The authors report their experience in the management of a rare case of bilateral popliteal artery entrapment syndrome occurred to their observation. This unusual pathological entity, arising mostly in young subjects and unilaterally, in this case was bilateral and developed in a 51 years old patient. The clinical case is fully documented by multiple Echo-Doppler and arteriographic examinations which clearly demonstrate the peculiar characteristics of the disease. Finally the patient received a two stage surgical treatment with a good global result. The Authors stress the importance of a correct diagnostic approach to this unusual disease to avoid the possibility to misdiagnose it.

[Solitary ulcer of the rectum. Description of a case].

A case of solitary rectal ulcer is presented. Different views on the pathogenesis are discussed. Symptoms were nonspecific: anal pain, rectal tenesmus and bleeding. On sigmoidoscopy, the lesion has a characteristic appearance, but the definitive diagnosis of benignity must depend upon the recognition of specific histopathologic features in rectal biopsy specimens from ulcer margins. In this case, the surgical treatment was satisfactory, but frequently neither medical nor surgical treatment achieve relief of symptoms or healing of the lesion.

[Evaluation of pre- and postoperative cerebral hemodynamics in extracranial carotid surgery using transcranial Doppler. Preliminary note].

The Authors report their preliminary experiences concerning the use of transcranial Doppler (TCD) in the pre- and postoperative monitoring of extracranial carotid surgery. TCD is a non invasive method of investigation able to give informations about the distribution of cerebral blood flow and about the mechanisms of compensation of Willis' circle. Furthermore, TCD showed itself to be very useful in the postoperative qualitative evaluation of surgery, pointing out, as a general rule, an increased flow in the middle cerebral artery after thromboendarterectomy of internal carotid artery. This haemodynamic modification, if present, is perceptible since the immediate postoperative period and becomes more evident and definitely stable at a distance of 20-30 days after operation, likewise the definitive stabilization of Willis' circle's haemodynamics.

Renovascular hypertension: a non-invasive Duplex scanning screening.

A Duplex-Scanner was used to screen 62 patients with severe hypertension, queried renovascular. Ten results were technically unsatisfactory and in the remaining 52 highlighted flow alterations in the renal arteries of 29 patients were found. Control angiographies confirmed renal artery stenosis in 27 cases. Comparative statistical analyses proved the test to be both highly sensitive and specific, considering other screening methods currently used in diagnosing renovascular hypertension--which include endovenous digital subtraction angiography. Results confirmed the Duplex-Scanner as a reliable renovascular hypertension screener as well as being a non-invasive method with no potentially toxic effects.
