New knowledge on arterial blood supply of the 3rd and 4th parts of theduodenum. Injection of the digestive arterial system in 15 adult subjects allows the study of the blood supply of the 3rd and 4th parts of the duodenum. Although the duodeno-pancreatic arches are constantly found, the authors showed that the branches to the duodenum have a variable layout. On the right of the superior mesenteric artery, the distribution of the branches is always regular on both sides of the 3rd part of the duodenum. On the other hand, on the left of this artery, there is sometimes a vascular hiatus which may extend to the duodeno-jejunal angle. Although in 60 per cent of the cases, this part of the duodenum is well supplied with blood on both surfaces, in 40 per cent of the cases on the other hand, there exists an avascular area on both sides. This lay-out is not favorable for division and anastomosis of this segment of the digestive tract.

[Study of anastomoses between the left renal vein and the internal vertebral plexus].

Anastomosis between the left renal vein and the rachidian plexus exists in about 80% of the cases (16 cases out of 20); they are important in 25% of the cases (5 cases) ; their origin is constant ; their ending has a high frequency for the rachidian plexus of the intervertebral foramen L1-L2. These anastomoses are of great importance : as they are the only renal circulation's safety device in seven of our cases : their hypertrophy in some pathological cases can explain some neurological clinical pictures of compression, reversible after the ligature of the hypertrophic anastomotic veins.

[Study of the vascular density of tissues surrounding the right recurrent nerve (apropos of 56 cases)].

Study of 56 cases. The right recurrent nerve is more easily found near its origin, below the crossing with the inferior thyroidal artery. Since the vascular density of the adjacent tissue is less important, the dissection is easier and less haemorrhagic.

[Vascularization of the transverse colon].

Results of 21 injections of the transverse colon with coloured latex. The superior and inferior mesenteric arteries are separately injected. Dissections allowed the study of the topography and width of the colic transverse vessels. Collateral circulation is also described. A middle colic artery is present in 85% of the cases. The length of transverse colon vascularized by each arterial system is related with accuracy to the number of arcades issued from each system. The superior mesenteric artery prevails in the blood supply of the transverse colon (70% of its length).

[New acquisitions on the arterial vascularization of the 3d and 4th portions of the duodenum. Surgical applications].

The authors studied the blood supply of the 3rd and 4th parts of the duodenum in 15 adult subjects. Although the duodeno-pancreatic arches are constantly found, the branches to the duodenum have a variable lay-out. On the right, the superior mesenteric artery, the distribution of which is always regular on both sides of the 3rd part of the duodenum. On the other hand, on the left, the superior mesenteric artery, there is sometimes a vascular hiatus which may extend to the duodeno-jejunal angle. Although in 60 p. cent of cases this part of the duodenum is well supplied with blood on both surfaces, in 40 p. cent of cases on the other hand, there exists an avascular area on both sides. This lay-out is not favourable for division and anastomsis of this segment of the digestive tract.

[The blood supply of the semitendinosus, gracilis and sartorius muscles and surgical applications (author's transl)].

The vascular pedicles of the semitendinosus, gracilis and sartorius muscles were identified by the authors. Although devascularisation of the tendons is of no importance in plastic operations, any technic using the fleshy part of these muscles should take care to preserve the blood supply. It is therefore important to know their anatomy.

[Does the phrenico-gastric ligament exist?].

On thirty cadaveric dissections, we studied the so-called "phreno-gastric" ligament. In fact, it appears that there is an adhesion between the fundus and the posterior wall in only 60 % of the cases. This adhesion is always very loose, easily cleaved and in no case is there a real fibrous suspensory ligament. Moreover, in 40 % of the cases, the posterior surface of the fundus is entirely covered by peritoneum and is free in the bursa omentalis. In that case, the posterior surface of the stomach is connected with the diaphragm by a very short meso extending on the right to the meso esophagus and on the left to the gastrosplenic ligament.

[Anatomic variation of the aortic coronary openings (apropos of 80 dissections)].

A series of 80 heart dissections, compared with a survey of the literature shows that:--both coronary ostia are usually in the right anterior and in the left posterior position, in the commissural plane, at the level of the corresponding sinus of Valsalva (the left one being often superior in size to the right one).--anatomic variations of the coronary ostia (especially variations of the left coronary ostium) may be summed up into 3 patterns: Variations in number : sometimes, there is only one aortic coronary ostium, usually owing to a left coronary artery originating from the pulmonary artery; a common aortic ostium for a single coronary artery is not frequent. Multiple ostia are the most common variations : an accessory artery may arise from a separate ostium (often the "third coronary artery" from the right aortic sinus; sometimes the anterior descending and the circumflex arteries may originate from separated orifices). Variations in origin remain few, affecting most often the left ostium. Variations in size reflect the corresponding coronary plexus preponderance.

[Anatomic variations of the common trunk of the left coronary artery (apropos of 80 dissections)].

An anatomic study of the main left coronary artery is reported : important anatomic variations may occur:--sometimes, the main left coronary artery is missing (1 % of the cases),--its origin may be unusual (from the pulmonary artery),--its average length is 11 mm; but, it may be longer (35 mm) and sometimes very short (less than 8 mm in 15 per cent of the cases) : this last aspect has to be taken in account by the surgeon during aortic valve surgery if a coronary perfusion has been decided.--At last, its division into two branches (anterior descending and left circumflex) is the most usual (65 or 70 per cent of the cases). A third branch of division may exist (diagonal or lateral branch) in about 20 to 30 per cent of the cases. The left coronary artery may also divide into four (or even five) branches in 5 to 10 per cent of the cases.
