This study was designed to evaluate a recently introduced form of stripping of primary varicose veins by the technique of perforate-invaginate (PIN) stripping.
One hundred twelve consecutive limbs presenting with 91 long and 21 short saphenous varicosities displaying saphenofemoral or saphenopopliteal junctional escapes with varying length of greater or lesser saphenous (axial) reflux underwent operation in 1 year. All surgeries were performed in an office setting with the patient receiving locoregional anesthetic with use of the invaginated PIN stripping in conjunction with tributary hook-stab avulsion.
In the 112 procedures performed, there were no tract hematomas or dysesthesias caused by nerve damage. Postoperative morbidity was nonexistent, permitting all patients to resume normal daily occupational and sporting activities immediately.
PIN stripping is an excellent method of invagination stripping. There is a minimal likelihood of vein tearing. Compared with conventional ankle-to-groin (or popliteal fossa) stripping, PIN stripping is minimally invasive, does not cause damage to structures around the vein, does not require convalescence, eliminates the need for a lengthy distal second incision, can be performed in an office setting with the patient receiving locoregional anesthetic, and is most cost-efficient.
本研究旨在评估一种最近引入的通过经穿支内翻（PIN）剥脱技术治疗原发性静脉曲张的方法。
在1年时间里，对112条连续的肢体进行了手术，这些肢体存在91条大隐静脉曲张和21条小隐静脉曲张，伴有大隐或小隐（轴性）反流的不同长度的隐股或隐腘交界点逃逸。所有手术均在门诊进行，患者接受局部麻醉，采用内翻PIN剥脱术联合分支钩刺撕脱术。
在进行的112例手术中，未出现因神经损伤导致的术道血肿或感觉异常。术后无并发症，所有患者均可立即恢复正常的日常工作和体育活动。
PIN剥脱术是一种出色的内翻剥脱方法。静脉撕裂的可能性极小。与传统的从脚踝到腹股沟（或腘窝）的剥脱术相比，PIN剥脱术微创，不会对静脉周围结构造成损伤，无需康复期，无需进行冗长的远端第二个切口，可在门诊进行，患者接受局部麻醉，且成本效益最高。
