Nineteen year experience on the treatment of aneurysms of the abdominal aorta: a survey of 832 consecutive cases.

832 patients with abdominal aortic aneurysm were admitted to our Hospital, at the University of Milan, from 1965 to 1983. 238 patients were operated on as an emergency for rupture of the aneurysm while 541 underwent elective surgery. The overall postoperative mortality was 7% for the patients operated on electively and 54.3% for the ruptured aneurysm operated on as an emergency.

Occlusive arterial disease in young patients.

All the young patients (under 40 years) affected by occlusive arterial disease observed at the Istituto di Clinica Chirurgica II, University of Milan, during the last eleven years have been reviewed. About one third of these patients is affected by a form of arteritis; the others demonstrate the typical pattern of early atherosclerosis or an indeterminate condition which may represent an atherosclerotic complication superimposed on a basic arteritic lesion. The available therapeutic procedures are examined. They show that atherosclerotic disease more frequently permits a surgical reconstruction. The average rate of amputation is about the same in the two considered forms, ranging close to 7-8%. The 10 year follow up of these groups of young patients allowed us to analyze the rate of progression and evolution of these morbid conditions and the influence of the most important risk factors.

Influence of the rupture site of abdominal aortic aneurysms with regard to postoperative survival rate.

This study presents an analysis of the influence of the site of rupture of abdominal aortic aneurysms on the postoperative survival rate. A series of 226 patients, who underwent emergency operations for ruptured aneurysms, is examined. The three most important methods of rupture are: (1) Retroperitoneal rupture: this type is associated with a very high mortality (52.8% in our experience), which reaches almost 75% when the posterior parietal peritoneum tears and massive intraperitoneal bleeding occurs. This mortality is related to the amount of blood loss, hypovolemic shock, the number of transfused blood units and, especially, to increasing renal insufficiency. (2) Rupture into the inferior vena cava: in this event the mortality rate it less severe (38.4% in our experience) and it is mostly related to the occurrence of an high output cardiac failure, as well as to oliguria or anuria following renal venous hypertension. (3) Enteric rupture: this is, in our experience, the most uncommon event. It carries a high mortality rate (50%). The copious bleeding, which is unrestricted in hollow organs, explains the dangerous hypovolemic shock, while massive blood reabsorption from the enteric tract leads to a renal insufficiency.

Critical evaluation of limb salvage concept and indication for infrapopliteal reconstructive surgery.

A large number of surgical procedures aimed at revascularizing the popliteal and infrapopliteal arteries has been reported in patients affected by rest pain or gangrene of the extremities as well as intermittent claudication. In consideration of the high incidence of early and late unsuccessful results following this type of surgery as reported in the literature, we believe that peripheral reconstructions should be restricted to those patients presenting a clinical picture of such severity that major amputation is unavoidable in the short run. In these patients our choice of the appropriate surgical procedure is strictly related to the patency or not of the popliteal artery. The role of the above knee femoropopliteal bypass is discussed. A series of patients that we have operated upon according to these criteria is analyzed. The low number of cases in our group of patients and the high rate of postoperative failures reflect our policy on this matter.

Metabolic factors influencing indications and results of reconstructive surgery in peripheral atherosclerosis.

The incidence of risk factors at the time of operation and in the late postoperative course was evaluated in a series of patients operated upon for reconstruction of the aorto-iliac and femoro-popliteal tracts. The data reported seem to indicate a direct correlation between the long term patency rates of the arterial reconstructions and the incidence of the risk factors.

[Risk factors for arteriosclerosis and diet of surgical patients. 10 years of outpatient activity].

The follow-up of arteriopathic subjects who have already been hospitalized (abdominal-peripheral vascular district 79% of patient and supra-aortic branch district 21%) has been carried out for around 10 years using an out-patient regime at the Institute of General and Cardiovascular Surgery of Milan. During outpatient visit the main risk factors for arteriosclerosis are routinely checked and treated if required; among the various therapies for metabolic control particular emphasis is placed on diet since its influence on the metabolism is well known, above all in the long term. The efficacy of this treatment has been evaluated by evaluating blood chemical changes (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, VLDL and glycemia) in a group of patients who followed the diet in comparison to a group which did not. The results obtained show that in dieting patients there was a statistically significant decrease in blood values for total cholesterol, LDL cholesterol, triglycerides and VLDL, together with a decrement, which failed to reach statistical significance, in glycemia and HDL cholesterol. In non-dieting patients it was found that all parameters increased but that this was only statistically significant for total cholesterol and HDL cholesterol. The control of risk factors for arteriosclerosis through diet therapy therefore appears to be satisfactory even for secondary prevention in surgical arteriopathic subjects. It is important to underline that these results were not obtained under conditions of clinical research but in the reality of day-to-day clinical and therapeutic activity whose efficacy is vitally important for scientific health.
