[Biometry of the inferior vena cava (subrenal segment): dissection of 100 recently deceased subjects].
The vena cava inferior in its infra-renal part is a selective place to set on anti-thrombosis devices. The biometry of 100 fresh, adult cadavers interested the useful and real lengths, the diameters on several levels and on the corresponding part of the aorta, the end of the iliac venae and the origin of the iliac arteriae. The useful length of the vena cava inferior is 96 mm in mean, and its real diameter is 17 mm, on the middle of the infra-renal part.

Review Case Reports[Isolated azygos continuation of the inferior vena cava. (Absence of the retrohepatic segment of the inferior vena cava)].
The isolated azygos continuation of the inferior vena cave is a very rare variation of this organ. It is accompanied by the absence of the retrohepatic segment of the vena cava with two new observations, the literature is revised and the origin discussed.

[The pericardium of the newborn infant. Anatomic and radio-anatomic study with the view toward better positioning central catheters in the superior vena cava].
The aim of this study was to define Anatomics relationships of pericardium and veine cavae superius in newborn. In clinical experience the possibility of acute "hydropericardium" accidents in newborn with central venous parenteral nutrition, shows that the catheter must be positioned above the pericardium reflexion line. In this study, this line appears clearly above T2 Pevel.

[Development of the dorsal branches of the spinal nerves during the true embryonic period].
A study of the Carnegie collection of human embryos has enabled the author to establish the sequence of events in the development of the dorsal rami of the spinal nerves. As the ventral rami enter the muscle anlagen and the rami communicantes appear at stage 14, it is sometimes possible to note the anlage of a dorsal ramus in the cervical region. At stage 15, the dorsal ramus is well distinguished, but seems to correspond with only its lateral division; indeed, the medial division is evident only in the next stage. ⋯ At stage 21, however, fibres of the lateral ramus pass beyond the b=fascia and reach the cutaneous vascular layer, whereas fibres of the medial ramus have not yet gained the fascia. At the end of the embryonic period proper (stage 23), the cutaneous fibres of the lateral branch begin to cling to the corium (dermis), but the medial fibres seem merely to pass through the vascular layer without any attachment to the chorion. In summary, it can be stated that: 1) the dorsal rami of the spinal nerves are a little late in comparison with the lateral ones, 2) their lateral branches precede the medial ones, 3) they develop steadily from the depth to the surface, from the cervical to the caudal region, and from the lateral to the medial area of the dorsal skin.
