Intra-arterial DSA and duplex-Doppler ultrasonography in detection of vascularized inguinal lymph node.

Twenty-three patients with ischemic disease of the legs referred for routine preoperative angiography were examined with intra-arterial DSA and high resolution ultrasonography with duplex-Doppler to detect inguinal lymph nodes. None of the patients had evidence of malignant or lymphomatous disease and only 3 had skin ulceration on the foot. DSA detected nodes in 9 patients (39%). In 3 cases the nodes were highly vascularized. Ultrasonography detected lymph nodes in 16 patients (70%). In all but 2 nodes a high velocity arterial flow was recorded. It is concluded that DSA and particularly duplex-Doppler ultrasonography are sensitive methods to detect vascularized lymph nodes and that such nodes are found in many patients with no evidence of malignancy or infection.

Diagnosis of cystic hydatid disease: role of aspiration cytology.

Fine needle aspiration of mass lesions is reported in eleven patients in whom cystic hydatid disease (CHD) was not a differential diagnosis or whose serological results were negative. Aspiration was continued until no more fluid could be obtained. In five patients aspiration was done under ultrasound guidance. No sequelae were observed that could be attributed to aspiration per se. Aspirated fluid was stained with haematoxylin and eosin and giemsa or was passed through 5 micron polycarbonate filters which were then stained in the same way. The aspirated material and polycarbonate filters were also stained with trichrome which proved the best stain to demonstrate the acid-fast hooklets. Such filtration of the total volume of the aspirated material or that evacuated at operation is simple, quick, and accurate.
