Proliferative fistula type and contralateral feeders were associated with initial CNP in CSDAVFs, while coil packing location significantly influenced posttreatment aggravation. Complete CNP resolution was achieved in most patients, though factors such as hypertension, severe initial symptoms, and retreatment negatively affected recovery. These findings highlight key clinical and angiographic variables critical for guiding treatment strategies and predicting outcomes in patients with CSDAVF.
