📝 Podcast Description

🎙️MSRA Podcast:Abdominal Aortic Aneurysm (AAA) — The Silent Ticking Time Bomb 🎙️

When it comes to hidden threats in the body, AAA is rightat the top of the list. Most people don’t even know it’s there — until it becomesa life-or-death emergency. In this episode, we break down everything you need to know for exams and real-life clinicalpractice.

🗝️ Key Learning Points

Definition

• AAA = Permanent dilation of the abdominal aorta ≥3 cm in diameter, most commonly below the renal arteries.
• Mnemonic: “Aneurysm = Artery Always Enlarged” (≥3 cm).

Causes & Risk Factors (Mnemonic: AGETHATS)

• Age >65
• Gender (Male)
• Every puff counts (Smoking)
• Tension (Hypertension)
• History (Family history)
• Artery hardening (Atherosclerosis)
• Tissue disorders (e.g., Marfan syndrome)
• Situations (Inflammation, infection)

Pathophysiology

• Weakening of aortic wall due to breakdown of elastic fibres, chronic inflammation, and atherosclerosis.
• Gradual bulging under pressure — risk increases as diameter increases.

Symptoms

• Silent killer: Most AAAs are asymptomatic until rupture.
• Possible vague abdominal/back/loin pain or a palpable pulsatile mass.
• Rupture = Sudden severe pain, collapse, shock (Classic triad).

Differential Diagnosis

• Renal colic, musculoskeletal back pain, GI causes (diverticulitis, gallstones), aortic dissection, iliac aneurysm.

Investigations

• Screening & diagnosis: Abdominal ultrasound (quick, non-invasive, gold standard for screening).
• Pre-op/rupture: CT angiography for surgical planning or suspected rupture.
• Bloods: FBC, U&Es, LFTs, clotting, group & save, ECG, +/- CXR.

Management

• Surveillance for small AAAs:
• 3–4.4 cm: yearly US.
• 4.5–5.4 cm: 3-monthly US.
• Elective repair if:
• Diameter ≥5.5 cm, rapid growth (>1 cm/year), or symptomatic.
• Repair options:
• Open surgical repair (synthetic graft).
• EVAR (Endovascular Aneurysm Repair) — less invasive, stent graft via femoral arteries.
• Medical management: Smoking cessation, blood pressure control, statins, antiplatelets, manage comorbidities.
• Rupture = Emergency surgery, resuscitation.

Complications

• Rupture (massive internal bleeding, ~80% mortality)
• Aortic dissection
• Peripheral embolisation (limb ischaemia)
• Graft complications (endoleak, infection)
• Compression of nearby structures (ureters)

Prognosis

• Excellent if small and managed proactively.
• Large, untreated = high rupture and mortality risk.
• After elective repair: ~70% 5-year survival.
• Ruptured AAA: <50% survive to hospital discharge even with surgery.

Revision Pearl:

AAA = Silent until it isn’t. All men 65+ need an ultrasound. Rupture? Think pain + collapse + shock = 999!
