[Focal nodular hyperplasia and spontaneous intrahepatic porto-portal communication]. / Hyperplasie nodulaire focale et communication porto-porte intrahépatique spontanée.

One case of typical focal nodular hyperplasia of the liver on CT but not proven at pathology was associated with a variation of the intrahepatic portal venous system. The absence of the horizontal segment of the left portal vein with portal supply between the anterior segmental branch of the right portal vein and the umbilical portion of the left portal vein was observed. This finding observed is significant for planning liver surgical procedure such hepatic lobectomy as the incision would interrupt the portal supply.

[Ultrasonic diagnosis in postero-basal pulmonary sequestration in children. Apropos of 8 children including 4 with sequestration]. / L'échotomographie dans les séquestrations pulmonaires postéro-basales de l'enfant. A propos de 8 enfants dont 4 séquestrations.

Ultrasound imaging should be carried out in all children with posterior basal lesions of lungs suspected of being sequestration on standard images. Ultrasonography alone is capable of confirming diagnosis of branchopulmonary sequestration. Results are reported in 8 children, 4 of whom had sequestration.

Diagnosis of pulmonary embolism in hospitalised patients: retrospective survey of an institutional standard.

The aim of the present study was to assess the safety and implementation of a diagnostic strategy in hospitalised patients with suspected acute pulmonary embolism (PE). A diagnostic strategy was established and implemented in a general hospital. A retrospective cohort study, including 400 consecutive in-patients, was performed in order to assess the appropriateness of the diagnostic management and the incidence of symptomatic venous thromboembolic events (VTE) during follow-up. PE was confirmed in 116 (29%) patients. The incremental value of adding compression ultrasonography (CUS) to multidetector-row computed tomography (MDCT) for the diagnosis of PE was 8.6%. PE was appropriately excluded in 169 (42%) patients due to a normal lung scan (n = 34), a negative MDCT providing an alternative diagnosis (n = 94), and a negative MDCT and CUS (n = 41). During follow-up, VTE occurred in 3.5% patients. The almost unique cause of inappropriate management was the absence of further work-up after a MDCT-negative result for PE providing no alternative diagnosis (n = 115). Inappropriate management was associated with a nonsignificant increased risk of VTE (7.2%). A frontline diagnostic work-up based on pulmonary multidetector-row computed tomography associated with a compression ultrasonography of the leg veins is effective and more sensitive than pulmonary multidetector-row computed tomography alone in ruling out pulmonary embolism.
