Incidence and predictors of myocardial and kidney injury following endovascular aortic repair: a retrospective cohort study.

Purpose: We performed a retrospective cohort study in patients who underwent endovascular aneurysm repair (EVAR) to determine the incidence and predictors of myocardial injury and acute kidney injury (AKI).

Methods: We included 267 consecutive patients who underwent EVAR at two tertiary centres in Canada and Poland. The primary outcome was myocardial injury during hospital stay after EVAR defined as a troponin elevation (ultra-sensitivity troponin I Vidas ≥ 19 ng·L, non-high-sensitivity troponin I Vidas ≥ 0.

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.

Short-term outcomes of endovascular repair of abdominal aortic aneurysm, including ruptured cases.

Introduction: Endovascular aneurysm repair as a minimally invasive alternative has become a commonly used surgical method for treating patients with abdominal aortic aneurysm (AAA).

Aim: To analyze short-term outcomes of endovascular treatment of AAA patients, including ruptured cases.

Material And Methods: From 2010 to 2015, 247 patients with AAA were treated using the endovascular aneurysm repair technique.

Chronic cerebrospinal venous insufficiency is unlikely to be a direct trigger of multiple sclerosis.

Background: Chronic cerebrospinal venous insufficiency, a vascular pathology affecting the veins draining the central nervous system can accompany multiple sclerosis and is suspected to be involved in its pathogenesis.

Objective: This study was aimed at exploring a potential role for chronic cerebrospinal venous insufficiency in triggering multiple sclerosis. If it were venous abnormalities responsible for neurological pathology, one should expect negative correlation, i.

Internal jugular vein entrapment in a multiple sclerosis patient.

We describe a multiple sclerosis patient presenting with compression of the internal jugular vein caused by aberrant omohyoid muscle. Previously this patient underwent balloon angioplasty of the same internal jugular vein. Ten months after this endovascular procedure, Doppler sonography revealed totally collapsed middle part of the treated vein with no outflow detected.

Biophysics of venous return from the brain from the perspective of the pathophysiology of chronic cerebrospinal venous insufficiency.

This article discusses the biophysical aspects of venous outflow from the brain in healthy individuals and in patients with chronic cerebrospinal venous insufficiency. Blood flows out of the brain differently, depending on body position. In the supine position it flows out mainly through internal jugular veins, while in the upright position it uses the vertebral veins.

An endovascular treatment of Chronic Cerebro-Spinal Venous Insufficiency in multiple sclerosis patients - 6 month follow-up results.

Objective: In this study, the mid-term results (6 month follow-up) of the endovascular treatment in patients with Chronic Cerebro-Spinal Venous Insufficiency (CCSVI) and multiple sclerosis (MS) were prospectively evaluated.

Methods: Thirty-six patients with confirmed MS and CCSVI underwent endovascular treatment by the means of the uni- or bilateral jugular vein angioplasty with optional stent placement. All the patients completed 6 month follow-up.

Magnetic Resonance Venography of chronic cerebrospinal venous insufficiency in patients with associated multiple sclerosis.

Background: Multiple sclerosis (MS) is a chronic disease with not well understood etiology. Recently, a possible association of MS with compromised venous outflow from the brain and spinal cord has been studied (chronic cerebrospinal venous insufficiency - CCSVI). Angioplasties of internal jugular veins (IJV) and azygous vein (AV) have given promising results, with improvements in patients' clinical status.

Angiosarcoma arising within a Malignant Endovascular Papillary Angioendothelioma (Dabska tumor).

We report an angiosarcoma arising within a malignant endovascular papillary angioendothelioma (Dabska tumor) in soft tissue of the upper thigh/buttock of a 42-year-old woman. Although neoplastic progression within a vascular tumor of an existing low-grade lesion into DT has been described so far, we seem to be the first to report transformation of DT into an angiosarcoma.

Reinterpreting the magnetic resonance signs of hemodynamic impairment in the brains of multiple sclerosis patients from the perspective of a recent discovery of outflow block in the extracranial veins.

Multiple sclerosis patients examined with perfusion magnetic resonance (MR) imaging techniques have been found to have patterns of abnormal blood flow. These include prolonged mean transit time, a trend toward decreased cerebral blood flow in the area of plaques, and decreased cerebral blood flow and prolonged mean transit time within normal-appearing white matter. Increased cerebral blood flow and volume and decreased mean transit time (compared with the baseline values before the relapse) were found to precede the development of plaques.

Pneumatosis cystoides intestinalis--a report of two cases.

The authors present two cases of an extremely rare pneumatosis cystoides intestinalis of large and small intestine in a 48-year-old male and in a 77-year-old female surgical patients.

[Aorto-caval fistula as a results of abdominal aortic aneurysm rupture imitating acute renal insufficiency].

Aorto-caval fistula (ACF) is a rare complication of abdominal aortic aneurysm. It occurs in 1-6% of cases. The classic diagnostic signs of an ACF (pulsatile abdominal mass with bruit and right ventricular failure) are present only in a half of the patients.
