Pocket Hematoma In Simple Terms:

• A pocket hematoma is essentially a bad bloated bruise that appears on the surface of your skin, and if it remains untreated it can lead to serious infections and can even be fatal.
• Pocket Hematomas due to implantations of cardiac devices were seen to occur more frequently in individuals who have coronary artery disease or heart failure than in those who do not possess any of those conditions. [1]
