Symptoms  Pain 96 of patients Sudden severe onset Tearing, ripping, sharp, stabbing Migrating pain (17)Symptoms Pain 96% of patients Sudden severe onset Tearing, ripping, sharp, stabbing Migrating pain (17%) Location • Anterior only: ascending aorta in 90% • Interscapular only: descending thoracic aorta in 90% • Neck, throat, jaw, face: ascending aorta • Back, abdomen, lower extremities: descending aorta Pleuritic pain • Hemopericardium

Laboratory Findings  Chest X-ray Widening of the aortic silhouette • 81 – 90 Calcium signLaboratory Findings Chest X-ray Widening of the aortic silhouette • 81 – 90% Calcium sign • Intimal calcification from the outer aortic border > 1 cm • Suggestive Pleural effusion • Left side Normal chest X-ray • Up to 12%

Diagnostic Techniques  Contrast-enhanced CT Diagnostic clues • 2 distinct aortic lumen and intimal flap •Diagnostic Techniques Contrast-enhanced CT Diagnostic clues • 2 distinct aortic lumen and intimal flap • 3 -dimensional display by spiral CT – Aorta and branches

Diagnostic Techniques  Contrast-enhanced CT Advantages • Noninvasive • High sensitivity and specificity (96 -100) •Diagnostic Techniques Contrast-enhanced CT Advantages • Noninvasive • High sensitivity and specificity (96 -100%) • Readily available • Thrombus in the false lumen • Pericardial effusion • Branch vessel compromise Disadvantages • Contrast materials

Immediate Medical Management  Blood pressure reduction Goal • Systolic BP: 100 – 120 mm. HgImmediate Medical Management Blood pressure reduction Goal • Systolic BP: 100 – 120 mm. Hg • Heart rate: 60 – 80 / m • Reducing d. P/dt (beta blocker) Pain control • Morphine

Immediate Medical Management  Blood pressure reduction Anticipating aorta surgery • Sodium nitroprusside • Esmolol LabetalolImmediate Medical Management Blood pressure reduction Anticipating aorta surgery • Sodium nitroprusside • Esmolol Labetalol • Alpha and beta blocking Contraindicated to beta blocker • Severe sinus bradycardia, AV block, bronchospasm, congestive heart failure • Diltiazem, verapamil • ACE inhibitors

Definitive Therapy  Surgery Acute proximal dissection Complicated acute distal dissection • Progression with vital organDefinitive Therapy Surgery Acute proximal dissection Complicated acute distal dissection • Progression with vital organ compromise • Rupture or impending rupture (saccular aneurysm) • Retrograde extension into the ascending aorta • Dissection in Marfan syndrome Medical Uncomplicated acute distal dissection Stable isolated arch dissection Stable chronic dissection
