IntroductionHeterotopic pregnancy (HP) is characterized by the existence of intrauterine and ectopic pregnancies occurring simultaneously(1). This is a rare yet serious condition that can be spontaneous or resultant from assisted reproductive technology (ART)(2). While spontaneous HP has a reported frequency of 1 in 50,000 to 1 in 10,000(3, 4), ART-related cases of HP have been estimated to occur in 0.2%-1% of patients(5). Heterotopic Cesarean scar pregnancy (HCSP) involves the occurrence of a Cesarean scar pregnancy (CSP) accompanied by intrauterine pregnancy (IUP), which poses a high risk of catastrophic complications such as uterine rupture and massive hemorrhage(6, 7, 8). An extremely low incidence of HCSP has been reported during spontaneous cycles. Nevertheless, due to the rising occurrence of Cesarean section delivery and the expanding recourse to ARTs, the prevalence of HCSP is anticipated to increase(9, 10, 11). Due to the considerable risk for fetal and maternal morbidity and mortality, timely and precise diagnosis of HCSP is vital(12). The principal investigative approach that holds the greatest significance involves sonographic and Doppler flow-based evaluations(13). In the management of HCSP, preserving the coexistent presents a significant challenge. Guidelines for managing HCSP while preserving the IUP are not universally standardized due to the rarity of this condition(14). The typical method is to terminate the implantation located within the scarred area, if deemed necessary, at the potential expense of terminating the IUP(7). The available literature reveals a range of techniques for managing this condition, with medical and surgical approaches being two distinct options. The surgical interventions, which may involve laparoscopic or hysteroscopic excision of the masses, have been linked with potential complications like the loss of pregnancy and preterm delivery. In our research, we detail a case of HCSP, which was addressed through a combination of exploratory laparotomy and dilation and curettage (D&C) procedures.
