Complications of varicose vein surgeries are frequently asked to the vascular surgeon. Often this is not discussed in depth it should. Even because in most cases of varicose veins the patient has the option of doing nothing. The following table has the complication rates of various procedures that can be done for varicose veins.
As a scientific basis for the charts we took the complications in a systematic review of Cochrane, which translates clinical trials on the subject. References at the bottom of the page if there is interest. Two observations before analyzing.
Note 1: Studies on skin blemishes have had different methods and different assessment between techniques. In the CHIVA x stripping studies, CHIVA had hematomas at 46% and stripping at 71%. In the Laser x stripping studies the laser had spots in 31% and surgery in 39%. This suggests that CHIVA studies were stricter or earlier in this evaluation than laser studies. Concrnig skin spots on foam, the meta-analysis revealed that in Stripping 3.2% and in the foam 4.5% of the patients had spots. The same Stripping surgery that had 71% in the studies against CHIVA had 3.2% in the studies against foam, making it clear that the method of evaluation was different. There are studies that demonstrate early skin blemishes with 30% foam. This probably happened because some studies evaluated patients soon after and others evaluated months later when many of the spots were gone.
Note 2- On recurrence CHIVA and Stripping have data up to 10 years, laser up to 5 and foam up to 2 years.
