Background: Carotid endarterectomy in regional anesthesia is often associated with increased perioperative stress. We assumed that carotid endarterectomy performed under awake sedation with propofol is more beneficial to prevent such stress than alprazolam premedication only.

Methods: A total of 47 consecutive patients with significant carotid artery stenosis were enrolled into this investigation and followed up for 5 years to explore vascular complications.

Aims: Prosthetic graft infection frequently requires graft replacement. Among other options, a biological graft could serve as an alternative choice. Decellularization reduces tissue immunogenicity.

Background: Patients having coronary artery disease treated by coronary bypass or PCI procedure are exposed to tissue damage because of the phenomenon called reperfusion injury. Reperfusion injury can be characterized/monitored by oxidative stress parameters, inflammatory markers and by post-operative complication rate.

Objective: Beyond the obvious factors determining its severity (affected myocardial mass, ischaemic time, collateral circulation etc.

Aims: We studied the new anti-inflammatory effects of non-specific phosphodiesterase (PDE) inhibitor pentoxifylline (PTX) on ischaemia-reperfusion injury and postconditioning of the lower extremities. We aimed to examine the oxidative stress parameters (OSP), the inflammatory response and the changes in structure of skeletal muscle after revascularization surgery.

Methods: 50 Wistar rats in five groups underwent a 60 min infrarenal aortic cross clamping.

Introduction: Cerebral hyperperfusion syndrome is a rare, hardly known condition, which can result in serious complications either after surgical or endovascular revascularization. Recognition of the typical triad (headache, seizure, focal neurological deficit) and the prompt radiological diagnosis (sonography, computed tomography) are crucial to achieve a favourable outcome.

Aim: The aim of the authors was to select the endangered group and set up an effective therapeutic protocol based their own experience in combination with relevant literature data.

Aims: We studied the effects of the inhibition of the endogene antioxidant glutathione-S-transferase (GST) by ethacrynic acid (EA) on ischemia-reperfusion (IR) injury and postconditioning (PC) in the lower extremities. We aimed to examine the oxidative stress parameters (OSP), inflammatory response and activation of proapoptotic signaling proteins (PSP) after revascularization surgery.

Methods: Sixty Wistar rats were divided into 6 groups: control, IR, PC, EA-control, IR and administration of EA (IR/EA) and PC and administration of EA (PC/EA).

Introduction: In the pelvic region thrombendarterectomy and bypass procedures are the most commonly performed procedures to treat peripheral artery occlusive diseases with chronic, severe circulation failure caused by atherosclerosis. Biologic and synthetic grafts can also be used in bypass surgeries. Application of synthetic grafts can acutely increase the development of the infectious graft complication and its mortality is still between 70 and 75% in pelvic processes.

Case Report: In this article we present a relatively rare vascular surgical complication and an uncommon treatment of it. In this case we used an aorto-bifemoral bypass on a patient with Leriche syndrome. The implanted Y-graft got infected and we were forced to remove it.

Background: The indication for the surgical treatment of lower limb compartment syndrome mostly depends on the clinical signs, which can be uncertain and often delayed, resulting in a late and insufficient intervention.

Aim: In this study, the progression of compartment syndrome was monitored with the measurement of intracompartmental pressure and tissue oxygen saturation.

Materials And Methods: 16 patients (12 male and 4 female; mean age: 62,7 years) underwent acute lower limb revascularization surgery due to critical (more than 4 hour) limb ischaemia.

The authors aimed to study of oxidative stress and thrombocyte function in the perioperative interval following the revascularization surgery of lower limb. The prospective randomised study involved 10 patients whose surgical interventions were indicated by lower limb embolism, thrombosis or abdominal aorta aneurysm, and 10 healthy volunteers were also involved in the study. Peripheral blood samples were collected before, and after the surgery (2, 24 hours and one week).
