) If the fissure is less than .5 cm, use gelatin sponge to stop bleeding. After no bleeding, sew the gelatin sponge on both sides of the sinus to prevent slippage. If compression with gelatin sponge can stop bleeding, but bleeding after finger compression is removed, a layer of periosteum or hat-shaped tendon membrane can be covered on the gelatin sponge and stitched on the dura mater on both sides of the sinus to stop bleeding; (2) For long cracks and neat linear cracks, 5? or 7? suture was sutured intermittently every 2 ~ 3 mm; (3) If the fissure is slightly large and uneven and difficult to suture, cover the fissure with periosteum or hat-shaped tendinous membrane, and compress it for 5 ~ 15 min. If the bleeding stops, sew the edge on the dura mater on both sides of the sinus with silk thread; (4) When the fissure is large and the defect is not suitable for filling or suturing with foreign objects, the adjacent pedicled dura mater flap or cerebral falx flap is turned over and covered on the fissure to repair it, and the parts that cannot be sutured are glued with EC ear-brain glue; (5) For most or all of the upper sagittal sinus fractures, and those located in the first third segment, the two broken ends can be sutured and ligated respectively; Those located in the posterior 2/3 segment should be repaired as much as possible and anastomosed with autologous great saphenous vein or artificial blood vessel.
