Veinous insufficiency

PURPOSE OF THE STUDY: Arthroscopic lateral retinacular release is one of the most employed procedures for patellar chondromalacia. A literature review show a complication rate of 10 to 18 p. 100 of postoperative hemarthrosis. This work aims to study the vessels anatomy of the lateral side of the knee in order to find anatomical landmarks allowing to avoid or coagulate them. MATERIAL AND METHODS: Thirty-three cadaver knees were dissected. Measures were made related to the lateral superior genicular artery and the lateral inferior genicular artery...

We report one case of hepatic encephalopathy following the administration of a somatostatin analogue (lanreotide) in a patient with a pancreatic endocrine tumor and liver metastases. Hepatic insufficiency was absent. The diagnosis of hepatic encephalopathy relied upon a positive re-challenge test, elevated veinous ammonemia, suggestive findings on electroencephalogram and lack of recurrence after lanreotide discontinuation. Encephalopathy was thought to be due to a significant decrease in hepatic blood flow caused by lanreotide; an associated thrombosis of the portal vein may have played a facilitating role...

The writers reminded that a consensus on Classification of veinous diseases, necessary to build up homogeneous samples, was being set up. Now, they are introducing a thermal nosology that is as useful. Next, the history of spas, the characteristics of Thermal Springs and thermal practices as well as their results are described. The writers present a standardization of the observation and control parameters of the therapeutic effects. The rigorous and scientific process was defined by an interdisciplinary scientific process was defined by an interdisciplinary scientific Council and it is based on the creation of a Computerized Laboratory of Research and a Thermal University...

Of the importance of chronic veinous insufficiency in the etiology of the ischaemic troubles of the legs and also, for the same reasons, of the feet and toes, troubles often wrongly considered as exclusively of arterial origin. Of the interest of suppressing the points of veinous reflux, even when no varicose condition is detected, notably on the arteritic selected upon functional vascular explorations and T C Po2 (transcutaneous Oxygen pressure). In the present case, a frequent, not to say almost constant, indication of sclerotherapy and crossectomy (arch of the aorta)...

The systematic examination of 237 children, aged between 2 and 17 years, and whose mothers suffer from varicosis, has revealed the absence of varicosis in 10 of these children. Some of them belonged to the same more or less affected family. The 227 others, that is 96%, had 1 to 4 saphenae which were pathological, palpable, with hyperplastic wall, more or less turgescent outside all effort. All the 4 saphenae of 129 children, that is 54%, were hyperplastic. 35 had only three (15%), 53 had only two (22%) and 9 had only one pathological saphena (4%)...

On the basis of more than 10,000 phlebographies we believe that the ascending phlebography with control by means of x-rays and accurate photographs, the so-called "phleboscopy", is the most appropriate of all techniques of phlebography for a routine ambulant examination of the veins. By means of phlebography we succeed in employing our therapeutical measures accurately, control of therapeutic results is possible. The phlebography informs about the morphological condition of the veinous system and the defluxion conditions...

Hepatic echo-angiostructure: echo-anatomical study of the intraparenchymatous canal With a suitable technique (real time, grey scale) hepatic ultrasonography is able to display intraglandular ductal elements: portal veinous network, supra-hepatic veinous network, and, if enlarged intrahepatic biliary tree. A careful echoanatomic study is necessary to identify the enlarged biliary network in case of obstructive jaundice; such a study is also necessary not to confuse normal ductal structures, insufficiently displayed, with pathological reflections - a rather frequent hazard with conventionnal techniques...

Following a nosological discussion of the varicose vein, its histological, biochemical and immunological elements are detailed. The hydraulic conditions are described, and attention is drawn to the microvasculartissue consequences of the stasis, the degree of constraint exercised by the interstitial tissue, and the role played by the intricate "micro fiber" network of the microcirculation: only a part of the capillaries reconnect with the veinlet of the same circulatory unit, the others having to flow toward the veinlet of other units and only one initial lymphatic vein contributing to the evacuation of 3 to 4 veinlets...
