/Referral Guidelines
Vascular Surgery problems are categorised under the following headings:Arterial
Extracranial head and neck disease.Upper Limb.
Thoracic.
Abdomen.
Lower Limb.
Venous
Peripheral.Central.
- Lymphatic
Acquired. / A thorough history and examination is required to determine a specific diagnosis and its degree of urgency. Some appropriate investigation by the referrer will facilitate the referral process.
Risk Factors include:
- Smoking.
- Hyperlipidaemia.
- Diabetes.
- Hypertension
- Family history of aneurysmal disease.
Extent of symptoms and functional impairment.
Extent of stenosis or occlusions
Presence of rest pain / These guidelines are provided (below) to give greater clarity in situations of the primary/secondary interface of care. Clear telephone/fax communication would enhance appropriate treatment.

ArterialExtracranial:
- Carotid Disease.
History of TIAs (localising, global and amaurosis fugax) or stroke.
Examination – evidence of:
- Carotid bruit.
- Peripheral pulses.
- Neurological deficit.
- Cardiovascular assessment.
Manage other risk factors / Refer the following as Category 2 for Vascular specialist assessment:
–Carotid bruit with recurrent symptoms, critical carotid stenosis (greater than 90% by ultrasound).
–Patient with Crescendo TIAs/strokes.
Refer as semi urgent – Category 3 patients with TIAs and stenosis > 70%
Refer as routine – Category 4, patients with isolated TIAs with stenosis less than 70%, asymptomatic carotid bruit with greater than 70% stenosis.
Where there is significant co-morbidity, discussion with the Vascular Service is appropriate prior to referral.
Upper Limb:
- Vasospastic Disease.
- Embolic/occlusive Disease.
Examination:
- Blood pressure taken in both arms.
- Degree of ischaemia.
- Trophic changes.
- Check for cardiac arrhythmia including AF.
- Assess for connective tissue disorder.
Advice in regard to precipitants, eg cold exposure, machinery.
Avoid smoking.
Consider trial of medications such as Nifedipine, nicotinic acid. / Acute ischaemia should be referred immediately for admission – Category 1.
Refer as routine referrals – Category 4, connective tissue disorders when significant pain and/or disability not responding to conservative measures.
Cases with trophic changes should be referred semi-urgently – Category 3.
Thoracic:
–Thoracic Outlet Syndrome. / Standard history.
Related to arterial and venous insufficiency in upper limb and neurological symptoms.
Investigations: Rule out all other pathologies. Consider x-ray of cervical spine, chest x-ray and thoracic outlet. / None. / Routine – Category 4. Referral unless neurological symptoms or prolonged arterial or venous insufficiency when patient should be referred urgently – Category 2.
–Hyperhidrosis. / History of profound sweating of hands and axillae unresponsive to conservative treatment.
Investigations: Thyroid function tests. / Routine – Category 4. Referral for consideration of surgery.
–Thoracic Aortic Aneurysm. / Usually presents from routine chest
x-ray.
Cardiovascular assessment.
Investigations: Routine FBC, glucose, creatinine, electrolytes. / Control risk factors.
CT scan if radiological report recommends. / Refer if large sacular aneurysm greater than 5 cm as semi-urgent – Category 3. Otherwise, refer as routine referral.
Abdomen:
–Aortic aneurysm. / Standard history and risk factors above particularly positive family history.
Abdominal examination: Most significant abdominal aortic aneurysms are palpable.
Investigations: Abdominal ultrasound. Full blood count, glucose, creatinine, electrolytes. / Managing risk factors. / Referral to Vascular Clinic, in male if greater than 3.5 cm and female if greater than 2.5 cm, as routine referrals – Category 4. Surveillance in consultation with General Practice.
Aneurysms 5 cm or greater or tender aneurysms should be referred as semi-urgent, Category 3, to the Vascular Service.
–Renal artery stenosis.
–Mesenteric angina
–Other aneurysms / Referred usually from other specialty services, eg General Medicine, Renal Medicine, Cardiology.
Lower Limb
–Rest pain, ischaemic ulceration, gangrene. / Standard history and risk factors above.
Peripheral pulses.
Investigations: Full blood count, glucose, creatinine, lipids, electrolytes. / Managing risk factors, particularly smoking. / Refer urgently – Category 2.
–Diabetic foot disease. / Standard history and risk factors above particularly genetic factors and collagen disorders.
Peripheral pulses.
Investigations: Full blood count, glucose, creatinine, lipids, electrolytes. / Managing diabetes.
General foot care/podiatry assessment. / Active foot sepsis – Category 2. Refer Category 3 if any worsening of ischaemic state or increasing pain.
–Claudication. / Standard history and risk factors above.
Peripheral pulses.
Investigations: Full blood count, glucose, creatinine, electrolytes. / Managing risk factors, especially smoking. / Severe claudication less than 50 metres – refer as semi-urgent
Claudication more than 50 metres – refer as routine – Category 4.

Venous
PeripheralDeep venous insufficiency.
- Post phletic limb.
- Pain of deep venous valvular incompetence.
DVT
Central
Eg. Pulmonary embolus. / Standard history and examination, particular reference to any history of DVT and in relation to previous surgery, accident or parturition, genetic factors.
History of oestrogen therapy, family history, intercurrent disease (particularly malignancy). / Consider graduated stockings.
None. / Refer Category 3 / Category 4
Only refer if symptomatic.
Immediate referral – Category 1 for assessment and treatment.
Immediate referral – Category 1, to hospital for most central venous conditions.

Lymphatic
AcquiredPost surgery/trauma lymphoedema lymphocoeles. / Standard history and examination.
Consider tropical infections. / Early attention to wounds. / Refer as routine – Category 4.
Congenital
Primary lymphoedema. / Standard history and examination. / Refer as routine – Category 4.
