[Massive pulmonary embolism due to post-traumatic pseudo-aneurysm due to rupture of the left hepatic artery, revealed by dissecting aneurysm below the capsule of the right lobe of the liver (author's transl)].

We report a case of trauma of the left lobe of the liver causing left centro-hepatic contusion (stage III) revealed by infective jaundice. Secondarily, the appearance of a right subcapsular hematoma corrected the diagnosis, permitting the authors to proceed to angiographic exploration and consider operation on the right side, but the patient had a massive pulmonary embolism. This case recalls the diagnostic difficulties soon after a contusion, the diffusion of a hematoma under pressure from left to right, then from the liver towards the hepatic venous system, the risk of pulmonary embolism, from an aneurysm of the hepatic artery.

[Intermittent postoperative gastric aspiration. New equipment (author's transl)].

Gastric suction is prescribed routinely by some, even though it is responsible for complications which are sometimes extremely serious, such as haemorrhagic gastritis or even perforation. It is indicated in all cases of postoperative gastric ileus or of stenosis causing marked dilatation of the stomach. However, experience would tend to show that in addition to problems immediately secondary to the presence of the tube in the gastric lumen, it sometimes leads to a false sense of security since the apertures of the tube tend to suck in the mucosa, giving rise to a suction-like effect whilst the stomach remains full of fluid. In order to overcome this disadvantage, we have designed an apparatus which varies the times of suction over a selected period. It fills the troublesome role previously filled by nursing staff in confirming the satisfactory function of gastric tubes. Thus not only does the tube not become blocked but gastric transit is restored more rapidly which not only leads to savings in the cost of intensive care but offers additional technical security.

[A new vascular shunt catheter (author's transl)].

For over 10 years, many authors have attempted to obtain vascular exclusion by intubation with rigid catheters: rubber tube, Argyle is catheter, special catheters with 1, 2 or several full balloons. Owing to this regidity, introduction is difficult and this calibre of the catheter is limited, with reduction of the flow. The authors have developed a supple multitoric catheter which takes on its final form only at the desired site, at the time of inflation.

[Intra-abdominal haemorrhage: control by perfusion-dialysis (author's transl)].

Puncture-dialysis has taken its place amongst emergency surgical procedures in the diagnosis of intra-abdominal haemorrhage. On the basis of experimental, theoretical and clinical considerations, it is suggested that the lavage fluid not only be left in the abdomen after diagnostic puncture-lavage, but that lavage should be continued in the form of a perfusion system, in addition to intravenous fluids in order to re-establish or maintain normal pressure levels.

[The use of a new type of haemostatic forceps in trauma of the liver (author's transl)].

Clamping of the hepatic pedicle is an emergency act, limited in time and ineffective in cases of vena cava-hepatic vein reflux. The single forceps suggested are particularly well suited to the morphology of the right lobe, affected in 70% of cases of liver trauma, providing equipotential parenchymatous stereocompression. They have the advantage of being selective, complete, and reversible, and may be applied for an indefinite period. They provide rapid biliostasis and haemostasis and provide time for thorough exploration of the abdominal cavity without any risk of total hepatic ischaemia.
