High-output right ventricular failure secondary to hepatic arteriovenous microfistulae. Selective arterial embolization treatment.

A patient with diffuse hepatic arteriovenous microfistulae suffered from secondary high-output right ventricular failure, pulmonary hypertension, and ascites, all of which could be managed by selective embolization of the hepatic artery. The vascular lesion of the liver seems to be essential, although hemorrhagic hereditary telangiectasia , perhaps aggravated by administration of oral contraceptives, may be considered contributory factors in this case.

Sonographic monitoring of biliary endoprostheses.

Biliary drainage by endoprosthesis, inserted either transcutaneously or endoscopically, is as effective and better supported than percutaneous drainage, but harder to control. Forty-four patients with biliary or pancreatic carcinoma treated by endoprostheses were followed up by ultrasound. Sonography was effective in the demonstration of the drainage effectiveness and the detection of prosthetic dysfunction or eventual complications. Consequently, it may be considered a valuable method to complement the biochemical tests in the monitoring of endoprostheses.

Investigation of the venous system in impotence of vascular origin.

Vascular pathology is responsible for about 25% of cases of male impotence. Pudendal arteriography has been the object of numerous publications. Venous conditions explain the majority of erectile dysfunctions in patients with normal arterial anatomy. We have performed cavernography in 30 patients, with monitoring of intracavernous pressure and flow measurement. Cavernograms allowed study of the corpora cavernosa and the venous drainage. Cavernography not only helps in understanding the mechanism of erection but also is essential to the successful treatment of pathologic venous drainage.

A longitudinal study of fetal limb growth.

This article is based on the same population that was previously reported. In this paper, we report the results concerning the fetal limb bones. Growth charts and velocity charts were produced for the humerus, ulna, femur, and tibia. The results are compared with those of the cross-sectional literature.

Cavernometry-cavernography: its role in organic impotence.

The intracavernous pressure necessary to produce a passive erection was recorded in 35 patients suffering from impotence. Among these patients, 5 presented psychogenic impotence. The intracavernous pressure was also recorded at rest during inflow and in the state of erection. The 5 psychogenically impotent patients had passive erections with a flow of 80-120 ml/min. 18 patients suffering from organic impotence developed passive erections at a flow of 80-120 ml/min, while the remaining 12 men needed a flow between 160 and 300 ml/min with visualization of a venous leak. The intracavernous pressure varied between 90 and 110 mm Hg in the state of erection. Artificial erection, induced in impotent men, allows to classify patients with vascular organic impotence into three categories: those with pure arterial insufficiency; those with pure venous leak, and patients with both.

[Radiologic and hemodynamic studies of sexual impotence of vascular origin].

Vascular pathology is responsible for about 25% of male impotence, the arterial investigation is now classical. In our experience a great number of patients showed a normal arterial condition, requiring further venous exploration. Cavernographies and pressure flow dynamics were used to evaluate 45 patients. The cavernograms allowed visualization of structural abnormalities within the cavernous tissues and their venous drainage. The heparinized and diluted contrast medium is infused at 80 to 120 ml/minute until the appearance of an erection, in normal condition the intracavernous pressure rise at greater than or equal to 80 mmHg as long as the erection last. The venous leak is characterized by the absence of erection, no increase of the intra-cavernous pressure and a rapid opacification of venous plexus under a normal perfusion flow.

[A predictive thermographic test of the effect of lumbar sympathectomy].

The benefit of lumbar sympathectomy in the treatment of arteriopathy of the lower limb has been widely proved. To predict objectively its efficiency we developed a simple pharmacologic test under thermographic control. 1 mg of Reserpine is injected in a femoral artery, a digitalized thermography enables to follow the chronological evolution of temperatures of the lower limbs. Thirty patients were investigated, 27 responded positively. The mean increase in temperature of the injected limb reached 1.62 degrees C beginning 2 h 46 after the injection of Reserpine.
