经皮肤穿刺治疗“汗手症”

经皮肤穿刺治疗“汗手症”
 
一种由CT透视辅助的微创方案，能够永久治疗手掌多汗症，通常被叫做“汗手”。这种疾病是由于交感神经系统活性过高而引起的。

CT透视辅助的经皮肤交感神经阻断术是一项只需要20分钟的手术，无需麻醉，没有神经损伤或者出血的危险，只有出现Horner综合征的微小风险，该综合征会影响眼睑的运动。

在此之前唯一的能够永久治疗汗手的方法，是胸部传统或者内窥镜下手术交感神经阻断术，而那需要全身或者局部麻醉。

在该治疗方案中，医生只需要通过上背部一次针刺穿刺，使用CT引导，注射一种含酚的药物，破坏传递信号到出汗神经结的神经束和神经结。许多患者需要在两侧各做一次治疗。手术交感神经阻断术，可能会出现无法预测但是十分罕见的在胸部水平代偿性出汗的危险。

Percutaneous Solution for Sweaty Hands
 
A minimally invasive procedure that is assisted by CT fluoroscopy can permanently cure people who suffer from palmar hyperhidrosis, commonly known as “sweaty hands.” The condition is caused by an overactivity of the sympathetic nervous system.

Percutaneous sympathectomy with computed tomography (CT) fluoroscopy is a 20-minute procedure requiring no anesthesia, with no risk of nerve damage or bleeding and only minimal risk of Horner syndrome, which affects movement of the eyelid.

Previously, the only known permanent treatments for sweaty hands were thoracic conventional or endoscopic surgical sympathectomies that required general or local anesthesia.

In the procedure, doctors make a single needle puncture through the upper back and, using CT guidance, inject a phenol-based medication that interrupts the nerve tracts and nodes that transmit signals to the sweat glands. Most patients require a single treatment for each side. As with surgical sympathectomy, there is an unpredictable but rare risk of compensatory sweating at the level of the chest.
