Polytetrafluoroethylene grafts for carotid repair

Carotid Graft Replacement of the Stenotic Carotid Artery

“…Authors performed this procedure in 110 patients, indicated it in case of extensive atherosclerotic disease in 45 (41%), while using it also for reconstruction in case od restenosis (16.4%) or kinking (26.4%). There were some other authors reporting usage PTFE graft with similar patency of 95-97% in the long term [40,41]. The only author that used Dacron graft was Valdeniz with results comparable to those published with PTFE [42].…”

Carotid replacement with Dacron graft in 292 patients

“…In case of advanced atherosclerotic process extending on longer segment beyond carotid bifurcation, carotid graft replacement might be a potential solution to address possible issues and achieve reconstruction. 3–12 Similar is in case of exceptionally thin wall following endarterectomy or carotid restenosis after CEA/CAS. Once it comes to graft replacement, selection of conduit is important.…”

“…Additionally the outcome of CEA can be jeopardised in case of exceptionally thin arterial wall remaining after endarterectomy or plaque disruption during eversion CEA. 3–12,19–21 In patients with carotid restenosis, patch infection, carotid aneurysm, post-irradiation arteritis or in case of carotid traumatic injury it is rather difficult or impossible to perform CEA at all. In those cases, the graft interposition is a potential solution to address possible issues and achieve reconstruction.…”

“…Several studies evaluated the use of saphenous vein 5,6 as well as synthetic polytetrafluoroethylene (PTFE) grafts for carotid reconstructions. 3,4,9–12 In the current literature, there is scarce data regarding the use of polypropylene (Dacron) grafts for carotid revascularisation due to extensive atherosclerotic disease. Comparison between the conduits implanted in other position is still present and controversial.…”

Karotisverletzungen

“…Wenn solche Verletzungen in kleineren Hospitälern versorgt Manchmal ist es auch sinnvoll, die A. carotis externa für einen Ersatz der A. carotis interna zu verwenden. Wenn autologes Material nicht zur Verfügung steht, können künstliche Gefäûprothesen eingesetzt werden [1,8]. Bei der Karotisrekonstruktion speziell älterer Patienten mit arteriosklerotischen Veränderungen kann gelegentlich die Endarterektomie erforderlich werden.…”
