Surgical management of concurrent, coeliac and bilateral iliac artery aneurysms.

A 76-year-old man was admitted with bilateral common iliac artery aneurysms found incidentally on computed tomography. Transfemoral digital subtraction arteriography demonstrated atherosclerotic plaques in the aorta with bilateral common iliac artery aneurysms and a coeliac axis aneurysm. The coeliac artery aneurysm was resected and an aortobifemoral bypass performed with reimplantation of the inferior mesenteric artery into the prosthesis. The patient was well when discharged 2 weeks after operation. The incidence, natural history and management of coeliac axis and iliac artery aneurysms are reviewed.

Coronary artery bypass grafting on the beating heart using the Octopus method.

STUDY OBJECTIVE: To study the usefulness and effectiveness of off-pump coronary bypass grafting with the Octopus heart stabilizing device. METHOD: The files of thirty-one patients undergoing coronary artery bypass with the aid of the Octopus heart stabilizing device between April 1996 and October 1998 were studied retrospectively. Patients were divided into group A (n = 23), patients with single or double vessel disease and technically suitable coronary lesions for off-pump procedure and group B (n = 8), patients with multiple vessel disease considered to be with excessive risk for cardiopulmonary bypass due to poor general condition combined with renal failure and/or chronic obstructive pulmonary disease. Standard median sternotomy (n = 27), lateral thoracotomy (n = 1) or minithoracotomy (n = 3) were performed for access and for harvesting the left internal mammary artery (LIMA). MEASUREMENTS AND RESULTS: The mean number of bypasses was 1.2 and 1.1 in groups A and B, respectively. Thirty patients received a LIMA graft to the left anterior descending artery (LAD). Homologous blood transfusions were needed in five patients (21%) in group A and four (50%) in group B. There were no wound infections or neurologic complications. All patients in group A survived and are asymptomatic. One patient in group B died of septic shock, two have residual angina pectoris or dyspnea, and five are asymptomatic. CONCLUSION: Coronary artery bypass using the Octopus heart stabilizing device proved to be a safe and effective technique resulting in complete revascularization in group A patients with no mortality. Incomplete revascularization may offer a substantial benefit to patients who cannot tolerate cardiopulmonary bypass due to poor general condition. We prefer median sternotomy, allowing precise harvesting of the internal mammary artery and more precise anastomoses without increased morbidity.

Emergency ventricular assist device: better survival rates in non-post cardiotomy-related cardiogenic shock.

OBJECTIVE: The Abiomed BVS 5000 ventricular assist device (VAD) has been approved in Belgium for emergency cardiac support in patients with postcardiotomy failure with the aim of native heart function recovery. Other indications have emerged from world wide experience, but the indication and usefulness of emergency implantation of assist devices is often debated. METHODS: To decide which patients benefit most from emergency ventricular assist device implantation, we retrospectively reviewed our results of mechanical circulatory support with Abiomed in 20 patients over a 4-year period. Fifteen patients with mean age 58 +/- 6 years experienced postcardiotomy failure and underwent biventricular assist device (BVAD) implantation (group A), after elective (n = 9) or after emergency coronary artery bypass grafting (CABG) (n = 6). Five patients (group B), with mean age 35 +/- 19 years, had an implantation for other underlying conditions: hypertrophic cardiomyopathy (n = 3), myocarditis (n = 1) and primary cardiac allograft failure (n = 1). RESULTS: Of these two groups, eight and two patients respectively needed cardiopulmonary resuscitation before VAD implantation. The mean duration of support in both groups was 5.8 (range 12 h-13 days) and 4.4 days (range 2 h-9 days) respectively. Six and two patients could be weaned from the device and nine and one patients respectively, died on the device. Two patients in group B underwent successful heart transplantation and four patients in group A died after weaning. Two patients in the postcardiotomy group and four patients in group B survived (13% and 80%) with an overall survival and discharge rate of 30%. CONCLUSION: Although sample sizes are small, better survival rates with emergency Abiomed BVS 5000 implantation were obtained in the non postcardiotomy group (group B). For patients in the postcardiotomy group, outcome was negatively influenced by cardiac arrest and resuscitation before urgent CABG. Since death is the only alternative for these patients in cardiogenic shock and organ recovery cannot be predicted, we continue to consider emergency VAD implantation in this patient population.
