Flow of dialysis fistulas. Noninvasive study performed with standard Doppler equipment.

Ultrasound was used for the measurement of the flow of 50 dialysis fistulas. Mean flow was 806.2 ml/min. There was no difference between the flow of the different types of fistula. It has been observed that although the vein diameter determines the fistula flow, and the former continues to increase even after the fistula has matured, blood flow through the fistula does not increase as its velocity decreases with greater diameters. Flow measurements with ultrasound have important advantages and indications, which are commented.

Ultrasonic blood flow measurements in arteriovenous fistulas: an experimental study.

Femoral arteriovenous fistulas (AVF) were constructed in dogs. Fistulas blood flow was measured simultaneously with standard Doppler equipment, with electromagnetic flow probes and by direct timed blood collection. A good correlation was observed between Doppler and direct timed blood collection (r = 0.822, p less than 0.001) and also between Doppler and electromagnetic determinations (r = 0.747, p less than 0.001). These results lead us to suggest that transcutaneous measurement of AVF flow is possible with standard Doppler equipment and we recommend this technique for the management of AVF constructed in uremic patients.

Multiseptate gallbladder.

Nine cases of multiseptate gallbladder have been reported in the English literature. Another case is presented. We consider cholecystectomy the treatment of choice because it relieves the symptoms and avoids chronic infection and stone formation.
