Text: Using the cervical vacuum cap cannula, compared with the metal cannula, the duration of the procedure was significantly shorter (5. 3 vs 9. 3 minutes ; P < 0. 001), less fluoroscopic time was needed (0. 9 vs 1. 8 minutes ; P < 0. 001), a smaller amount of contrast medium was used (4. 6 vs 15. 7 mL ; P < 0. 001), the procedure caused less pain to the patient (3. 2 vs 6. 8, respectively ; on a scale of 1-10 ; P < 0. 001), and was easier for the physician to perform (1. 4 vs 3. 4 ; on a scale of 1-10 ; P < 0. 001).
