The vascular lesion of the liver seems to be essential, although hemorrhagic hereditary telangiectasia , perhaps aggravated by administration of oral contraceptives, may be considered contributory factors in this case.

These abscesses were subsequent to abdominal surgery (28 patients), biliary obstruction and/or fistula (six patients), trauma (two patients) or acute pancreatitis (one patient). The procedures were usually monitored by duplex sonography and fluoroscopy (35 out of 40 cases), with an angled subcostal approach to the subphrenic space in over 85% of the cases. Forty-three drainage catheters were inserted using the Seldinger method; 37 (86%) had a size of 12 F or more, 21 were 16 F in size. Only two out of 43 catheters were double-lumen sump drains. The clinical condition improved after insertion of the catheter in all 37 patients. Definitive successful drainage, defined as hospital discharge without complementary surgery, was achieved in 32 patients (87%), without major complications. A temporizing effect was obtained in three additional patients (8%) who underwent curative surgery for the underlying process after complete drainage of the abscess. Two patients died from multiple organ failure before their abscess healed. Considerations for successful drainage of subphrenic abscesses include a good knowledge of the subphrenic space anatomy, the use of large-bore drainage catheters and the recognition and correct management of underlying enteric, biliary or pancreatic fistulas.

Left atrial pressure, pulmonary arterial pressure, effective pulmonary capillary pressure, and extravascular lung water were measured in six dogs before and during progressive increase of effective pulmonary capillary pressure. A thin-section CT scan was obtained at each step. Lung attenuation and subjective assessments of ground-glass opacification were compared with hemodynamic variables and extravascular lung water. Ground-glass opacification was identified when effective pulmonary capillary pressure equaled critical pulmonary capillary pressure. Extravascular lung water increased, and the distribution curve of lung attenuation coefficients shifted to higher attenuation from the second measurement at an effective pulmonary capillary pressure greater than the critical pulmonary capillary pressure. Attenuation was highly correlated (r = 0.98, P < .001) with extravascular lung water; ground-glass opacification was detected before a significant (P = .615, analysis of variance) increase in extravascular lung water. Thin-section CT depicts ground-glass opacification when effective pulmonary capillary pressure equals critical pulmonary capillary pressure and before a detectable increase in extravascular lung water. Attenuation reflects extravascular lung water.

It appears as a thin membrane separating the amniotic cavity, which contains the fetus, from the extra-embryonic coelom and the secondary yolk sac. In a prospective study of 32 women in the first 12 weeks of pregnancy, the amnion was demonstrated ultrasonographically in 27 (84 per cent). The embryonic origin of the amnion and possible difficulties in its demonstration by ultrasound are described.
