百例牛剖腹产手术的经验及技术探讨

难产是牛常见的产科病之一，奶牛发病明显高于黄牛。难产发生以后，经过各种办法难以从阴道产出犊牛，就应果断的，不失时机的施行剖腹产手术，从而有效的救治牛只。如能慎重果断的选择病例，早期进行手术，加上熟练的技术，成功率是很高的。     

Surgical treatment of phimosis due to preputial stenosis in a Thoroughbred colt

A 6-month-old Thoroughbred colt was referred to Rossdales Equine Hospital with a recent history of discomfort and inability to protrude the penis whilst urinating, resulting in accumulation of urine within the prepuce. Careful examination and manual palpation revealed a constrictive ring of fibrous tissue at the level of the preputial orifice. With no evidence of trauma or a persistent penile frenulum, a tentative diagnosis of phimosis due to congenital preputial stenosis was made. Exploratory surgery confirmed the diagnosis and surgical transection and release of the fibromuscular ring at three sites allowed the colt to protrude the penis and urinate normally immediately post-operatively. At follow-up examination 11 months later, the colt continued to be able to extrude the penis and urinate conventionally. A slight excess of skin was present at the end of the prepuce but this was only of minor cosmetic concern.     

Postenucleation orbital sialocele in a dog associated with prior parotid duct transposition

An orbital sialocele developed in a dog following enucleation for protracted glaucoma. This eye had historically been treated for keratoconjunctivitis sicca by parotid duct transposition approximately 5 years previously, and the duct was ligated distally at the time of enucleation. One month following enucleation, the dog presented with a fluctuant conical-shaped swelling ventrolateral to the orbital socket. Surgical exploration revealed a dilated, fibrotic distal portion of the previously transposed parotid duct, and saliva, within the enucleated orbit. The distal portion of the duct and saliva-containing tissues from within the orbit were excised. The remaining proximal normal portion of the parotid duct was re-routed into the oral cavity. Clinicopathologic and histologic examination of the excised orbital contents and dilated portion of duct revealed a sterile sample of saliva and moderate chronic periductal fibrosis. At a 6-month re-evaluation there was no evidence of recurrence of the sialocele, and the parotid duct was functional.

心脏原发肿瘤34例的诊断与外科治疗

目的：评价心脏原发肿瘤二维彩色超声心动图诊断的价值和外科治疗效果。方法：34例均用二维彩色超声心动图进行诊断，全组病例在低温体外循环下手术切除肿瘤(1例同期行股动脉切开取瘤栓术)。结果：术前32例发现心脏病理性杂音，24例有异常心电图表现，但心电图正常有10例。34例二维彩色超声心动图检查均发现有心脏原发肿瘤特征性表现，与手术所见完全相符，符合率达100．O％。34例中有32例术后痊愈出院并随诊未见复发。2例术后因低排综合征死亡。结论：二维彩色超声心动图是确诊心脏原发肿瘤最有效方法，一旦确诊应尽早手术治疗，手术疗效优良。     

SMAS平面下面颈皮瓣修复颊部皮肤缺损

目的报道SMAS平面下面颈皮瓣修复颊部皮肤软组织缺损的修复方法和疗效。方法于创面邻近部位设计前蒂或后蒂面颈皮瓣,于SMAS平面下掀起皮瓣后向内侧旋转推进覆盖颊区皮肤软组织缺损共20例。结果20例皮瓣均全部成活,其中1例术后腮腺瘘形成。术后随访2~13月,皮瓣外观满意,皮肤浅感觉良好,除1例术后半年内下睑外翻外余无面部器官移位及面神经损伤表现。结论SMAS下面颈皮瓣血供可靠,色泽、质地优良,与颊部匹配,是修复颊部皮肤软组织缺损的理想组织瓣。     

T-shaped malformation of the ventral colon in a Thoroughbred filly with colic

A 4-month-old Thoroughbred filly presented for abdominal pain was diagnosed with a T-shaped malformation of the ventral colon at exploratory laparotomy. Following resection and anastomosis of the large colon, no further episodes of abdominal pain occurred during a 12-month follow-up. Acute dehiscence of the linea alba occurred as a complication of the initial laparotomy, but was successfully managed following additional surgical repair. T-shaped malformation of the ventral colon has not previously been reported and is considered a congenital malformation of mesocolon formation.     

"C"形邻指皮瓣设计的改良和应用

目的：对“C”形邻指皮瓣的设计进行改良并观察12例的应用效果。方法：于皮瓣蒂部设计一矩形瓣用以制成皮管包裹血管蒂，增加皮瓣蒂的长度和旋转弧方便转移，同时使修复指端脱套伤时皮瓣仍可顺行设计从而携带指固有神经手背支。结果：临床应用12例。12例皮瓣全部成活。术后9例得到2～23个月的随访，皮瓣外观满意，感觉恢复良好。结论：改良“C”形邻指皮瓣既保留了“C”形邻指皮瓣的优点，又克服了其血管蒂短不便转移及修复指端创面时只能取逆行设计的缺点，是手指创面修复的理想方法。
