Routine investigation by ultrasonography with pulsed Doppler was carried out in 125 patients, candidates for sclerosing injections of the short saphenous. Study of the contents of the popliteal fossa, of the short saphenous, of the position of its junction in relation to the joint line of the knee, as well as detection of a possible satellite arteriole of the short saphenous was undertaken from a hemodynamic and topographic standpoint. A small calibre satellite arteriole of the short saphenous was a virtually constant finding, situated deep to the junction of the short saphenous, parallel to the latter at its origin, and interposed between the popliteal and short saphenous veins. Variations in the size and/or position of this vessel in relation to the saphenous could be considered as being partially responsible for complications of sclerosing injections in this area. Study involved the junction of the short saphenous, its size, continence and position in relation to the joint line of the knee, as well as the presence, size and position in relation to the saphenous of a satellite arteriole.

The hyperemic response induced by the tri-iodinated contrast agent injection for coronarography assesses functional value of the arteriolar areas of coronary distribution. The intracoronary injection of two kinds of micropheres labeled with gamma emitter radionuclides of different levels of energy (99m-Technetium and 113m-Indium) provides comparison of the studied areas-scintigraphies at rest and during hyperemia.

Trying a standardization of methods for studying the microcirculation of the human ovary in reproductive period the authors studied 8 post-mortem ovaries of women aged between 18 and 35 years. It is concluded that the cleared method allows a better observation of the hilar and medullary vessels, while microangiography is better for the cortical vessels. The histological correlation is fundamental for the correct interpretation of the microangiographic images.
