Safety and efficacy of thromboprophylaxis using enoxaparin sodium after cesarean section: A multi-center study in Japan.

OBJECTIVE: Pulmonary embolism (PE) is the leading cause of maternal death in developed countries, and the prevention of venous thromboembolism (VTE) is a pivotal part of current obstetric care. This study evaluated the safety and efficacy of enoxaparin sodium for thromboprophylaxis after cesarean section (C/S), and analyzed the risk factors associated with VTE. MATERIALS AND METHODS: One hundred and forty-three women deemed to be at high risk of postoperative deep vein thrombosis (DVT) were enrolled between January 2011 and May 2012 in seven institutions in Japan. Subcutaneous administration of enoxaparin 4000 units/d was initiated 24-36 hours after C/S for 5 days. Adverse events, based on the Common Terminology Criteria for Adverse Events, Version 4, were recorded. The diagnoses of PE and DVT were made on clinical signs. Venous ultrasonography in the lower extremities was performed in 102 patients. The association between VTE and various risk factors was evaluated using univariate analysis. RESULTS: There were 10 (7.0%) Grade 1 adverse events: elevated aspartate aminotransferase or alanine aminotransferase levels in eight patients, chest pain in one patient, and subcutaneous hematoma in one patient. No patients showed clinical signs of PE and/or DVT. Among 102 patients who underwent venous ultrasonography, thrombus was detected in unilateral soleus veins in four (3.9%) patients. A body mass index (BMI) ≥ 25 kg/m(2) before pregnancy was associated with asymptomatic DVT. CONCLUSION: The current study demonstrates the safety and efficacy of enoxaparin for thromboprophylaxis after C/S. Further studies are required to determine the best method of preventing asymptomatic DVT.

Predictive factors related to the efficacy of pelvic arterial embolization for postpartum hemorrhage: a retrospective analysis of 21 cases.

OBJECTIVE: This retrospective study aimed to determine the predictive factors for the efficacy of pelvic arterial embolization for postpartum hemorrhage. MATERIALS AND METHODS: Twenty-one patients who underwent pelvic arterial embolization for postpartum hemorrhage of >1000 mL between September 2006 and September 2011 were enrolled in this study. The patients were divided into two subgroups according to the blood loss and time from the end of pelvic arterial embolization to complete hemostasis: good-response (16 patients) and poor-response groups (5 patients). The following predictive factors were compared between the groups: (1) patient characteristics; (2) blood loss; (3) time between delivery (or onset of bleeding) and pelvic arterial embolization; (4) obstetrical disseminated intravascular coagulation score comprising clinical background, clinical signs, and laboratory data; (5) individual disseminated intravascular coagulation score; (6) shock index; and (7) laboratory data including platelet count, prothrombin time-international normalized ratio, fibrinogen, fibrin degradation products, and antithrombin-III at the time of pelvic arterial embolization. RESULTS: In the poor-response group, the obstetrical and individual disseminated intravascular coagulation scores and prothrombin time-international normalized ratio were higher than those in the good-response group (p < 0.05). Platelet count, fibrinogen, and fibrin degradation products were lower than those in the good-response group (p < 0.05). All obstetrical disseminated intravascular coagulation scores in the poor-response group were >9 points. CONCLUSION: The efficacy of pelvic arterial embolization is related to the presence or absence of coagulation disorders. When the obstetrical disseminated intravascular coagulation score is high (>9 points), the efficacy may be poor.

Follow up of surgical repair of female pelvic floor disorders by a mailed questionnaire.

BACKGROUND: This study was conducted to determine whether surgical repair of pelvic prolapse enhances patients' quality of life (QOL) in the long term. METHODS: A total of 91 patients (median age, 68.0 years) with pelvic prolapse including cystoceles underwent bladder neck suspension with anterior/posterior colporrhaphy between 1997 and 2003. Postoperative QOL was longitudinally assessed by three disease-specific items (sensation of vaginal bulging, obstructive symptoms, urinary incontinence), and one overall health-related QOL (HR-QOL) item. RESULTS: A longitudinal study demonstrated that a significant improvement in these symptoms was sustained at a median follow up of 65.5 months, although poor HR-QOL was significantly higher in patients whose age was more than 70 years at surgery (P = 0.0234, Fisher's test). Multivariate analysis revealed update urinary incontinence, update obstructive symptoms, and basic comorbidity to be independent prognostic factors for predicting postoperative moderate-to-poor HR-QOL. CONCLUSIONS: Longer follow up with adequate assessment of patients' QOL may be crucial for the management of postoperative patients, in particular those having basic comorbidity and aged 70 years or more at surgery.

Does surgical repair of pelvic prolapse improve patients' quality of life?

OBJECTIVES: The aims of this study were to evaluate the efficacy of surgical repair in patients with pelvic prolapse, and to assess the postoperative quality of life (QOL). METHODS: A total of 70 patients (mean age: 66.7 years) underwent transvaginal two-corner bladder neck suspension in combination with transvaginal hysterectomy (63 cases), and anterior with (49) or without (21) posterior colporrhaphy. The status of recurrence and complications were followed in all patients at a mean follow-up period of 32.0 months. Postoperative patients' quality of life (QOL) consisting of four items (sensation of vaginal bulging, urinary incontinence, difficulty to urinate, and health-related QOL) was assessed in 52 cases whose were followed at least two years (mean: 41.6 months, range: 24.3-69.1). RESULTS: Sixty-eight patients (97%) were recurrence-free. Nine of the 39 (23%) patients with difficulty to urinate before surgery had persistent symptoms postoperatively. Multivariate analysis revealed that cystometric abnormalities, voiding symptoms at seventh days after surgery, and weak detrusor contraction were independent prognostic factors for persistent voiding symptoms. As for the QOL, all items had significant improvement at 13 months after surgery as compared to baseline condition. A longitudinal study showed improvement of these symptoms sustained at least up to four years. CONCLUSIONS: This study suggests that surgical repair can achieve results with long-term durability as well as improving the QOL. In addition, assessment of the detrusor function may be needed for patients who complain difficulty to urinate in avoiding persistent such symptoms.
