Ascending aorta syphilitic aneurysm presenting as a dystrophic disease.

A 37-year-old female originating from Central Africa presented with cardiac failure, aortic insufficiency and aortic root dilatation of supposed dystrophic origin. Left coronary ostial dilatation and dense adhesions between the aorta and the pulmonary trunk at operation were the only unusual features. However, pathological examination evoked a syphilitic disease and serology confirmed luetic infection. The diagnosis and the therapeutic approach are discussed. Syphilitic aneurysms belong to the protohistory of vascular surgery, but, in the antibiotherapy era, tracking a syphilitic aneurysm is like fishing for coelacanth. When this pathology mimics a dystrophic aneurysm, diagnosis and therapeutic attitude becomes hazardous and justifies the present report.

Rupture of infected superficial femoral artery aneurysm. A case report.

A case of misdiagnosed infected superficial femoral artery aneurysm is presented. It was initially misdiagnosed as thrombophlebitis. Surgical excision and repair with a saphenous vein interposition graft was performed. The diagnosis of this disease is difficult because there is a lack of signs and symptoms. Staphylococcus aureus and enterobacter are the two most common organisms responsible for infected peripheral aneurysms. Surgery is the standard treatment: ligation, drainage and resection with or without arterial reconstruction depending upon the aneurysm localization.

Isolated supradiaphragmatic descending thoracic aorta stenosis in a Takayasu's disease: surgical cure.

A 21-year-old male patient presented with a typical middle aortic syndrome. Echography disclosed a severe narrowing of the lower thoracic aorta with parietal thickening. The isolated character of the lesion was confirmed by magnetic resonance imaging and aortography. The surgical cure was realized by a Dacron bypass between the upper thoracic descending aorta and the juxta-diaphragmatic thoracic aorta. Aortic biopsy confirmed Takayasu's disease. Postoperative course was uneventful with normalized blood pressure. The therapeutic options, surgery versus percutaneous dilatation and stent, are discussed.

[Physiopathology of bedsores].

Pressure is the primary pathogenic factor in the development of decubitus ulcers. Other major factors are shearing forces, friction and moisture. Significant intrinsic risk factors are immobility, age-related diseases, nutritional status, medications and smoking. The morbidity and mortality related to the complications of pressure sores are quite significant. Prevention is essential and is best achieved by identification of high risk patients. The therapeutic approach is based on the grade of pressure ulcer.

Consecutive infected aneurysms caused by salmonella.

Treatment of infected aneurysms consists of operation, which depends on the location and pathologic type, and antibiotic therapy, before and at least six weeks following operation. The authors present a case of two consecutive aneurysms occurring in a patient with Salmonella infection. Full recovery was obtained after surgical excision of the aneurysms, prolonged antibiotic therapy, and cholecystectomy.

[Mercury strain gauge plethysmography. A noninvasive exploration method for monitoring the efficacy of treatment of deep venous thrombosis].

The plethysmographic tracings of a patient presenting a deep venous thrombosis, give information about the functional evolution of the affected limb. The plethysmographic parameters which are used to estimate the efficacy of the treatment of the deep venous thrombosis are: the venous capacitance, the venous outflow and the venous pressure. These values are always compared with the contralateral limb. The decision to stop an anticoagulant treatment is made after observing an increase of the venous capacitance and outflow and, simultaneously, a decrease of the venous pressure. During the last three years, we have followed up 200 patients with this method. It allows a rational therapeutic management which is based on the objective monitoring of the functional potentialities of the venous system.

[Aneurysm ruptures of the abdominal aorta].

Rupture of an abdominal aortic aneurysm remains a dramatic complication and its operative mortality is still about 50%. The authors reviewed 41 cases of ruptured abdominal aortic aneurysms which were operated from 1978 to 1983. On arrival at the hospital and after clinical diagnosis, the patients were rapidly brought to the theatre without specialized complementary examinations. Coated Dacron prostheses were used in all cases. The operated patients were brought to the intensive care unit where special attention was given to central venous pressure, arterial pressure and capillary wedge pressure (Swan-Ganz-catheter). The authors tried to determine the influence of shock, preoperative delay, blood loss, age and associated diseases on the mortality rate. In this series the perioperative mortality (30 days) could be reduced to 39%.

Continuous monitoring by microprocessor from the operating room to the intensive care unit.

The "Chronicler" is made up of a microcomputer (the CPU is a Motorola 6809), an alphanumeric-graphic display with keyboard and a printer. The system is connected to several physiological signal monitors and in our application to a mechanical ventilator under electronic control. It collects every 5 seconds - or at each breathing cycle if required - all the data supplied by the various measuring devices including those in the mechanical ventilator. The time basis for displaying and storing the data is a multiple of the data acquisition time basis; it is selected interactively by the user during operation. Up to five raw analog curves (f.i. capnogram, pulmonary artery pressure curve) can be displayed and their morphology can then be examined. Manual data are entered or retrieved at any time. The system was designed by Dr. Demeester's team in order to help the anesthesiologist during and after anesthesia. Clinical use of the system by our staff has convinced us that indeed it is of great help in the control of general anesthesia: this results from the very clear and efficient presentation of the data both as numbers and curves; an alarm program under interactive control of the user makes surveillance still easier; furthermore the use of the system is simple and convenient. Finally, when surgery is over, a standard report is automatically printed; it is equivalent to a manually written anesthesia report. The data are stored on floppy disks and can be processed later for retrospective analysis in order to investigate, for instance, the influence of surgical maneuvers and of drugs on physiological parameters. The "Chronicler" is thus a tool for dynamic monitoring during anesthesia; it is also a powerful tool for clinical and physiological research.

Aneurysm of the descending thoracic aorta in a young woman.

The diagnosis of a thoracic aortic aneurysm in an otherwise healthy young woman is a very rare occurrence. The Authors report the case of a woman aged twenty-two in whom such an aneurysm was discovered the day after delivery. Physical signs and radiological documents are presented and early surgical treatment is described. The Authors made a survey of the world literature and emphasize the abnormally high incidence of aneurysms in women of child-bearing age. Etiopathological factors are detailed.

[The application of informatics to mercury gauge plethysmography].

In this study, the authors present a computerized mercury-gauge plethysmography device. The electrical signals collected by the plethysmograph are sent to the computer where they are analyzed by a specially devised interpretation program. The graphs are flashed on the screen, the parameters are automatically and instantly calculated, and a printed-out medical report may be obtained at the end of the test. The various characteristics of the material and the program are presented.

[Effect of "anti-thrombosis" stockings on the venous hemodynamics of the lower extremities. Study using mercury gauge plethysmography].

Study by plethysmography with mercury gauge. The authors have analyzed the effects of "anti-thrombosis" stockings on venous hemodynamics of 18 lower extremities, by plethysmography with mercury gauge (Periflow J.S.I.). With this method, they delineate the limits of efficacy of the use of only elastic stockings as prophylactic treatment of the thrombo-embolic disease in immobilized patients.

[Arteriovenous fistulas. Apropos of 5 cases].

An arterio-venous fistula can be defined as being a vascular anomaly in which there are one or more direct or indirect communications between an artery and a vein, without the capillary network being involved, this latter therefore being short-circuited. After the presentation of five cases, the authors review the literature on the subject.
