目的 探讨闭孔疝的诊断和治疗方法。方法 回顾性分析了我院2001年10月至2009年8月期间收治并经手术证实的8例闭孔疝患者的临床资料。结果 8例均为女性，其中7例是老年、体弱的多产妇，1例是已婚年轻女性。平均年龄74.6岁（46～85岁），平均体重为39.1 kg（34～43 kg），平均生育5胎（1～10胎）。8例患者中5例术前经CT检查确诊而行手术治疗，3例由外院转入者在行急诊剖腹探查术中确诊。7例行坏死小肠切除吻合术，1例行嵌頓小肠复位术。 术后4例出现并发症：1例肺炎、1例切口感染、1例低蛋白水肿、1例为酸中毒和低血钾（死亡）。7例痊愈出院，1例死亡。结论 闭孔疝缺乏特异性表现，对年老体弱的经产妇出现腹痛、呕吐和股部疼痛应想到闭孔疝的可能；CT检查能提高闭孔疝的诊断率。准确的诊断和及时的手术干预是改善闭孔疝患者预后的关键。
This article interprets the core content of Chinese expert consensus on the CT examination for transcatheter aortic valve replacement and Chinese expert consensus on standardized evaluation of CT for transcatheter aortic valve replacement, and elaborates on the technical points of preoperative and postoperative CT examination for transcatheter aortic valve replacement (TAVR), including patient preparation, data acquisition, image reconstruction, and contrast agent use strategies. The article also provides an in-depth interpretation of the crucial elements in standardized CT evaluation for TAVR, covering assessments of aortic root anatomy, cardiac morphology, coronary arteries, and surgical access routes. The article emphasizes the significance of the above consensuses in standardizing TAVR-related CT examinations, improving diagnosis and treatment quality, and promoting the development of cardiovascular intervention therapy in China.
