[Percutaneous angioplasty of the renal arteries. Long-term results of 222 operations].

Objectives: Determine the relative role of percutaneous angioplasty of the renal arteries in the treatment of renovascular hypertension.

Methods: From September 1984 to June 1993, we performed 222 angioplasties in 196 patients with renovascular hypertension. There were 186 atheromatous stenoses of the renal arteries and 36 fibromuscular dysplasias.

[Results of endoprostheses in the iliac arteries; an experience apropos of 47 implantations].

Obstruction or stenosis of the iliac artery was treated by placement of an endoprothesis in 41 patients. A total of 47 lesions was treated. 26 patients had poor results of balloon angioplasty including residual stenosis (7 cases), restenosis post angioplasty (7 cases), and dissection (12 cases).

Postoperative pseudoaneurysm of ascending aorta: role of ultrafast computed tomography imaging.

A 34-year-old woman, who had undergone a thoracic aortic aneurysmectomy and replacement with a prosthetic tube graft several months previously, presented with a pseudoaneurysm arising from the proximal anastomotic site. This pseudoaneurysm was studied with contrast-enhanced ultrasfast computed tomography. The exact location of the suture dehiscence was located by the presence of a contrast jet flow through the aortic wall.

[Atrophic polychondritis presenting as multiple arterial stenosis. Report of a case].

A case of multiple arterial stenosis is reported in a pattern with atrophic polychondritis. The disease was diagnosed retrospectively nine years after the first vascular signs on the basis of clinical course. Atrophic polychondritis is a rare connective tissue disease with characteristic chondritis.

[Pleural thymoma. Apropos of a case and review of the literature].

The authors report a case of pleural tumor discovered in case of thoracic pain in a 72 year old woman. This lesion, discovered on chest X-Ray, developed in the left costo-vertebral groove and was seen as a homogeneous opacity, multilobate, well-defined. CT confirmed the pleural origin, showed a thickening of posterior pleural, a polylobate tumor well-defined on its lung side, non-invasive and of tissue density.

[Modern imaging in radioanatomic study of the shoulder].

The authors describe the most appropriate imaging technique or techniques for assessment of each anatomical structure in the shoulder: the head of the humerus, socket, acromion, joint space, labrum, musculotendinous structures of the supraspinatus, subscapularis and long biceps muscles. The techniques used are the most useful view of standard X-rays, as well as arthropathy, CT scan, arthroscan, ultrasonography and MRI. This is a preliminary study to assessment of shoulder lesions.

Thphenidate.

Plasma cyclic-AMP responses to adrenergic agonists are due to stimulation of the peripheral beta-adrenergic receptor. Mood responses to stimulants are thought to be due to actions leading to stimulation of central catecholamine receptors. To determine if a peripheral measure of receptor sensitivity could predict central mood effects of stimulants, the plasma cyclic-AMP response and the mood response to intravenous methylphenidate were determined simultaneously in 13 subjects.
