Course of the post-catheterization pulseless arm

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Radiology

Background:

• Post-catheterization brachial artery thrombosis is a known complication.
• The natural course and resolution patterns require further elucidation.
• Non-operative management strategies are frequently employed.

Purpose of the Study:

• To determine the natural course of non-operated brachial artery thrombosis following cardiac catheterization.
• To assess the changes in ischemic arm pressure index over a one-month period.
• To evaluate the correlation between pressure index changes and symptom resolution.

Main Methods:

• Prospective follow-up study of 45 patients with post-catheterization brachial artery thrombosis.
• Serial measurements of Doppler-derived pressure index in the ischemic arm.
• Clinical assessment of arm ischemia symptoms at 30 days.

Main Results:

• A gradual increase in the Doppler-derived pressure index was observed, from 0.51 at occlusion to 0.82 at 30 days.
• The majority of patients (35/45) became asymptomatic within 30 days.
• No significant difference in pressure index changes was noted between symptomatic and asymptomatic groups, making prediction difficult.

Conclusions:

• Non-operated brachial artery thrombosis following cardiac catheterization shows a tendency towards spontaneous resolution and improved perfusion over one month.
• Predicting which patients will experience persistent arm ischemia symptoms is challenging.
• Surgical restoration of blood flow should be considered for all patients diagnosed with brachial artery thrombosis post-cardiac catheterization due to the unpredictability of symptom resolution.
