Vascular graft monitoring

Vascular graft infections.

Vascular procedures are rarely complicated by infection, but if prosthetic vascular graft infection (PVGI) occurs, morbidity and mortality are high. Several patient-related, surgery-related and postoperative risk factors are reported, but they are not well validated. PVGI is due to bacterial colonisation of the wound and the underlying prosthetic graft, generally as a result of direct contamina...

Coxiella burnetii vascular graft infection

BACKGROUND Coxiella burnetii, the causative agent of Q fever, may cause culture-negative vascular graft infections. Very few cases of C. burnetii infection of a vascular graft have been reported. All were diagnosed by serology. CASE PRESENTATION We report the first case of Coxiella burnetii vascular graft infection diagnosed by broad-range PCR and discuss the diagnostic approaches and treatme...

Monitoring of the islet graft.

The Edmonton trials have brought about a marked improvement in the short-term rate of success of islet transplantation with rates of insulin-independence of 80% at 1-year being reported by several institutions worldwide. Unfortunately, this rate consistently decreases to 10-15% by 5 years post-transplantation. Several mechanisms have been proposed to explain this apparent 'islet exhaustion', bu...

Risk Factors for Incident Vascular Graft Infections

Aortic root reconstruction using new vascular graft.

The aim of this study was to determine the feasibility of the new vascular graft for aortic root reconstruction using two different surgical techniques and to evaluate the intermediate clinical and functional results. Between January 2006 and December 2007, a total of 79 patients with aortic root and valve pathologies (chronic aneurysm 70, acute aortic dissection 9) underwent valve-sparing aort...
