[Atypical abdominal pain in the first trimester of pregnancy]. / Douleurs abdominales atypiques au premier trimestre de la grossesse.

We report the case of a 22-year-old woman who presented a violent epigastric pain at eight-weeks gestation. Superior mesenteric vein thrombosis was detected, with an extension to portal vein and remaining blood flow. Screening for thrombophilia revealed a heterozygote prothrombin gene mutation. Portal vein thrombosis is uncommon and difficult to diagnose. Diagnosis is made by Doppler ultrasound, a second intention test to be done in case of unusual upper abdominal pain during pregnancy.

[Laparoscopic hemi-hysterectomy for pseudo unicornuate uterus: apropos of 3 cases]. / Hémi-hystérectomie coelioscopique pour utérus pseudo unicorne: à propos de 3 cas.

Surgical management of unicornuate uterus with rudimentary horn is justified because of disabling dysmenorrhea but also because of associated morbidity and mortality complications. We describe here three new cases of laparoscopic removal of the horn following a new improved surgical technique.

[Spontaneous rupture of uterine varices in the third trimester of pregnancy]. / Rupture spontanée de varices utérines au troisième trimestre de la grossesse.

We report a case of spontaneous rupture of a uterine varicosis in the third trimester of pregnancy resulting in massive peritoneal hemorrhage and maternal shock. This patient with an uncomplicated pregnancy presented symptoms suggestive of abruptio placenta with foetal distress. A caesarean section was performed identifying the cause and permitting the treatment of this syndrome. Since 1950, only 8 cases have been reported.

Diagnosis of arachnoid cysts on prenatal ultrasound.

The aetiology and physiology of congenital arachnoid cysts are a source of controversy. We report a case where fetal cerebral ultrasonography shows an extraventricular sonolucent cystic formation after 20 weeks of pregnancy. Ultrasonography provides its topographic relations with adjacent brain structures and is also used to diagnose possible associated malformations. MRI confirms the ultrasonographic findings by investigating cerebral gyri. The rest of the examination involves detection of extracerebral anomalies and a karyotype study. Other differential diagnoses will be considered as a function of the embryological origin and topography of arachnoid cysts. The outcome of these arachnoid cysts depends on the age at the time of diagnosis, their size and their topography. The problem is that hydrocephalus, due to compression of the cerebrospinal fluid drainage pathways, may develop. Treatment, if necessary, is nearly always surgical.
