ABSTRACT

Results Parodi endograft (PE) Of 103 patients treated from September 1990 to March 1996 in our institution, 51 patients underwent aortic tube graft replacement, with 8 patients having only one proximal stent, and 45 aortoiliac stent grafting. However, the following description refers to the results after 5 years of implantation. Patients with acute and mid-term failures were not included. This limitation produced a case selection. Only the survivors are analyzed; even patients whose cause of death was related to the treatment were not considered if the episode occurred within the first 5 years after the treatment. The aortoaortic endograft design failed in 12 patients out of 15 (80% failure rate). All failures were due to the development of a distal endoleak (Figure 48.2). The aneurysm increased in size in eight patients (43.7 ± 6.3 mm vs. 52.8 ± 11.9 mm, p = 0.08); the aneurysm sac remained the same size in 3 and decreased in another 4 patients (44.3 ± 8.6 mm vs. 36.7 ± 6.1 mm, p = 0.2). Two patients with aneurysm shrinkage presented distal endoleaks, whereas 3 patients (20%) had a successful durable exclusion: the size of the aneurysm decreased in 2 of them and the other patient did not register any diameter change. The aortoaortic design was abandoned in 1994.
