Shape: accessory ostium & tubal diverticulum predispose to ectopic pregnancy. In fallopian tube The isthmus is a small region, only about 2 cm (0.8 inch) long, that connects the ampulla and infundibulum to the uterus.

The fallopian tubes are any vital part of the female reproductive system as they transport the eggs from the ovaries to the uterus.. Gestational sac adjoining to the unicornuate uterus with a vascular pedicle. The paramesonephric ducts caudally unite in the midline and eventually forms the uterus and the superior vagina. Therefore, an interstitial ectopic pregnancy is defined as pregnancy implanted in the interstitial portion of the fallopian tube that is within the muscular wall of the uterus, lateral to the round ligament of the uterus (Figure 1) [1,2,10].

Interstitial ectopic pregnancy corresponds to an implantation of trophoblast in the interstitial portion of the fallopian tube, a tortuous segment with 0.7 mm in diameter and 1-2 cm in length covered by a thin continuous layer of myometrium. In the 4th or 6th week, the Mullerian ducts or paramesonephric ducts take form in the female embryos because there is no anti-mullerian hormone (AMH). Cornual pregnancies often pose a diagnostic and therapeutic challenge with a significant high morbidity The part of fallopian tube closest to the ovary is infundibulum.

Surgical methods to remove the pregnancy include cornual evacuation, incision of the cornua with removal of the pregnancy (cornuostomy), resection of the cornual area or a cornual wedge resection, typically combined with an ipsilateral salpingectomy, and hysterectomy. The second segment is the ampulla, which becomes more dilated in diameter and is the most common site for fertilization. In the presence of peritoneal fluid or contrast material, the fallopian tubes appear as paired, thin, serpentine juxtauterine structures extending either anteriorly or posteriorly into the cul-de-sac. Anatomy . The infundibulum leads to the ampulla where the fertilisation takes place. Intramural (interstitial) part, which is located within the myometrium of the uterus, is 1 cm long and 0.7 mm wide. The fallopian tube is divided into five anatomic segments (from lateral to medial, through the path of an ovum after ovulation): fimbriae: ~25 finger-like projections that drape over the ovary, the ovarian fimbriae are longer than the others and are attached to the tubal pole of the ovary, infundibulum: a funnel-shaped lateral part that drapes over the ovary with the fimbriae emanating from it, it opens into the peritoneal cavity at the abdominal ostium, ampulla:the widest and longest section, forming over half the length, it is the most established location of fertilization, isthmus:immediately lateral to the uterus, it is the narrowest segment, as its name suggests, interstitial or intramural segment: the section within the myometrium. It is the site of fertilization. The part of the Fallopian tube that is located in the uterine wall and connects the remainder of the tube to the endometrial cavity is called its "interstitial" part, hence the term "interstitial pregnancy"; it has a length of 12cm and a width of 0.7cm.

FIPAT.library.dal.ca. 6 Is the infundibulum part of the fallopian tube? The fallopian tube serves as a passageway for the gamete to the ovary and the uterus. The fallopian tube(TA: tuba uterina 8), also known as the uterine tube or less commonly the oviduct, is a paired hollow tube that bridges between each ovary and the uterus and functions to convey the mature ovum from the former to the latter. Muscle is sensitive to sex steroids, and thus peristalsis is greatest when oestrogen levels are high. Typical symptoms of an interstitial pregnancy are the classic signs of ectopic pregnancy, namely abdominal pain and vaginal bleeding.
