Yucatan Pig: An Optimal Hairless Model for a True Random Cutaneous Flap

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.     

Free vascularized jejunum interposition for pharyngoesophageal reconstruction after total laryngopharyngectomy

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.     

四肢带表浅静脉干的局部皮瓣在创伤修复中的应用

设计4种带表浅静脉干的局部皮瓣用于修复四肢创面14例,获得了满意的效果。该皮瓣所包含的一条浅静脉干,不仅有利于静脉回流,且其血流对皮瓣亦有营养作用。因此,该皮瓣容易成活,长宽比值可大于传统任意型皮瓣。并具有操作简便,不损伤主要动脉等优点。文中介绍了皮瓣的设计及手术方法,并对该皮瓣的血液循环特点、适应证及供区选择等进行了讨论。     

去白细胞输血预防非溶血性发热性输血反应的临床应用

目的：评价临床输注法去白细胞红细胞悬液和浓缩血小板预防非溶血性发热性输血反应（FNHTR）的效果。方法：选择100例肝硬化、胃溃疡和胃癌等病人输注去白细胞红细胞悬液，对照组相类似50例病人输注普通红细胞悬液。240例急慢性白血病、再生障碍性贫血、多发性骨髓瘤、血小板减少性紫癜、糖尿病、肝硬化、上消化道出血、重症肝炎、烧伤、癌症放、化疗等患者分为两组，各组120例随机接受去白细胞血小板或未去白细胞血小板悬液。观察这些患者FNHTR的发生率。结果：在100例接受去白细胞红细胞悬液的患者中未发生FNHTR，对照组50例患者中有8例发生FNHTR，发生率为16%；血小板输注的患者中，去白细胞和未去白细胞的FNHTR发生7例和25例，发生率分别为5.83%和20.83%。结论：去白细胞输血可防止或减低FNHTR的发生。     

Rupture of an isolated internal iliac artery aneurysm into the rectum: Report of a case

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.

保留胸背神经的背阔肌皮瓣游离移植

目的 为减少背阔肌皮瓣切取时供区的代价，尽可能保留肌皮瓣切取后背阔肌的功能。方法 通过了解胸背神经、血管的解剖特点，切取肌皮瓣时不将胸背神经完全切断，保留部分或全部神经的支配。手术前后对背阔肌的神经肌肉动作电位进行检查，了解术后保留的背阔肌功能。临床应用20例修复下肢或前臂软组织缺损或伴骨外露。结果 19例移植皮瓣成活良好，保留的背阔肌有收缩功能存在。结论 在切取一定大小的背阔肌皮瓣时，保留胸背神经的支配，可减小背阔肌的功能损失，使供区的代价降低，符合皮瓣切取原则。
