Question 39

Patient who can't continue indefinite anticoagulation although it would be continued if they could

Answer 39

2021 CHEST guidelines suggest aspirin in patients with an unprovoked proximal DVT or PE who are stopping anticoagulation therapy; however, continued anticoagulation is preferred.

Question 40

Post thrombotic syndrome

Answer 40

Approximately 25% to 40% of patients with symptomatic DVT develop aspects of postthrombotic syndrome and chronic venous insufficiency, which often develop within 2 years of VTE. Symptoms of postthrombotic syndrome include pain, heaviness, swelling, stasis dermatitis, and ulceration in the affected limb. Treatment includes leg exercises, avoiding dependent positions for lengthy periods, and using compression stockings. Emollients and a low-moderate potency topical glucocorticoid may be used for stasis dermatitis

Question 41

How to diagnose ABPA

Answer 41

Measurement of serum IgE against Aspergillus fumigatus

Question 42

Abnormal finding on a stress test

Answer 42

If there are several areas of hypoperfusion, the differential in perfusion between regions might not be adequate to highlight a focal area of ischemia. Reduction or lack of augmentation in poststress ejection fraction and transient cavity dilatation, as in this patient, are indicators of global hypoperfusion and are high-risk features in MPI. Prompt evaluation for coronary disease with cardiac catheterization is indicated.
