To report the results of long-term (>5 years) computed tomography (CT) angiography follow-up after thoracic endovascular aortic repair in patients with traumatic thoracic aortic injury.
All follow-up CT angiographies performed in patients with traumatic thoracic aorta injury treated by endovascular stent-graft between 2002 and 2008 were reviewed. Of the 14 patients treated, seven patients had CT angiography follow-up examinations for more than 5 years. All patients were men with a mean age of 26 years. The Talent device was used in four patients and Gore TAG device in three patients. The mean device diameter and length were 24.6 mm and 103 mm, respectively. Follow-up included annual outpatient clinic surveillance and CT angiography examinations, which were reviewed for any device-related complications. The radiation effective dose was calculated from the CT dose report.
Thirty-three CT examinations performed 64-110 months (mean 76) after stent-graft implementation were reviewed. The mean follow-up number of examinations per patient was 4.7 (range 2-8). Intra-graft circular mural tissue at the distal part of the stent-graft was seen in one patient. Stable lack of proximal device apposition was seen in all patients. No other radiological complications (e.g., aortic infection, dilatation, aneurysm or pseudoaneurysm, device struts breakage, migration, collapse, endoleak) were detected. None of the patients developed hypertension. The average effective dose was 77.01 mSv (range 34.11-128.84 mSv).
CT angiography did not reveal any complications developing throughout the long-term follow-up. These results suggest that long-term CT angiography follow-up may not be required.
报告胸主动脉创伤性损伤患者经血管内支架植入治疗后，长期（>5 年）计算机断层扫描（CT）血管造影随访结果。
回顾 2002 年至 2008 年间接受血管内支架植入治疗的胸主动脉创伤性损伤患者的所有随访 CT 血管造影检查。14 例患者中，7 例患者的 CT 血管造影随访时间超过 5 年。所有患者均为男性，平均年龄为 26 岁。4 例患者使用 Talent 装置，3 例患者使用 Gore TAG 装置。装置平均直径和长度分别为 24.6mm 和 103mm。随访包括每年门诊监测和 CT 血管造影检查，以评估任何与器械相关的并发症。辐射有效剂量由 CT 剂量报告计算得出。
回顾了支架植入后 64-110 个月（平均 76 个月）的 33 次 CT 检查。每位患者的平均随访检查次数为 4.7 次（范围 2-8 次）。在 1 例患者的支架远端可见腔内环状壁组织。所有患者近端装置均稳定无贴附。未发现其他影像学并发症（如主动脉感染、扩张、动脉瘤或假性动脉瘤、器械支架断裂、移位、塌陷、内漏）。患者均未发生高血压。平均有效剂量为 77.01mSv（范围 34.11-128.84mSv）。
长期 CT 血管造影随访未发现任何并发症。这些结果表明，可能不需要进行长期 CT 血管造影随访。
