Placenta accreta is the main cause of severe obstetric postpartum hemorrhage (PPH) and hysterectomy. Several hemostatic techniques have been performed in patients with placenta accreta to prevent PPH and reserve fertility. Abdominal aorta and pelvic arteries balloon occlusion are the only techniques which could be performed before cesarean section (CS) in patients who want to keep the fetus and reserve fertility. However, abdominal aorta and pelvic arteries balloon occlusion might lead to severe complications such as formation and rupture of pseudoaneurysm, angiorrhexis, etc.
We report a case diagnosed with pernicious placenta previa (PPP) combined with Rh(D) negative blood type, who was performed with bilateral common iliac arteries (CIA) balloon occlusion during CS. However, on the first day after CS, the patient caught sudden left-side lumbago and backache accompanied with palpitation and shortness of breath.
Formation and rupture of multiple pseudoaneurysms in left CIA.
Covered stent was inserted into the proximal part of the left CIA and the ipsilateral internal iliac artery was embolized by coil to prevent endoleak.
The patient recovered and discharged from hospital in stable condition without other complications 9 days after CS.
It is of paramount importance that obstetricians and radiologists correctly estimate the appropriate occlusion volume and pressure of pelvic arteries before CS to avoid formation and rupture of a pseudoaneurysm. And if the rupture of a pseudoaneurysm occurred, it should be quickly identified and treated with endovascular intervention.
胎盘植入是产科严重产后出血(PPH)和子宫切除术的主要原因。对于胎盘植入患者,已采用多种止血技术来预防PPH并保留生育能力。腹主动脉和盆腔动脉球囊闭塞是仅有的可在剖宫产(CS)前对希望保留胎儿并保留生育能力的患者实施的技术。然而,腹主动脉和盆腔动脉球囊闭塞可能会导致严重并发症,如假性动脉瘤的形成和破裂、血管撕裂等。
我们报告一例诊断为凶险性前置胎盘(PPP)合并Rh(D)阴性血型的患者,其在剖宫产期间接受了双侧髂总动脉(CIA)球囊闭塞术。然而,剖宫产术后第一天,患者突然出现左侧腰痛和背痛,并伴有心悸和呼吸急促。
左侧CIA多发假性动脉瘤形成并破裂。
在左侧CIA近端植入覆膜支架,并通过弹簧圈栓塞同侧髂内动脉以预防内漏。
患者恢复良好,剖宫产术后9天病情稳定出院,无其他并发症。
产科医生和放射科医生在剖宫产术前正确估计盆腔动脉的合适闭塞容量和压力以避免假性动脉瘤的形成和破裂至关重要。如果发生假性动脉瘤破裂,应迅速识别并用血管内介入治疗。
