Interstitial pregnancy is a rare form of ectopic pregnancy. It is characterized by its implantation in the intra-myometrial part of the fallopian tube. It constitutes a gynecological emergency since its rupture can lead to morbidity and mortality. Its diagnosis remains difficult, and is based on four ultrasound criteria which are not always found. In the absence of rupture, conservative medical treatment is used more and more because it allows anatomical integrity to be preserved. We report a case of interstitial pregnancy successfully treated with a single injection of Methotrexate intramuscularly.

Postpartum hemorrhage is a main cause of maternal death, it can be primary or secondary depending on the time of onset. Although less frequent, secondary haemorrhages keep a high morbidity and mortality rate, which is accentuated by the difficulty of diagnosis and determination of the etiologies especially in rare causes like the pseudo-aneurism of the uterine artery, a vascular abnormality in most cases caused by a traumatic lesion of the blood vessel most often during cesarean section. The diagnosis is examined in front of clinical and ultrasound elements, and confirmed by CT scan, MRI, or angiography which also allows therapeutic treatment thanks to embolization. We report the case of a 27-year-old patient who presented with late postpartum hemorrhage secondary to a pseudoaneurysm of the uterine artery, suspected by ultrasound and confirmed by CT scan, the patient underwent embolization with good evolution. Despite its rarity, pseudoaneurysm of the uterine artery is a potentially fatal complication and must be taken into account in the differential diagnosis of secondary postpartum hemorrhage allowing adequate and rapid management.
