Polyester Vascular Graft Material and Risk for Intracavitary Thoracic Vascular Graft Infection1

Risk Factors for Incident Vascular Graft Infections

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...

In situ graft-trimming method using polyester vascular prosthesis for inferior vena cava reconstruction after hepatectomy.

Hepatectomy for secondary liver cancer that has invaded the inferior vena cava (IVC) can be the only way to achieve long-term survival. We describe a method for hepatectomy combined with partial IVC resection without venous bypass circulation and an in situ graft-trimming method to avoid graft size mismatch after reconstruction. We carried out left hepatectomy extended to segment 1 with partial...

Genetic Algorithms and Vascular Graft Optimization

1. Abstract The optimization of graft and anastomotic configurations with regard to blood dynamics is the major target of this study. A developed multi-objective genetic algorithm is considered in order to reach optimal graft geometries for idealized arterial bypass systems of fully occluded host arteries. An artificial neural network simulating hemodynamic specific conditions is introduced in ...
