[A difficult therapeutic dilemma: pneumoperitoneum in severe blunt injuries treated by respiratory or cardiorespiratory resuscitation].

In the particular context of severe blunt trauma treated with cardiorespiratory resuscitation or, more simply, with positive-pressure ventilation, the occurrence of pneumoperitoneum always raises difficult problems of etiological diagnosis, which in turn lead to a difficult dilemma on the treatment to adopt. In fact, while the air released by the alveolar baro-trauma can, once a given pressure is exceeded, migrate into the retroperitoneum and produce a non-surgical pneumascos (for which the other possible causes are far more exceptional, and rather are unpleasant surprises, such as this orogenital induced PPT in Gantt's female patient, conversely the pressurized air from true ruptures of intraabdominal hollow organs may migrate into the mediastinum and cause a thoracic air leakage syndrome that perfectly simulates this pulmonary baro-trauma. Therefore all the paraclinical means required must be used to confirm--or rule out--this diagnosis of perforation, which demands emergency surgery. However, if there is any doubt, the consensus is that emergency surgery is recommended as it is better to accept blank laparotomy than to oversee a gastrointestinal rupture with all its severe complications of evolution.

Surgery and chemotherapy. A new method of treatment for squamous cell bronchial carcinoma.

Between April, 1981, and December, 1982, 32 patients with squamous cell bronchial carcinoma were treated with a chemotherapy regimen followed by operation. The preoperative chemotherapeutic agents used were cisplatin, bleomycin, and mitomycin C. A thoracotomy was performed 3 to 4 weeks after the last day of the last treatment. Of the 29 undergoing resection, three (10.3%) had no tumor cells in the resected specimen and four (12.5%) had only a few neoplastic microcenters in tissue necrosis or fibrosis. We suggest that the use of this new chemotherapy combination with surgical resection provides excellent palliation, increases resectability, and has a potential for increasing the cure rate in squamous cell carcinoma of the lung.

[Solitary fibrous tumors of the visceral pleura. 5 cases].

Five new cases of solitary fibrous mesothelioma of the visceral pleura support this review of the literature. Well encapsulated and usually pediculated, these tumours remain asymptomatic for a long time and are in most cases an incidental finding on radiographs of the chest. The precise site of the tumour can be identified by artificial pneumothorax. Some large tumours are accompanied by extrathoracic signs, i.e. hypoglycemia and hypertrophic pulmonary osteoarthropathy. Histological examination discloses whorls of collagen fibres with scattered spindle-shaped cells. Electron microscopy reveals characteristic features of both fibroblasts and mesothelial cells. Complete surgical removal is the best treatment of localized fibrous mesotheliomas of the visceral pleura. Post-surgical recurrences are rare, and late recurrences (up to 16 years after excision) are usually benign and of good prognosis.

[Branchiomeric mediastinal chemodectoma: a case report and literature review].

Among non-chromaffin paragangliomas, the so-called aorticopulmonary or branchiomeric mediastinal chemodectomas are very rare tumors. A case is reported, and 57 similar cases described in the literature are reviewed. As recommended by Olson, a separate group was instituted of 21 cases of the so-called posterior mediastinal or aorticosympathetic group of the costovertebral groove. In principle, aorticopulmonary chemodectomas are non-functional, and in 9 out of 10 cases follow a slow and benign course extending over many, or even tens of years. In contrast to carotid and jugular paragangliomas they are rarely multifocal: when this is the case it is difficult to confirm the presence of metastases, this being however the most reliable criterion of their malignancy. The fortuitous discovery on a radiography of a tumor of the anterior and middle compartments of the upper mediastinum should invoke the presence of an aorticopulmonary chemodectoma, and lead to arteriography of the aortic arch region. Diagnosis is made essentially by pathological examination. Treatment is exclusively by surgical excision, and this was complete in nearly half of the cases treated. Prognosis is not hopeless after partial removal, however, and a relatively comfortable survival can be obtained extending over many years.

[The atrio-ventricular junction: descriptive aspects].

