Not necessarily. Many patients with Deep Vein Thrombosis (DVT) can be treated using advanced minimally invasive procedures such as thrombectomy, catheter-directed thrombolysis, venoplasty, venous stenting, and IVC filter placement. These treatments help restore blood flow, reduce leg pain and swelling, prevent long-term complications, improve mobility, and often avoid the need for major surgery with shorter hospital stays and faster recovery.
