[Therapy of acute traumatic vascular injuries using covered stents].
OBJECTIVE
Evaluation of percutaneously implanted covered stents in acute vascular bleeding as therapeutic alternative to conventional surgical treatment.


METHODS
8 patients aged 26 to 83 years with acute vascular lesions caused by traumas, and subsequent haemorrhage, were transferred to our department. Because of general inoperability or difficult surgical access, interdisciplinary evaluation favoured an interventional treatment. In 6 patients stents could be placed percutaneously to the aorta, subclavian and iliac arteries. In one case we had to implant three stents into the thoracic aorta.


RESULTS
In 7 interventionally treated patients the stents could be placed exactly on the lesions (88%). The bleeding could be stopped immediately in 6 cases (75%). In one patient we had to implant successfully two more stents in reintervention (12%). In another patient the available prosthesis was too short, so that the patient had to be referred to the OR for surgical treatment (12%). There were no complications during the treatment.


CONCLUSIONS
First results in the use of covered stents as interventional treatment of acute vascular lesions are encouraging and may represent a possible alternative to surgical therapy in locally limited bleedings, presupposing that all different types and sizes of industrially produced covered stents are available. Further investigations to compare surgical and interventional techniques are warranted.
