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:
-
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.
-
-
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.
-
-
Carotid Artery Disease:
-
Carotid artery stenosis >50% in patients with transient ischemic attacks (TIAs) or strokes.
-
Asymptomatic carotid artery stenosis >80% in select cases.
-
-
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.
-
-
Non-healing Wounds of the lower limbs:
-
Chronic, non-healing wounds, especially in patients with associated vascular risk factors.
-
-
Varicose Veins:
-
Severe, symptomatic varicose veins causing pain, skin changes, or ulceration.
-
-
Acute Limb Ischemia:
-
Sudden onset of severe limb pain, pallor, pulselessness, paresthesia, or paralysis.
-
-
Vascular Trauma:
-
Penetrating or blunt vascular injuries, such as gunshot wounds or motor vehicle accidents.
-
-
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.
