Purpose:We investigated the perioperative and long-term outcome in both CAS and CEA cases separating acute and chronic phase operations for each procedure.
Methods:In total, 103 consecutive patients who underwent some revascularization procedure from January 1998 to October 2006 at our deparment were enrolled. The CAS cases amaunted to 52 (chronic cases, 48; acute cases, 4) and the CEA cases to 51 (chronic cases: 47; acute cases: 4).
Results:The perioperative outcome of chronic operations for both procedures was favorable; the morbidity rate was 2.1% and the mortality rate was 0% in both procedures. On the other hand, the perioperative outcome of acute operations appesred to be worse than the chronic one; that is, the morbidity rate was 25%, while the mortality rate was 0% in both procedures. Over the long-term follow-up period, both procedures revealed no infarction at both timings of the operation. Occurrence of other disorders that impaired the ADL was observed in 7.9% of chronic CAS cases and in 14% of chronic CEA cases. In contrast, acute operation cases revealed no other complications in both CAS and CEA. There were few cases that had ADL impairment due to cardiac diseases among our patients, This may have been attributable the fact that in our protocol, all patients underwent cardiological consultation before the operation and were managed even after leaving hospital. Conclusion: Our data suggest that CAS could be performed securely, and revealed good results on long-term follow-up. It could also be expected to represent an alternative for high-risk patients of CEA.
