Is This Dangerous to Have Such a Large Painful Hematoma After Mini Tummy Tuck and Lipo? (photo)

Yes there appears to be a residual amount of "voluted" blood in your abdomen. Either re operation or interventional radiologic drainage will help. But your surgeon needs to act NOW! 

   A hematoma should always be drained if it is clinically significant.  If there is no distinct fluid collection, sometimes this is not possible.  A chronic fluid collection is not something you want, because this can cause a contour deformity and may have to be surgically removed.  If your surgeon does hundreds of tummy tucks and liposuctions each year, I would trust the judgement of the surgeon.  I cannot determine from pictures alone what should be done.  Kenneth Hughes, MD Los Angeles, CA

As a general rule, a hematoma this large should be evacuated either by surgeon or by aspiration and/or drain placement. I wouldn't make a diagnosis based solely upon the photos, but I do suspect there is more hematoma present.  Make an appointment to see your surgeon. 

Best wishes.
