[Partial anomalous pulmonary venous drainage of the left lung into the innominate vein (author's transl)].

From 5 cases of partial anomalous pulmonary venous drainage of the left lung into the innominate vein, it has been thought of interest to situate this type of venous anomaly among the partial anomalous pulmonary venous drainage classification. It is revealed in 2 different ways. In adults, this malformation sets the problem of the diagnosis of an abnormal chest Xray, without symptom. In children, this vascular abnormality is discovered during the exploration of a congenital cardiopathy which causes the main symptoms. Embryological data are reviewed and statistics of frequency which lead to show that this type of partial anomalous venous drainage is often misunderstood, particularly with regard to anomalous venous drainage of the right lung.

[Arteriography in polyarteritis nodosa. Diagnostic findings and value of repeated examinations (author's transl)].

The results of 18 abdominal arteriographies (general aortography, selective renal, superior mesenteric, and coeliac arteries) in 11 patients with polyarteritis nodosa (P.A.S.), are reported and analyzed. In all tissues, the frequency of the lesions was 66% for micro-anéurisms, 100% for stenoses, and 83% for thromboses. These are seen mainly in the kidney, but isolated lesions may occur in the liver and gastro-intestinal tract. As they vary with time and the area affected, selective contrast studies of the main stems of the abdominal aorta and, in some cases, repeated arteriographic examinations, are necessary.

[Duplication of the digestive tract in adults. 5 cases (author's transl)].

Five cases of duplication of the digestive tract are reported: oesophagus, stomach, duodenum, and colon. These patients were adults, in whom it is rare (5% of cases) to find such duplications. Two types of image are seen on barium meal examination: opacification of a lumen which may be abnormally blind and which can be easily diagnosed if it is short, but is sometimes more difficult to individualize if the duplication is long (colon); or an extrinsic type of compression which is a part of the wall and much more difficult to diagnose. Knowledge of these different types of radiological images in adults should avoid precipitous investigations and orientate possible surgical interventions.

[The collateral circulations of the spermatic veins (author's transl)].

The frequency and appearance of anastomoses between the spermatic veins and the inferior vena cava and portal vein, are analyzed in a series of 171 patients examined by retrograde spermatic phlebography. Spermatocaval anastomoses are divided into those that occur above the scrotum: direct (spermatocaval and iliospermatic) and indirect (perivertebral and ureteric); and those seen at the level of the scrotum (with the scrotal veins, veins of the vas deferens, and those from the contralateral scrotal area). Spermatoportal anastomoses are frequent but difficult to confirm because of the existence of proximal valves. Three cases are also reported which give examples where the spermatic vein played an important part in the collateral circulation (inferior vena cava thrombosis, left renal vein thrombosis, portal hypertension).

[Angiographic abnormalities after punch-biopsy of the liver (author's transl)].

The authors report on 10 cases of complications during punch-biopsy of the liver, an arterio-portal fistula being the one most frequently encountered (8 out of 10 cases). The clinical condition improved in 9 cases out of 10. The authors stress the frequency of arterioportal fistula after punch-biopsy of the liver (60% it arteriography is carried out during the first week). They recall the benign character of these fistulae and their tendency towards spontaneous healing.

[Abnormal partial pulmonary venous return of the left lung in an adult (author's transl)].

The authors report a case of left-sided abnormal partial pulmonary venous return. This abnormality was discovered following weight loss with a strongly positive tuberculin skin test. A plain chest X-ray showed an externally convex opacity filling the aortico-pulmonary space, suggestive of a lymphadenopathy in that area. Pulmonary angiography and selective opacification of the different afferent branches of this abnormal vein defined the territory of drainage of this A.P.V.R.

[Intestinal hemorrhage due to blind loops. 3 cases and review of the literature].

The authors report 3 cases of intestinal bleeding either micro- or macroscopic induced by ulcers in blind loops. The blind loops developed in all 3 cases on side-to-side ileocolic anastomoses. In one of the patients, the ulcers were demonstrated by colonoscopy. The 3 cases reported are quite comparable to the 18 cases found in the world literature. These hemorrhages may become severe by their abundance or repetition, but a cure is easily obtained by resection of the intestinal blind loops and restoration of the continuity by end-to-end anastomosis.

[Radiological anatomy of the spermatic veins. Report of 152 retrograde spermatic phlebographies (author's transl)].

The authors analyse the results of 152 retrograde phlebographic explorations in the investigation of varicocoele: anatomical variations of the right and left spermatic veins (site of arrival, number of venous trunks, existence or not of valvules). They emphasise the importance of anastomoses with other venous systems, not only the inferior vena cava, but also the portal veins. These anastomoses which are essential, explain certain relapses of varicocoele after surgery, and explain the spontaneous portacaval anastomoses which form through the genital veins in certain cases of portal hypertension.

[Radiological aspects of diffuse pulmonary lymphangiomyomatosis (author's transl)].

The authors report on 5 cases of diffuse pulmonary lymphangiomyomatosis. This disease occurs in women during the period of genital activity and usually presents with pulmonary signs (9/10) : dyspnoea, pneumothorax, pleural effusion, and hemoptysis. It is also found in association with renal angiomyolipomas and uterine fibromyolipomas. X-ray films of the lungs show : an interstitial syndrome, gas or fluid pleural effusions, and thoracic distention. None of these signs is constant, but the association of an interstitial syndrome with thoracic distention in a young woman appears to be specific for this affection.
