantial role in alteration of FIX coagulant activity during cardiopulmonary bypass.
OBJECTIVES During unilateral selective cerebral perfusion (uSCP), with right axillary artery or brachiocephalic trunk cannulation, the brain receives blood only via the right common carotid artery and right vertebral artery (VA). The left hemisphere is perfused mainly through the circle of Willis (CW). However, at least 50% of individuals have some(More)
OBJECTIVES The optimal surgical technique for correction of left ventricular aneurysms is still debated. This study compares the midterm results achieved with linear resection or endoventricular repair. METHODS In the period February 2002-February 2004 forty-five consecutive patients with anterior LVA have been operated. The patients were divided in two(More)
We conducted a case–control study to determine the contribution of polymorphisms in CYP2C8 (CYP2C8*3) and CYP2J2 (CYP2J2*7) to increased risk of coronary artery disease and essential hypertension in Bulgarians. The current analysis included 192 unrelated hypertensive patients, 261 patients with angiographically documented CAD (153 with myocardial infarction(More)
Multifocal manifestation of atherosclerosis (ATS) is common for this pathology and demands special diagnostic and therapeutic approaches. The need of active screening of basic clinical forms of multifocal ATS--carotid, peripheral arterial disease (PAD), aortic abdominal aneurysms(AAA) and coronary (IHD) is mandatory along with precise indications of(More)
Extracranial carotid artery aneurysms are unusually rare. Their aetiology and clinical picture have significant meaning for their recognition, with the majority involving the common carotid artery--ACC. Approximately one third of these lesions are confined to the ICA, with an equal distribution between the proximal, middle, and distal segments. Nonoperated(More)
Recently, percutaneous transluminal angioplasty (PTA) with stent placement has gained greater acceptance for the treatment of hemodynamically significant atherosclerotic lesions involving the brachiocephalic, subclavian and vertebral vessels. PTA is performed instead of extratoracic bypass surgery, which is associated with several risks and complications.(More)
UNLABELLED Mitral valve repair (MVR) for mitral regurgitation (MR) has many advantages over mitral valve replacement. However, durability and reoperations after repair still remain major problems. The aim of our study was to analyze the outcome of MVR and to determine the significant risk factors for death and reoperations. METHODS From June 1989 to June(More)
The rupture of the sinus of Valsalva is a rare heart disease with a heavy clinical manifestation, the treatment of which is surgical. It is diagnosed with echocardiography and cardiac catheterisation. The anesthesiologist has to answer many and important questions about anesthetic treatment. There is a little information is the literature on the anesthetic(More)
