[Place of peridural anesthesia in aorto-iliac surgery. Preliminary comparative study apropos of 32 patients].

UNLABELLED: Two groups of patients were studied: Twelve retroperitoneal iliac, and 20 abdominal aortic surgery with aortic clamping and bypass graft. Anesthesia was: Pure thoracic epidural T10-T11 for all iliac and 3 aortic surgery. Epidural thoracic plus light general anesthesia for 12 aortic surgery. Classic balanced anesthesia for 5 patients only. Rate of injection of anesthetic mixture and pressure measurement in epidural space are described. RESULTS: Hemodynamic changes during surgery are less in the epidural group. Post operative respiratory assistance was necessary only in the general anesthesia group, and respiratory care easier in the epidural group. Post operative peristalsis was obvious the first post operative day after epidural anesthesia, the fourth day after general anesthesia.

[Vasa-vasorum (author's transl)].

More than a common descriptive interest, this researches about vasa-vasorum have been carried on to give some anatomical basis, to the part acted by those vessels in arterial wall life. Microdissections, X-rays diaphanisation enable us to systematize even in human kind than in animal species, the main aspects of this vascularisation. The conception of a double irrigation, from the lumen and from the vasa of the blood vessels, and the presence of a venous and lymphatic drainage, can give us the basis of an interpretation of the beginning of the main arterial diseases.

[Arterial collateral ways of the limb arteries (author's transl)].

Arterial collateral ways are reviewed correlatively with five differents levels of obliteration : aortic, iliac, ilio-femoral, femoro-popliteal, dista. A double visceral and parietal supply system caracterize each obliterated level; the importance of this double system varies considerably with the site of obliteration.

[The gastro-phrenic ligament].

The present study was carried out in order to investigate if 1) the gastrophrenic ligament was involved in gastric stabilization, 2) the surface of this ligament might be influenced by fundus distension induced by the first deglutition of the newborn. In a series of 23 subjects (15 adults, 8 foetuses) the surface of the gastrophrenic ligament was expressed in % of the postero-inferior surface of the stomach. The gastrophrenic ligament consisted of loose areolar tissue and its surface was rather small (5,89% +/- 3,8 in adults; 4,3% +/- 1,5 in the foetus). These facts led us to conclude that this ligament did not play a very important role in gastric stabilization. Furthermore the difference between adults and foetuses was not statistically significant; so the surface of the ligament could not have been changed at birth.

[Substitute pathways of the arterial system of the lower extremities].

Some ideas emphazied by RENARD and his collaborators were rediscovered.--Anastomosis doesnt always signify compensation and it is often difficult to appreciate the functional importance of the anastomoses shown by arteriographies.--The most valuable compensations are made by short ways. Long ways only come into action when the shorter are obliterated. Finally a certain number of arteries play an important role in the compensatory circulation, that is:--the system of lumbar arteries--the hypogastric artery--the origin of the deep femoral artery.

[Thromboembolic risks and surgery for varicose veins].

The authors carried out a study on 53 patients operated on for varices with the object of determining the risk of postoperative thromboembolism. They tried to answer three questions : 1) What is the magnitude of the risk of thromboembolism after this kind of surgery? 2) What is the value of the different methods of detection available? 3) What attitude should be adopted towards therapy, not of thromboembolism as a complication, but of the threat of thromboembolism?

[Importance of symptomatic balance in peripheral arterial surgery].

A clinical and radiological study searching for a dental or oral infection was performed on thirty six patients before arterial reconstruction by prosthesis. Potential oral or dental infection was found in 16 cases and dental extraction was performed. Previous studies confirmed the interest of oral or dental examination before any vascular prosthesis, which could be a reasonable attitude.

[Vascular thrombosis and oral contraceptives].

In reference to four particular cases where a venous thrombosis associated with the use of oral contraceptives, the authors review the various factors of this problem. The importance of the concomitant use of tobacco as well as risk factors such as hyperlipidemia and hypertension, are especially stressed. These four cases, almost of an experimental nature, permit to correlate precisely the interaction between estro-progestative medications and the occurrence of venous thromboses.
