目的：探讨胸部肿瘤手术切除前行胸廓内动脉栓塞的应用价值和安全性。方法13例胸部肿瘤均经胸部CT和／或M RI确诊，包括孤立性纤维性肿瘤7例，神经内分泌肿瘤2例，内胚窦瘤2例，结节硬化型霍奇金淋巴瘤胸腺瘤1例，恶性外周神经鞘瘤1例，寻找其可能供血动脉造影，对参与供血的胸廓内动脉用PVA颗粒和明胶海绵颗粒进行栓塞，介入术后1～3 d行胸部肿瘤切除术。结果13例胸部肿瘤中动脉造影可见7例胸廓内动脉为肿瘤主要供血动脉，肿瘤主要位于前胸部，并与前、侧胸壁粘连，造影表现为胸廓内动脉主干增粗，远端分支增多、迂曲、杂乱，供血范围与肿瘤阴影相重叠。栓塞后未发生明显并发症，外科手术中失血量少，肿瘤切除完整，手术时间缩短。结论前胸部肿瘤，尤其是有粘连者，切除术前栓塞胸廓内动脉对手术切除有良好的辅助作用，是一种安全有效的治疗方法。%Objective To discuss the clinical application value and safty of interventional embolization of ITA before surgical resection of thoracic tumors .Methods 1 3 patients of thoracic tumors were diagnosised by CT and/or MRI .They were given thoracic artery angiography and the arteries that supplied thoracic tumors were given interventional embolization with PVA and gelatin sponge .Surgical resection of thoracic tumors were given in 1 ~3 days after embolization .Results The angiography of 1 3 patients showed that ITA is the main artery of thoracic tumors in 7 patients which tumors were located in the anterior chest and adhered to the front side of the chest wall .Characters of angiography of 7 patients showed that enlargement and circuity of feeding arteries ,increasing tumor vessels ,and staining of the tumor .None serious complication appearance .Blooding quantities were obviously reduced ,tumors were completely resected and operation time was shortened of surgical resection .Conclusion Pro -operation interventional embolization of ITA of tumors which were located in the anterior chest and adhered to the front side of the chest wall has obvious help to surgical resection .It is a safe and effective way for surgical resection .
