Midline cerebral arterio-venous anomalies: ultrasound diagnosis.

Ultrasound features of three cases of midline cerebral arterio-venous anomalies of neonates presenting with congestive heart failure are presented. Two cases have CT and angiographic correlation. The third case has post-mortem correlation. Ultrasound easily detected the dilated midline vascular channels in all three cases. Angiography was needed to further define the abnormal anatomy. We suggest a role for ultrasound to screen for midline arteriovenous malformations in neonates with congestive heart failure of undetermined etiology.

Impact of sonography on surgery for primary hyperparathyroidism.

The impact of preoperative sonographic localization of enlarged parathyroid glands was evaluated from the standpoint of operative time and complication rates. There was a reduction in the average time from 135 minutes when findings were false-negative to 111 minutes when findings were positive. The rate of complication was not changed by accurate preoperative localization. When the operative goal is to find all parathyroid glands in every patient, the value of preoperative localization of parathyroid tumors by any current method is slight. Should operative policy favor a search for only one enlarged and one normal gland, or should methods improve to the point that even normal parathyroid glands can be located reliably, noninvasive localization should prove to be useful, safe, and cost-effective, even when it is carried out before initial operation.

Renal biopsies under ultrasound guidance: 100 consecutive biopsies in children.

To examine the number of renal biopsies in correlation with the pattern of referrals as well as the major categories of renal diseases for the procedure peculiar to children, the data of 100 consecutive percutaneous renal biopsies using disposable biopsy needles under ultrasound guidance in 99 children were reviewed. To examine the risks and accuracy of the procedure the estimated depth of the kidney by ultrasound, the actual biopsy depth, the success rate and the complications were evaluated. With rare exception, 1 core of renal tissue was obtained per single needle insertion; 109 needle insertions yielded 103 cores. Of the specimens 92 per cent contained more than 10 glomeruli. Gross hematuria with the first voiding post-biopsy occurred in 12 per cent of the cases but persisted beyond 24 hours in only 1 per cent. No long-term complications were observed. Percutaneous renal biopsy with the disposable needle guided by ultrasound represents a considerable advance in diagnostic technique and deserves wider application in the evaluation and management of a number of pediatric kidney disorders.

Traumatic rupture of the diaphragm: real-time sonographic diagnosis.

Traumatic rupture of the diaphragm may be caused by either penetrating or blunt trauma. The diagnosis is often delayed because of attention to other serious injuries or lack of specific clinical and radiographic signs. In cases of penetrating peridiaphragmatic trauma, the possibility of a diaphragmatic laceration may not be considered, or the plain film findings may be extremely subtle or absent [1]. We report a case of delayed presentation of traumatic diaphragmatic hernia demonstrated by real-time sonography [2]. To our knowledge, this is the first reported case in which sonography provided a definitive diagnosis and prompted immediate surgical repair.
