Dr. Sean Crawford provides expert diagnosis and treatment for a wide spectrum of vascular conditions, including:

Arterial Occlusive and Stenotic Diseases

Dr. Crawford treats conditions characterized by narrowing or blockage of arteries, restricting blood flow to vital organs and limbs.

• Peripheral Artery Disease (PAD) / Peripheral Vascular Disease (PVD): Narrowing of the arteries primarily supplying the legs and feet, leading to claudication (pain on exertion), rest pain, or non-healing sores.
• Mesenteric Ischemia (Acute or Chronic): Acute mesenteric ischemia is a surgical emergency requiring rapid revascularization.

Aortic and Other Arterial Aneurysmal Diseases

Dr. Crawford's management focuses on monitoring smaller aneurysms and intervening to repair larger or symptomatic ones to prevent catastrophic bleeding.

• Aortic Dissection: A serious condition in which the inner layer of the aorta tears, causing blood to flow between the layers of the aortic wall, forcing the layers apart.
• Abdominal Aortic Aneurysm (AAA): A localized enlargement of the abdominal aorta, which can rupture if it grows too large, leading to life-threatening internal bleeding.

This list is not exhaustive. For a comprehensive evaluation of your vascular health, a consultation with Dr. Sean Crawford is necessary.

• Varicose Vein Treatment (Minimally Invasive and Surgical): Comprehensive management of varicose veins, including endovenous laser ablation (EVLA), radiofrequency ablation (RFA), and sclerotherapy.
• Upper Extremity Arterial Disease Management: Surgical bypass or endovascular therapy for conditions like subclavian steal syndrome or upper extremity claudication.
• Peripheral Artery Disease (PAD) Management - Surgical & Endovascular: Treatment of blockages in leg arteries causing claudication, rest pain, or non-healing ulcers.
• Non-Invasive Vascular Laboratory Interpretation (e.g., Duplex Ultrasound): Expert interpretation of ultrasound and other non-invasive tests to diagnose blockages, aneurysms, or venous insufficiency.
• Renal Artery Stenosis Treatment: Surgical bypass for complex renal artery disease.
• Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) Management - Select Interventions: Interventional treatments for extensive DVT or massive PE, such as catheter-directed thrombolysis or thrombectomy (often in collaboration with interventional radiology).

What does a Vascular Surgeon like Dr. Crawford specialize in?

Dr. Crawford is a Vascular Surgeon, a physician with expertise in diseases of the circulatory system outside of the heart. This includes managing blockages in arteries (like peripheral artery disease or carotid artery disease), aneurysms (abnormal bulges in arteries like the aorta), varicose veins, deep vein thrombosis (DVT), and issues with dialysis access. They use medical therapy, catheter-based interventions, and traditional surgery to improve blood flow and prevent serious complications. a Vascular Surgeon, specializing in the diagnosis and comprehensive management of diseases affecting the arteries, veins, and lymphatic system, utilizing medical, endovascular, and open surgical techniques.

Dr. Crawford will provide detailed post-procedure instructions and a personalized recovery plan.

What are some common conditions treated by Dr. Crawford?

As a Vascular Surgeon, Dr. Crawford manages many conditions involving blood vessels. These frequently include blockages in arteries (atherosclerosis) affecting the legs, neck, or abdomen; aneurysms (weak, bulging arteries); problems with veins such as varicose veins or blood clots (DVT); and creating or repairing sites for dialysis access.

What is the difference between endovascular and open surgery, and does Dr. Crawford perform both?

Open vascular surgery requires a larger incision to expose the blood vessel for repair. Endovascular procedures are less invasive, using catheters and wires inserted through small access points to treat the problem from inside the vessel with balloons or stents.
