Vascular Surgery Flashcards
6Ps of Acute Limb Ischemia
Pain (sudden) Pallor Pulselessness Paralysis Paresthesia Perishing cold
Likely cause of acute limb ischemia if it is coupled with arterial fibrillation
Embolus
Painless, pulsatile mass
Aneurysm
Painless, pulsatile mass in the groin
Femoral artery aneurysm
Patient with renal cell carcinoma presents with bluish, bag of worms sensation, dragging pain or painless scrotal swelling
Varicocele
Rx: Reassure or surgery if pain is persistent
Patient with renal cell carcinoma presents with pitting non-tender bipedal edema, dilated veins in the lower abdomen
Inferior vena cava syndrome
Ulcer on the toes or plantar surface of the foot + deep and punched out + surrounded by callous + reduced sensation
Diagnosis?
Causes?
Rx?
Neuropathic “diabetic” ulcer
Causes: DM, pressure points in the bottom of the feet
Rx: remove pressure, manage DM, diabetic foot care
Ulcer on toes, feet, lateral malleolus - irregular, deep and necrotic + unilateral absent or weak pulses + very painfiul + prolonged CRT
Diagnosis?
Risk Factors?
Rx?
Arterial “ischemic” Ulcer
RF: peripheral arterial disease (HTN, smokin, DM)
Young man (25-45) + smoking + extremity ischemia (intermittent claudication, rest pain, ischemic ulcer) + superficial thrombophlebitis + Raynaud’s phenomenon
Buerger’s disease (thromboangiitis obliterans)
66-year old smoker and hypertensive + sudden onset weakness of the right arm + dysphasia + resolved within 24 hours
Likely diagnosis?
Next modality?
Transient Ischemic Attack
Carotid doppler scanning
When to perform carotid endarterectomy?
For male: ICA stenosis > 50%
FOr female: ICA stenosis > 70%
An elderly with recurrent episodes of TIA and loss of consciousness
Carotid artery stenosis
42-year old man below the right clavicle with a pulsatile mass just below the right clavicle. (+) shooting pain and reduced sensation down the right arm; right hand is a bit cold and shows discoloration
Thoracic outlet syndrome
X-ray finding seen in aortic dissection
Widening of the mediastinum
First line investigation for peripheral arterial disease
Duplex ultrasound
Initial step in management of a severely hypotensive patient who is highly suspicious for AAA
Fluid resuscitation (pNSS)
Most appropriate initial investigation for AAA
ultrasound
Deterioration of renal function tests after initiation of ACEi in a hypertensive patient?
Bilateral renal artery stenosis
What anti-hypertensive medication is contraindicated in a patient with bilateral renal artery stenosis?
ACE inhibitors
Associated with Turner’s syndrome, berry aneurysms and neurofibromatosis, patient may present with mid-systolic murmur, nosebleeds, headaches and LL pain on exertion.
Coarctation of the aorta
Major cause of aortic aneurysm
Atherosclerosis
Major cause of aortic dissection
Hypertension
Acutely painful, pale, paralysed, pulseless in a smoker with atrial fibrillation
Acute limb ischemia
Calf pain, relieved by rest with calf non-healing ulcer: cold and pulseless peripheries, with or without history of DM and HTN
peripheral arterial disease
