[Introduction of the microwave thermoablation (MWA) method to hemorrhoid surgery].

Abstract: In addition to the traditional surgical options for hemorrhoid disease, newer treatment methods are evolving along the principle of reducing the burden on patients and providing similar or better healing. Thermo-based systems achieve the desired effect with less physical destruction. In this paper, we discuss the results of hemorrhoid surgery performed with laser and microwave devices.

[Cerebral hyperperfusion syndrome and blood pressure control].

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.

[Dilemmas of the reconstruction of the major pelvic artery due to infectious aortic graft complication].

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.
