[Spontaneous rupture of the esophagus (Boerhaave syndrome) in a patient with scleroderma treated by continuous ambulatory peritoneal dialysis].

Esophageal involvement is a common situation found in 50 to 80% of patients with scleroderma, but Boerhaave's syndrome is rare in this context. The authors report the first case of spontaneous esophageal rupture occurring in a chronic renal failure patient treated by continuous ambulatory peritoneal dialysis. In this observation, sclerodermal esophageal dyskinesia, chronic renal failure which is a classical cause of vomiting and the peritoneal dialysis which play an increasing role in the intraabdominal pressure are potential contributing factors to Boerhave's syndrome. In such patients presenting risk factors, even if they are asymptomatic, it seems reasonable to propose esophageal explorations with manometry or/and endoscopy looking for dyskinesia or other complications of gastro-esophageal reflux.

The bronchial arteries: anatomic study and application to lung transplantation.

The bronchial arterial system (BAS) and its territory was studied in dissections of 40 fresh adult cadavers. The arterial distribution was assessed by catheterisation of the ostia and injection of contrast medium. The number of bronchial aa. varied from 2 to 4. The origin of the arteries was between the upper border of T5 and the lower border of T6 in 90% of cases. The intercostobronchial trunk was the virtually exclusively component of the right bronchial arterial system, present in 97.5% of cases. It was associated with an accessory right bronchial a. in 7.5% of cases, which was merely supplementary. A common arterial trunk for both bronchial systems was present in 50% of cases. The left BAS was characterised by the presence of a direct left bronchial a. (LBA) in 76% of cases, and by the combination of two LBAs in 20%, one of which was usually dominant. However, major anatomic networks between the different vessels found allowed reimplantation of the LBA alone in the former situation, and in the latter it was possible to rely on the dominant LBA alone when reimplantation of the different ostia was impossible. The proximity of the different ostia and the interostial interval, which was less than 1.5 cm on average, permitted multiple revascularisations by the same vascular supply.

Anatomic basis of vascular distribution in combined removal of liver and pancreas (28.5.93).

Based on the study of the arterial distribution of 120 hepatic grafts removed from brain-dead patients, the authors assess the possibilities of vascular partition in cases of combined removal of the liver and pancreas. The discussion deals with the vascular distribution of each organ. The presence of a right hepatic artery arising from the superior mesenteric a. (SMA) requires preservation of the SMA with the hepatic graft, while the pancreas is removed with the celiac trunk (CT) and its branches. The presence of a left hepatic artery arising from the CT requires its preservation with the hepatic graft, the pancreas being removed with the SMA and the splenic artery.

[Estimation of liver volume as a function of the individual's morphology].

Computed tomography using transversal scanning, may be usefull in the determination of liver volume. The aim of this study is to evaluate this technique in living subjects and to determine a relationship between liver volume and morphological body surface area and other morphological criteria. In a series of 25 patients, liver volume was computed from the body surface area, using a mathematical function. This method allow a quick and accurate determination of the liver volume which could be used in liver transplantation for a better matching between donor liver and recipient.

[Spontaneous rupture of the spleen disclosing pheochromocytoma].

The authors report a case of spontaneous rupture of spleen inaugurating the symptomatology of a pheochromocytoma. After presenting the observation, clinical problems are considered with a deceptive abdominal symptomatology and myocardial ischemia that could be part of an "adrenergic myocarditis"; the mechanism of ruptured spleen is analyzed. The diagnosis approach is discussed through a reliability study of various explorations: computed tomography has a sensitivity ranging from 93 to 97% which approaches 100% when associated with magnetic resonance, methyl-iodo-benzyl-guanidine scanning seems to be provided with similar reliability. During checking up for pheochromocytoma spreading, ectopic location was not found, but a cold thyroid nodule was detected which allowed suspecting a SIPPLE syndrome. The three-stage surgical approach was required by symptomatology, hemostasis splenectomy, lateral pheochromocytoma excision after a short preparation by blocking alpha and beta, and then total thyroidectomy after extemporaneous confirmation of the existence of a medullary carcinoma of the thyroid. This pathologic association leading to a SIPPLE syndrome is listed as part of the multiple endocrine neoplasias of type II (MEN II).

