Peripheral Flashcards
2 examples of peripheral vascular disease
- Intermittent claudication
- Critical limb ischaemia (severe)
What can occur during ABPI test?
falsely high reading fir diabetes > take a droplers test
Scale for Severe claudication
0-0.4
Scale for normal Claudication
0.9-1.2
What imaging would you use for intermittent claudication and
critical limb ischaemia?
Intermittent claudication- MR angiography
Critical limb ischaemia - CT angiography
What is Foam sclerotherapy?
involves injecting a foam-like substance into varicose veins to collapse them. Minimally invasive.
What is Endovenous Ablation
Endovenous Ablation is another minimally invasive treatment option for varicose veins. It involves using heat energy or laser energy to close off the diseased vein. During the procedure, a thin catheter is inserted into the vein through a small incision. The catheter delivers heat energy (radiofrequency ablation) or laser energy (endovenous laser ablation) to the vein wall, causing it to collapse and seal shut. Blood flow is then redirected to healthy veins
0.8 - 0.9 on ABPI
mild
0.5 - 0.8 on ABPI
moderate
<0.5 on ABPI
Severe disease
Management - cardiovascular risk
clopidogrel 75mg once daily (asprin alternative)
atorvastatin 80mg once nightly
Pain mangement
Naftidrofuryl oxalate, a vasodilator, can alleviate pain in PAD. It should only be prescribed if supervised exercise is ineffective and the patient does not want to be referred for angioplasty or bypass surgery.
A 58 year old man presents to his GP complaining of pain in the right calf when he walks. He states that it improves when he rests. His past medical history includes hypercholesterolaemia, ischaemic heart disease and hypertension. He smokes 40 cigarettes per day. On examination he is obese, and his pulses are difficult to palpate in both feet. What is the most appropriate initial test to perform on this patient?
Ankle Brachial Pressure Index (ABPI)
A 65 year old gentleman presents with a 2 month history of intermittent calf pain. He describes the pain as better in the morning and worse following prolonged physical activity. He is only able to walk 200 metres before the pain begins. He is otherwise asymptomatic. He has a past medical history of hypertension, type 2 diabetes and peripheral neuropathy.
On examination, his dorsalis pedis and posterior tibial pulses are equal bilaterally, and there are no obvious abnormalities. His observations are normal.
What investigation would be most appropriate to confirm the diagnosis?
Duplex ultrasound of femoral arteries
A 65-year-old gentleman presents to the emergency department with a 12-hour history of severe pain in his left leg present at rest. He has a past medical history of type 2 diabetes, hypertension and a previous below-knee amputation of his right leg 2 months ago. The leg appears well-healed on the right side with no obvious complications.
On examination, there is significant wet gangrene of the left foot. His posterior tibial and dorsalis pedis pulses are not palpable. The limb is cold to touch and tender to palpation. There is irreversible ischaemic ulceration present over the mid-shin.
What is the most appropriate management?
Below knee amputation
