[Portal vein: echographic anatomy].

The principal descriptions of the portal vein are mainly on the results of the dissections of the corpses. The aim of the work was to determine the usual sizes of the portal vein on the alive subject by echography. From the same machine, 3 ultrasonographers studied the anatomy of the portal vein of the volunteers according to a standardized methodology. The study was about 60 old people from 11 to 82 years old, whom 31 were males (51.7%) and 29 females (48.3%). The transverse diameter of the portal vein, originally varied between 8 and 10 mms un 57.9% of cases. The average was 9.05 mms +/- 2.82 and the extremes varied from 5 to 16 mm. The transverse diameter of the portal vein, at the end varied between 8 and 10 mms. The average was 9.16 mms +/- 2.58 and the extremes varied between 6 and 16 mms. In 29.8% of cases, the length of the portal vein was between 61 and 70 mms and in 8.8% between 81 and 100 mms. The average was 58.0 +/- 22.3 mms. Before its entry into the liver, the portal vein is divided into 3 branches in 2 cases (3.3%). The study showed a significant change of the length of the portal vein according the age and sex.

[Anatomical variations of the brachial plexus].

Important variations exist in the brachial plexus (Kaufmann, Cunningham, Kerr, Lee). Perivascular techniques of brachial plexus block used sometimes use important quantities of anaesthesia product. It seems that certain surgical treatment failures of brachial plexus lesions are related to the brachial plexus variations (Bonnel). Our aim is to study the brachial plexus variations and its relations from the cervical region to brachial region. We dissected twenty-three brachial plexus (13 women and 10 men, fresh or injected by formalin). We studied the brachial plexus anatomic variations and its relations. We found the anatomic variations at the level of different parts of brachial plexus: Trunk: 8 cases (34.8%); Terminal branch: 8 cases (34.8%); brachial plexus tract: 1 case (4.3%); collateral branch: 1 case (4.3%); in 5 cases we didn't find any abnormalities. Some studies show the frequency of 4th cervical root (C4) participation in brachial plexus. Kerr found 65.9%. It was 30.4% of C4 participation in brachial plexus in our series. Among the 8 cases of terminal branch variations in our series, two (8.7%) musculocutaneous was low source. The brachial plexus variations could fail the brachial plexus loco-regional anaesthesia. In the surgical treatment of brachial plexus lesions, the surgeon must know brachial plexus anatomical variations perfectly.

[Human "pancreatic" bladder. Two case reports].

The aim of this study is to report two similar cases with an "accessory biliary duct" confluent to the main pancreatic duct. There was pancreatic juice inside the "gallbladder". There was no connection between "accessory biliary duct" and intra or extrahepatic biliary ducts. This anomalous junction of the "cystic duct" and the main pancreatic duct may be explained by embryology. These two cases could be the first human "pancreatic" bladders reported.

[Differed autologous blood transfusion in the "G" point hospital in Bamako. Prospective study apropos of 40 cases].

With a sample of 40 patients, the authors conducted a prospective case-control study on the feasibility of differed autologous blood transfusion at Point "G" National Hospital in Bamako, Mali. The method has been accepted by all the patients. No clinical nor biological trouble has been reported by the patients themselves. The authors recommend the use of autologous blood transfusion by other hospital units and the development of regulations governing its implementation.

[Ectopic spleens. About a spleen of the right iliac fossa (author's transl)].

A rare case of the presence of the spleen in the right iliac fossa is reported. The frequency and signs of ectopic and supernumerary spleens are described, the latter requiring differentiation from peritoneal splenosis. An embryological explanation for the presence of the spleen in the right iliac fossa is suggested.
