[The value of MRI in popliteal entrapment syndrome]. / Intérêt de l'IRM dans le syndrome de l'artère poplitée piégée.

The popliteal artery entrapment syndrome (PAES) is a frequent disease of especially young patients, often following a muscular exertion. To avoid the complications, the diagnosis must rapidly be done. According to this report of a 12 year old child, we think that magnetic resonance imaging (MRI) is very accurate to diagnose the abnormalities of the popliteal artery course, the muscular hypertrophies and can relieve of more invasive procedures such as the arteriography associated with known morbidity in young patients.

[Palliative urinary diversion in inoperable pelvic tumors]. / La dérivation urinaire palliative dans les tumeurs pelviennes dépassées.

The problem raised is that of the legitimacy of palliative urinary derivation in the malignant tumours of the pelvis beyond any therapeutic possibility. Between 1980 and 1985, 49 patients were referred to the department of Urology of Rennes for cutaneous ureterostomy type. 39 records were suitable for review. Bilateral ureteric obstruction in the course of carcinomas of the pelvis, regardless of the origin, is uncommon bearing in mind the prevalence of such pathology and notably in women. Recent techniques (J catheter, per-cutaneous nephrostomy) have simplified the surgical procedure of urinary bypass. They do not fundamentally change the incisions and are not always applicable. Use of the J catheter may be prevented by the impossibility of intubating the ureter or when the bladder is unusable as a reservoir, whilst the use of percutaneous nephrostomy is hazardous or possibly even insufficient to dry the perineum when there is a malignant vesicovaginal fistula. This study involved evaluation of 39 patients who underwent uni or bilateral terminal cutaneous ureterostomy, any other technique having proved to be undesirable. The mean survival of the patients was 225 days and its quality as good or satisfactory in only 25% of cases. The implantation of epidural morphine reservoirs may improve the quality of survival of these patients by suppressing pain which up to now has been an absolute contraindication to an upper cutaneous derivation procedure.

[Lateral ventral or Spiegel's line hernia. Apropos of 8 new cases]. / Les hernies ventrales latérales ou de la ligne de Spiegel. A propos de 8 nouvelles observations.

Eight cases of lateral ventral hernia, or the so-called hernia of the line of Spiegel, included 2 serious cases complicated by a pyostercoral phlegmon. The principal anatomic, clinical and therapeutic features of these hernias are discussed, with emphasis of the probable underestimation of this affection and the value of parietal ultrasound imaging for its early diagnosis in patients with abdominal pain unexplained by a deep visceral lesion.
