Sometimes the superficial temporal artery (STA) is not available for an extracranial-intracranial (EC-IC) bypass procedure. An alternative vessel for an EC-IC bypass is the posterior auricular artery (PAA) if it extends to the temporoparietal area with a diameter large enough. We assessed the prevalence of an appropriate PAA as an ...

We describe the case of a 59-year old male patient undergoing combined coronary artery bypass grafting and aortic valve replacement. Manipulation of the heart during cardiopulmonary bypass significantly decreased venous return. Several measures were necessary to improve venous return to a level at which continuation of the procedure was safe. ...

We have previously shown that mitochondrial uncoupling protein-2 (UCP-2) is increased in a swine model of hibernating myocardium (HM). Although UCP-2 reduces oxidant stress, it can promote inefficiency of the electron transport chain. In this study, we tested whether UCP-2 remains increased in revascularized HM (RHM) after coronary artery bypass ...

Pulmonary vein stenosis (PVS) is a relentless disease with a poor prognosis. Although surgical repair can effectively treat "downstream" (near left atrial junction) PVS, residual "upstream" (deep in lung parenchyma) PVS commonly dictates long-term survival. Our initial studies revealed an association between PVS and transforming growth factor-β signaling, which led ...

Conventional repair of pararenal aortic aneurysms has been a technically challenging operation, with a significant morbidity rate of 28-35%. Endovascular stent grafting requires satisfactory landing zones for stent graft anchoring. Therefore, pararenal abdominal aortic aneurysms are usually contraindicated for this procedure because of difficulties associated with proximal graft fixation. In ...
