Module - Peripheral Arterial Screening and Microvasculature Diagnostics (SPS131)
Aim of this module
This module provides trainees with the knowledge that underpins this third year specialist module in Vascular Science. It will provide trainees with the knowledge, understanding and practical skills to safely contribute to the diagnosis and screening of peripheral arterial disease (macro and microvascular), abdominal aortic aneursyms and intracranial lesions (for sickle cell). This module will provide trainees with the knowledge, understanding and practical skills to safely contribute to the screening of patients with suspected abdominal aortic aneursym (AAA) and peripheral arterial disease (ABPIs). It will also provide trainees with the knowledge, understanding and practical skills to obtain transcranial Doppler (TCD) images and measurements of the peripheral microvascular system.
Work-based learning outcomes
1. Perform ultrasound scans on patients with suspected abdominal aortic aneurysm (AAA).
2. Perform resting and post-exercise Doppler assessment of patients with suspected peripheral arterial disease.
3. Obtain transcranial Doppler (TCD) spectra of the intracranial cerebrovascular circulation.
4. Obtain measurements of the microvascular system.
Perform an ultrasound scan using B Mode to identify and measure a normal abdominal aorta.
Perform an ultrasound scan using colour Doppler and spectral Doppler to demonstrate the haemodynamics of a normal carotid and vertebral arteries.
Haemodynamics and normal physiology of the aorta.
Perform ultrasound scans to identify and measure an AAA.
Obtain and fully interpret resting Doppler signals from all pedal pulses, measure blood pressure and calculate resting ABPI.
Exercise the patient obtaining and fully interpreting resting and post- exercise ABPI measurements.
Obtain transcranial Doppler spectra of the intracranial cerebrovascular circulation identify the middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA).
Obtain measurements of the microvascular system using thermography, laser Doppler, transcutaneous O2 or nailfold
