However, its use has been controversial due to many types of the PRP definition, optimal concentration, and modalities of implementation.

[Open versus percutaneous repair of abdominal aortic aneurysm].

Background: The mortality in aortic abdominal aneurysm surgery remains in the 2-7% range. The aim of the study was to compare the results and safety of surgical aneurysm resection with grafting under general anaesthesia, using percutaneous insertion of a stent under local anaesthesia and intravenous analgesic sedation.

Methods: The data from patients scheduled for elective subrenal abdominal aortic treatment was analysed retrospectively.

[Effectiveness and safety of unilateral spinal anaesthesia].

Background: The purpose of the study was to evaluate the effectiveness and safety of unilateral spinal anaesthesia and to compare this technique to the commonly used bilateral technique in a prospective, controlled, randomized study.

Methods: Fifty-four ASA I-III adult patients, of both sexes, aged 18-75 years, and scheduled for elective unilateral surgery, were randomly allocated into two groups: a unilateral spinal anaesthesia group (group B, n=27, to receive 0.5% hyperbaric bupivacaine, 1.
