阔筋膜皮瓣移植修复手前臂巨大创面 总被引:4,自引:0,他引:4
报道采用吻合血管的阔筋膜皮瓣移植,修复手、前臂巨大创面11例,均获成功,其优点:①阔筋膜长而坚韧,内面光滑,覆盖关节、骨、肌腱粘连轻,尤其利于肌腱滑动,是修复手、前臂的最佳皮瓣。②皮肤与肌腱同时缺损时,利用阔筋膜修复肌腰,一期完成肌腱及皮肤的修复。③股外侧皮神经长而粗,分支多,适合手部感觉修复。④供区隐蔽,皮下组织簿,血运丰富,供皮及阔筋膜面积大。 相似文献

Porcine models have been used extensively for skin flap research because of the established similarity between the cutaneous
blood supply of the swine and humans. The Yucatan minipig provides an excellent model for researching the properties of random
cutaneous flaps, offering several advantages over other breeds of swine. In this study, a total of 67 random cutaneous dorsal
flank flaps measuring 4 × 14 cm were raised on nine Yucatan minipigs. The mean survival length (10.03 ± 1.60 cm) of the nondelayed
flaps was greater than others reported in the literature. The well-defined plane between the subcutaneous tissue and the panniculus
carnosus facilitated flap elevation consistently above the level of the panniculus carnosus thereby ensuring the creation
of a true random cutaneous flap. Furthermore, the hairless nature of the skin, particularly beneficial in studying chemical
peels, permits easy visualization and monitoring of any external skin changes. These advantages make the Yucatan minipig a
more desirable alternative to other breeds of swine for use in skin flap research. 相似文献

目的:观察吸入一氧化氮(NO)对心瓣膜置换术后肺动脉高压患者血流动力学的影响。方法:选择9例心瓣膜置换术后伴肺动脉高压的病人,吸入NO0.003%,观察三个时象点:吸入NO前;开始吸入NO后15分钟;停止吸入NO后15分钟。结果:吸入NO能显著降低肺动脉压和肺循环阻力指数(P<0.01),停止吸入NO15分钟后,肺动脉压和肺循环阻力指数恢复到原有水平。在整个观察过程中,心率、平均动脉压、中心静脉压、肺动脉楔压、体循环阻力指数和心脏指数均无显著变化(P>0.05)。结论:吸入NO具有选择性肺血管扩张作用,是治疗心瓣膜置换术后肺动脉高压的较理想药物。 相似文献

Severe aortic regurgitation was discovered in a young man 21 days after blunt chest trauma and after a prolonged febrile state with positive blood cultures. Using transoesophageal echocardiography (TEE), it was possible to make the differential diagnosis between traumatic rupture and endocarditis as the cause of valvular insufficiency. The use of TEE in the initial evaluation of severe thoracic trauma with an unclear clinical picture is recommended. This method is easy to use at the bedside and gives precise information on the aortic valve and the ascending aorta. 相似文献

The records of 28 patients who underwent free jejunal graft reconstruction after resection for cancer involving the pharynx were analysed. Seven patients had a T3 carcinoma, 15 patients T4 and six patients recurrence after laryngectomy. Ten patients had received radiotherapy in the past. Post-operatively, 15 patients (54%) had complications and two patients (7%) died. No significant difference was observed in the complication rate between the group that received radiotherapy in the past and those who did not. Nineteen patients received post-operative radiotherapy. Nine patients had no radiotherapy on the basis of complete resection or because of serious complications. For the whole group the 2-year recurrence free period and survival were 42% and 51% respectively. The postoperative radiotherapy group had a significantly better survival (73%) and recurrence free period (63%) than the group without post-operative radiotherapy (0%). Thus, post-operative radiotherapy seems indicated irrespective of resection margins. 相似文献

Surgically uncorrectable tricuspid valve disease in children is rare. However, when it happens the surgical options are very limited. Tricuspid valve replacement using a mechanical valve or stented bioprosthesis is impractical. Use of homografts in the “anatomic position” has its limitations. We report here the use of an extracardiac homograft connection between the right atrium and right ventricle in a 16-month-old boy in whom severe tricuspid valve stenosis developed after surgical repair of a complex ventricular septal defect associated with dextrocardia and anomalous systemic venous drainage. The patient remains well receiving no cardiac medication 12 months after the procedure. 相似文献

目的采用新型高分子材料制备人工心脏瓣膜,并对其体外流体力学特征作出评价。方法将片状超微孔膨体聚四氟乙烯材料缝制于弹性支架上做成人工心脏瓣膜,以Baxter人工双叶机械瓣作对照,对新型瓣膜进行了静态泄漏和定常流测试。结果两种瓣膜静态泄漏率无显著差异(P>0.05),定常流下高分子瓣膜跨瓣压差更低,两组间存在显著差异(P<0.001)。结论新型高分子人工心脏瓣膜体外流体动力学性能优于Baxter机械瓣。 相似文献

Aneurysmal rupture into the intestinal tract is a rare but disastrous complication of an internal iliac artery aneurysm. We report herein the successful surgical repair of a fistula between a huge aneurysm of the right internal iliac artery and the rectum in an 81-year-old man. After a femoro-femoral cross-over bypass had been performed, the aneurysm was opened and its patent arterial branches were ligated with sutures. The fistula was then intra-aneurysmally sutured and covered with an omental flap. The diagnostic and therapeutic approaches to this severe complication are discussed with a review of the literature following the presentation of this case. 相似文献
