Vascular disorders

Question 1

What is the prevalence of Raynaud’s Phenomenon in women compared to men?

Answer 1

Women - 5-20% compared
Men - 4-14%

Question 2

What does a digital-brachial pressure index below 0.7 indicate?

Answer 2

A digital-brachial pressure index below 0.7 indicates a significant occlusive problem, critical for diagnosing hand ischemia.

Question 3

How does Hypothenar syndrome typically present?

Answer 3

Hypothenar syndrome typically presents with ulnar artery thrombosis or occlusion due to repetitive trauma, though pseudoaneurysms can occur.

Case reports highlight these vascular changes.

Question 4

Is Sildenafil effective in treating Raynaud’s disease?

Answer 4

Yes, Sildenafil reduces attack frequency and aids ulcer healing in Raynaud’s disease, particularly in severe cases.

Question 5

How does occupational exposure affect Raynaud’s Phenomenon in men?

Answer 5

Occupational use of vibrating tools increases Raynaud’s incidence in men, altering prevalence patterns.

Question 6

Can Hypothenar syndrome cause pseudoaneurysms?

Answer 6

Yes, though rare, pseudoaneurysms can develop in Hypothenar syndrome from ulnar artery trauma.

Case reports confirm this atypical presentation.

Question 7

Why distinguish between primary and secondary Raynaud’s Phenomenon?

Answer 7

Secondary Raynaud’s links to diseases like systemic sclerosis, necessitating specific management.

Question 8

Which occupational groups are at risk for Hypothenar syndrome?

Answer 8

Mechanics and others using hammering tools face higher risk due to repetitive ulnar artery trauma.

Research identifies these trauma-related occupations.

Question 9

How does Sildenafil compare to other Raynaud’s treatments?

Answer 9

Sildenafil is used off-label for severe cases with digital ulcers when other treatments fail.
