Preoperative coronary angiography showed that the significant coronary artery disease (CAD) was present in 47% of patients with thoracic aortic aneurysm (TAA), abdominal aortic aneurysm (AAA), or aortoiliac occlusive disease (A.I). Fifty-seven patients underwent the both coronary artery and great vessel diseases on the simultaneous or sequential stage. As CAD, 13 patients had one vessel disease (VD), 18 had two-VD, 26 had three-VD and 4 of them had left main trunk lesions. As great vessel diseases, 23 patients had A-I, 20 had AAA, 8 had TAA, 5 had TAA+AAA, and 1 had TAA+A-I. There were 4 early deaths (7%) in 57 patients, and 4 (3%) in total 120 coronary and great vessel's operative procedures. The 5-year survival rates were 57.4 +/- 15.5% for TAA, 87.1 +/- 8.5% for AAA and 63.9 +/- 11.1% for A-I, which were not significantly different from those of patients without CAD, respectively except for TAA. The present data suggest that preoperative coronary angiography and CABG in the selected patients may have the beneficial effects on survival and quality of life.

A 70-year-old man was successfully operated on A-C bypass for coronary triple vessel disease and replacement of abdominal aortic aneurysm. The two different procedures were performed simultaneously under cardio-pulmonary bypass. This simultaneous operation can provide benefits of shortening operating time and of clamping easily the abdominal aorta.

The purpose of this study was to investigate the levels of various plasma amino acids in 30 burned patients (76.83 +/- 14.4% TBSA, with III. 42.16 +/- 27.95% TBSA) and identify the alterations in plasma profiles characteristic of patients who later developed MSOF (n = 16) versus those who did not developed MSOF (n = 14). The levels of amino acids were analyzed by use of individual amino acid and the ratio of BCAA (Branched-Chain Amino Acid) to AAA (Aromatic Amino Acid) and Phe to Tyr. The results showed that: (1) The patients who developed MSOF later had significantly lower levels of Pro, Gly Arg, Val, Leu, Ile, and BCAA/AAA, and higher values of Phe, Trp, Tyr, and Phe/Tyr than those who did not develop MSOF. (2) The incidence rate of MSOF increased as the ratio of BCAA/AAA decreased. When the ratio lower than 1.5, eight of ten patients developed MSOF. (3) The higher of the values of Phe/Tyr, the more of the incidence of MSOF. When Phe/Tyr was higher than 2.0, six of seven developed MSOF. These data suggested that: (1) Both BCAA/AAA and Phe/Tyr were the indices of prognosis available in severe trauma patients. (2) Alterations in metabolism as reflected in plasma amino acids patterns were thus critical indicators of MSOF. (3) Liver may be the earliest involved and the most severe injured organ in multiple system organ failure.

A case of abdominal aortic aneurysm associated with renovascular hypertension in a 3-year-old boy is reported. The child was treated by resection of the aneurysm and replacement with a 12 mm polyester (Dacron) bifurcated graft. The cause of the aneurysm was not revealed by clinical and pathologic examination. In addition to the case report, the Japanese-language literature is reviewed. The most frequently reported etiologic factor was Kawasaki disease; we could not find any evidence of connective-tissue disorder as a cause for abdominal aortic aneurysms occurring in children.

