目的:描述乳房切除术的适应症和手术技术,并描述回顾性病例系列中10例乳房切除术的结果。
方法:10只患有一个或两个乳腺疾病的母马。
方法:检索了2所大学教学医院的医疗记录(1995年至2022年),以确定进行过单侧或双侧乳房切除术的母马。有关历史记录的数据,信号,诊断测试,术前治疗,外科手术,并对术后管理进行了回顾。通过电话采访业主获得了后续信息。
结果:切除了一个(n=4母马)或两个乳腺(6母马),原因如下:慢性细菌性乳腺炎(4),瘤形成(3),淋巴管扩张症(1),化脓症(1),和淋巴错构瘤(1)。没有一匹母马经历术中并发症。手术部位主要在2匹母马中闭合,在8匹母马中未缝合。两个缝合的伤口都出现了血清肿,和1嘘。业主报告说手术伤口,无论是缝合的还是未缝合的,在3个月内痊愈。所有的母马都回到了预定的用途,但3只母马在手术后2至4年因疾病进展而被安乐死。一只母马在出院一年后溺水身亡。
结论:当母马难以接受药物治疗时,乳房切除术可以有效地治疗患有一个或两个乳腺疾病的母马。
OBJECTIVE: To describe the indications for and surgical technique of mastectomy of mares and to describe the outcome of 10 mares that underwent mastectomy in a retrospective case series.
METHODS: 10 mares having disease of one or both mammary glands.
METHODS: Medical records (1995 to 2022) from 2 university teaching hospitals were searched to identify mares that had undergone unilateral or bilateral mastectomy. Data regarding history, signalment, diagnostic tests, preoperative treatment, surgical procedure, and postoperative management were reviewed. Follow-up information was obtained by interviewing the owners by telephone.
RESULTS: One (n = 4 mares) or both mammary glands (6 mares) were excised for the following reasons: chronic bacterial mastitis (4), neoplasia (3), lymphangiectasia (1), pythiosis (1), and lymphoid hamartoma (1). None of the mares experienced intraoperative complications. The surgical site was closed primarily in 2 mares and left unsutured in 8 mares. Both sutured wounds developed a seroma, and 1 dehisced. The owners reported that the surgical wound, whether sutured or unsutured, was healed within 3 months. All mares returned to use for their intended purpose, but 3 mares were euthanized 2 to 4 years after surgery due to progression of disease. One
mare drowned 1 year after discharge.
CONCLUSIONS: Mastectomy can be an effective treatment for mares suffering from disease of one or both mammary glands when the
mare is refractory to medical treatment.
