Background. The aim of ­this ran­dom­ised pros­pec­tive ­study was to eval­u­ate the rel­a­tive ­risks and advan­tag­es of ­using exter­nal jug­u­lar ­venous ­patch ­graft com­pared to ­PTFE ­patch in carot­id endar­te­rec­to­my.
Methods. Between 1 December 1996 and 31 March 1998, 58 ­patients under­go­ing carot­id endar­te­rec­to­my at the Vascular Surgery Clinic in Padua ­were ran­dom­ly ­assigned to two ­groups: 29 ­with exter­nal jug­u­lar ­venous ­patch (Group A), and 29 ­patients ­with ­PTFE ­patch (Group B). All oper­a­tions ­were per­formed ­under gen­er­al anes­the­sia ­with con­tin­u­ous EEG mon­i­tor­ing and rou­tine dilat­ed use of ­shunt. Every ­patient under­went a ­check-up and ­colour Doppler ultra­so­nog­ra­phy at 6 and 12 ­months. This meth­od was ­used to exam­ine ­both the pres­ence of myoin­ti­mal hyper­pla­sia and the inci­dence of resten­o­sis, as to ver­i­fy the pres­ence of dil­a­ta­tion. Neurological mor­tal­ity and ­minor and ­major ­short- and medi­um-­term neu­ro­log­i­cal mor­bid­ity ­were ­also eval­u­at­ed. The exclu­sion cri­te­ria for Group A includ­ed: an exter­nal jug­u­lar ­vein ­with insuf­fi­cient diam­e­ter and/or the pres­ence of col­lat­er­al branch­es.
Results. No mor­tal­ity or mor­bid­ity was report­ed in ­both ­groups ­with ­regard to ­short-­term neu­ro­log­i­cal com­pli­ca­tions. Operating ­time and bleed­ing ­were sig­nif­i­cant­ly low­er in Group A ­patients. There was 1 ­case of post­op­er­a­tive mor­tal­ity (Group A), and 3 cas­es of ­long-­term mor­tal­ity (2 Group A and 1 Group B). We ­observed one ­case of throm­bo­sis ­with occlu­sion of the arte­ri­al ­axis (Group B) and a ­case of resten­o­sis (Group A) ­caused by myoin­ti­mal hyper­pla­sia ­that ­required ­redo sur­gery. No ­patch rup­tures ­occurred, or for­ma­tion of infect­ed ­false aneu­rysms in ­either ­group. One ­patient (Group B) under­went ­wound revi­sion fol­low­ing a later­o­cer­vi­cal hemat­o­ma on post­op­er­a­tive day 2.
Conclusions. Patch angio­plas­ty ­using exter­nal jug­u­lar ­vein com­pared to ­PTFE ­does not ­expose the ­patient to high­er ­risks and, ­when ­equal ­results are ­achieved, reduc­es bleed­ing and oper­at­ing ­times.
