Background:
As a minimally invasive technique endovascular aneurysm repair (EVAR) reduces the risk of mortality and should be the preferred technique used in older patients. We analysed trends in endovascular and open surgical procedures in patients hospitalized for abdominal aortic aneurysm (AAA) in Germany.
Patients And Methods:
We used national statistics (DRG statistics) published by the Federal Office of Statistics in Germany to calculate the incidence of patients hospitalised with ruptured (rAAA) and elective (eAAA) AAA. In addition, annual procedure rates of endovascular (EVAR) procedures were calculated.
Results:
Incidence rates of eAAA per 100,000 males (females) showed a small increase from 2006 to 2007 but remained almost unchanged with 74.8 (8.8) in 2007 and 74.5 (9.8) in 2009. Incidence rates of rAAA per 100 000 males remained unchanged but showed a decreasing trend in females. The rate of people treated by EVAR increased form 2006 to 2009: in males from 24.0 % to 40.3 % and in females from 17.3 % to 31.0 %. In younger males (55 - 60 years) the increase in those who received EVAR was smaller (from 22.1 % to 33.9 %) than in older males (85 - 90 years) (from 20.4 to 41.6 %). Despite a clear increase in the use of EVAR from 2006 to 2009 there is only a small trend in reduction of the death rates which is more pronounced in rAAA.
Conclusions:
There has been a relevant increase in EVAR procedures for the treatment of AAA in Germany in recent years. Parallel to this increase of EVAR, aneurysm-related in-hospital deaths seem be declining slightly. A causal relationship between these trends remains to be proven.
