Two rare anomalies of the left renal vein.

Two uncommon anatomical variations of the left renal vein were found on dissected specimens: a circumaortic venous ring and a retro-aortic bifid left renal vein. The first anomaly results from a persistence of the embryonic renal venous collar. The second one would be related to a particular pattern of left inferior vena cava. Both abnormalities have to be known for they may be undetected or be misleading in imaging. Other clinical implications are also considered.

Celiac-bimesenteric trunk: anatomic and radiologic description--case report.

The authors report the case of a 39-year-old man with a common origin of three arteries-the celiac, superior mesenteric, and inferior mesenteric arteries-that has not been described previously in the literature, to their knowledge. This variant, which they call the celiac-bimesenteric trunk, is documented with a selective angiogram, and an embryologic explanation is offered.

[Anatomic variability and congenital anomalies of the gallbladder: ultrasonographic study of 1823 patients].

The authors report the results from the ultrasonographic exploration of the gallbladder performed on 1823 patients. They found morphologic variations and abnormalities in more than 33% of gallbladders, topographic ones in about 3.5% of observations and only 3 cases of real duplication of the gallbladder. Folds and septa may induce traps during echographic examination.

Thoracoscopic dissection of the esophagus in human cadavers.

A technique for thoracoscopic dissection of the esophagus is described which gives a large and magnified view of the pleural cavity, the mediastinum, and the esophagus. This technique was developed on human cadavers which gives excellent technical resources for learning and practicing endoscopic surgical anatomy of the esophagus. It avoids the need to change the position of the patient to perform a total thoracoabdominal esophagectomy via a triple surgical approach.

[Value of x-ray computed tomography in evaluating the operability of esophageal cancer. Results of a prospective study].

The authors report their results of a prospective double-blind study of 35 patients with squamous cell carcinoma of the esophagus conducted between February 1987 and February 1988. As all the patients were operated upon, we were able to define diagnostic accuracy (DA) of CT in determining the upper pole of the tumour, position of the tumour, invasion of trachea and bronchi, aorta, left auricle, vertebral column, pleura, pericardium and also abdominal invasion or thoracic lymph node. CT scanning slightly improved pre-operative evaluation of resectability of tumours when compared with routine barium swallow, abdominal US and bronchoscopy. It is not of great help for tumours smaller than 5 cm. CT scanning is particularly useful in evaluation of response to pre-operative chemotherapy.

The venous hilum of the testis and epididymis: anatomic aspect.

The venous return from the testis is effected by 3 venous pathways: the pampiniform plexus gathrs the centripetal and centrifugal paths of the testis with the marginal vein of the epididymis; the deferential vein accompanies the ductus deferens; and the cremasteric vein travels more superficially between the internal and external spermatic fasciae on its way to the inferior epigastric vein. At the caudal pole of the testicle these different pathways form such close connections as to constitute a real vascular junction.

Radiologic anatomy of duplication of the inferior vena cava: a trap in abdominal imaging. A report of 8 cases.

Eight cases of duplication of the inferior vena cava are reported. Three of these bear witness to the errors of interpretation that may be committed when the anomaly is not initially detected in the ultrasonographic transverse sections and when no preliminary phlebography is available. Two other cases illustrate the influence of this duplication on the choice of the prophylactic surgical treatment of pulmonary embolism. The last clinical observation indicates the need to puncture both the femoral veins when performing iliocaval phlebography. Finally, two observations on the cadaver help to clarify the imaging appearances of this anomaly. The report concludes with a review of the classical anatomic and pathogenic concepts and a short discussion of the practical problems posed by duplication of the inferior vena cava.

[Echographic aspects of biliary lithiasis and its complications].

Ultrasonic appearances of various types of gallbladder stones are described and findings on ultrasonic imaging of the main complications of biliary lithiasis analyzed. New possibilities for examination of the principal biliary pathway are being opened up by progress in improving resolution of the ultrasonoscope and by advances in knowledge of ultrasonic anatomy of the biliary tracts.

[Morphologic and biometric data on the constitution of the brachial plexus in man].

The authors relate the results of the examination of 172 human brachial plexuses from 89 leukoderma subjects native from the Parisian area. The origin of the plexus, with a participation of the fourth cervical nerve root in 41 p.c. of the plexuses, and its distribution, with three primary trunks in 90 p.c. of the plexuses were correctly described by classic authors. The secondary ventro medial trunk receives fibers from the middle primary trunk in 10 p.c. of the plexuses. The biometric study shows that the seventh cervical root is the largest on both sides and that secondary trunks are longer than the primary.

[Biometric aspects of hyoid mechanics in man].

The motionless position and the movements of the human hyoïd bone are defined by angular and linear measures, with regard to the basis of the skull and the horizontal palatine level. It appears that the hyoïd mechanic, which is at best expressed during swallowing and speech articulation, is mainly dependent on styloid suspension, that allows sinusoïdal trajectories.

[Radio-anatomic data concerning the hyoid bone and its dynamics].

The study of the Human hyoid bone made from anatomic sections, X-ray pictures and radiocinema shows its variable positions during speech articulation, which vary according to the kind of phonema--from single horizontal or vertical translation to sinusoidal movements allowed by the stylohoid suspension. The hyoid bone plays a role in speech articulation and may have been a factor in its apparition.
