"Liver clot" - a rare periodontal postsurgical complication

Indian J Dent Res. 2012 May-Jun;23(3):419-22. doi: 10.4103/0970-9290.102244.


Bleeding is a common sequela of oral and periodontal surgery. Generally, bleeding is self-limiting. Following traumatic injury or surgical procedures, hemorrhage can range from a minor leakage or oozing at the site, to extensive bleeding leading to complete exsanguinations. Significant postsurgical hemorrhage following periodontal surgery is uncommon due to the primary closure of the soft tissues. This case report describes the unique formation of a "liver clot" or "currant jelly clot" following periodontal flap surgery. The likelihood of this may be attributed to many factors, like infection, intrinsic trauma, presence of foreign bodies like splinter of bone, a fleck of enamel, or a piece of dental restorative dressing material that may cause repeated, delayed organization of blood coagulum.
