CHIVA () is a surgical technique for varicose veins that avoids destroying the saphenous vein and collaterals. In some patients, the flush ligation of saphenous collaterals performed in the CHIVA technique may require more dissection than is desirable. This is especially valid for obese patients and thigh ligations. We report an innovative technique that uses duplex-guided puncture to bring the collateral closer to the skin and reduce the need for dissection and incision. The technique does not change any of the CHIVA principles. While the long-term results are not yet known, we expect them to be similar to normal CHIVA procedures.
CHIVA（）是一种用于治疗静脉曲张的外科技术，可避免破坏大隐静脉及其分支。在一些患者中，CHIVA技术中对大隐静脉分支进行的平流式结扎可能需要比预期更多的解剖操作。这在肥胖患者和大腿结扎中尤为明显。我们报告了一种创新技术，该技术使用双功超声引导穿刺使分支更靠近皮肤，减少解剖和切口的需求。该技术并未改变任何CHIVA原则。虽然长期结果尚不清楚，但我们预计它们与正常的CHIVA手术相似。
