Vascular surgeons are medical doctors who specialize in diagnosing and treating conditions related to the vascular system, which includes arteries, veins, and lymphatic vessels. They perform surgeries to address issues such as aneurysms, varicose veins, and peripheral artery disease. Their expertise helps improve blood flow and prevent complications related to vascular diseases. In addition to surgical procedures, vascular surgeons also use non-invasive techniques like ultrasound and angiography to assess blood vessel health. They often work closely with other specialists, including cardiologists and interventional radiologists, to provide comprehensive care for patients with vascular conditions.
