Q

Week 219 - Haemoptysis: What are the three broad vascular sources of haemoptysis? Give a brief description of each.

A

Doppler Ultrasound

24
Q

Week 219 - Haemoptysis: What does a d-dimer test signify?

A

D-dimer is a breakdown product of cross-linked fibrin, it is elevated in thromboembolism.

25
Q

Week 219 - Haemoptysis: What is the management of DVT?

A
  • S/C heparin until diagnosis confirmed.
  • USS
  • Continue heparin / start anti-coagulants
  • Stop heparin when INR 2.5
  • Warfarin for 3/12 if clear cause
  • Warfarin for 6/12 if no clear cause.
26
Q

Week 219 - Haemoptysis: What is the difference in pathophysiology between a large and small clot? (In terms of where it lodges)

A
  • Large clot - Bifurcation of pulmonary arteries > haemodynamic compromise.
  • Small clot - Distal airways > infarction > pleuritic pain.
