Tubal obstruction is one of the most important causes of female infertility. Studies at home and abroad have shown that proximal tubal recanalization can be achieved by non-surgical means in at least 80% of patients. Tubal recanalization has been performed in the field of interventional treatment for more than 10 years. It has been adopted by clinicians and accepted by patients for its remarkable effectiveness and low complications in the diagnosis and treatment of tubal obstruction infertility. Selective tubal angiography and tubal recanalization have become one of the main methods for the treatment of tubal obstructive infertility.
