From the Guidelines
The management plan for a patient requiring urgent referral to vascular surgery for review should prioritize immediate stabilization and prompt specialist evaluation, as delays can lead to significant morbidity and mortality. The most recent and highest quality study 1 emphasizes the importance of managing patients with vascular diseases by a team of experts in a facility with emergency access to these services.
Initial Assessment and Stabilization
When referring a patient to vascular surgery, it is crucial to first assess and manage life-threatening conditions by ensuring airway patency, adequate breathing, and circulatory support with IV access and fluid resuscitation if needed. Administering appropriate pain management using medications like morphine 2-4mg IV or fentanyl 25-50mcg IV titrated to effect is also essential.
Specific Considerations for Vascular Conditions
For patients with suspected acute limb ischemia, initiating anticoagulation with unfractionated heparin (80 units/kg bolus followed by 18 units/kg/hr infusion) unless contraindicated is a critical step, as supported by the principles outlined in studies like 1. Obtaining relevant imaging studies such as duplex ultrasound, CT angiography, or MR angiography based on the suspected vascular condition is also vital for accurate diagnosis and treatment planning.
Communication and Referral
Documenting and communicating critical information including onset and progression of symptoms, relevant medical history, medication list (especially anticoagulants), and vital signs is paramount. Contacting the vascular surgery service directly rather than placing a routine consult, clearly communicating the urgency and providing a concise clinical summary, is recommended, as emphasized by the need for prompt evaluation and treatment in vascular emergencies 1.
Multidisciplinary Approach
A multidisciplinary approach involving experts in vascular diseases, surgery, cardiology, critical care medicine, radiology, infectious diseases, and microbiology is essential for optimal patient outcomes, as highlighted in 1. This team should work together to provide comprehensive care, including surgical interventions, revascularization procedures, and management of complications, always prioritizing the patient's morbidity, mortality, and quality of life as the primary outcomes.
From the Research
Management Plan for Urgent Referral to Vascular Surgery
- The management plan for a patient requiring urgent referral to vascular surgery for review involves several steps, including noninvasive vascular testing to confirm the diagnosis and determine the severity and extent of the disease 2.
- The ankle-brachial index (ABI) is a commonly used noninvasive test for diagnosing peripheral arterial disease (PAD), but it has a moderate predictive value and normal range outcomes cannot be taken to infer the absence of PAD 3.
- Further noninvasive tests such as exercise studies or pulse volume waveforms should be considered if diagnostic uncertainty exists 3.
- Photoplethysmography (PPG) and continuous-wave Doppler ultrasound (CWD) can be used as complementary tests to ABI in detecting stenotic peripheral arterial disease 4.
- A multicuff oscillometric device can be used to measure ABI, which has excellent diagnostic performance and reproducibility compared to the Doppler method 5.
- The use of ABI in peripheral vascular interventions for claudication is recommended, but its use is not universal and its impact on functional outcomes is unclear 6.
Diagnostic Tests
- Noninvasive vascular testing, including ABI, segmental limb pressures, pulse volume recordings, duplex ultrasonography, computed tomography angiography, and magnetic resonance angiography 2.
- ABI, PPG, and CWD can be used to detect stenotic peripheral arterial disease 4.
- Multicuff oscillometric device can be used to measure ABI 5.
