POSTINTERVENTIONAL FALSE ANEURYSMS - METH OD, VALUE AND INDICATION OFCOLOR DOPPLER-GUIDED COMPRESSION TREATMENT

In a prospective 6-year study including 155 pts. with false aneurysm ( FA) after peripheral interventions, treatment by color doppler-guided compression (CDGC) was evaluated. Diagnosis and treatment were perform ed 1-42h (mean. 21.5 h) after intervention, using 7.5 MHz transducers. The technique was to apply pressure on the tract connecting FA and ar tery, to occlude it until thrombosis would induce FA closure. The trea tment was successful in 152/155 cases (98.1%), requiring compression f or 7 to 65 min. (mean: 28.8 min.). In 3/155 pts, (1.9 %) under coumari n therapy (INR>3.0) a second treatment was necessary (INR<2.3) to obta in FS closure. Tile treatment was well tolerated, only 42/155 pts. (27 .1 %) needed analgetics, During CDGC, in 19 cases (5.9%) vagal reactio ns were observed, furthermore 2 FA ruptures (1.3%, without sequelae). 2 cases developed a FA elapse (1.3%), both could be permanently closed by a second CDGC. In conclusion, under the condition of early diagnos is CDGC is a rapid, very effective, safe and non-invasive method to tr eat postinterventional FA. Conservative, interventional or surgical tr eatment is limited to fen cases when CDGC is not feasable (infection, compression syndrome), or not successful.
