Doppler C.W. study of the lower limb venous hemodynamics during pregnancy and prevention of thrombotic complications.

Thirty-two women (14 primiparae and 18 multiparae) were submitted to clinical and ultrasound investigations during the 1st, 2nd and 3rd quarter of pregnancy and after childbirth, for the evaluation of the lower limb venous system. An increase of the venous pressure in the standing position was present in all the women during the last quarter of pregnancy. In 14 cases varices (6 primiparae, 8 multiparae) with incontinence of the saphenous-femoral valve in 10 (3 primiparae, 7 multiparae), were detected during pregnancy. In these patients a compressive bandage associated, in selected cases, to calcium-heparin therapy (25000 IU/daily) was employed. After childbirth the venous pressure resumed physiological values in 20 of the 32 women while the varices remained in 12 cases. No thrombotic complication of the superficial and/or deep venous system neither hemorrhagic episodes related to calcium-heparin therapy occurred.

[Pyogenic hepatic abscess].

Ten patients, 6 men and 4 women, with a mean age of 53 years, having pyogenic liver abscess, were studied to review the principal features of the clinical and bacteriological diagnosis. In 9 cases the abscess was located in the right hepatic lobe. Bacteriological diagnosis was made in 6 cases: the etiology was nonmicrobian in 3 and two microorganisms were found in the other 3 cases. The isolated pathogens were: Escherichia coli (3 cases), Staphylococcus sp (3 cases), Enterobacter agglomerans (1 case), Citrobacter sp (1 case), Streptococcus sp (1 case). The basic clinical pattern included fever in 9 patients, pain in upper right side of the abdomen in 8, jaundice in 5 and respiratory symptoms in 5. In 2 cases the diagnosis was confirmed by ultrasonography, in 2 by scintigraphy and in 3 both methods were used. Surgical drainage was practiced in 7 patients, with favorable course in 6. Three patients were not operated; 2 died and the third was cured with medical treatment. The importance of the clinical suspicion even with few data is pointed out, specially prolonged fever with painful syndrome in upper right side of the abdomen. The aid of the diagnosis imaging is valuable for verification. The precise bacteriological diagnosis by culture of the material obtained in surgery or by percutaneous drainage of the abscess allows the selection of the most suitable antibiotic therapy.
