Comparing the Safety and Efficacy of Cerebral TFA and TRA Methods

In transradial access, no preprocedural upper extremity collateral blood supply testing was completed. When the radial access is unsuccessful, it is shifted to ulnar or femoral access. All right arms were secured in the fully supine position to allow access to both radial and ulnar arteries. At the conclusion of radial access procedures, a TR band was applied to close the access. Neurological exams as well as radial artery pulse and pulse oximeter of the right first finger were assessed during and on discharge by trained recovery nurses. Femoral access was performed in a standard manner. After the access (femoral or radial), a cerebral angiogram was performed in a standard manner using appropriate catheters (vertebral, bern, Simmons 2 or 3) according to the access. For the radial access, the patient was slightly sedated.