An attempt is made to give a new, revised and more adapted description of the atrio-ventricular junction. This description is based on our personal observations and on data collected from the anatomical and embryological literature of the last 30 years. A fibrous layer interrupting muscle continuity exists between the atria and the ventricles. This non conductive fibrous structure - classically referred to as an Atrio-Ventricular Ring - is not a tendinous ring (LOWER) or a cordlike annulus: it is a fragile lamina which also serves as anchorage for the A-V valves. In no way, can it provide a secure site for the placement of sutures in valve surgery. Both on mitral and tricuspid sides, the so-called A-V ring has a crescentic shape rather than an oval or circular shape. It is best divided into two segments for descriptive purposes: an aorto-septal and a scissural segment: The aorto-septal segment (antero-medial) is thicker and tougher. It presents close, important and dangerous relation-ships - with the postero-lateral part of the aortic root, - and with the vital structures located in the complex junctional zone of the 4 heart cavities (carrefour des cavités cardiaques). The scissural segment (postero-lateral) which forms the deepest part of the A-V fissure, is represented, on both sides, by the subvalvular lamina. This horseshoe shaped lamina is thin and fragile. It is easily stretched following the A-V ostium enlargement, resulting in functional mitral or tricuspid insufficiency.

[First cases of surgical pulmonary cryptococcosis in Vietnam].

Two cases of tumoral isolated pulmonary cryptococcosis are reported. The rarity of the facts explains that diagnosis is usually surgical, the inflammatory and necrotic pseudo-tumour swarming with yeast-like micro-organisms, easily recognizable by their thick gelatinous capsules.

[Gastro-duodenal artery arising from the superior mesenteric artery].

These exceptional anomalies of the gastro-duodenal (G.D.) arteries provide a better understanding of certain very odd vessels found on coeliac or superior mesenteric arteries selective arteriography. In our series of 400 dissected bodies, a typical origin of the G.D. artery from the superior mesenteric artery is noted in 4 cases : the aberrant vessel is identified as a G.D. artery because of a) its course, b) and its two usual terminal divisions : superior pancreatico-duodenal and right gastro-epiploic arteries. On the other hand, we have 10 cases of G.D. artery arising from both coeliac hepatic and superior mesenteric arteries with:--a dominant hepatic branch in 6,--a dominant mesenteric branch in 3,--and a balanced origin in 1. A G.D. artery looping around the common bile duct to reach the anterior surface of the pancreas (Michels) was never seen in this series.

[Small veins of the heart auricle].

A rich venous network in the atria of the human heart, has been demonstrated by the "corrosion-fouille" technic with direct injection. The atrial veins may be arranged in 2 main groups:--the group of the Coronary Sinus for the left atrium.--the group of venae cordis parva for the right atrium (1), the interatrial septum and the neighbouring parts of the left atrium. The venae cordis parva may be subdivided into:--those descending to the right atrio-ventricular sulcus and ending in the right atrium or in a "right coronary collecting channel" (2) (small cardiac vein, Adachi common channel, Parsonnet subendocardial vein of the right atrium).--and those opening by the Lannelongue foramina into the right atrium. Are described 4 principal foramina and veins, arranged in 2 groups:--the group of the S.V.C. ostium, corresponding to the Superior Atrio-Septo-Nodal artery, with 3 veins, the Anterior Lateral vein (or vein of the cavo-auricular notch) for the Sino-Atrial node, descending along the sulcus terminalis, the Anterior Superior and Posterior Superior veins for the interatrial septum, the adjacent parts of the right and left atria. The large ramus from the top of the left atrium, a tributary of the Posteror Superior Vein, corresponds to the homonymous collateral of the Superior A.S.N. artery.--the group of the Coronary Sinus ostium, corresponding to the Inferior A.S.N. arteries, with the Anterior Inferior vein, returning blood from the A-V node region. Of these 4 veins, only one originates on the lateral side of the S.V.S. ostium; the 3 remaining lie on the interatrial septum, near the corresponding angles: Anterior-Superior, Posterior-Superior and Anterior-Inferior.

[A familial case of thoracic outlet syndrome. Clinical, radiological study with treatment (author's transl)].

The authors report the clinical and radiological study and the treatment of a fifteen members family (the two parents and their thirteen children) affected with a thoracic outlet syndrome secondary to a cervical rib and or an apophysomegaly of the seventh cervical vertebra. On the fifteen people considered, the father being deceased has not been examined but has an evocative clinical history. The mother has a clinical impairment with a late beginning and no radiological sign. Twelve children have clinical and radiological signs, one has radiological without clinical signs. Three children underwent a surgical treatment, the others only medical treatment. There is no satisfactory correlation between the clinical features and electrical investigations (electromyography, nerve conduction studies) and radiological examinations. The semiology is vascular, neurologic or mixt. Roos test seems more reliable than that of Adson, Calb and Roth, and Saunders. Eight grand-children out of fourty have been examined. Five have clinical and radiological signs, three have casual radiological signs. The radiological impairment of this family contrasts with the normal frequency of cervical anomalies in the population which is 0,12 to 1%. The family impairment of the thoracic outlet syndrome is rarely reported.
