Pseudoaneurysms - Definitions: 1. Outpouching of a blood vessel, involving a defect in the 2 innermost layers (tunica intima and media) with continuity of the outermost layer (adventitia) 2. Alternatively, all three layers are damaged and bleeding is contained by blood clot or surrounding structures - Etiologies are multifactorial, including post traumatic, iatrogenic (post catheterization), infection and inflammation, IV drug use, septic emboli and MI - Clinical Presentation: - Increased swelling which may be pulsatile over site of previous needle puncture, surgery or trauma; Anemia in cases of significant blood loss; significant pain - Look for characteristic yin yang sign on doppler - EAST Guidelines in Trauma: - Level 2 recommendation: Patients without signs of hard vascular injury who have abnormal physical examination findings and or ABI <0.9 should have further evaluation to rule out a vascular injury - Consider vascular imaging in patients with delayed (>1wk) bleeding, pain or swelling after a traumatic injury Hiccups: - An involuntary, spasmodic contraction of the diaphragm and intercostal muscles. Diaphragm contraction results in sudden inspiration and ends with abrupt closure of the glottis, generating the “hic” sound - Thorough history and physical exam is key in patients with persistent hiccups (48h to 1 month) - Etiology is broad. Most common causes include GI (overeating, gastric distention, GERD); post operative; diaphragmatic processes (subdiaphragmatic abscess). - CNS processes are a more serious cause. In patients with neurologic symptoms, consider MRI imaging. Patients with dorsal medullary strokes can have hiccups for up to 1 year that are debilitating and recalcitrant to medications. Sign of Lesar Trelat - Explosive onset of multiple pruritic seborrheic keratoses - Rapid increase in size and number - Often have an inflammatory base - An ominous sign of gastrointestinal carcinomas - Most commonly pancreatic, stomach, liver, and colorectal
