Outpatient single-session pulmonary arteriovenous malformation embolization.

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Pulmonary Medicine

Background:

• Pulmonary arteriovenous malformations (PAVMs) are often treated with embolization.
• Traditional inpatient embolization is costly and inconvenient.
• Hereditary hemorrhagic telangiectasia (HHT) patients frequently have multiple PAVMs.

Purpose of the Study:

• To evaluate the feasibility and outcomes of outpatient PAVM embolization.
• To assess the success of single-session treatment for multiple PAVMs.
• To determine if outpatient embolization is well-tolerated in HHT patients.

Main Methods:

• Retrospective analysis of 51 patients (15-78 years) with PAVMs, 47 with HHT.
• Outpatient embolization performed in 63 procedures.
• Patients observed for 2 hours post-procedure before discharge.

Main Results:

• 86% (44/51) of patients achieved single-session outpatient embolization.
• 100% success for patients with ≤4 PAVMs.
• No postoperative admissions were required.

Conclusions:

• Outpatient PAVM embolization is a safe and effective treatment option.
• Single-session treatment is achievable in over 85% of patients.
• This approach reduces costs and improves patient experience.
