Occlusive vascular disease is a widespread abnormality leading to lethal or debilitating outcomes such as myocardial infarction and stroke. It is part of atherosclerosis and is evoked by clinical procedures including angioplasty and grafting of saphenous vein in bypass surgery. A causative factor is the switch in smooth muscle cells to an invasive and proliferative mode, leading to neointimal h...
We have studied the effect of thiopentone, etomidate and propofol on systemic vascular resistance (SVR) during cardiopulmonary bypass with constant pump flow in 30 patients undergoing elective coronary artery bypass surgery. SVR decreased to 78% of control values after thiopentone 4 mg kg-1, to 72% of control after etomidate 0.3 mg kg-1, and to 68% of control after propofol 2 mg kg-1; it return...
PURPOSE To determine whether the use of cell salvage reduces the proportion of patients receiving at least one unit of allogeneic packed red blood cells during the perioperative period of an elective vascular surgery. SOURCE We identified all relevant articles through the combined use of electronic searches of the MEDLINE and EMBASE databases, the Cochrane library as well as hand searching of...
The coronary circulation of anesthetized dogs was tested for the presence of vascular waterfalls by manipulating coronary arterial and coronary venous pressures. The left main coronary artery and the coronary sinus were cannulated, and relationships between coronary artery pressure, coronary sinus pressure, and coronary flow were studied. Experiments were conducted during diastolic arrests, und...
T he epidemiologic burden of peripheral artery disease (PAD) is remarkable with prevalence ranging from 3% to 10%, rising to 15% to 20% in patients over 70 years. Symptomatic PAD with intermittent claudication has a prevalence of up to 60% in patients over 60 years of age and the largest prospective study demonstrates an incidence of critical limb ischemia of 220 cases per 1 million population....
Vascular complications are particularly feared in oncological spine surgery for the contiguity and possible involvement of major vessels; vascular assistance is therefore often required during these procedures. A classification different degrees vessel lacking, leading to difficulties preoperative risk assessment. The aim this study outline a computed tomography angiography-based system by spin...
CONTEXT Iatrogenic vascular problems due to laparoscopy are a well recognized problem and lead to significant repercussions. In this context, a ten-year review of cases topic is presented, based on experience gained while heading two important vascular surgery services. CASES Five patients with vascular injuries during elective laparoscopy are described. These patients presented with seven le...
As part of a prospective study of the neurologic and neuropsychological complications of coronary artery bypass graft surgery, 312 patients were compared with a control group of 50 patients undergoing major surgery for peripheral vascular disease. The purpose of comparing the 2 groups was to determine to what extent neurologic complications after heart surgery can be attributed to cardiopulmona...
Moyamoya disease (MMD) involves progressive occlusion of the intracranial internal carotid artery resulting in formation of moyamoya-like vessels at the base of the brain. It can be characterized by hemorrhage or ischemia. Direct vascular bypass is the main and most effective treatment of MMD. However, patients with MMD differ from those with normal cerebral vessels. MMD patients have unstable ...
