[Hybrid treatment for thoracoabdominal aortic aneurysms].

OBJECTIVE

To review the experience of hybrid conventional open and endovascular treatment of thoracoabdominal aortic aneurysm (TAAA), and evaluate the immediate and long term outcomes.

METHODS

From September 1998 to October 2008, 15 TAAA patients were treated by hybrid-procedures. The mean patient age was 58.7 years (ranged from 44 to 72 years). The aneurysms were Crawford type I in 2, type II in 8, type III in 2, type IV in 3. The median aneurysms diameter was (67.5 +/- 7.5) mm (ranged from 55 to 82 mm). Patients were followed up before dismissal, 3, 6, 12 months later, and annually thereafter.

RESULTS

Two patients were antegrade revascularization, the others were retrograde revascularization. Mean operation time was (8.1 +/- 1.4) h (ranged from 6.8 to 12.7 h), mean blood loss was (956.7 +/- 80.1) ml (ranged from 750 to 3,000 ml). Two patients died during perioperative time, no paraplegia. During follow up revealed shrinkage of aneurysm, no graft migration and paraplegia, but 1 died for acute myocardial infarct.

CONCLUSIONS

Hybrid treatment is a safe and effective option for treatment of TAAA. Immediate and mid-term outcomes are favorable, but long-term surveillance is indefinite.
