INTRODUCTIONPregnancies in women with thrombophilia are associated with a higher risk of obstetric complications. We systematically reviewed the findings of relevant randomised controlled trials (RCTs) with the aim of investigating the effectiveness of low-molecular-weight heparins (LMWHs) in pregnant women with inherited thrombophilic disorders and its effect on the incidence of live births in these patients.
METHODSThe MEDLINE-PubMed and Cochrane CENTRAL databases from 2000 to 2010 were searched using a combination of keywords, including low-molecular-weight heparin, enoxaparin, pregnancy, live birth and thrombophilia. Studies were included if they were RCTs assessing the effect of anticoagulant treatment on live birth rates in women with a history of miscarriage without apparent causes other than thrombophilic disorder. Interventions included LMWH, with or without aspirin, aspirin alone or placebo controlled for the prevention of adverse pregnancy outcome.
RESULTS43 articles with seven RCTs were retrieved following the initial search, of which four studies had to be excluded as they assessed thromboembolic events as the final outcome (n = 1), focused on idiopathic recurrent miscarriages (n = 1), compared efficacy and safety of two doses of enoxaparin (n = 1), and examined patients with or without thrombophilic disorder (n = 1). Pooled data from the remaining three RCTs showed no significant difference in the improvement of live birth rates following LMWH interventions (p = 0.15).
CONCLUSIONAt present, the use of LMWH in women with inherited thrombophilia with recurrent pregnancy loss is not indicated. Large randomised placebo-controlled trials are further needed to prove the effectiveness of LMWH in these patients.

Haemangioma of the retroperitoneal space is a rare benign capillary malformation, which can grow significantly in pregnancy due to the multiple associated cardiovascular changes. We herein describe the case of a pregnant woman with an extensive right retroperitoneal haemangioma extending from the level of the renal hilum, across the lateral anterior abdominal wall and into the thigh. We also highlight the challenges faced in the management of the patient's delivery process. To the best of our knowledge, this is the first case of such nature and severity described in the English literature.

There has been growing concern surrounding the use of unconfined power morcellation in laparoscopic surgeries for uterine leiomyoma due to its associated risks and long-term clinical sequelae, including parasitic leiomyomas and disseminated peritoneal leiomyomatosis (DPL). We present a case of DPL resulting from previous laparoscopic morcellation and a review of the existing literature. DPL is a potentially devastating consequence of unconfined laparoscopic morcellation in the surgical management of uterine fibroids. A multidisciplinary approach is recommended in the management of DPL, especially in cases of multivisceral involvement. Clinical caution ought to be exercised when using power morcellators; when unavoidable, confined laparoscopic morcellation offers a promising mitigation and should be adopted if practicable.
