PV card: Diagnosis of DVT (ACCP guidelines)

DVT

A patient presents with an asymmetric leg with trace pitting edema in the affected leg. What is your diagnostic approach to such a patient? What is the role of D-dimer and ultrasound (U/S)? Does this match the 2012 American College of Chest Physicians (ACCP) guidelines?

The first step is to determine your patient’s pretest probability because the recommendations vary based on risk. I can tell you that many ED patients come in with a Wells score of 1-2, which places them in the “moderate pretest probability” category. There are 2 approaches you can take based on the availability of resources at your site (high-sensitivity D-dimer or U/S) and the patient’s comorbidities. Are you referring your patient for a repeat outpatient ultrasound, if warranted?Walk through various patient scenarios to see how the D-Dimer and U/S come into play.

Patwari Academy videos: Low risk chest pain

One of the most common complaints in the Emergency Department is chest pain. Is it something serious? How do I risk-stratify patients with potential acute coronary syndrome? What should I be thinking of and not missing?

Rahul goes over the low-risk chest pain patient in 2 great, short teaching videos, based partly on the 2010 AHA/ACC Guideline for ACS risk stratification.

2-hoursBottom Line 1

For ED patients presenting with undifferentiated chest pain, a TIMI score of 0, together with a non-ischemic EKG, and a negative cTnI at 0 hours and 2 hours, can identify patients at very low-risk for having a major adverse cardiac event (MACE) in 30 days.
