Study Notes
Aortic Aneurysm
- Dilation of the aorta exceeding 50% of its normal diameter.
- Risk factors include atherosclerosis, smoking, and hypertension.
- Often asymptomatic, but rupture causes severe back or abdominal pain, and hypotension.
- Diagnosis: Ultrasound (screening), CT/MRI (pre-operative planning).
- Treatment: Monitoring if the aneurysm is 5.5 cm or smaller and not causing symptoms.
Aortic Dissection
- A tear in the inner lining (intima) of the aorta, creating a false lumen.
- Characterized by severe tearing chest or back pain, pulse deficits, and blood pressure discrepancies between arms.
- Chest X-ray: widened mediastinum; CT angiography: intimal flap.
- Treatment: Type A (ascending): emergent surgery; Type B (descending): medical (beta-blockers, nitroprusside).
Arterial Embolism/Thrombosis
- Acute blockage of an artery by a clot (thrombus) or embolus.
- Six "Ps" of presentation: pain, pallor, pulselessness, paresthesia, paralysis, and poikilothermia (a change in body temperature).
- Diagnosis: Doppler ultrasound, CT angiography.
- Treatment: anticoagulation (heparin), thrombectomy, thrombolysis.
Arteriovenous Malformation
- Abnormal connection between an artery and a vein.
- Symptoms vary by location and can include seizures, bleeding, and bruits (abnormal sounds).
- Diagnosis: Magnetic resonance imaging (MRI), angiography.
- Treatment: observation if asymptomatic; surgery or embolization if symptomatic.
Deep Venous Thrombosis
- Clot formation in deep veins, most commonly in the lower extremities.
- Presents with unilateral leg swelling, pain, redness (erythema), and warmth.
- Diagnosis: venous ultrasound, D-dimer blood test.
- Treatment: anticoagulation (heparin initially, followed by warfarin or direct oral anticoagulants- DOACs).
Giant Cell Arteritis
- Chronic inflammation of large and medium-sized blood vessels, often associated with polymyalgia rheumatica (PMR).
- Symptoms: headache, jaw pain/difficulty chewing (claudication), vision loss, and scalp tenderness.
- Diagnosis: elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), temporal artery biopsy.
- Treatment: high-dose corticosteroids, administered immediately.
Peripheral Artery Disease
- Atherosclerosis causing narrowing of arteries in the periphery, resulting in ischemia (reduced blood flow).
- Common symptom: intermittent claudication (pain with exercise), decreased pulses, cool extremities.
- Diagnosis: Ankle-Brachial Index (ABI).
