Anatomic Results of PR
The reported primary anatomic success rates of PR vary widely in
published series, ranging from 61% to 90% with an overall single
procedure combined rate of 75.5% – 918/1,215 cases (Table 4.7) [3,
9–18, 26–29]. There does not appear to be a difference between the
selection of tamponade agents with respect to anatomic outcome –
with filtered air, SF 6,and C 3F 8 having similar reported results.
There is no trend toward higher success rates over time. The 84%
primary anatomic success rate reported by Hilton [9] is similar
to the reports by Abecia [15] and Eter [28], with success rates of
82% and 86%, respectively. The overall final anatomic (with reoperations)
success varies between 87% and 100% in this group of
