  • 第四腰动脉穿支皮瓣治疗骶尾部小面积褥疮

    目的总结第4腰动脉穿支皮瓣修复骶尾部小面积褥疮的疗效。 方法2002 年1月-2012年10月,采用第4腰动脉穿支皮瓣修复骶尾部小面积褥疮17例。男11例,女6例;年龄23~84岁,平均71.6岁。褥疮根据美国国家压疮专家组(NPUAP)分度标准:Ⅲ度8例,Ⅳ度9例。病程30 d~9个月,平均2.5个月。褥疮范围5 cm × 4 cm~7 cm × 5 cm。皮瓣切取范围15 cm × 8 cm~17 cm × 10 cm。供区直接缝合。 结果术后1例皮瓣边缘坏死、1例切口愈合不良合并轻度感染,均经对症治疗后愈合;其余皮瓣完全成活,创面Ⅰ期愈合。供区1例切口边缘皮肤坏死,经换药愈合;其余切口均Ⅰ期愈合。1例术后2个月余因股骨粗隆间骨折合并肺部感染死亡;余16例获随访,随访时间3 个月~2年,平均6.4个月。皮瓣质地优良,外形满意,皮肤颜色及弹性均恢复较好,术后3个月皮瓣触、痛觉与周围正常皮肤相似。褥疮无复发。 结论第4腰动脉穿支皮瓣设计简便、血供可靠、不损伤臀部肌肉、供区无需植皮,术后褥疮复发率低,是修复骶尾部小面积褥疮的有效方法之一。

  • Applied Anatomy Research of Lumbar Artery and Vein in Lumbar and Sacral Spinal Surgery

    目的:对腰动静脉的位置分布及变异进行描述和统计分析,以提高腰骶段脊柱手术手术的安全性和有效性.方法:对30具尸体标本进行解剖学研究,主要观察(1)腰动静脉的数量与缺失,各节段腰动静脉发出点位置的定性描述,(2)腰动静脉左右共干与上下共干的概率以及腰动静脉的其他变异。结果: 腰动脉的数量以及位置相对固定,有5对腰动脉的一共有5例,腰动脉发出点的位置也不是完全与腰椎对应。腰动脉左右共干的占9.6%,未见上下共干。动脉中仅有65.3%的动脉有静脉伴行。腰静脉的数量变异非常大,最少一侧仅有1支腰静脉,最多有5支,最常见的情况是3支,占36.7%。腰静脉的位置变异也较大,与椎体没有特别的规律。腰静脉的左右共干的概率要大于动脉,为38.5%,而上下共干也是腰静脉的独有的现象,总共有26支,占总数的12.5%。另外,腰静脉的其他变异多见。结论:当脊柱手术选择腹主动脉左侧入路或者腹主动脉下腔静脉之间入路时,腰动脉和腰静脉的解剖特点尤为重要。动脉的位置相对较恒定,而静脉则变异较大,缺失常见,左右共干,上下共干,静脉之间的大的交通支常见,与腰椎的对应性不如动脉,且其与动脉并非严格伴行,这些原因都造成了静脉容易损伤的原因,在手术中应该特别注意。

  • Risk Factors Analysis of Type Ⅱ Endoleak after Endovascular Aneurysm Repair

    ObjectiveTo discuss the risk factors of type Ⅱ endoleak after endovascular aneurysm repair(EVAR). MethodsThe clinical data of 197 cases of abdominal aortic aneurysm who underwent EVAR in our hospital from Jan. 2006 to Mar. 2011 were analyzed retrospectively, and risk factors of type Ⅱ endoleak were explored by logistic regression. ResultsOf the 197 cases, 18 cases suffered from type Ⅱ endoleak. Result of logistic regression showed that the risk of type Ⅱ endoleak increased per 1 of the increase of lumbar artery number(OR=1.822, P=0.010) and per 1 mm of the increase of lumbar artery diameter(OR=1.256, P=0.040). All of the cases were followed up for 1-36 months(median value of 16.8 months). Only 1 case was intervened by inferior mesenteric artery embolism for the growth rate larger than 5 mm during half a year, who was not found growth of diameter after the embolism. The type Ⅱ endoleaks of other 17 cases closed ultimately or keeping stable. ConclusionsType Ⅱ endoleak after EVAR is affected by the number and diameter of lumbar artery. Persistent type Ⅱ endoleak without enlargement of diameter of aneurysm sac needs to beclosely followed-up instead of re-intervention.
