Study on the left colonic arteries in 15 human fetuses (195 to 360 mm VC). The arterial system was injected 9 times with a mixture of gelatin and Indian ink, 6 times with red coloured stratyl. The left hemicolectomic resections are treated with the Spalteholtz method. The arterial axes are constant: left colic artery, the middle colic artery, the middle branch of the left colic artery, the sigmoïd arteries. A paracolic arch, often branched, was always found, an intermesenteric arcade was sometimes present (20%). Straight arteries became more numerous with function and age. Histologic study showed two types of muscular penetration by these arteries.

[Gastro-omental cystic lymphangiomas. General review and report of two cases (author's transl)].

Omental and gastric lymphangioma : a general review of cases and two personal cases. Lesser omentum tumors are rare. They exceptionnally arise from the stomach. Pathologic fractures : there are three types of lymphangioma simplex, cavernous and combined cystic ones. Microscopic examination shows that cysts are lined with endothelium and the wall is infiltrated by lymphocytes. Lymphangioma frequently occur in childhood (stomacal tumors excepted). Symptoms are those observed either in abdominal tumors, or in ascitis or in acute abdominal disease. The diagnosis is not established per-operatively. Surgical treatment consists in resection of the cyst or in simple drainage. Post-operative prognosis is excellent.

[Arterial vascularization of the temporomandibular joint].

Anatomical and radiological study of the arteries of the temporo-mandibular joint in 18 foetuses and 4 adults. Branches arising from the superficial temporal artery, from the anterior tympanic artery as well as from the deep posterior temporal artery are found in all cases. Branches arising from four other arteries did not occur regularly: those coming from the deep auricular artery, from the transverse facial artery, from the middle meningeal artery, or sometimes directly from the maxillary artery.

[Hepatic resections using an Nd YAG laser. Anatomic and biological results of an experimental study].

Experimental hepatic resections were performed with a Nd YAG laser in 32 New-Zealand rabbits. The beam was simply transmitted by a quartz fiber of 4 degrees 2 and 8 degrees in divergence for the full angle, without any focalization. Section was possible at a power output superior to 20 W requiring short cutting time. Complete hemostasis was obtained as long as the diameter of encountered vessels did not exceed 4,5 mm. Immediately after resection the parenchyma was covered by an ischemic layer varying from 2 to 8 mm. Its thickness rapidly increased to high levels whenever the power output exceeded 40 W or when hepatic pedicle was clamped. Healing process was installed at day 30. There was no hemorrhagic, biliary or septic complication. Eleven animals were alive eight months after. Histological examination revealed four layers: a first one of carbonization, a second of condensed cells, a third of edema presenting disruption of sinusoids, and a fourth one composed of progressively normal tissue. Peripherical veins presented thrombosis of their blood content and coagulative necrosis of their wall while bile canaliculi were preserved. Fibrosis appeared in the edematous layer the 10th day and was completely formed at day 30. Electron microscopic examination revealed shadowy cells embedded in the condensed layer and mitochondrial alteration in the edematous layer. The 15th day foci of cell regenerations were registered. High levels of SGOT, SGPT and LDH (fractions IV and V) were observed immediately after resection.(ABSTRACT TRUNCATED AT 250 WORDS)
