[Subrenal aortic occlusion].

The juxtarenal aortic occlusion is an infrequent but not exceptional condition determining several problems during the corrective procedure. The incidence of this pathological picture is around 10% of the patients affected by steno-obliterative lesions of the subrenal aorta. The danger of this morbid condition derives mainly from the risks threatening the renal function which sometimes is already endangered before surgical intervention. The operation however implies high additional risks because some surgical procedures require suprarenal aortic clamping and because during the surgical manoeuvres embolization could occur in the lumen of renal arteries. This study analyzes 206 patients who underwent surgical intervention for subrenal aortic occlusion during the last 15 years. 11 patients were operated on in emergency because of lower limbs ischaemia. 4 patients presented a complete thrombosis of an aneurysmatic lesion of the subrenal aorta. The study is aimed at analyzing the renal behaviour in the postoperative period, comparing its functionality with the preoperative parameters. A second aspect which will be considered refers to the type of surgical procedure.

[Protection systems of erythrocytes during intraoperative autotransfusion. Experience with the use of S-adenosyl-L-methionine].

An experiment lasting 2 years in more than 200 patients in single blind conditions (S-Adenosyl-L-Methionine vs placebo) aimed to improve protection of red cells during intraoperative autotransfusion. The two groups are analysed and, on the basis of objective hematochemical data it is concluded that in patients treated with the pharmacological support erythrocyte membrane stability is good.

[Clinical aspects, diagnosis and therapy of thrombosis of an abdominal aortic aneurysm].

In a consecutive series of 640 surgically treated abdominal aortic aneurysms, 4 patients affected by thrombosis of the abdominal aortic aneurysm were observed. All aneurysms were five centimeters in diameter or smaller and all the patients complained of chronic claudication. In spite of the old opinion that considered abdominal aneurysmal thrombosis an useful event, we believe that the angiographic and clinical picture of juxta-renal aortic occlusion points to surgical treatment.

[Aneurysm of the popliteal artery: clinical aspects and therapy].

Experience of the operative treatment of 45 popliteal aneurysms in 41 patients is reported. The importance of immediate surgical reconstruction whenever a popliteal artery aneurysm has been detected is stressed. In fact, the patency rate of the arterial substitutes which are utilised in the reconstructive technique, and therefore the fate of the affected limbs, is chiefly based on the presence of a sufficient run off. Ischaemic complication due to peripheral embolization or sudden thrombosis of the aneurysmatic sac is very often followed by the irreversible closure not only of the tibioperoneal arteries but also of most collateral vessels.

[Diagnostic methods in aneurysms of the abdominal aorta].

Various diagnostic procedures are currently used for the correct diagnosis of abdominal aortic aneurysms. The different procedures are selected in order to detect the morphology of the lesion (craniocaudal extension), associated steno-obliterative lesions and, on the basis of clinical findings, presence of possible aneurysmatic ruptures. In this paper the limits and advantages of different diagnostic procedures are compared and the use of these various techniques discussed.

[Diagnostic considerations in 104 cases of aneurysm of the subrenal abdominal aorta surgically treated in 1987].

A series of 104 patients observed and surgically treated for abdominal aortic aneurysms, in the General and Cardiovascular Surgery Department of Milan University during 1987 in analysed. Particular attention is paid to the diagnostic procedures especially in those cases when the condition was found by chance during clinical examinations requested for different pathologies.

[Traumatic lesions of the popliteal artery].

Even today, traumatic lesions of the popliteal artery mean in a large percentage of cases (from 25% to 45% according to recent reports) loss of the extremity, notwithstanding the considerable advances made by reconstructive vascular surgery. The most important series are reported in relation to events of war in the past (Korea, Vietnam) and more recently. As for lesions in everyday life, the highest percentage is the result of road and particularly motorbike accidents. A review of the most recent literature shows that the prognosis for lesions of the proximal and middle segment of the popliteal artery is greatly improved while in lesions of the distal portion and particularly the trifurcation, the percentage of failure with consequent amputation is still very high (from 30% to 40% of cases). Here personal experience of 6 cases of lesions of the popliteal artery due to osteovascular trauma observed in the past two years is reported, the diagnostic procedures and therapeutic treatment adopted being discussed.

[A rare case of aneurysm of the superficial femoral artery with dysplasic etiology].

The most frequent localisation of fibrous dysplasia of the arteries is at the renal arteries. Other localisations are rarer and those at the femoral as in the case described are exceptional. The case was observed in a 21-year-old woman who, in the absence of any previous traumatism and septic state, noticed the onset of a pulsating tumefaction at thigh level. Echography and arteriography showed the tumefaction to be an aneurysm of a collateral of the superficial femoral artery at the lower IIIrd of the thigh with the dimensions of a pigeon's egg. The aneurysm was successfully removed without the need for grafts and subsequent histological examination showed it was secondary to fibrous dysplasia. The rarity of such a clinical case is stressed.

[Treatment of ischemia in late thrombosis after aorto-iliaco-femoral reconstructions].

Late thrombosis of inserted prosthetic grafts for arterial reconstructive surgery is one of the most frequent late complication. Its incidence is influenced by many factors: hemodynamic conditions, quality of run-in and run-off, technical aspects of the primary repair. Progressive arteriosclerosis in femoral vessels was the cause of graft limb thrombosis in most instances. When graft occlusion does occur, there is, in a majority of patients, an immediate return of ischemia which often is severe and redo-operation is indicated to restore circulation. A new angiogram is mandatory, especially for the recognition of the inflow to the central anastomosis and for the evaluation of the distal run-off. Several surgical techniques are in use for redo-operation (graft thrombectomy with or without graft prolongation, partial or total replacement of the prosthesis, reconstruction by an extra-anatomical by-pass). Very important is the role of the deep femoral artery: in patients with a multi-level occlusive disease a patent deep femoral artery most often provides an effective inflow repair with a combined use of profundaplasty and lumbar sympathectomy. In this report of 188 late thrombosis, in a twenty year experience, at the Department of General and Cardiovascular Surgery, University of Milan, we made a redo-operation in 83% of the cases, according our preference in surgical procedures, to the partial substitution of the prosthesis with large profundaplasty. An associated lumbar sympathectomy was performed in 25% of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Selective hypogastric arteriography in the diagnosis of vascular impotence].

Clinical employment of selective hypogastric arteriography has been instrumental in the detection of stenosing and obliterating lesions of the pudendal arteries and their penile branches capable of giving rise to impotentia erigendi as the sole symptom. Differentiation of psychogenic and vascular impotence is now possible through non-invasive instrumental examinations such as the nocturnal penile tumescence test, and Doppler ultrasonography of the penile arteries. Arteriography to clinch the diagnosis was only employed when a suspicion was aroused by these two examinations. An account is given of technique employed for selective hypogastric arteriography and the angiographic results obtained.
