We thank Ellis et al. for their comments and interest in our report.

At the time of the manuscript submission (June 2003), the literature search was up-to-date. Ellis et al. have since published an identical case in this journal [1] and not referring to this in our report is regretted.

In the reported patient, an 18-month follow-up computed tomography scan has not revealed a recurrent endoleak. However, we have also encountered recurrence of the endoleak 9 months following thrombin injection in the subsequent patient. Although we think this might be related to the larger size of the aneurysm sac as compared to the first patient, this is speculative. Due to significant patient comorbidity, a repeat thrombin injection is planned.

The experience with this technique is limited and the results are at present anecdotal. Our own experience is restricted to these two cases. Any relevant information of longer-term outcome for this technique is welcome.
