A 4-year-old, male castrated European shorthair cat was presented with a firm mass palpable on the right caudal rib cage. Lateral and ventrodorsal radiographs of the thorax revealed a 4x3x2cm large, expansile and radiodense mass originating from the distal part of the 13th rib. After removal of the tumour, which was histopathologically confirmed as feline osteochondromatosis, the diaphragm, omentum, external abdominal oblique and latissimus dorsi muscles were used to reconstruct the defect. Feline osteochondromatosis is induced by retroviruses, eg, feline leukaemia virus, for which the cat tested positive. The tumour was removed for palliative reasons, because such tumours have the tendency to transform into osteosarcomas. Six months after the surgical excision the cat showed no clinical signs of reoccurrence. 相似文献

An 8-year-old, intact male miniature dachshund dog, weighing 8.6 kg, was presented with a soft swelling in the caudal abdominal region, including both sides of the groin area. Laparotomy revealed a severe caudal abdominal wall hernia with atrophy of the rectus abdominal muscle. The defect was repaired using a tunica vaginalis communis flap following a standard open prescrotal castration. There were no complications or recurrence of the hernia at 11 months after surgery. This surgical technique involves autogenous reconstruction, is easy to perform, and requires minimal dissection. The tunica vaginalis communis flap has potential clinical applications for repairing caudal abdominal wall hernias in male dogs. 相似文献

Loss of the caudal maxilla and ventral orbit after tumor resections can have negative functional and esthetic influences on the eye involved. This article reports on a case of a caudal maxillary acanthomatous ameloblastoma involving the ventral orbit that was resected and stabilized with a masseter muscle flap. The masseter muscle flap was generated from the superficial belly of the masseter muscle in order to close a defect in the orbital rim, created by a caudal maxillectomy. None of the published complications such as enophthalmos, excessive lacrimation, globe deviation, or strabismus were noted, 8 months following the procedure. The only clinical sign present at the time of re‐evaluation was mild lacrimation. The authors propose the use of a masseter muscle flap as a viable technique in stabilizing the ventral orbit after caudal maxillectomy and ventral orbitectomy, preventing the complications associated with this surgery. 相似文献

Hypertrophic scars found on the human body rarely develop in experimental animals, possibly due to their looser skin structure. This makes it difficult to understand the genesis of scar lesions. Therefore, appropriate animal models are urgently needed. In this study, we established a novel experimental model of a scar-forming wound by resecting a small portion of the abdominal muscle wall on the lower center of the abdomen in C57BL/6N mice, which are exposed to contractive forces by the surrounding muscle tissue. As a low-tension control, a back skin excision model was used with a splint fixed onto the excised skin edge, and granulation tissue formed on the muscle fascia supported by the back skeleton. One week after the resection, initial healing reactions, such as fibroblast proliferation, occurred in both models. However, after 21 days, lesions with collagen-rich granulation tissues, which were also accompanied by multiple nodular/spherical-like structures, developed only in the abdominal wall model. These lesions were analogous to scar lesions in humans. Therefore, the animal model developed in this study is unique in that fibrous scar tissues form under physiological conditions without using any artificial factors and is valuable for studying the pathogenesis and preclinical treatment of scar lesions. 相似文献

The case of a 2‐year‐old gelding with acute onset of preputial swelling and prolapse is presented. After initiating conservative management using a penile repulsion device, the horse repeatedly displayed signs of mild abdominal discomfort with sudden deterioration to an episode of violent colic after 5 days of hospitalisation. Ultrasonographic examination of the preputial swelling at that time demonstrated the presence of small intestine between the internal and external laminae of the prepuce and led to the diagnosis of a direct preputial hernia. The contents of the hernia were readily reduced through a defect in the ventral abdominal wall after the anaesthetised horse was placed in dorsal recumbency. The historical information, clinical progression and surgical findings were supportive of an acquired ventral abdominal wall defect. To the authors' knowledge, this is the first reported case of a direct preputial hernia associated with an acquired ventral abdominal wall defect. 相似文献

Internal obturator and/or semitendinosus muscle flaps were used to reinforce primary appositional rectal wall repair in three dogs and one cat in this case series. All three dogs incurred rectal wall compromise during surgical excision of anal sac tumours. The cat sustained bite wounds to the perianal region resulting in abscessation and a rectal tear. Our results indicate that application of an internal obturator and/or semitendinosus muscle flap can reduce the risk of rectal wall dehiscence after primary repair, and consequently the risk of pararectal abscess or rectocutaneous fistula formation. 相似文献

