Abstract/OtherAbstract:
PURPOSE: To assess the feasibility, complications, and long-term success of embolization of pulmonary arteriovenous malformations (PAVMs) with the AMPLATZER Vascular Plug and AMPLATZER Vascular Plug II.
MATERIALS AND METHODS: The study included 15 consecutive patients (19 embolization episodes) who had embolization of PAVMs between April 2004 and April 2009 with an AMPLATZER Vascular Plug or AMPLATZER Vascular Plug II. There were 4 men and 11 women, with a mean age of 56 years (range 24-74 years). A prospective database of all cases of PAVM embolization is kept in the department. Patient history, detailed procedural records, and clinical and radiological follow-up were reviewed.
RESULTS: Among the 19 PAVMs, an AMPLATZER Vascular Plug was deployed in 11, and an AMPLATZER Vascular Plug II was deployed in 8. The technical success of the procedure was 100% for PAVM occlusion; 30-day mortality in the group was zero. Successful radiologic follow-up with the AMPLATZER Vascular Plug was a mean of 28 months (range 0-60 months) and with the AMPLATZER Vascular Plug II was a mean of 18 months (range 12-36 months). There was one recanalization of an AMPLATZER Vascular Plug 36 months after embolization giving an annual event rate of 0.03 recanalizations per AMPLATZER Vascular Plug or AMPLATZER Vascular Plug II per year. There were no major complications. Clinically, there was one (1 of 18 cases [5%]) immediate complication of chest pain that resolved in 24 hours with simple analgesia. There were no early or late clinical complications.
CONCLUSIONS: The treatment of PAVM with either an AMPLATZER Vascular Plug or an AMPLATZER Vascular Plug II is safe and effective and associated with a low reintervention rate. Further follow-up is ongoing to ensure continued occlusion of treated PAVMs.
