Old blood in a surgical site is usually a hematoma. These collections differ from normal postoperative swelling and sometimes become apparent after the swelling has resolved. Small collections will resolve over time without intervention. Large hematomas or expanding hematomas typically require surgery. Close follow up with your surgeon is the key.
This is probably old blood and should be cause for alarm.The fact that it is old dark clotted blood means it is not new and expanding.Make sure you follow up with your plastic surgeon.
Please contact your plastic surgeon's office and speak to a nurse and schedule an appointment to discuss your concern with your plastic surgeon. Best of luck!
Very hard to respond in the few parameters you provided. Best to return to see the PS for more explanation...
The pocket of blood is a potentially serious complication. This blood is called a hematoma. Hematomas can ruin the final shape but most importantly can become infected. It sounds like you had the right treatment. Follow your plastic surgeon's advice.

It is possible to have an isolated hematoma after an abdominoplasty. It sounds like you have been treated appropriately. At your next follow up visit I would be certain that your plastic surgeon will recheck this area for a recurrence.
