Philadelphia Phillies pitcher Zack Wheeler has undergone a successful thrombolysis procedure, which removed a blood clot from his upper body on Monday, the team announced.
Thrombolysis is a ‘treatment that dissolves blood clots to restore normal blood flow. This approach is used in emergencies, such as heart attacks, strokes, and severe blood clots in the lungs or legs,’ per Penn Medicine.
The procedure was performed by Dr. Paul DiMuzio at Thomas Jefferson University Hospital in downtown Philadelphia.
Wheeler’s timeline to return to the field and treatment for the procedure has yet to be determined.
