Force Cta And Post-Processing Techniques Play An Important Role In Preoperative Diagnosis Of Limb Arteriovenous Fistula

Arteriovenous fistula (AVF) refers to an abnormal pathway between the arteries and veins, and is seen in the extremities. This is a rare congenital left lower extremity arteriovenous fistula with multiple deformities. CTA examination and all kinds of post-processing and reconstruction techniques of CT clearly showed left lower extremity arteriovenous fistula and deformity, multiple hemangioma, and pseudoaneurysm at the left thigh root of a 28-year-old female patient. Under the guidance of DSA, the patient received the method of embolization of spring coil. However, the diffuse congenital arteriovenous fistula (CAVF) is easy to relapse and the patient should be followed up closely. Therefore, CTA and CT post-processing technology is of great value in preoperative diagnosis and postoperative evaluation of CAVF.
