When to Refer a Patient to a Vascular Surgeon

​

Vascular surgery is a specialised medical field that focuses on the diagnosis and treatment of disorders affecting the blood vessels, excluding those in the heart and brain. As a general practitioner or other specialist you play a crucial role in identifying patients who may benefit from the expertise of a vascular surgeon.

 

This information provides guidance on when to consider referring a patient to a vascular surgeon and common conditions/symptoms that warrant such referrals.

​

When to Refer a Patient to a Vascular Surgeon:

1. Peripheral Arterial Disease (PAD):

   • Symptomatic PAD with claudication (pain or cramping in the legs while walking).

   • Critical limb ischemia with rest pain, non-healing wounds, or gangrene.

   • Decreased or absent peripheral pulses in the lower extremities.

2. Aneurysmal Disease:

   • Abdominal aortic aneurysm (AAA).

   • Thoracic aortic aneurysm (TAA) of any size with associated risk factors or symptoms.

   • Popliteal artery aneurysm or aneurysms involving other peripheral arteries.

3. Carotid Artery Disease:

   • Carotid artery stenosis >50% in patients with transient ischemic attacks (TIAs) or strokes.

   • Asymptomatic carotid artery stenosis >80% in select cases.

4. Venous Disease:

   • Deep vein thrombosis (DVT) with high risk for complications, such as extensive clot burden or phlegmasia.

   • Chronic venous insufficiency with skin changes, ulcerations, or recurrent cellulitis.

   • Upper extremity DVT, which could be due to venous thoracic outlet syndrome (VTOS).

   • Pelvic congestion syndrome, particularly when common alternative causes have been ruled out by gastroenterology and gynaecology.

5. Non-healing Wounds of the lower limbs:

   • Chronic, non-healing wounds, especially in patients with associated vascular risk factors.

6. Varicose Veins:

   • Severe, symptomatic varicose veins causing pain, skin changes, or ulceration.

7. Acute Limb Ischemia:

   • Sudden onset of severe limb pain, pallor, pulselessness, paresthesia, or paralysis.

8. Vascular Trauma:

   • Penetrating or blunt vascular injuries, such as gunshot wounds or motor vehicle accidents.

9. Complex Vascular Access:

   • Patients requiring dialysis access, especially for fistula creation or management.

​

Common Symptoms/Red Flags:

• Unexplained leg pain or weakness.

• Cold, pale, or discolored extremities.

• Rapidly expanding or pulsatile masses.

• Bruits over major arteries.

• Non-healing wounds or ulcers.

• Sudden-onset severe headache or visual disturbances (suggestive of carotid disease).

• Swelling, tenderness, or redness of the extremities (suggestive of DVT).

 

Additional Considerations:

• Evaluate and manage modifiable risk factors, such as hypertension, diabetes, smoking, and hyperlipidemia, before referral.

• Coordinate care with the vascular surgeon for urgent cases, such as acute limb ischemia or ruptured aneurysms.

• Ensure clear communication and thorough medical records transfer to the vascular surgeon for a seamless transition of care.

​

Referring patients to a vascular surgeon at the appropriate time is essential for the early diagnosis and optimal management of vascular conditions. Timely referrals can significantly improve patient outcomes and prevent potentially life-threatening complications.

 

Collaboration between general practitioners and vascular surgeons is vital in providing comprehensive care to patients with vascular disorders.
