The management of vascular prosthetic graft infections confined to the groin continues to be controversial. To critically evaluate this problem, we reviewed the records of our vascular registry from December 1992 through February 1995 and found 17 incidences of groin sepsis involving a vascular prosthesis in 10 patients. These included a proximal prosthetic femoropopliteal bypass (n = 6), an ao...

Computational fluid dynamics(CFD) techniques were used to investigate the hemodynamic effect on EC-IC brain bypass. Local hemodynamic factors at the vascular anastomosis sites have long been thought to play an important role in the platelet activation, growth of intimal hyperplasia and thrombosis of brain bypass anastomosis and hence, affecting graft longevity. In this study, the medical imagin...

OBJECTIVES Mitogen-activated protein kinases (MAPK) are important intermediates in the signal transduction pathways involved in neuronal dysfunction following cerebral ischemia-reperfusion injury. One subfamily, extracellular regulated kinase 1/2, has been heavily implicated in the pathogenesis of post-ischemic neuronal damage. However, the contribution of extracellular regulated kinase 1/2 to ...

Coronary-subclavian steal syndrome results from atherosclerotic disease of the proximal subclavian artery causing reversal of flow in an internal mammary artery used as conduit for coronary artery bypass. This rare complication of cardiac revascularisation leads to recurrence of myocardial ischaemia. When feasible, subclavian angioplasty and/or stent placement can provide acceptable result for ...

ObjectiveThoracofemoral bypass (TFB) has been used infrequently but is an alternative for select patients with aortoiliac occlusive disease. Limited data are available in the reported regarding TFB, all studies small, single-center series. We aimed to describe perioperative and long-term survival, patency, rate of major complications after TFB a large national registry.MethodsThe Vascular Quali...

OBJECTIVES To investigate the effects of the ultrapotent poly(adenosine 5'-diphosphate-ribose) polymerase (PARP) inhibitor INO-1001 on cardiac and mesenteric function during reperfusion in an experimental model of cardiopulmonary bypass with cardioplegic arrest. DESIGN Prospective, randomized, and blinded experimental study. SETTING Research laboratory. SUBJECTS : Twelve anesthetized dogs...

Vascular bypass is a surgical procedure widely used to treat peripheral vascular disease. The intraoperative anesthetic technique and the most appropriate postoperative analgesia for these high-risk patients remain controversial. We present the case of a patient undergoing femoropopliteal-distal bypass in our service, presenting with relevant comorbidities to the choice of anesthetic technique....
