CT-guided accurate localization of small pulmonary nodule with memory alloy coil before thoracoscopic resection / 中国介入影像与治疗学

Objective: To observe the value of CT-guided accurate localization of small pulmonary nodule with memory alloy coils before video-assisted thoracoscopic surgery (VATS). Methods: Totally 92 patients (102 small pulmonary nodules) underwent localization of small pulmonary nodules with memory alloy coils before VATS were enrolled. VATS was performed within 24 h after localization. The localization effect and complications were observed. Results: The success rate of localization of 102 small pulmonary nodules was 98.04% (100/102), and the operation time of localization for each lesion ranged 8 min to 45 min, with the average time of (17.26±5.92)min. The memory alloy coils of 2 patients took off from lung tissue and remained in the chest wall in VATS. After localization, the incidence of small amount of pneumothorax was 10.78% (11/102), of small amount alveolar hemorrhage was 12.75% (13/102), whereas the patients had no symptom and untreated. VATS was successfully performed for 102 small pulmonary nodules without conversion to thoracotomy. Conclusion: CT-guided accurate localization of small pulmonary nodule with memory alloy coils before VATS is effective and safe.

Uterine artery embolization in cesarean scar pregnancy: safe and effective intervention / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Cesarean scar pregnancy (CSP) is a very rare but life-threatening entity and there is no optimal management strategy. Here we report a successfully conservative treatment of CSP.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 54 women with CSP, who underwent uterine artery embolization between January 2007 and September 2012 at the Peking University People's Hospital. We evaluated the clinical outcomes, the technique and the complications of uterine artery embolization.</p><p><b>RESULTS</b>Of the 54 patients, 2 patients with hemorrhage after induced abortion received bilateral uterine artery embolization treatment alone, and 52 patients underwent suction curettage after bilateral uterine artery embolization. All 54 women were successfully cured, without any severe complications, and uterine function was restored. During the follow-up, one patient had accidental normal interuterine pregnancy and received induced abortion during the first trimester.</p><p><b>CONCLUSION</b>[corrected] Uterine artery embolization combined with suction curettage is an effective and safe conservative treatment for cesarean scar pregnancy.</p>
