Microneedling for thrombus removal, this could be true. For patients with superficial thrombophlebitis, the thrombus is on the surface, and the patient will feel swelling of the skin, high skin temperature, tenderness, and be able to palpate hard strips. If it is a newly formed thrombus in the superficial vein, a fine needle can be used to puncture directly into the inner part of the thrombus, and then squeeze out the thrombus, which can reduce the patient’s redness, swelling, heat, and pain caused by the thrombus. But relatively speaking, the choice should be thicker, because the diameter is larger, the thrombus is easier to come out. It is also very difficult to take out completely, so it can take out part of it, and then absorb part of it in the body, and accelerate the absorption of the thrombus through medication.
