Objectives: To provide recommendations for management of interstitial and ovarian pregnancies. • Normal and ectopic pregnancy implantation can be accurately characterized with 3D ultrasound, particularly interstitial ectopic pregnancy. A cornual ectopic pregnancy is defined as a gestation that occurs within the endometrium of the horn of a unicornuate or bicornuate uterus, whereas an interstitial pregnancy occurs within the uterus at the junction of the uterus and the proximal part of the fallopian tube [1-3]. The traditional treatment for interstitial pregnancy is cornual resection by laparotomy or hysterectomy. This case describes a cornual heterotopic gestation occurring as a first pregnancy where both. Jansen RP, Elliott PM. By definition, a cornual pregnancy refers to the implantation and development of a gestational sac in one of the upper and lateral portions of the uterus. Some sources use "interstitial" and "cornual" synonymously, while others reserve "cornual" for gestations in bicornuate or septate uteri; others distinguish interstitial from angular pregnancy, while in practice, many physicians are unfamiliar with the latter designation. Although it is often used interchangeably with interstitial pregnancy, cornual pregnancy specifically refers to the implantation of a blastocyst within the cornua of a bicornuate or septate uterus (, 20,, 32). The term "cornual pregnancy" is often used interchangeably with "interstitial pregnancy." In fact, it refers to a similar but different condition. Interstitial pregnancy Least controversial is the term "interstitial ectopic pregnancy", one which we would pose should remain in the lexicon. We did not find any significant differences in mean patient age, mean gestational age, preoperative hemoglobin levels, or mean and median levels of serum β-hCG between the cornual resection and cornuotomy groups. proposed the following ultrasound diagnostic criteria for a cornual pregnancy: there is a single interstitial portion of the fallopian tube in the main uterine cavity; Rupture of a cornual pregnancy also results . As clearly demonstrated in Fig. Interstitial pregnancy: gestational sac in interstitial portion of fallopian tube. It results in no lateral displacement of the round ligament [2]. The term interstitial pregnancy is sometimes interchangeably used with cornual pregnancy, but the latter specifically refers to the presence of a gestational sac within a rudimentary uterine horn, a unicornuate uterus , cornua of a bicornuate uterus or septate uterus.

Through reviewing the local databases, 16 cases of cornual heterotopic pregnancies following IVF/ICIS and embryo transfer were reviewed. In a cornual ectopic pregnancy, the pregnancy will be detected in 1 of these limbs.2 Critical ultrasound findings in this condition include a pregnancy that is seen to the periphery of the uterus, with an EMM that measures less than 5 to 8 mm in either the sagittal or coronal planes.3,4 Owing to this Traditionally, interstitial pregnancies were treated with cornual resection or hysterectomy via laparotomy.

Constitutes 20% of all deaths from ectopic pregnancy. In the past, an interstitial pregnancy was managed conservatively until over 12 weeks on the premise that the uterine muscle protected against early rupture. An interstitial pregnancy (IP) occurs when the blastocyst implants in the most proximal section of the fallopian tube (called the interstitial portion), which is within the myometrium [].This interstitial section of the fallopian tube is approximately 0.7-mm wide and 1-2-cm long [].IPs may be incorrectly referred to as 'cornual' or 'angular' pregnancies. However, the identification of a cornual ectopic pregnancy should only be used for pregnancies which occur in a rudimentary uterine horn, a unicornuate uterus (), the cornual region of a septate uterus (), a bicornuate uterus or a uterus didelphys. Ectopic Pregnancy and Salpingectomy Lisa C. Hickman Jeffrey M.

An interstitial pregnancy is a uterine but ectopic pregnancy; the pregnancy is located outside the uterine cavity in that part of the fallopian tube that penetrates the muscular layer of the uterus. Rare Type Of Ectopic Pregnancy An article published in The Obstetrician & Gynaecologist (TOG) talks about how to treat women with cornual (interstitial) pregnancies. Cornual pregnancies often pose a diagnostic and therapeutic challenge with a significant high morbidity and mortality as a result of massive intraperitoneal bleeding. Emergency laparotomy revealed in 48 hours.

Cornual implantation describes those in the upper and lateral uterine cavity, whereas interstitial denotes those implanted within the proximal intramural portion of the tube. This is an unusual type of ectopic pregnancy in which the fertilized egg implants inside the part of the fallopian tube that is sunk into the wall of the uterus. An interstitial pregnancy is an ectopic or extrauterine pregnancy which occurs when implantation is within the myometrium of interstitial part of the fallopian tube.
