Outcome of pelvic arterial embolization for postpartum hemorrhage: A retrospective review of 117 cases. Obstet Gynecol Sci 2014; 57:17-27. [PMID: 24596814 PMCID: PMC3924745 DOI: 10.5468/ogs.2014.57.1.17] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2013] [Revised: 07/10/2013] [Accepted: 07/23/2013] [Indexed: 11/30/2022] Open
Abstract
Objective The aim of this study was to evaluate indications, efficacy, and complications associated with pelvic arterial embolization (PAE) for postpartum hemorrhage (PPH). Methods We retrospectively reviewed the medical records of 117 consecutive patients who underwent PAE for PPH between January 2006 and June 2013. Results In our single-center study, 117 women underwent PAE to control PPH refractory to conservative management including uterine massage, use of uterotonic agents, surgical repair of genital tract lacerations, and removal of retained placental tissues. Among 117 patients, 69 had a vaginal delivery and 48 had a Cesarean section. The major indication for embolization was uterine atony (54.7%). Other causes were low genital tract lacerations (21.4%) and abnormal placentation (14.5%). The procedure showed a clinical success rate of 88.0% with 14 cases of PAE failure; there were 4 hemostatic hysterectomies and 10 re-embolizations. On univariate analysis, PAE failure was associated with overt disseminated intravascular coagulation (P=0.009), transfusion of more than 10 red blood cell units (RBCUs, P=0.002) and embolization of both uterine and ovarian arteries (P=0.003). Multivariate analysis showed that PAE failure was only associated with transfusions of more than 10 RBCUs (odds ratio, 8.011; 95% confidence interval, 1.531-41.912; P=0.014) and embolization of both uterine and ovarian arteries (odds ratio, 20.472; 95% confidence interval, 2.715-154.365; P=0.003), which were not predictive factors, but rather, were the results of longer time for PAE. Three patients showed uterine necrosis and underwent hysterectomy. Conclusion PAE showed high success rates, mostly without procedure-related complications. Thus, it is a safe and effective adjunct or alternative to hemostatic hysterectomy, when primary management fails to control PPH.

Abstract
PURPOSE To evaluate clinical outcomes of failed pelvic arterial embolization (PAE) and determine predictive factors associated with this failure in the treatment of postpartum hemorrhage (PPH). MATERIALS AND METHODS This retrospective study included all consecutive patients who underwent PAE for life-threatening PPH between March 2004 and January 2011 at a tertiary-care center. Medical records and imaging studies were reviewed to identify cases of failed PAE and their clinical outcomes. Multiple parameters were compared between the failed and successful PAE groups, and multivariate analysis was performed to determine the predictive factors associated with failed PAE. RESULTS PAE was performed in 257 patients (mean age, 32 y; range, 20-40 y). A total of 24 cases of PAE involved a failure to achieve hemostasis (9.3%). Patients in the failed PAE group experienced more major complications than those in the successful PAE group (37.5% [nine of 24] vs 9.4% [22 of 233]). Factors more frequently found in failed PAE included hemodynamic instability, hemoglobin level lower than 8g/dL, disseminated intravascular coagulation (DIC), and extravasation detected on angiography. After multivariate analysis, DIC emerged as the only significant predictive factor (odds ratio, 6.569; 95% confidence interval, 1.602-26.932; P = .009). CONCLUSIONS PAE is an effective treatment for medically intractable PPH. However, PAE failed in a high percentage of patients and was commonly associated with major complications. DIC was the only significant predictor of failed PAE.

Abstract
PURPOSE To evaluate the efficacy and safety of transcatheter arterial embolization of the pelvic arteries for the treatment of postpartum hemorrhage (PPH) associated with cesarean section compared with vaginal delivery. MATERIALS AND METHODS A retrospective analysis of 176 patients undergoing transcatheter arterial embolization of the pelvic arteries for PPH from January 2006 through August 2011 was conducted at two institutions. The mean patient age was 33.9 years (range, 24-46 years). Data including delivery details, hematology and coagulation results, embolization details, and clinical outcomes were collected. Technical success was defined as cessation of bleeding on angiography or angiographically successful embolization of the bleeding artery. Clinical success was defined as the obviation of repeated embolization or surgical intervention. RESULTS The technical success rate was 98.8% (n = 174), and the clinical success rate was 89.7% (n = 158). Among 176 patients, 71 had cesarean sections, and 105 underwent normal vaginal deliveries. Of the 105 patients who underwent normal vaginal deliveries, 11 (10.5%) required repeat embolization or surgical intervention. Of the 71 patients who had cesarean sections, 7 (9.8%) required repeat embolization or surgical intervention. The clinical success rate and complication rate were not related to the mode of delivery. All women resumed menses after transcatheter arterial embolization, and most (n = 125) described their menses as unchanged. Subsequent spontaneous pregnancies occurred in 13 women. CONCLUSIONS The cesarean mode of delivery is not a predictor of poorer outcomes of transcatheter arterial embolization; however, further study is needed to clarify this relationship.

