A new nasal tunnel in the correction of paralytic lagophthalmos with free muscle grafts

Summary A modified method is described for the construction of a tunnel through the nasal bones in order to accomodate the tendon in Thompson's muscle grafting technique for the treatment of paralytic lagophthalmos.We are grateful to Prof. Dr. A.J.C. Huffstadt, the Medical Photography department, Miss J. de Grijs, Mr. D. Buiter, and Miss R. Julsing for their help in preparing this paper.     

Restoration of patency after apparent occlusion of the λ-graft's right branch

The “string sign” is a physiological and reversible response of the internal mammary artery (IMA) anastomosed to a moderately stenotic coronary artery. We describe a patient who presented postoperatively with a string sign phenomenon of the right branch of the λ-composite graft. The graft regained full patency 32 months after the surgical procedure with progression of the native coronary artery stenotic lesion. This case demonstrates that under specific conditions, such as the progression of native coronary artery disease, a no-flow composite graft employing IMAs can only regain patency and functional status in the same way as in situ IMAs. These findings confirm that the IMA remains the conduit of choice not only for its long-term patency, but also for its physiological adaptation characteristics.

爆裂性眼眶骨折骨缺损修复的临床观察

目的探讨眼眶骨折骨缺损修复材料的性能。方法采用不同的修复材料:如自体骨、羟基磷灰石、医用硅胶等,分别填充于眶壁骨折缺损处,比较三种物质术后反应情况。结果自体骨术后反应轻,组织相容性好,愈合快,无排异,愈合后无硬节。结论自体骨是眶壁骨折骨缺损修复的最佳材料。     

Stanford B型胸主动脉夹层动脉瘤合并肾缺血的诊治(附3例报告)

为探讨合并肾缺血的StanfordB型胸主动脉夹层动脉瘤的诊断和处理 ,分析 1996年 1月至 2 0 0 0年 4月收治的StanfordB型胸主动脉夹层动脉瘤 2 9例 ,其中合并肾缺血 3例 ,为急性期 2例 ,慢性期 1例。急性期 1例发病后第 3天死亡 ,另 1例同时合并肾缺血和双下肢缺血 ,经夹层隔膜开窗术缓解 ;慢性期 1例经腔内隔绝术治愈夹层后肾缺血自行缓解。提示合并肾缺血的StanfordB型胸主动脉夹层动脉姑息性转流手术有助于缓解症状 ,提高生存率 ;对于慢性StanfordB型胸主动脉夹层动脉瘤合并肾缺血的患者 ,腔内隔绝术在治愈夹层动脉瘤的同时恢复了真腔供血 ,肾缺血可同时治愈     

腹主动脉瘤腔内隔绝术后内漏的治疗

为探讨腹主动脉瘤（AAA）腔内隔绝术（EVGE）后内漏产生的原因和治疗方法,作者总结分析了38例腔内隔绝术并发内漏的诊治体会。38例腔内隔绝术中共4例并发内漏,其中I型内漏2例,Ⅱ型内漏1例,Ⅲ型内漏1例;1例中转传统手术,其余3例在观察中。DSA是术中发现内漏的有效手段,球囊扩张法、支架法、移植物法和栓堵法是治疗内漏的有效方法。     

胸主动脉夹层动脉瘤腔内隔绝术后内漏的评估

32例StanfordB型胸主动脉夹层动脉瘤患者接受了腔内隔绝术,术中发现内漏4例,即时腔内方式治愈3例,自愈1例;术后迟发型内漏1例。内漏的发生与多种因素有关,术中DSA及术后螺旋CT是发现内漏的有效方法;发生内漏后主张尽快以腔内方式治疗;小量内漏可自愈;迟发型内漏的治疗及转归有待继续讨论。     

Time-resolved MR angiography for the classification of endoleaks after endovascular aneurysm repair

PURPOSE: To evaluate the utility of time-resolved MR angiography (TR-MRA), compared with digital subtraction angiography (DSA), in the classification of endoleaks in patients who have undergone endovascular aneurysm repair (EVAR). MATERIALS AND METHODS: Thirty-one patients who had undergone EVAR to repair an abdominal aortic aneurysm were evaluated with both TR-MRA and DSA to determine endoleak etiology. The patient population consisted of 26 men and 5 women with a mean age of 78.5 years (range, 55-93 years). The mean time interval between TR-MRA and DSA was 1.5 weeks (range, 1-8 weeks). Endoleaks were classified as type II when enhancement of the external iliac vessels was observed before the appearance of the endoleak; otherwise the endoleak was classified as type I or III. The results of TR-MRA classification were compared with the reference gold standard, DSA. RESULTS: Agreement between TR-MRA and DSA regarding endoleak classification occurred in 30 of 31 cases (97%). Discordant classification occurred in a case in which a Type II endoleak was misclassified as a Type III due to failure to visualize a lumbar vessel. CONCLUSION: TR-MRA is highly effective in classifying endoleaks following EVAR when compared with DSA.     

手术联合腔内技术治疗下肢深静脉血栓形成

目的: 总结手术联合腔内技术治疗下肢深静脉血栓形成(deep venous thrombosis,DVT)的初步经验。方法: 对48例下肢DVT患者采取腔静脉滤器植入、股静脉切开取栓、髂静脉球囊扩张内置支架以及暂时性动静脉瘘等方法治疗。结果: 随访1-38个月,26例肢体肿胀消退,无浅表静脉怒张,11例肢体轻微肿胀伴浅表静脉扩张,3例肢体肿胀稍消退,症状有所减轻,1例支架内血栓形成。无肺栓塞发生,无滤器内血栓残留。1例术后1个月对侧肢体发生DVT。结论: 本法创伤小,操作简单,安全、有效,是治疗下肢DVT较好的选择,但远期疗效有待进一步研究。     

肾下型腹主动脉瘤的外科治疗

目的: 总结肾下型腹主动脉瘤(abdominal aortic aneurysms,AAA)外科治疗经验。方法: 对25例肾下型腹主动脉瘤分别行传统外科手术19例,腔内修复术4例,非手术治疗2例。结果: 23例施行手术,死亡2例,均为AAA破裂急诊手术者,其中1例术后死于多器官功能障碍综合征,1例术后死于呼吸道感染、急性呼吸窘迫综合征。另2例AAA破裂患者因病情危重未治病死。围手术期死亡率为8.7%,其中择期手术为0,急诊手术为50%。随访18例,随访时间3个月至6年,无动脉瘤复发,无吻合口假性动脉瘤,无吻合口破裂出血,手术后人工血管通畅。腔内修复术患者支架无移位,通畅,无肠缺血、无内漏发生。结论: 手术切除腹主动脉瘤疗效是满意、安全的。腔内治疗特别适用于高危患者。
