New concepts in preoperative imaging of anorectal malformation. New concepts in imaging of ARM.

In this study of 14 patients with anorectal anomalies CT and MRI were employed for preoperative assessment. The use of a pressure enhanced water soluble enema via the colostomy proved to be an extremely efficient method for showing a fistula. MRI studies were enhanced by the use of vaseline oil and in one case this technique was used prior to surgery to provide important information by injecting through a perineal fistula. CT and axial MRI proved to be more valuable than sagittal MRI which is only useful for the length of the atretic segment. The authors consider that a combined approach using pressure enhanced water soluble enema and MRI will provide the most valuable preoperative information to plan a successful operative approach and enable an accurate prognostic evaluation of continence in these difficult and complex patients.

Concepts of combined endovascular and surgical treatment for dural arteriovenous fistulae: concepts derived from experience in treating three unusual lesions.

BACKGROUND: We describe a treatment protocol for patients who have a dural arteriovenous fistulae (dAVF) not curable solely by an endovascular approach. MATERIAL AND METHODS: Three patients suffering from neurological impairment due to a complex dAVM (intracranial haemorrhage 2, intracranial hypertension 1) were treated by a combination of arterial embolization treatment and subsequent surgery. RESULTS: Marked reduction of flow was achieved by embolization of the main arterial feeders of the fistulae. Surgery eliminated the residual dAVFs completely and without permanent morbidity. CONCLUSION: It is necessary to eliminate a dural fistula completely, especially in a patient whose fistula had drainage or reflux into cortical veins, which have a high risk of intracranial haemorrhage and venous hypertension. We present an approach to treatment using transarterial embolization and early surgery which may offer a safe and effective way to achieve complete elimination of the lesion, avoiding increased risk to important venous drainage.

Serum progesterone predicts abnormal gestations in clomiphene citrate conception cycles as well as in spontaneous conception cycles.

OBJECTIVE: To determine if a "discriminatory" P concentration could be established that predicted abnormal early pregnancies in clomiphene citrate (CC)-conceived cycles. DESIGN: Progesterone concentrations of gestations between 28 and 49 days from last menstrual period in both spontaneously conceived and CC-stimulated cycles were analyzed using a relative-operating characteristic (ROC) curve. INTERVENTIONS: Serum P concentrations were measured in 222 pregnant patients from the first 49 days of gestation. One hundred sixteen patients conceived in a spontaneous cycle and 106 patients conceived in CC-treated cycles. Two by two contingency tables were used to calculate the true-positive (sensitivity) and false-positive rates at 20 specific P at 20 specific P concentrations. A ROC curve was then generated by plotting the sensitivity of the test against the percent of normal patients incorrectly classified (false positive) at each P level. The best discriminatory value was estimated in each curve at a point of high sensitivity associated with a minimal false-positive value. The areas under the curve and SE were calculated for each group and compared by the critical ratio z-test. RESULTS: The best discriminatory P concentration was 10 ng/mL (32 nmol/L) for spontaneously conceived pregnancies and 30 ng/mL (95 nmol/L) for CC-treated pregnancies. The area under each ROC curve was significantly predictive. Comparison of the two curves indicated that the ability of P measurements to predict gestational complications was independent of follicular stimulation. CONCLUSIONS: Follicular stimulation with CC increases the discriminatory P value that predicts gestational normalcy but does not alter the clinical utility of the test.
