Choice of the operative approach in two cardiosurgical patients assisted by preoperative computed tomography: Case Report

1988

The perioperative course of two patients is exemplified to demonstrate the significance of the preoperative thoracic computed tomography for the selection of a proper surgical approach.

Acute aortic dissection

2011

An acute aortic syndrome with simultaneous presence of a penetrating aortic ulcer, an intramural haematoma, a thoracic aortic dissection and an abdominal aortic aneurysm rupture has not previously been reported. Herein, we describe our experience with a patient treated by endovascular means with an 8-year follow-up.

Systemic pulsatile pressure in type II endoleaks after stent grafting of experimental abdominal aortic aneurysms.

2003

Purpose: To investigate pressure and maximum rate of rise of systolic pressure (peak dP/dt) in completely excluded aneurysms and endoleaks to determine the hemodynamic impact of endoleaks. Methods: In mongrel dogs (n = 36) experimental aneurysms were created by insertion of a patch (portion of rectus abdominis muscle sheath) into the infrarenal aorta. In group I (n = 18), all aortic branches of the aneurysm were ligated and all aneurysms were completely excluded by stent grafts. Group II (n = 18) consisted of aneurysms with patent aortic side branches that represented sources of endoleaks. One week (n = 12), six weeks (n = 12), and six months (n = 12) after stent grafting, hemodynamic measu…

CRT-723 Is the Sporadic Thoracic Aortic Aneurysm the Result of an Inflammatory Process?

2014

Sporadic thoracic aortic aneurysm (S-TAA) is potentially devastating with severe morbidity and mortality. The histopathologic underlying abnormality of both ascending aortic aneurysm and dissection is medial degeneration, a pathological entity initially described as no inflammatory lesions of smooth

Einfluss von Typ-II-Endoleaks auf die Größenänderung und Hämodynamik experimenteller Aortenaneurysmen nach endovaskulärer Therapie

2003

PURPOSE To evaluate the aneurysm volume and the intra-aneurysmatic pressure and maximal pressure pulse (dp/dtmax) in completely excluded aneurysms and cases with endoleaks. MATERIALS AND METHODS In 36 mongrel dogs, experimental autologous aneurysms were treated with stent-grafts. All aortic side branches were ligated in 18 cases (group I) but were preserved in group II (n = 18). Aneurysm volumes were calculated from CT scans before and after intervention, and from follow-up CT scans at 1 week, 6 weeks and 6 months. Finally, for hemodynamic measurements, manometer-tipped catheters were introduced into the excluded aneurysm sac (group I and II), selectively in endoleaks (group II), and intral…

Subclinical atherosclerosis: independent predictor of cardiovascular events in a 20-years follow up of patients with or without metabolic syndrome

2013

Purpose: To evaluate the influence of carotid atherosclerosis and metabolic syndrome (MetS) on the prediction of cardiovascular events during a 20-years follow-up. Methods: We studied a population of 529 asymptomatic patients, divided into 2 groups according to the results of the carotid ultrasound evaluation: one without atherosclerotic lesions (198 patients) and a second one with an increased carotid IMT or asymptomatic carotid plaque (331 patients). In each of these groups, we identified two subgroups of subjects with and without MetS. Cardiovascular endpoints were investigated in a 20-years follow-up: acute myocardial infarction, angina, transient ischemic attack, ischemic stroke, abdom…

Evidence, Lack of Evidence, Controversy, and Debate in the Provision and Performance of the Surgery of Acute Type A Aortic Dissection

2011

Acute type A aortic dissection is a lethal condition requiring emergency surgery. It has diverse presentations, and the diagnosis can be missed or delayed. Once diagnosed, decisions with regard to initial management, transfer, appropriateness of surgery, timing of operation, and intervention for malperfusion complications are necessary. The goals of surgery are to save life by prevention of pericardial tamponade or intra-pericardial aortic rupture, to resect the primary entry tear, to correct or prevent any malperfusion and aortic valve regurgitation, and if possible to prevent late dissection-related complications in the proximal and downstream aorta. No randomized trials of treatment or t…

Klassifikation und Therapie von Endolecks nach endovaskulärer Behandlung von abdominellen Aortenaneurysmen

2005

This article describes the classification of endoleaks after endovascular treatment of abdominal aortic aneurysms, thereby summarizing the most important problems of this endovascular technique. The correct classification of endoleaks is a prerequisite for interdisciplinary discussion. It is indispensable for professional reporting of the pathological findings and for the decision making as to the adequate treatment of endoleaks. Irrespective of the types of stent graft and property of the material, five endoleak types are defined in the literature: leakage at the anchor sites (type I); leakage due to collateral arteries (type II); defective stent grafts (type III); leakage due to porosity …
