Prevalence rate for inherited thrombophilia in patients with chronic and recurrent venous leg ulceration.

The aim of the study was to determine the prevalence rate for inherited thrombophilia (IT) in patients with chronic (CVU) and recurrent venous leg ulceration. We also investigated and evaluated the severity of the clinical pattern of CVU in patients with and without IT. We examined 110 patients with CVU (the study group) and 110 healthy subjects (the control group).

Portal venous system after endoscopic sclerotherapy of esophageal varices in patients with liver cirrhosis--prospective study with Doppler sonography.

Background/aims: The aim of this prospective, clinical study was an ultrasonographic color Doppler evaluation of morphological and hemodynamic changes in the portal system prior to and after repeated, endoscopic injection sclerotherapy in patients with liver cirrhosis and hemorrhage from esophageal varices.

Methodology: Twenty-six patients before and after complete eradication of esophageal varices by repeated sclerotherapy with 5% ethanolamine oleate as obliterating agent were examined. The diameter of the portal and splenic veins, the patency of the veins, the direction of the blood flow, the mean and maximal velocity of blood flow, spleen size and presence and number of collateral circulation pathways were determined.

[The value of phlebography, USG-doppler and intraoperative tests in diagnosis of perforating venous insufficiency in the calf].

Accuracy of phlebography, color duplex sonography and intraoperative findings have been compared in a group of 29 patients operated for postphlebitic syndrome. The highest number of perforating veins was identified during the operation, fewer on phlebography and the fewest on color duplex sonography. However in the upper part of the calf both the latter were found to be inaccurate.
