Purpose
To evaluate the efficacy of pre-myomectomy uterine artery embolization with gelatin sponge particles to reduce operative blood loss and facilitate removal of fibroids.Materials and methods
This retrospective study included 33 women (mean age, 36 years; range, 24-45 years), of whom at least 18 wished to preserve fertility. They presented with at least one large myoma (mean diameter, 90 mm; range, 50-150 mm) and had undergone preoperative uterine artery embolization with resorbable gelatin sponge by unilateral femoral approach between December 2001 and November 2008. Clinical, radiological and surgical data were available for all patients. Mean haemoglobin levels before and after surgery were compared with Student's t-test.Results
No complication or technical failure of embolization occurred. The myomectomies were performed during laparotomy (25 cases) or laparoscopy (8 cases). Dissection of fibroids was easier (mean, 3 per patient; range, 1-11), with a mean operating time of 108 ± 50 min (range, 30-260 min). Bloodless surgery was the rule with a mean estimated peroperative blood loss of 147 ± 249 mL (range, 0-800 mL). Mean pre-(12.9 ± 1.3 g/dL) and post-therapeutic (11.4 ± 1.2 g/dL) haemoglobin levels were not statistically different (p > 0.05). There was no need for blood transfusion. None of the patients required hysterectomy. The mean duration of hospital stay was 7.5 ± 1.3 days (range, 3-12 days).Conclusion
Preoperative uterine artery embolization is effective in reducing intraoperative blood loss and improves the chances of performing conservative surgery. It should be considered a useful adjunct to myomectomy in women at high hemorrhagic risk or who refuse blood transfusion. 相似文献44.

Arginase serum levels were increased in human African trypanosomiasis patients and returned to control values after treatment. Arginase hydrolyzes l-arginine to l-ornithine, which is essential for parasite growth. Moreover, l-arginine depletion impairs immune functions. Arginase may be considered as a biomarker for treatment efficacy. 相似文献

Hepatic infarction is rare in hemolysis, elevated liver enzymes, and low platelets syndrome. We described a case of a 24-year-old
woman who was admitted at week 17 of pregnancy with an antiphospholipid syndrome. Magnetic resonance imaging was the imaging
modality of choice for diagnosing hepatic infarction, guiding treatment, ensuring the early detection of bleeding, and monitoring
liver recovery. 相似文献

Initially discovered in human melanoma, CD146/MCAM is expressed on many tumors and is correlated with cancer progression and metastasis. However, targeting CD146 remains challenging since it is also expressed on other cell types, as vessel cells, where it displays important physiological functions. We previously demonstrated that CD146 is shed as a soluble form (sCD146) that vectorizes the effects of membrane CD146 on tumor angiogenesis, growth and survival. We thus generated a novel monoclonal antibody, the M2J-1 mAb, which specifically targets sCD146, but not membrane CD146, and counteracts these effects. In our study, we analyzed the effects of sCD146 on the dissemination and the associated procoagulant phenotype in two highly invasive human CD146-positive cancer cell lines (ovarian and melanoma). Results show that sCD146 induced epithelial to mesenchymal transition, favored the generation of cancer stem cells and increased the membrane expression of tissue factor. Treatment of cancer cells with sCD146 in two experimental models (subcutaneous xenografting and intracardiac injection of cancer cells in nude mice) led to increased tumor dissemination and procoagulant activity. The M2J-1 mAb drastically reduced metastasis but also procoagulant activity, in particular by decreasing the number of circulating tumor microparticles, and blocked the relevant signaling pathways as demonstrated by RNA expression profiling experiments. Thus, our findings demonstrate that sCD146 mediates important pro-metastatic and procoagulant effects in two CD146-positive tumors. Targeting sCD146 with the newly generated M2J-1 mAb could constitute an innovative strategy for preventing dissemination and thromboembolism in many CD146-positive tumors. 相似文献
