One-liner

Episode 610 is a high-yield integration episode covering breast imaging guidelines (age/risk stratification), the interpretation of benign vs. malignant findings on mammography and ultrasound, management protocols for central venous catheter complications, and critical decision points in acute thromboembolic events like DVT, PE, and Acute Limb Ischemia.

High-yield summary

Breast Screening: Mammogram is standard screening age 40; Ultrasound is preferred for evaluating masses in women <30.
High Risk Screening (BRCA): Annual Breast MRI is required from ages 25–30, followed by annual mammography starting at age 30.
Vascular Access: Central venous catheters are indicated for long-term antibiotics, TPN, or chemotherapy; the most common complication of TPN is central line associated bloodstream infection.
Thromboembolism Management: IVC filters are mandatory when a patient has DVT/PE and an absolute contraindication to anticoagulation (e.g., recent major hemorrhage).
Acute Limb Ischemia: Initial management involves anticoagulation, followed by CT angiogram; if embolectomy is not available, TPA can be used.
Reprefusion Injury: Occurs when restoring blood flow to ischemic tissue, leading to rhabdomyolysis and hyperkalemia; treatment requires immediate calcium gluconate administration.

Learning objectives

Differentiate appropriate breast imaging modalities based on patient age and risk factors.
Recognize the classic signs and symptoms of benign versus malignant breast lesions using physical exam and imaging findings.
Identify indications for central venous catheter placement and common complications (e.g., TPN line infection).
Determine the correct management sequence for acute thromboembolic events, including when to use IVC filters vs. anticoagulation.
Understand the pathophysiology and immediate management of reperfusion injury following prolonged ischemia.
