A Clampless Technique to Facilitate Successful End-to-End Anastomosis in Small Vessels With Spasm.

摘要: ABSTRACT End-to-end anastomosis in small arteries can be challenging, especially when the stumps are spasm after traumatic transection. We describe a novel technique to facilitate such anastomoses under local anesthesia, presenting 24-year old patient who suffered complete transection of left ulnar artery. After having found and prepared proximal distal stumps, soft polyurethane feeding tube (La-med Healthcare, India) vein cannula were inserted stump, respectively, without using vascular clamps. The manipulation catheters offered excellent visualization widening anastomotic line, enabling simultaneous infusion heparinized saline or vasodilating agents. was completed with no stenosis pulpable pulses restored immediately postoperatively. At 1-month follow up Allen test normal regular flow artery at duplex ultrasound. described ensures efficient sealing avoiding clamping, casts lumens, provides optimal aspects prevents stenosis. believe it should have place surgeon's armamentarium.
