High-resolution real-time ultrasonography. Diagnosis and follow-up of jugular and subclavian vein thrombosis.

Thrombosis of the internal jugular and subclavian veins was demonstrated by high-resolution real-time ultrasonography in eight patients. The sonographic findings were an intraluminal mass of low or mild amplitude echoes, loss of respiratory rhythmicity and venous pulsation, absence of vein response to respiratory maneuvers (Valsalva and sniff test) and incompressibility of the thrombotic jugular vein. Follow-up examinations after anticoagulant and local streptokinase therapy allowed monitoring of the treatment. High-resolution ultrasonography is a useful noninvasive technique for the diagnosis and follow-up of therapy in thrombosis of the jugular and subclavian veins.

Intraoperative ultrasonography in cystic brain lesions.

Four neurosurgical patients were operated on under real-time ultrasonographic guidance. Two had cystic tumors which were drained through the unincised dura. In one patient a brain abscess was located intraoperatively by ultrasound after a small craniotomy. In a fourth patient with multiple abscesses, one abscess was drained under ultrasonographic guidance through a previous craniotomy. Using intraoperative ultrasonography the length of the operation can be shortened and normal brain tissue spared. Intraoperative ultrasonography is of special value in cystic lesions which can be drained under ultrasonographic guidance.

Thickness of the gallbladder wall in patients with hypoalbuminemia: a sonographic study of patients on peritoneal dialysis.

Thickening of the gallbladder wall in patients with ascites has been attributed not to the presence of ascites but to the associated hypoalbuminemia. The contribution of hypoalbuminemia was examined by sonographically measuring the thickness of the gallbladder wall in 12 patients with chronic renal failure who were on peritoneal dialysis. All patients had hypoalbuminemia, with serum albumin levels of 2.2-3.3 g/dl (normal range, 3.5-5.0 g/dl). In all patients, the thickness of the gallbladder wall was within the normal range of less than 3 mm. In the patients studied, hypoalbuminemia was not a cause of thickening of the gallbladder wall even when peritoneal fluid was present.

Ultrasonography in the radiologic evaluation of children with urinary tract infection.

A prospective blind study comparing the findings of ultrasonography, intravenous pyelography, and voiding cystourethrography was conducted on 81 patients to examine the place of ultrasonography in the initial radiologic evaluation of children with urinary tract infection. The patients' mean age was 4.8 years; 15 were male. Forty-eight were inpatients (mean age, 3.2 years) and 33 were outpatients (mean age 7.2 years). In 29 patients (35.8%) abnormality of the urinary system was detected by one or more of the three imaging procedures; 21 were inpatients and eight were outpatients. The most frequent finding was vesicoureteral reflux, occurring in 62.1% of the pathologic cases. The findings at ultrasonography correlated well with those of intravenous pyelography in 73 of the 81 studies (90.1%), but they failed to demonstrate double collecting systems and several of the minor changes. However, ultrasonography in combination with cystourethrography identified all patients who had abnormal urinary systems, except for two children with negligible findings. Moreover, ultrasonography and cystourethrography together identified all 11 patients, nine of them inpatients, in whom surgical treatment was indicated. It is concluded that ultrasonography can successfully replace intravenous pyelography as a screening imaging procedure for the urinary system, but because of the superiority of intravenous pyelography in the detection of some types of lesions, intravenous pyelography will be required whenever ultrasonography or cystourethrography results are abnormal.(ABSTRACT TRUNCATED AT 250 WORDS)

Tetra-amelia with multiple malformations in six male fetuses of one kindred.

An Arab Moslem kindred is reported in which six abnormal male fetuses were born in three closely related sibships. They had amelia, malformed head and other severe skeletal and visceral malformations. The similarities and differences between the developmental and inherent characteristics found in our patients and in families with Roberts syndrome are discussed.

Ultrasonography in Crohn's disease.

Eighteen patients with acute and subacute Crohn's disease were examined by ultrasound. In 7, ultrasound was the initial screening procedure leading to the diagnosis of Crohn's disease. This diagnosis was subsequently proved by results of barium studies. The most frequent ultrasonographic finding was conglomeration: an irregular mass containing scattered echodense and sonolucent areas that represented matted inflamed bowel loops. Some of the conglomerations showed a fine diffuse echo pattern with ill-defined posterior borders due to poor transmission. These areas denoted mesenteric fat covering the matted loops (fatty conglomeration). Other ultrasonographic findings were the "target" or "bull's eye" sign, abscess formation, and fluid in the cul-de-sac.

Idiopathic cricopharyngeal achalasia.

Two neonates with cricopharyngeal achalasia are presented. In one of them myotomy of the cricopharyngeus relieved the obstruction. In the other baby, the symptoms disappeared without surgical treatment.

Diagnostic radiology in wartime.

During the Lebanon War, 1982, over 80% of the wounded were sent from the triage area of the hospital directly to the radiology department. This article reports changes in the working pattern and organization of the department that were instituted for emergency treatment in wartime, and describes radiological examination methods for different organs. Computerized tomography is emerging as the most important diagnostic tool in addition to conventional radiological examinations.

Sonography for diagnosis and follow-up of neonatal adrenal hemorrhage.

Neonatal adrenal hemorrhage was diagnosed by ultrasound as an echo-free mass superior to downward displaced normal kidneys in three newborns. In one, the adrenal hemorrhage was bilateral. Fine needle aspiration was performed to confirm the diagnosis in one case. The babies were followed-up until adrenal calcifications were seen on ultrasound as linear echoes with posterior acoustic shadowing. These calcifications were confirmed by plain films. It is suggested that the diagnosis of neonatal adrenal hemorrhage should be based on ultrasound and on one initial intravenous urogram. Follow-up examinations should be restricted to ultrasound and plain films. In doubtful cases fine needle aspiration can be added for confirmation.

Causes of abnormal right diaphragmatic position diagnosed by ultrasound.

Fifty patients with an abnormal right diaphragmatic position on posterior-anterior and lateral chest films and five patients following right thoracotomy were examined by ultrasound. The transabdominal and intercostal approach with the liver as an acoustic window was used. In all patients the cause for the change in the diaphragmatic position and the nature of an opacified right hemithorax after thoracotomy and pulmonectomy were identified.

Ultrasonography in developmental displacement of the hip: a critical analysis of our results.

In a prospective study to evaluate developmental displacement of the hip, we have used real-time sector scanner ultrasonography. One thousand eight ultrasonographic examinations performed on 444 hips were evaluated. The study was performed by an independent assistant who compared his interpretations to the interpretations of the principal authors. The results show that real-time sector scanning has not been proven to be an absolute imaging method. We believe that these disadvantages might be eliminated by proper use of real-time linear scanners.

False uroradiologic pathology in children with urinary tract infection and fecal impaction.

Intravenous pyelography (IVP) in 5 children with urinary tract infection detected various uroradiologic abnormalities. Despite the lack of history of constipation, a common denominator to all 5 patients was the finding of fecal impaction in the rectosigmoid. In the first 3 patients, repeated complete IVP series done several weeks later and after preparatory bowel enema were normal. In the last 2 patients, the radiologic investigation was interrupted when the first exposure disclosed uroradiologic abnormalities and fecal impaction. Following immediate bowel enema, the studies were completed on the same settings to be found normal. It is concluded that in the face of fecal impaction, pathologic uroradiologic findings should be interpreted with great caution. Moreover, in such cases, intraprocedure cleansing enema is feasible and recommended.
