Hard lumps that remain after minimally invasive varicose vein surgery are commonly due to infection, local hematoma formation, and scarring of the tissues after surgery.
Minimally invasive varicose vein surgery is also an invasive procedure that can cause tissue damage, and scarring can occur during the process of repairing the tissue damage, so localized scarring of the tissue after surgery is not a sign of unsuccessful surgery. Scarring can also occur after surgery due to infection or local hematoma formation and tissue mechanization.
Scarring after minimally invasive varicose vein surgery can be accelerated by some measures, such as the use of hot water towels to apply hot compresses, the operation should be careful to avoid scalding, and it needs to be after the wound has completely healed. In addition, if the scar proliferation is more obvious, you need to go to the hospital in time to rule out other diseases.
