Modern diagnostic approach to patients with abdominal aortic aneurysm.

Introduction: Abdominal aortic aneurysm (AAA) is a relatively frequent and serious condition in vascular surgery. The diagnostic and indication process and its treatment are driven by the guidelines which dictate an intervention when the maximum AAA diameter is more than 55 mm. Nevertheless, this approach is not fully sufficient in all AAA cases and thus we have been seeking to develop a modern diagnostic tool using computer modeling and vascular wall stress analysis.

Endovenous ablation of varicose veins current status and overview of methods.

During the last two decades, superficial venous surgery has experienced an unprecedented boom. Traditional surgical procedures (crossectomy and stripping) are now being replaced to a greater or lesser extent by new less invasive endovenous methods. Our aim is to provide an up-todate review of all available endovenous techniques (laser, radiofrequency, steam, mechanochemical ablation and venous glue) describing the indications, the technique and mechanism of action, and the results.

Procalcitonin kinetics following abdominal aortic surgery and its value for postoperative intestinal ischaemia detection.

Objective: The purpose of our study was to describe perioperative kinetics of procalcitonin (PCT) in patients undergoing aortic surgery, to compare the kinetics in the open abdominal aortic aneurysm (AAA) repair and aortobifemoral bypass for aortoiliac occlusive disease (AIOD), and to evaluate the ability of PCT to detect intestinal ischaemia.

Methods: A prospective non-randomized observational cohort study in 80 patients (62 men and 18 women) undergoing elective aortic surgery was performed. Serum PCT was measured at baseline and defined intraoperative and postoperative timepoints up to postoperative day 7.

l-lactate kinetics after abdominal aortic surgery and intestinal ischemia - An observational cohort study.

Background: Postoperative intestinal ischemia is a severe complication in abdominal aortic surgery. Early diagnosis is needed for adequate and timely treatment. We studied the postoperative kinetics of l-lactate in vascular patients to assess its value as a marker for early postoperative intestinal ischemia detection.
