In 95 % of cases, implantation occurs in the Fallopian tube - most often in the ampullary portion. Less frequent locations include the uterine horn, cervix, ovary, peritoneal surface and, in the case of Caesarean section scars, the isthmic myometrium. Ectopic pregnancy accounts for 1 to 2 % of all pregnancies, and is the leading cause of maternal mortality in the first trimester of pregnancy in high-income countries, due to the risk of tubal rupture leading to massive intra-abdominal hemorrhage and hypovolemic shock. In Quebec, the incidence is around 12 cases per 1,000 pregnancies. Diagnosis is based on the clinical triad of pelvic pain, metrorrhagia and amenorrhea, combined with serial beta-hCG measurement and transvaginal ultrasound. Depending on the hemodynamic status, location and characteristics of the ectopic pregnancy, management may be medical (methotrexate), surgical (salpingostomy or salpingectomy) or conservative (expectant monitoring in EGs with spontaneous resolution). Future fertility depends on the speed of diagnosis and choice of treatment.\n <\/div>\n\n <h2>Pathophysiology, risk factors, and locations<\/h2>\n <ul class=\"co-list\">\n <li><strong>Mechanisms of ectopic implantation and pathophysiology:<\/strong> normal migration of the fertilized ovum: after fertilization in the ampullary portion of the tube \u2192 the zygote is transported to the uterine cavity in 3-5 days by ciliary motility + tubal peristaltic contractions \u2192 implantation in the endometrium around D6-J7;

In 95 % of cases, implantation occurs in the Fallopian tube - most often in the ampullary portion. Less frequent locations include the uterine horn, cervix, ovary, peritoneal surface and, in the case of Caesarean section scars, the isthmic myometrium. Ectopic pregnancy accounts for 1 to 2 % of all pregnancies, and is the leading cause of maternal mortality in the first trimester of pregnancy in high-income countries, due to the risk of tubal rupture leading to massive intra-abdominal hemorrhage and hypovolemic shock. In Quebec, the incidence is around 12 cases per 1,000 pregnancies. Diagnosis is based on the clinical triad of pelvic pain, metrorrhagia and amenorrhea, combined with serial beta-hCG measurement and transvaginal ultrasound. Depending on the hemodynamic status, location and characteristics of the ectopic pregnancy, management may be medical (methotrexate), surgical (salpingostomy or salpingectomy) or conservative (expectant monitoring in EGs with spontaneous resolution). Future fertility depends on the speed of diagnosis and choice of treatment.\n <\/div>\n\n <h2>Pathophysiology, risk factors, and locations<\/h2>\n <ul class=\"co-list\">\n <li><strong>Mechanisms of ectopic implantation and pathophysiology:<\/strong> normal migration of the fertilized ovum: after fertilization in the ampullary portion of the tube \u2192 the zygote is transported to the uterine cavity in 3-5 days by ciliary motility + tubal peristaltic contractions \u2192 implantation in the endometrium around D6-J7;
