A prospective evaluation and management of different types of placenta praevia using parallel vertical compression...

The rising tendency of cesarean sections will lead invariably to more complications such as placenta praevia. The aim of our study was to evaluate the utility of parallel vertical compression suture to preserve uterus in cases of placenta praevia, and to propose a rational approach of these problematic cases, according to their grade of myometrial invasion.We prospectively included 95 consecutive cases diagnosed with placenta praevia (group1 [Gr1]) where we used parallel compression suture and compared to retrospectively analyzed 100 consecutive cases managed without using this technique (group 2 [Gr2]). We differentiated the types of placenta praevia according to their invasion in myometrium because this parameter appreciates best their degree of severity, so we had 4 Grs: simple praevia (no adherent), accreta, increta, and percreta. All patients underwent ultrasound evaluation before surgery. Cesarean section was planned at 35 to 36 weeks. The main goal was to preserve the uterus whenever was possible. After opening the peritoneal cavity, we first inspected the lower segment and bladder. If no signs of engorged and tortuous vessels we dissected first the bladder and then performed a transverse hysterotomy, removed the placenta and placed 2 parallel vertical sutures on the lower segment below the hysterotomy incision through the entire thickness of both uterine walls. In cases of massively engorged vessels we dissected the bladder after infant delivery and made a transverse uterine incision slightly higher. We measured the amount of blood loss and performed three postoperative ultrasound exams, on day 2, 4 and at 6 to 8 weeks.Using this technique, we were able to preserve the uterus in 98.33% of Gr1 versus 78.47% from Gr2 of simple placenta praevia, in 88.23% in Gr1 compared to 42.86% in Gr2 of placenta accreta, only in 14.28% of increta type and in none (0%) of the 2 cases with placenta percreta.The simplified compression technique for hemostasis and preserving uterus in cases of simple placenta praevia and accreta is easy to perform without special surgical skills and is rapid. There are no short and long-time complications related to the technique. In cases of placenta increta the problem is not that this technique is unsuccessful but getting to that point to place the sutures is difficult. In severe cases of placenta percreta, unfortunately, the hysterectomy remains the treatment of choice.
