Mid- and Long-Term Results of Endovascular Treatment in Thoracic Aorta Blunt Trauma

Study Aim. Evaluation of results in blunt injury of the thoracic aorta (BAI) endovascular treatment. Materials and Methods. Sixteen patients were treated for BAI. Thirteen patients had associated polytrauma, 4 of these had a serious hypotensive status and 4 had an hemothorax. In the remaining 3, two had a post-traumatic false aneurysm of the isthmus and 1 had a segmental dissection. In those 13 patients a periaortic hematoma was associated to hemothorax in 4. All patients were submitted to an endovascular treatment, in two cases the subclavian artery ostium was intentionally covered. Results. One patient died for disseminated intravascular coagulation. No paraplegia was recorded. No ischemic complications were observed. A type I endoleak was treated by an adjunctive cuff. During the followup (1–9 years) 3 patients were lost. A good patency and no endoleaks were observed in all cases. One infolding and 1 migration of the endografts were corrected by an adjunctive cuff. Conclusion. The medium and long term results of the endovascular treatment of BAI are encouraging with a low incidence rate of mortality and complications. More suitable endo-suite and endografts could be a crucial point for the further improvement of these results

One-year outcomes after ruptured abdominal aortic aneurysms repair: is endovascular aortic repair the best choice? A single-center experience

Background: Treatment of ruptured abdominal aortic aneurysms (rAAAs) is still burdened by high morbidity and mortality. Although endovascular aortic repair (EVAR) offers encouraging results in elective setting, its role as first-line strategy to treat rAAA is still debated. Our aim was to compare early and late outcomes in patients undergoing open surgical repair (OSR) versus EVAR for rAAAs. Methods: A retrospective review of data extracted from medical records identified 105 consecutive patients with rAAA who were submitted to open or endovascular repairs from 2008 to 2016. The primary end point was to assess the rAAA-related mortality in the immediate postoperative period, within 1 month and 1 year after OSR, and EVAR; secondary endpoints included the following: length of stay, AAA-related postoperative complications such as acute limb ischemia, myocardial infarction, renal and respiratory failure, and rAAA-related re-interventions. Statistical analysis was performed using the Fisher exact test, χ2test, and logistic regression calculations. Early and midterm survival rates were assessed with Cox model. Results: Of the 105 patients with rAAA, 70.48% underwent OSR including 41.89% which was hemodynamically (Hd) unstable and the remaining 29.52% was submitted to rEVAR. (all Hd stable). Compared with EVAR group, the OSR group had a higher rAAA-related mortality rate for both Hd stable and Hd unstable patients: 18.92% vs. 6.45% at 24 hr; (P = 0.185) 39.19% vs. 19.35% at 30 days (P = 0.082); 44.59% vs. 38.71% at 1 year (P = 0.734) If only Hd stable patients were considered, mortality following OSR and EVAR was as follows: 6.98% vs. 6.45% at 24 hr (P = 0.703); 27.91% vs. 19.35% at 30 days (P = 0.567); 32.56% vs. 38.71% at 1 year (P = 0.764). Mean length of stay for patients was 15 days after OSR and 10 days after rEVAR (P = 0.002). At 1-year follow-up, the overall rAAA-related complications incidence was higher in the rEVAR group than that in the OSR group (47.85% vs. 18.33%; P = 0.008); re-interventions were 18.33% in OSR group vs. 21.82% in EVAR group (P = 0.917). Cox model showed that instability and coronary artery disease were predictors of overall mortality of rAAAs. Conclusions: EVAR does not independently reduce 1-year mortality in comparison with OSR in Hd stable patients. Urgent EVAR for rAAAs in unstable patients can be limited by logistical problems. It follows that patients selected for OSR have a more complex aortic anatomy and worse Hd status than those submitted to rEVAR. rEVAR burdened by a higher incidence of procedure-related complications than OSR. Reconfiguration of acute aortic services and establishment of standardized institutional protocols might be advisable for improvements in the management of ruptured AAA. A careful evaluation of whether the benefits of an endovascular strategy translate into long term benefit is needed before definitive conclusions can be drawn about the advantages of EVAR as first-line strategy for ruptured aneurysms

Long-term follow-up of Bentall procedure using the Perimount bioprosthesis and the Valsalva graft

Bentall procedure is the gold standard for aortic root pathologies when valve repair is not feasible. The development of durable bioprosthetic valves and improved vascular conduits allowed the implementation of bioprosthetic composite grafts; hereby, we performed a retrospective analysis of long-term follow-up of Bentall procedure using the Valsalva graft and the Perimount Magna Ease prosthesis

Optimized use of the "skirt" of the Valsalva graft for the completion Bentall

We report the case of a patient with an aortic root aneurysm who had previously undergone aortic valve replacement with a large mechanical prosthesis which proved to be normally functioning at the time of reoperation. We describe a new technique of replacing the aortic root while retaining the existing aortic valve similar to the "completion Bentall" procedure using a 32 mm Valsalva graft by suturing the skirted portion of the graft to the sewing ring of the mechanical valve. The ability of the skirt to increase its diameter was the key of this approach

A direct correlation between commissural orientation and annular shape in bicuspid aortic valves: a new anatomical and computed tomography classification

The shape of the aortic annulus is still under debate. Recent findings suggest a possible gradual spectrum of circularity from tricuspid aortic valves (TAVs), to type 1 bicuspid aortic valves (BAVs) to type 0 BAVs. BAVs have been recently classified in a symmetrical (type A), asymmetrical (type B) or very asymmetrical (type C) phenotype according to the commissural orientation (CO) (160°-180°, 140°-159° and 120°-139°, respectively). The aim of this study is to verify in BAVs the correlation between the aortic annular shape and the CO of valve cusps and to suggest a new anatomical and geometric classification of BAVs based on CO and annular shape

External Stents for Vein Grafts in Coronary Artery Bypass Grafting: Targeting Intimal Hyperplasia

Progressive saphenous vein graft (SVG) failure remains a key limitation to the long-term success of coronary artery bypass grafting (CABG). SVG disease after the first year is dominated by intimal hyperplasia, which predisposes the SVG to thrombosis and accelerated atherosclerosis. The objective of this study was to review and summarize the latest experimental and clinical data on the use of mechanical external stents for vein grafts

Semeiotica dell'apparato Cardiovascolare

L'apparato cardiovascolare è costituito dal cuore, dalle arterie, dalle vene e dai vasi linfatici. Sebbene molte patologie che coinvolgono tale complesso sistema si avvalgano di terapia medica e dunque vengano trattate in testi di terapia medica, molte altre possono essere risolte mediante approccio chirurgico classico, endovascolare o di radiologia interventistica e richiedono un approccio metodologico chirurgico
