Intraocular pressure was measured in 24 patients undergoing elective cardiopulmonary bypass surgery. There was a rapid rise when the bypass circulation began, and this was maintained for about 30 minutes. A simultaneous drop in arterial perfusion pressure and packed cell volume occurred. We suggest that marked haemodilution is responsible for this effect, through increased ocular blood flow and...

Endovascular treatment through femoropopliteal and infragenicular percutaneous transluminal angioplasty, both in native vessels and in bypass salvage, has been an emerging technique in recent years. However, in some cases, a difficult anterograde access in distal occlusions has limited the technical success of this procedure. Combined subintimal arterial flossing with antegrade-retrograde inter...

THE THERAPEUTIC VALUE of coronary arterial bypass grafting is suggested by many favorable reports which stress particularly the relief of angina pectoris.' However, definitive statements regarding the effectiveness of this procedure in improving myocardial function, preventing myocardial necrosis and death from myocardial disease, and in producing permanent (or sustained) relief of angina are n...

INTRODUCTION A hybrid Viabahn-assisted bypass (VAB) technique is introduced for revascularizing chronic total occlusion (CTO) in superficial femoral artery (SFA) when bypass surgery is difficult or endovascular intervention fails. REPORT This technique combines extra-arterial flossing wiring with antegrade-retrograde intervention via traditional open exposure of middle SFA and deploying a Via...

Below-The-Knee (BTK) arterial occlusive disease with smalldiameter blood vessels, blood should have low flow from far the way. The disease is often detected when there appear signs of critical limn ischemia. Previously, BTK arterial occlusive disease treatment is often bypass of veins, this is serious surgery that efficiency is not high. Especially in older patients, many factors increase the r...

The reduced basis method on parametrized domains is applied to approximate blood flow through an arterial bypass. The aim is to provide (a) a sensitivity analysis for relevant geometrical quantities in bypass configurations and (b) rapid and reliable prediction of integral functional outputs (such as fluid mechanics indexes). The goal of this investigation is (i) to achieve design indications f...

A 52-year-old man, who presented with two-vessel coronary artery disease and severe arterial occlusive disease with occlusions and/or stenoses of all aortic arch branches, underwent simultaneously coronary artery bypass grafting and bilateral aortic-subclavian as well as left-sided aortic-carotidal bypass grafting.

Between December 1990 and August 1999, a consecutive series of 494 patients underwent coronary artery bypass grafting, while 19 (3.8%) patients underwent isolated reoperative coronary bypass grafting. The mean age of 16 males and 3 females who underwent reoperation was 63.4 +/- 6.4 years. The mean interval from the initial operation to reoperation was 50.7 +/- 61.0 months (range 3 days to 16 ye...

Coronary artery bypass grafting (CABG) is the standard surgical procedure for the treatment of advanced coronary artery disease. CABG surgery has been demonstrated to improve symptoms and, in specific subgroups of patients, to prolong life. Despite its success, the long-term outcome of coronary bypass surgery is strongly influenced by the fate of the vascular conduits used. Impressive long-term...
