Purpose Irreversible electroporation(IRE) is an emerging ablative therapy which has now been widely recognized. It is a kind of local treatment by causing cell apoptosis. Compared with IRE ablation performed at open surgery,CT-guided percutaneous IRE ablation is less invasive for the treatment of locally advanced malignant tumors(LAMT). The purpose of this study is to assess the safety and efficacy CT-guided percutaneous IRE for the treatment of LAMT. Methods Patients with unresectable LAMTs were treated with IRE under the CT guidance. Procedures were performed under general anesthesia and comprehensive blood and imagine baseline examinations were completed and recorded preoperatively. All these imaging and serological follow-up were rechecked immediately after procedures, at postoperative 7 days, 1 and 3 months to evaluate the safety and efficacy of IRE. Result IRE was performed in a total of 28 patients( including 21 pancreatic cancers,4 hilar cholangiocarcinomas and 3 retroperitoneal tumors) with unresectable malignant tumors. All the procedures were performed successfully. The postoperative 1 month CT/MRI images showed all the ablation areas were well-defined and with nonenhancement. 9 patients suffered abdominal pain and distension, 4 patients developed nausea and intermittent vomiting. 3 patients had peripancreatic exudation. Mesenteric and portal venous thrombosis was found on MRI images in 4 patients.1 patient developed retroperitoneal infection. Conclusion CT-guided percutaneous IRE is a safe and effective procedure in patients with local advanced malignant tumors and may represent a new technological option in the treatment and multimodality management of these diseases.

平片密度分辨率较低,发现肺部结节性病变的钙化较CT少见,尤其在肺癌中,CT由于具有较高的密度分辨率,是DR平片的数倍, 故比传统的DR平片检查能更多的发现肺内孤立性结节中的钙化,本文旨在研究、分析孤立性肺结节内的钙化灶多少、大小、形态、钙化程度(钙化灶密度的高低)及钙化灶在结节内的分布特征,综合分析、判断,为结节的良、恶性的鉴别诊断提供更有价值的信息。
