BACKGROUND: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra-anatomical bypass grafting; however, the use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic hemorrhage, limb occlusion, and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...

INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall...

We present an uncommon and underreported complication of coronary artery bypass graft surgery: erroneous anastomosis of the left internal mammary artery to the great cardiac vein. The iatrogenic aorto-coronary arteriovenous fistula with left-to-right shunting resulted in dilation of the coronary sinus, a supporting secondary finding. Factors predisposing to this inadvertent anastomosis include an intramyocardial segment of the left anterior descending coronary artery, demonstrated in this case, as well as epicardial fat and potentially fibrosis of the underlying myocardium...

AIM: extra-anatomic bypass (EAB) remains a viable alternative for lower limbs revascularization if aorto-bifemoral bypass and endovascular therapy are contraindicated. Among EAB, periprosthetic seroma (PS) occurs in about 4% of cases. Diagnostic and therapeutic management, as well as standardized treatment paradigm, are still not well defined. The aim of this study is to report 5 PS cases in EAB and to review literature about similar cases. METHODS: We retrospectively reviewed EAB performed during the period 2002-2015...

A 68year old female patient underwent coronary artery bypass surgery (CABG) 1year previously. At that time she had a giant coronary artery aneurysm (CAA) of the proximal right coronary artery and severe 3 vessel disease including a severe ostial right coronary artery stenosis, severe stenosis of the proximal and mid left anterior descending artery (LAD) and a totally occluded left circumflex artery. She underwent CABG including left internal mammary artery to LAD, aorto-saphenous venous graft (ASVG) to posterior descending artery and ASVG sequential to the first diagonal and obtuse marginal branch...

We present the case of a 33-year-old man with middle aortic syndrome. The final diagnosis was established with magnetic resonance imaging. He underwent a successful aorto-aortic bypass. Two-year follow-up imaging showed the new graft was patent, with no abnormalities at the anastomosis sites. At the last follow-up examination he was asymptomatic with no neurological dysfunction.

Intrapericardial diaphragmatic hernias are reported very rarely. Those of congenital origin are most often diagnosed in neonates, and those caused by indirect blunt trauma occur chiefly in adults. The latter type can be asymptomatic; however, the results of a computed tomographic scan can yield a definitive diagnosis. Once discovered, these hernias should be corrected to avoid severe sequelae such as bowel strangulation and necrosis, peritonitis, mediastinitis, and cardiac tamponade. We report the case of a 78-year-old woman who presented for elective ascending aortic aneurysm repair...

The clinical spectrum of Clostridium difficile infection can range from benign gastrointestinal colonization to mild diarrhea and life threatening conditions such as pseudomembranous colitis and toxic megacolon. Extraintestinal manifestations of C. difficile are rare. Here, we report a patient with a history of an endovascular aortic aneurysm repair (EVAR) presenting with an endovascular leak complicated by C. difficile bacteremia and a mycotic aneurysm. He was successfully treated with an explant of the EVAR, an aorto-left renal bypass, and aorto-bi-iliac bypass graft placement along with a six-week duration of intravenous vancomycin and oral metronidazole...

We propose an arterial network model based on one-dimensional hemodynamic equations to study the behavior of different vascular surgical bypass grafts in the case of an arterial occlusive pathology: a stenosis of the Right Iliac artery. We investigate the performances of three different bypass grafts (Aorto-Femoral, Axillo-Femoral and cross-over Femoral) depending on the degree of obstruction of the stenosis. Numerical simulations show that all bypass grafts are efficient since we retrieve in each case the healthy hemodynamics downstream of the stenosed region while ensuring at the same time a global healthy circulation...

RATIONALE: Sildenafil, a phosphodiesterase-5-inhibitor (PDE5i), could represent a new treatment in addition to the medical treatment and advice to walk in peripheral arterial disease (PAD). PATIENT CONCERNS AND DIAGNOSES: We report a case of a 62-year-old heavy smoker man who developed a buttock claudication and a severe walking limitation following an aorto-bi-femoral bypass in 1992. Since 2003, each year, he has been referred for investigation of bilateral buttock claudication on treadmill using transcutaneous oxygen pressure (tcpO2) measurement during exercise to argue for the vascular origin of the walking impairment...

An elderly man presented with fever and evidence of Salmonella infection, and was diagnosed to have coexisting constrictive pericarditis and mycotic aneurysm of the aortic arch. Pericardiectomy was performed under cardiopulmonary bypass with good result. To avoid deep hypothermic circulatory arrest, an aorto-brachiocephalic bypass, instead of total arch replacement, was performed. This was followed by a staged carotid-carotid bypass, thoracic endovascular stent graft placement. He was subsequently treated with prolonged antibiotics, and inflammatory marker normalized afterwards...
