Early Postoperative Renal Dysfunction Predicts Long-Term Renal Function Degradation after Type IV Thoracoabdominal Aortic Aneurysm Surgical Repair.

Background: Type IV thoracoabdominal aortic aneurysm surgical repair is often complicated by postoperative acute kidney injury. The aim was to evaluate early renal injury influence on long-term renal function.

Methods: All type IV thoracoabdominal surgical repair performed between January 2000 and January 2014 in our tertiary hospital were included in this retrospective observational study.

A case of a 15-year evolution of a coral reef aortic lesion.

We are reporting here the 15-year history of a patient affected by a chronic and evolutive coral reef aorta successfully treated by repeated revascularization.

Operated descending thoracic and thoracoabdominal atherosclerotic aortic aneurysm prognosis.

Background: The long-term survival of patients treated from descending thoracic aneurysm (DTA) is well known, more than those treated from a thoracoabdominal aortic aneurysm (TAAA). Moreover, studies are rarely focused on the aneurysmal etiology and include both degenerative and post dissecting aneurysms. The aim of this study is to compare the long-term survival of patients operated from DTA or TAAA due to degenerative atherosclerosis.

Long-term Outcomes after Transplant Renal Artery Stenosis Surgery.

The occurrence of transplant renal artery stenosis (TRAS) ranges from 1 to 23% and is associated with resistant hypertension, volume overload, graft dysfunction, and poor long-term graft and patient survival. Enhancing graft availability with expanded criteria donors results in the transplantation of kidneys with atherosclerotic arteries, increasing the risk of vascular complications. Although endovascular management is the first-line strategy in this context, in some patients, surgery has to be considered.

Passive Temporary Visceral Shunt from the Axillar Artery as an Adjunct Method during the Open Treatment of Thoracoabdominal Aortic Aneurysm.

Background: Distal aortic retrograde perfusion systems like the left heart bypass or femoro-femoral extracorporeal circulation are the methods of reference for organ protection during direct approaches to thoracoabdominal aortic aneurysms. The aim of this work was to evaluate the use of a passive arterial shunt to reduce visceral ischemia during aortic operations when occlusive diseases of the iliac arteries make distal aortic retrograde perfusion inappropriate.

Methods: Ten patients affected by a Crawford type III thoracoabdominal aneurysm (TAA) were operated on between January 2013 and January 2015 with the use of a temporary shunt inserted onto the left axillar artery that allows visceral perfusion immediately after the aorta is opened.

Open aortic repair up to previous abdominal aortic surgery.

Background: To determine whether direct open repair of thoracoabdominal aortic aneurysms after previous abdominal aortic surgery is a safe option.

Methods: Ten patients were operated between January 2006 and January 2012. Mean age was 70 years (62-78 years).

Intraoperative factors affecting renal outcome after open repair of suprarenal aortic aneurysms.

Background: The open repair of suprarenal aortic aneurysm requires supraceliac aortic cross-clamping and separate renal artery reconstruction. The aim of this study was to determine the intraoperative factors responsible for postoperative renal dysfunction.

Methods: Between January 1, 2000 and May 31, 2010, 54 suprarenal aortic aneurysms were repaired at our center (mean age of the patients, 66 ± 8 years).

A rare case of visceral arterial stenoses in Williams-Beuren syndrome treated by complex revascularization.

Williams-Beuren syndrome is a rare neurodevelopmental disorder. We present the case of a 27-year-old patient with Williams-Beuren syndrome and a juxtarenal abdominal aorta coarctation. As arterial hypertension (AHT) was not controlled, bilateral renal artery bypasses were performed at the age of 2 years by means of a hepatorenal bypass and a splenorenal bypass.

Open repair of extensive thoracoabdominal and thoracic aneurysm: a preliminary single-center experience with femorofemoral distal aortic perfusion with oxygenator and without cerebrospinal fluid drainage.

Thoracoabdominal aortic aneurysms (TAAA) and extensive thoracic descending aortic aneurysms (TDA) are not accessible through standard endovascular treatment. Fenestrated and branched endograft technology was developed rapidly without widespread application. The aim of this study was to review our open repair (OR) experience of TAAA and TDA.

Mycoplasma hominis wound infection after a vascular allograft.

Cases of Mycoplasma hominis infections after allograft are rare. We report a case of M. hominis wound infection after a vascular allograft.

High temperature NMR study of the local structure of molten LaF3-AF (A = Li, Na, K and Rb) mixtures.

The local structures of molten lanthanum alkali fluoride binaries have been studied using HT NMR technique. The chemical shifts of (19)F, (23)Na and (139)La in solid and in liquid have been compared for AF (A = alkali) and LaF(3). In pure molten alkali fluorides, the polarisability of anion-cation pairs appears to be a key parameter to depict the observed evolution of (19)F chemical shifts.

[Heart injury following closed thoracic injury].

A 60-year-old man, was admitted in the emergency ward, following a motor vehicle accident. At the time of arrival his clinical state was stable. The initial investigations showed a moderate left haemopneumothorax and fractured ribs.

[Azygos vein injury. A new complication of upper digestive endoscopies].

A patient presented with a ruptured azygos vein following esophagoscopy. The diagnosis was difficult. Selective angiography was helpful and surgical treatment ensured good result.