Abstract
Percutaneous vascular embolization is a useful therapeutic option for a wide range of gynecologic and obstetric abnormalities. Transcatheter embolization procedures performed with the use of radiologic imaging for guidance are minimally invasive and may obviate surgery, thereby decreasing morbidity and mortality and safeguarding the patient's future fertility potential. To integrate this treatment method optimally into patient care, knowledge is needed about the clinical indications for therapeutic embolization, the relevant vascular anatomy, technical considerations of the procedure, and the potential risks and benefits of embolization. The most well-known and well-studied transcatheter embolization technique for treating a gynecologic-obstetric condition is uterine fibroid embolization. However, the clinical indications for transcatheter embolization are much broader and include many benign gynecologic conditions, such as adenomyosis and arteriovenous malformations, as well as intractable bleeding due to inoperable advanced-stage malignancies. Uterine artery embolization may be performed to prevent or treat bleeding associated with various obstetric conditions, including postpartum hemorrhage, placental implantation abnormality, and ectopic pregnancy. Embolization of the uterine artery or the internal iliac artery also may be performed to control pelvic bleeding due to coagulopathy or iatrogenic injury, and ovarian vein embolization has been shown to be effective for the management of pelvic congestion syndrome. The article discusses these and other gynecologic and obstetric indications for transcatheter embolization, provides detailed descriptions of imaging findings before and after embolization, and reviews procedural techniques and outcomes.

Abstract
PURPOSE To evaluate the safety and efficacy of pelvic arterial embolization (PAE) for the treatment of primary postpartum hemorrhage (PPH) and to determine the factors associated with clinical outcomes. MATERIALS AND METHODS This retrospective single-center study was institutional review board approved, and informed consent was waived. Outcomes were analyzed in 251 patients who underwent PAE for primary PPH between January 2000 and February 2011. Mode of delivery, causes of bleeding, detailed laboratory and treatment records, and clinical outcomes were recorded. Clinical success was defined as cessation of bleeding after initial session of PAE without the need for additional PAE or surgery. Univariate and multivariate analyses were performed to determine the factors related to clinical outcomes. RESULTS The clinical success rate was 86.5% (217 of 251). Among the 34 failed cases, 12 underwent repeat PAE, 16 underwent additional surgery, and three recovered with conservative management. Overall bleeding control was achieved in 98.0% (246 of 251) of the patients. Overall mortality was 2% (five of 251) after the first (n = 3) or second (n = 1) session of PAE or additional surgery (n = 1). Among the 113 patients with long-term follow-up, 110 (97.3%) maintained a regular menstrual cycle and 11 had successful pregnancies. Univariate analysis showed that cesarean section delivery, disseminated intravascular coagulation (DIC), and massive transfusion of more than 10 red blood cell units were related to failed PAE. Multivariate analysis showed that DIC (odds ratio, 0.36; P = .04) and massive transfusion (odds ratio, 0.10; P < .001) were significantly related to clinical failure. CONCLUSION PAE is safe and effective for managing primary PPH. Patients with DIC and massive transfusion were likely to have poor results after PAE.

Abstract
PURPOSE To evaluate the efficacy and safety of superselective embolization of the uterine arteries in a postpartum hemorrhage. MATERIALS AND METHODS Between November 2004 and January 2011, a total of 44 consecutive women (median ± standard deviation age 34 ± 3 years, range 23-41 years) were referred to our institution for postpartum intractable hemorrhage management. All patients were embolized with a microcatheter that was placed deep into the uterine arteries upstream of the cervical arteries. The embolic agent was a mixture of contrast medium and 5 × 5 × 5 cm pieces of gelfoam (Gelita-Spon) modified into a gelatin emulsion as follows: rapid mixing through a three-way stopcock with two 2.5-ml syringes. A 1-ml syringe was used for injection. One month after embolization, all patients underwent magnetic resonance imaging and clinical examination. RESULTS Technical and clinical success was obtained in all cases. Thirty-five patients experienced bleeding related to poor retraction of the uterus, 7 patients because of a tear of the cervix and 2 because of a vaginal hematoma. Pre- and postembolization red blood cell transfusions were (mean ± standard deviation [SD]) 6 ± 1.2 (range 3-8) U and 2 ± 0.7 (range 2-4) U, respectively. One-month magnetic resonance imaging follow-up revealed no sign of ischemic myometrium or necrosis, and no instances of uterine rupture and no pelvic vein thrombosis. Incidental findings included two small intramyometrial hematic collections. All uterine arteries were patent via magnetic resonance angiography. Seventeen patients had concomitant fibroids, all of which appeared hypovascular. CONCLUSION This technique permits good, safe clinical results with no marked damage to the uterine arteries or the uterus itself.

Abstract
We report a case of a woman in whom uterine arterial embolization was performed using absorbable gelfoam particles for control of refractory postpartum hemorrhage. Ten days after delivery, the woman experienced high fever and low abdominal pain. Histologic findings after hysterectomy were consistent with uterine necrosis and acute suppurative myometritis.

Abstract
OBJECTIVE To assess the role of MRI in diagnosis and predicting clinical outcome in women with retained placental tissue. PATIENTS AND METHODS Eleven patients with pathologically proven RPT were retrospectively studied. All underwent MRI. The following MRI parameters of RPT were studied: size, signal intensity on T1- and T2-weighted images, enhancement pattern on dynamic study, extent of attachment to the uterine myometrium, and myometrial thickness at the attachment site. Clinical reports were reviewed and MRI findings were compared with respect to outcome. RESULTS RPT diameter varied from 30 to 102 mm. On T2-weighted images, 10 cases showed high intensity, while on T1-weighted images, seven cases showed high intensity. Nine cases were hypervascular. The myometrium was thinner at the attachment side than at the opposite side. All five cases in which RPT was delivered spontaneously showed an attachment area of less than a semicircle, hence broad attachment appears to impede detachment and necessitate additional therapy. After uterine arterial embolization, two patients showed complete infarction of RPT on enhanced MRI. CONCLUSION MRI is useful for diagnosis and follow-up of RPT. The evaluation of extent of RPT attachment to the myometrium and vascularity on MRI can help the clinical assessment.
