为了探讨局部麻醉和模拟定位机引导在集束巨能刀治疗肺癌的射频治疗的适应证、治疗效果以及并发症的预防和处理,采用0.5%普鲁卡因局部浸润麻醉,模拟定位机引导下经皮穿刺集束巨能刀治疗肺癌46例。CT显示条索状瘢痕残余ll例,空洞形成或直径缩小32例,无变化1例,增大2例。治疗中患者均有不同程度的胸腔内热感及短时间内可以忍受的疼痛感。并发症包括气胸7例、皮下气肿5例、发热24例、咯血13例和慢性支气管炎急性发作4例。初步研究结果提示,集束巨能刀射频治疗周围型肺癌疗效满意,尤其适用于直径〈3cm的肿瘤。局部麻醉配合全身止痛药物应用可以很好地解决治疗中的疼痛问题,与全麻相比还具有省时省力、费用低的优势;对于周围型肺癌,模拟定位机引导经皮穿刺定位与CT引导相比,同样准确、安全,但操作更为方便。 相似文献

Tumor lysis syndrome, resulting from the abrupt release of intracellular ions into the blood stream due to sudden tumor cell death, is a serious complication of chemotherapy treatment. This syndrome occurs more frequently in hematologic malignancies and lymphomas. Its incidence in solid tumors is rare, but has a high mortality rate owing to the lack of prophylactic therapy to prevent this complication. We report a case of tumor lysis syndrome accompanied by death in a patient with extensive stage small cell lung cancer who was treated with cisplatin and etoposide, and review the risk factors associated with the syndrome in solid tumor patients who are likely to respond to chemotherapy. 相似文献

Recently, percutaneous radiofrequency (RF) ablation has been increasingly performed as a local treatment for lung malignancies.
In RF ablation, the application of radiofrequency agitates ions in the tissues surrounding the electrode, causing them to
fluctuate at high speed, and this generates frictional heat. The generated heat coagulates the tissues. Puncture is carried
out under computed tomography (CT) guidance in the same manner as that for needle biopsy. In animal studies, it was speculated
that air functioned as an insulator and that the heat did not damage normal surrounding lung parenchyma to any great extent,
because lung is filled with air. An experimental VX2 tumor in rabbits was well controlled by RF ablation. Since the clinical
use of RF ablation for lung malignancies was first reported in 2000, many series have been published. The patients reported
in these studies were not candidates for surgical treatment, either because of poor cardiopulmonary function and comorbidities,
or because they refused surgery. With RF ablation, complete necrosis can be expected for tumors with a diameter of 3 cm or
less. Palliative RF ablation may be indicated for large tumors. The most frequent complication associated with puncture was
pneumothorax, with a frequency higher for RF ablation compared with that for needle biopsy. The initial results have been
promising, but we await future reports for long-term results. 相似文献

Radiofrequency ablation has been applied as a minimally invasive therapy for the local control of lung tumors, including primary and metastatic neoplasms. Hemorrhagic complications after radiofrequency ablation can usually be treated conservatively, but such complications can be massive and fatal in some cases. In this paper, we report the rare case of delayed massive hemothorax caused by the rupture of a pulmonary artery pseudoaneurysm after lung radiofrequency ablation that was treated using transcatheter coil embolization followed by a left lower lobectomy. A 75-year-old woman underwent radiofrequency ablation for the treatment of a metastatic lung tumor in the left lower lobe arising from a colorectal carcinoma located close to a branch of the pulmonary artery. Thirty-six hours later, hemothorax and hemorrhagic shock occurred as a result of a ruptured pulmonary artery pseudoaneurysm and radiofrequency ablation-induced damage to the interlobular pleura. After transcatheter coil embolization of the pulmonary artery pseudoaneurysm, she recovered from a state of shock and a left lower lobectomy was performed. Histological findings revealed the presence of residual tumor cells in the ablated lung tumor. The postoperative course was uneventful, and no evidence of recurrence of the primary disease was seen at 1 year after the surgery. Although hemothorax secondary to the rupture of a pulmonary artery pseudoaneurysm after lung radiofrequency ablation is a rare complication, it should be recognized as a serious potential complication of lung radiofrequency ablation for a tumor located close to the pulmonary artery branch. 相似文献

Three cases are reported of invasive pulmonary aspergillosis (IPA) occurring after microwave ablation (MWA) for lung tumours. This is a rare complication that has not previously been described in the literature. The diagnosis of IPA was based on the following factors: host factors, clinical manifestations and mycological findings. The first case was a 63-year-old man treated for primary lung squamous carcinoma. Significant tumour regression was achieved by 18 days after MWA, medical treatment with itraconazole for 6 weeks, and postural drainage. The second case, a 65-year-old man, was confirmed with primary lung squamous cell carcinoma. Voriconazole administration using intravenous infusion combined with intracavitary lavage was therapeutically effective after MWA at 1 year follow-up. The third case was a 61-year-old woman with primary lung adenocarcinoma. Delayed pneumothorax and bronchopleural fistula secondary to IPA persisted. The patient died from secondary multiple organ function failure. Despite its very low incidence, the significance of early diagnosis and early administration of antifungal therapy should be highlighted because of the relentless severity of IPA in patients undergoing MWA. 相似文献
