    TECHNICAL NOTES

The use of multi-slice spiral CT to study cervico-maxillo-facial vascular structures

From ­the Chair of Maxillo-Facial Surgery Institute of Radiology “La Sapienza” University, Rome

Carotidography is ­still in ­use to eval­u­ate ­the dis­tri­bu­tion of vas­cu­lar struc­tures in ­the ­head ­and ­neck, as ­well as ­their involve­ment in intrin­sic or extrin­sic di-s­eas­es. The exe­cu­tion pro­ce­dure ­for ­this meth­od ­make it an inva­sive diag­nos­tic tech­nique; ­though ­its ­use is ­now ­safe, ­bed ­rest is ­required ­and ­the ­patient is ­exposed to ­the ­risk of com­pli­ca­tions ­that, ­though min­i­mized by ­the evo­lu­tion of ­the mate­ri­als ­used, ­must ­not be under­es­ti­mat­ed. The selec­tiv­ity of ­the exam­ina­tion where­by ­the vas­cu­lar struc­tures ­are stud­ied ­does ­not ­afford, ­except indi­rect­ly, eval­u­a­tion of ana­tom­ic ­and top­o­graph­i­cal rela­tions ­with ­the sur­round­ing ­organs. In ­order to ­achieve a cor­rect ­approach to sur­gi­cal prob­lems, be ­they of diag­no­sis, planning ther­a­py or eval­u­at­ing treat­ment, it is there­fore nec­es­sary ­that angio­gra­phy be asso­ciat­ed ­with diag­nos­tic ­tests (con­ven­tion­al radiog­ra­phy, CT, MR) ­able to vis­u­al­ize ­the mor­pho-struc­tu­ral char­ac­ter­is­tics of ­the ­area ­involved. The ­aim of ­this ­study is to eval­u­ate ­the reli­abil­ity of a ­new appli­ca­tion of instru­men­tal diag­nos­tics: ­using angio­gra­phy ­with mul­ti-­slice hel­i­cal CT to ­study ­the vas­cu­lar­iza­tion of ­the cer­vi­co-max­il­lo-­facial ­area ­and ­its ana­tom­i­cal recon­struc­tion. The ­study ­was per­formed by ana­lys­ing ­and com­par­ing ­the nor­mal ana­tom­i­cal dis­tri­bu­tion of ­the arter­ies ­and ­veins in ­the cer­vi­co-max­il­lo-­facial ­area ­with imag­es ­obtained by angio­gra­phy ­with mul­ti-­slice spi­ral CT. Since ­reports of ­the path­o­log­i­cal imag­es pro­duced by angio­gra­phy ­with spi­ral CT ­are ­not ­yet avail­able in ­the lit­er­a­ture, in ­our opin­ion ­this appli­ca­tion ­must ­for ­the ­moment be asso­ciat­ed ­with con­ven­tion­al carot­i­dog­ra­phy; ­should ­the imag­es pro­duced by ­the ­two ­tests be ­found to be com­par­able, increas­ing ­the reli­abil­ity of ­the ­new meth­od, it is to be ­hoped ­that in ­the ­short- or medi­um-­term it ­may ­become ­more wide­ly ­used ­and ­replace ­the con­ven­tion­al meth­od.
