Indications for surgical treatment of cerebrovascular insufficiency.

197 cases of patients with CVI, subjected to surgery by carotid endarterectomy, are examined. The results were nearly always good and hence the technique is recommended. Particular interest is attached to the risk connected with carotid clamping, through intraoperative study of CBF with 133Xe, such a risk is practically removed.

Stress MR imaging for evaluation of popliteal artery entrapment.

The popliteal artery entrapment (PAE) syndrome has been recognized as a cause of arterial occlusion in young people. It is the result of an anomaly of the relationship between the popliteal artery and the gastrocnemius muscle. Eight young health volunteers (16 legs) and six patients (10 legs) with suspected PAE underwent magnetic resonance (MR) imaging. Gradient-echo images were obtained in axial planes with the leg at rest and during active plantar flexion against resistance. Imaging at rest allowed identification of PAE signs in only one leg, which had an anomalous medial course of the popliteal artery. In the other cases, only the stress technique was able to show signal loss in the popliteal artery due to muscular compression (two legs) or the presence of accessory muscle slip around the vessel (two legs), as confirmed at surgery. MR imaging is therefore a useful technique for the diagnosis of PAE because of its capability of combining information obtainable with other modalities.

Popliteal artery entrapment: MR findings.

A 35-year-old woman with a history of claudication was examined by means of echodoppler, angiography, and MR imaging using gradient rephased sequences, performed at rest and during stress. Magnetic resonance imaging allowed the evaluation of the relationships between the gastrocnemius muscle and the popliteal artery at rest and the evidence of the occlusion during stress. This combined morphological and functional evaluation makes MR a procedure of choice for assessment of young adults with intermittent claudication.

Clinical and therapeutical evaluation of inflammatory aneurysms of the abdominal aorta.

Unexpected anatomical and clinical features of abdominal aortic aneurysm (AAA) may be encountered by the vascular surgeon creating technical problems that increase the normally low mortality rates of this affection. One such variant is the so called inflammatory aneurysm (IA) as a characteristic fibrosis involving the arterial wall and thus surrounding structure scan be observed. In our series of 525 patients affected by AAA the incidence of IA was about 4% (19 cases). Two groups of patients were considered: group A, including all the atherosclerotic patients, and group B 19 patients affected by IA. The latter group referred to a typical painful symptomatology in 84% of the cases: this element is of interest as only 20% of the cases of group A complained of pain. No other significant clinical or laboratory data were recorded which could allow the surgeon to perform a pre-operative differential diagnosis. In all 19 cases that underwent surgical treatment there was a 2-3 cm thick aneurysmal wall with a shiny white surface adhering to the IV portion of the duodenum, vena cava and iliac vessels and in some cases to the ureters. Histological examination of specimens of the aortic wall showed evident signs of atherosclerosis of the media and marked fibrotic thickening of the adventitia with the presence of lymphocyte aggregates: a sign of chronic inflammation. As what concerns indications and surgical treatment, there are no substantial differences. Pre-operative differential diagnosis can be made with CAT scan and ultrasound and the usual operative manoeuvres of aneurysmorrhaphy should be modified.
