I'd like to write my opinion about the following parts written on the Endoscopic thoracic sympathectomy page of Wikipedia.
Exact results of ETS are impossible to predict, because of considerable anatomic variation in nerve function from one patient to the next, and also because of variations in surgical technique. The autonomic nervous system is not anatomically exact and connections might exist which are unpredictably affected when the nerves are disabled. This problem was demonstrated by a significant number of patients who underwent sympathectomy at the same level for hand sweating, but who then presented a reduction or elimination of feet sweating, in contrast to others who were not affected in this way. No reliable operation exists for foot sweating except lumbar sympathectomy, at the opposite end of the sympathetic chain.
I have been explaining the feeling of myself using the phrase of "feeling of nerve flow" several times using diagrams. In some diaries on this blog, it is explained in the text. （"it flows toward the back of the right shoulder, and flows to the entire back, to the left shoulder, to the left palm, and to the left temple through the left side of the back of the neck." or "it is heading from the yellow area to the left shoulder along the back of the neck." and so on）
Of course, I still feel the feeling of nerve flow in such places, so I will add it in red in the figure.
When the right hand is numb, the left hand is usually numb at the same time. If the green part of the figure is blocked interruptedly so numb is set up beyond that, I think it's correct that numbness are occurred simultaneously in both hands.
And It also flows toward the back. If it can reach the foot beyond that, I think that it also makes sense for some people who took ETS surgery to stop sweating their feet at the same time.
If they worry about sweating on their hands, it means that their nerves are already hypersensitive, so the extended nerves that have reached their feet have also overreacted, resulting in hyperhidrosis of their feet. However, if the nerve of another path was sweating the feet, then it would not stop, but rather the sweat on the feet would be stronger...
I think this is an "individual difference".
Another thing I was interested in is the following description.
The most common area targeted in sympathectomy is the upper thoracic region, that part of the sympathetic chain lying between the first and fifth thoracic vertebrae.
I think it means three sympathetic ganglion between T2 - T4, so, for example, even if the procedure was to eliminate the T4 sympathetic ganglion, this article should be considered applicable. That is, though it may be told "If low-level elimination, it is safe.", though though it may be correct that it is less fatal side effects than T2 elimination, it's worth understanding that some side effects still occur as described in this article, and some people are unacceptable for their symptoms.Back to English articles
