My PS tried to aspirate, but when he pressed on my tummy, dark red blood came out of the needle hole. Is this a seroma? (Photo)

Hematomas are initially too thick to aspirate with a needle. They will liquefy over time and can be aspirated later. Some can become infected and require opening the incision to evacuate. In almost all instances, this is a minor problem that is easily correctable and won't affect your long term results.

The dark red color indicates that there was an accumulation of blood (hematoma) in the surgical space below the skin. The dark red color means that it is likely old blood that is now "organizing," or collecting in one area. Sometimes the blood is initially clotted and difficult to aspirate with a needle. A brighter red color would indicate possible ongoing bleeding.  Your surgeon will monitor that area closely. Sometimes repeated aspiration is necessary. If properly manage, it should not cause you any long-term problems or affect your overall results.