Applications of a semitendinosus muscle flap in two dogs 总被引:1,自引:0,他引:1
The proximal half of the semitendinosus muscle can be used as a versatile vascularized local transposition flap to reconstruct anatomic faults in the adjacent perineum in dogs. The flap is easy to dissect, and the arc of rotation is considerably beyond the midline. The location, size, and direction of the major vascular pedicle from the caudal gluteal artery is conducive to dependable flap perfusion. 相似文献

常规的苏木精和曙红组织化学染色是用于检测一般的肌细胞核表达方法,而用于确定肌纤维型表达的还有两种普遍公认的方法,即肌动球蛋白ATP酶酸、碱组织化学染色法。对骨骼肌异常肥大和肌萎缩症区分的一个重要因素是观察肌细胞核的形态变化。一种适宜的技术方法就是同时检查肌纤维型与肌细胞核两者比值,能应用于肌肉生长发育,肌萎缩症或某种程度的肌营养不良病。一般肌细胞核形态的检查和肌纤维构成的确定,通常需要使用以上描述的方法制作一系列肌纤维切片并做切片染色。我们目前设计的新方法用于联合检查冰冻肌组织切片内的肌纤维型与肌细胞核的同步显示,不失为是一种简便易行的好方法。 相似文献

Stoma site metastasis of gastric adenocarcinoma was documented 37 d after partial gastrectomy with gastrostomy tube placement, and 22 d after tube removal. The tube was placed through grossly normal tissue but histopathologic examination revealed neoplasia at the surgical margins and concurrent lymphatic metastasis. Stoma site metastases may be due to direct tumor seeding or hemolymphatic spread. 相似文献

A 16‐hour‐old Quarter Horse filly presented for evaluation of a soft mass in the right caudoventral lateral abdominal wall. Radiography and ultrasonography confirmed the presence of a nonreducible lateral abdominal wall hernia with small intestine located between the skin and body wall. The size of the defect itself could not be imaged and the filly was taken to surgery. A 4 cm vertical defect that appeared congenital was found in the transverse abdominal muscle and was repaired by primary apposition. This case report describes the repair and outcome of this unusual type of congenital hernia. 相似文献

This study evaluated the inflammatory mediator activin A in horses with acute abdominal disease and compared this putative novel biomarker with serum amyloid A (SAA). Thirty-three adult horses referred for evaluation of acute abdominal disease were grouped into three lesion categories, non-strangulating, strangulating or inflammatory. Eleven healthy adult horses served as controls. Serum activin-A was significantly increased in animals with inflammatory or strangulating lesions compared with controls. Horses with non-strangulating, strangulating or inflammatory lesions had significantly elevated SAA concentrations. Activin A, along with other biomarkers, may be useful in monitoring inflammation in cases of acute abdominal disease in horses. Further validation is warranted to determine the utility of this biomarker in evaluating the effectiveness of novel anti-inflammatory treatments for equine colic and endotoxaemia. 相似文献

A 5-year-old sexually intact female Yorkshire Terrier was referred with a history of fecal incontinence of at least 2 years and chronic intermittent colitis. The external anal sphincter to the left of the anus was intact; the external anal sphincter was not detectable to the right of the anus. To repair the defect, the semitendinosus muscle was isolated and severed 2 cm proximal to its insertion on the tibia. Care was taken to preserve the integrity of the vasculature and nerve supply in the proximal third of the muscle body. The body of the muscle was passed around the ventral and right aspects of the rectum; the cut end was secured with simple interrupted sutures dorsal to the levator ani and coccygeus muscles to simulate the external anal sphincter. After surgery, the dog could defecate normally. Absence of a portion of the external anal sphincter may be congenital or the result of anorectal trauma, rectal prolapse, severe perineal disease, or surgical resection. The use of a semitendinosus muscle flap for treatment of fecal incontinence secondary to sphincter incompetence in dogs may be a viable alternative to euthanasia. 相似文献

Abstract Extract Roberts (1956) refers to this condition as rupture of the prepubic tendon. While the condition he describes is nearly identical with that reported here, there was, in the present case, rupture of individual muscle layers cranial to the prepubic tendon. Another inconsistency is that this was a relatively light hack whereas Roberts describes the condition as occurring most commonly in heavier draught mares. 相似文献

A 9 yr old spayed female cocker spaniel presented for evaluation of an invasive maxillary squamous cell carcinoma. Curative intent surgery and radiation therapy allowed for local control of the neoplasm; however, the development of a persistent oronasal fistula prevented a complete recovery. A temporalis myofascial rotation flap allowed for successful resolution of the maxillary defect. Implementation of the flap was relatively simple and was associated with few complications. 相似文献
