Infrarenal versus Suprarenal Abdominal Aortic Aneurysms: Comparison of Associated Aneurysms and Renal Artery Stenosis.

Background: The aim of our study is to assess the prevalence of concomitant arterial abnormalities (true aneurysms of iliac, common femoral, renal, visceral arteries and stenoses of iliac and renal arteries) in patients with abdominal aortic aneurysm, and to evaluate whether the type of the aneurysm (suprarenal versus solely infrarenal) is associated with this prevalence.

Methods: In this retrospective cross-sectional study, we assessed computed tomography angiography scans of 933 patients with abdominal aortic aneurysm, including thoracoabdominal aortic aneurysms type II-IV, with no history of abdominal aortic surgery. We compared 2 groups of patients: group 1 (n = 859) with solely infrarenal abdominal aortic aneurysm and group 2 (n = 74) with the suprarenal aneurysm component.

Varicose veins of lower extremities, hemodynamics and treatment methods.

Chronic venous insufficiency is one of the most common disorders of the vascular system, affecting approximately 50% of adults. If left untreated it can lead to a number of complications, including venous ulceration and venous thrombosis. This review paper outlines the epidemiology and ethiopathogenesis of the disease with regard to hemodynamics and microcirculation disturbances.

Reconstruction of the right atrium and superior vena cava with extracellular matrix.

We describe our technique for reconstructing the free right atrial wall and superior vena cava using CorMatrix (CorMatrix Alpharetta, GA, USA) extracellular matrix following resection of a large leiomyosarcoma.

The impact of weather factors, moon phases, and seasons on abdominal aortic aneurysm rupture.

Background: Several studies have documented that weather factors, seasons of the year, time of the day, and even changes in moon phases have an impact on the occurrence of rupture of an abdominal aortic aneurysm (RAAA); however, the available data are confounding. The objective of this study was to determine the impact of these factors on the prevalence and mortality rate of RAAA.

Methods: This is a retrospective analysis of medical records of patients treated for RAAA over a 10-year period.

Infected calcified homograft root: a sutureless solution.

Aortic valve reoperation after homograft root implantation is high risk and may be technically challenging. Dense calcification of the annulus may prevent suture placement and often necessitates impromptu high-risk redo root replacement. Although transcutaneous aortic valve implantation is an attractive option in such scenarios, in the context of endocarditis it is contraindicated.