Patients presenting for abdominal aortic surgery have a high incidence of vascular disease elsewhere, manifested primarily by hypertension, coronary and cerebrovascular disease, as well as co-existing respiratory, renal and metabolic disorders. Routine clinical assessment, electrocardiogram, chest roentgenograms, resting and exercise radionuclide ventriculography and echocardiography, dipyrdiamole-thallium scanning are all designed to assess the functional status of the myocardium and to detect the presence of significant coronary artery disease. Patients with no abnormalities on physical examination, routine evaluation and no redistribution on dipyridamole-thallium scanning should proceed to surgery with the expectation of very low perioperative cardiac risk. Patients with evidence of coronary artery disease and significant redistribution on dipyridamole-thallium scan should undergo coronary angiography and possible myocardial revascularization before definitive aortic vascular surgery. For high cardiac risk patients with no bypassable lesions presenting for abdominal aortic aneurysm resection a conservative policy of serial three monthly ultrasound or CT assessment may be adopted, with selective resection for rapid aneurysm expansion or symptom development. A variety of extra-anatomical and angioplastic techniques is available for similar high cardiac risk patients with aortoiliac occlusive disease. The haemodynamic consequences of aortic cross-clamping, especially in aneurysm patients, include a significant reduction in stroke volume, cardiac index, and myocardial oxygen consumption with an increased systemic vascular resistance. Patients with coronary artery disease may respond to aortic cross-clamping by increasing pulmonary capillary wedge pressure and by demonstrating ECG evidence of myocardial ischaemia. Pulmonary artery catheterization is especially indicated in patients with a history of previous myocardial infarction, angina or signs of cardiac failure and in patients with evidence of diminished ejection fraction, abnormal ventricular wall motion or myocardial redistribution on preoperative scanning. The more widespread application of intraoperative transoesophageal two-dimensional echocardiography and radionuclide cardiography monitoring techniques into anaesthetic practice will enable measurement of left ventricular dimensions, myocardial performance and wall motion. Suggested guidelines for anaesthetic management are presented in Table VI. A combined opiate-oxygen-volatile anaesthetic agent technique will best ensure a hypodynamic circulation with preservation of myocardial oxygenation.(ABSTRACT TRUNCATED AT 400 WORDS)

Two cases of leaking atherosclerotic abdominal aortic aneurysm are presented. The leakage caused fever and leukocytosis, combined with signs of peritoneal irritation. Blood hemoglobin levels were reduced. Both patients were initially treated for sepsis but within hours the cause was identified; both died in the operating theater. The experience of others is reviewed and the mechanism of fever caused by leaking aneurysm is discussed.

There is a growing appreciation of the magnitude of the problem of AAA in all Western countries. The large numbers of subjects needed to answer some of the questions, such as the natural history of small AAAs and risk factor analysis, requires that these studies be carried out by a multicentre group. The advantages of international collaboration, when possible, should ensure more uniform methods and definitions as well as more rapid recruitment of subjects. Granting agencies may find such an approach more attractive, and the results may be more relevant.

The perioperative and long-term survival of patients who undergo resection of abdominal aortic aneurysm is often determined by coexisting cardiac disease. This study evaluates the influence of left ventricular ejection fraction on both perioperative and long-term morbidity and mortality. Preoperative ejection fraction was measured in 104 of 208 patients undergoing elective abdominal aortic aneurysm resection. Nineteen patients were found to have ejection fractions less than 0.35, and this group was compared to 85 patients with ejection fractions greater than 0.35. The two groups did not differ significantly in terms of age, sex, preoperative renal function, or smoking status. The groups were significantly different with respect to the prevalence of prior myocardial infarction (79% of the low ejection fraction group vs 31% of the high ejection fraction group) and symptoms equivalent to New York Heart Association class II or greater (47% of the low ejection fraction group vs 24% of the high ejection fraction group) but not prior myocardial revascularization procedure (42% of the low ejection fraction group vs 31% of the high ejection fraction group). Surgical factors including aneurysm size, duration of aortic cross-clamping, and extent of arterial replacement did not differ significantly between the two groups. The perioperative mortality was not significantly different (low ejection fraction, 5%; high ejection fraction, 2%). The cumulative life-table survival of the two groups was not statistically different. Two patients in the low ejection fraction group died in the follow-up period, yielding a 4-year actuarial survival of 0.74. This is compared to 10 deaths and actuarial survival of 0.63 (p = NS) in the high ejection fraction group. We conclude that patients should not be denied aneurysm resection solely on the basis of left ventricular ejection fraction.

The case of a 64-year-old white man with acquired immunodeficiency syndrome and ruptured abdominal aortic aneurysm infected with Salmonella is presented. Five points related to this case are addressed. It is feared that the vascular surgeon may face patients with acquired immunodeficiency syndrome and abdominal aortic aneurysms infected with Salmonella with increasing frequency in the future. This case raises medical, ethical, and moral questions.