Adventitial cysts of the popliteal artery.

Adventitial cysts of the popliteal artery are rare. Their pathogenesis is debated. In one of the two cases reported here, there was a communication between the arterial cyst and the articulation of the knee. This supports the embryonic theory that the articular synovium and adventitial cysts have the same mesenchymal origins. Treatment is surgical, with simple evacuation of the contents of the cyst in uncomplicated cases, excision and reconstruction in the others.

[CY 222, a very low molecular weight heparin, in the curative treatment of deep venous thrombosis. Apropos of 95 cases. Clinical and phlebographic results].

Efficacy of a very low molecular weight heparin, CY 222, in the treatment of deep venous thrombosis of lower limbs was evaluated in a prospective clinical trial instituted in November 1984. CY 222 was administered as subcutaneous injections of 0.03 ml.kg-1 daily (750 anti-Xa U.kg-1.d-1) as 3 divided doses over a minimum of 10 days. Efficacy was rated as a function of clinical and phlebographic criteria. The group of 95 patients treated was a heterogenious one: 38% medical, 62% surgical, and 48% of the total group had partial interruption of vena cava previous to study. The period between first clinical manifestations of the deep thrombosis and therapy varied between one day and 3 months (mean: 1 1/2 days). Clinical symptomatology significantly and globally regressed in 88% of the patients. Comparisons between phlebographic findings at start and end of treatment are expressed using Arnesen's score (cf. table).

[Duodenopancreatic injuries. Diagnostic and therapeutic considerations apropos of 25 cases].

A review of a homogeneous series of 25 cases of duodenopancreatic injuries emphasizes the serious nature of the lesions operated upon at the acute pancreatitis stage. An early diagnosis of these duodenopancreatic lesions is essential since they are often included in the context of multiple injuries. Principal diagnostic difficulties arise in lesions due to contusion without associated intra-abdominal injuries. In these cases ultrasound and CT scan imaging provide valuable data, particularly the latter exploration which is 89% reliable in demonstrating pancreatic morphology. Treatment differs as a function of presence of isolated or combined duodenal and pancreatic lesions and of lesional type. It should be as conservative as possible, although exeresis for lesions of body and tail of pancreas is currently performed more frequently.

Morphologic and functional anatomy of the subclavian veins.

50 jugulo-subclavian venous junctions were removed to study the endovenous structures of the subclavian vein and of this junction. The diameter of the subclavian vein is always less than that of the internal jugular vein. Valvules were constantly found, whereas endovenous structures such as those found in the ilio-caval junctions were very rare. In view of these findings, these structures may be regarded as of embryologic origin.

[Giant diverticulum of the sigmoid colon. A rare complication of colonic diverticulosis. Review of the literature apropos of a case].

The authors report a case of giant diverticulum of the sigmoid colon, a very rare complication of diverticulosis of the colon, since only 38 cases have been reported in the literature. The diverticulum was seen at barium enema in a 66-year-old man complaining of digestive symptoms consisting of lower abdominal pain, tenesmus, diarrhea and fever. Segmental resection of the sigmoid colon including the site of implantation of the diverticulum with end-to-end anastomosis at the same operative stage led to definitive cure. On the basis of a study of the literature, the authors define the clinical, diagnostic and pathogenic characteristics of the condition.

[Problems posed by the orientation of the head].

After a brief history of the origin of the planes of section of the head, the authors state that there are two kinds of planes: "convenient" planes and those with a scientific basis. Among the latter, they study those which are based on the sensory organs and in particular, on sight (Broca's alveolocondylian plane) and balance (plane of the lateral semi-circular canal or its branches). The positioning of the head cannot be the result of a single sensory organ and even less of one part of a sensory organ. This positioning results from informations given by nearly all sensory organs.
