Q

What is the treatment of choice for PE according to the content?

A

LMWH (Low molecular weight heparin) followed by warfarin.

These patients, and those presenting with massive PE, may require pulmonary angiography (still regarded as the gold standard test). Treatment is anticoagulation, typically with low molecular weight heparin followed by 6 months of warfarin. Thrombolytic therapy is reserved for the acute massive presentation.

What is the first step in a patient with suspected lung cancer?

A

Chest CT

This may involve taking a chest X-ray at the outset. A negative chest X-ray does not nec- essarily exclude lung cancer, particularly where the tumour is in a central airway or is small. Sputum cytol-ogy and serum biochemistry should be arranged. Where the diagnosis of lung cancer is likely, a **chest CT with contrast **is indicated to check for hilar and mediastinal lymphadenopathy (Figure 2). racgp
