Back­ground. By meas­uring the diam­eter of the ­aorta and ­iliac ­arteries in ­cadavers, ­this ­study eval­u­ated the pos­sible rela­tions ­between arte­rial diam­eter and age, ­height, ­weight and ­body ­size, com­paring ­these ­results ­with ­those ­reported in the lit­er­a­ture.
­Methods. The ­aorta and ­iliac ­arteries ­were iso­lated in 81 ­cadavers under­going post­mortem exam­ina­tions to ascer­tain the ­cause of ­death. ­External arte­rial diam­eter was ­then meas­ured at ­four set ­points. Infor­ma­tion was ­also col­lected ­regarding the ­gender, ­height, ­weight and ­body ­size of the ­cadavers exam­ined in ­order to deter­mine pos­sible cor­re­la­tions ­with ­aortic diam­eter. The pop­u­la­tion in ques­tion pre­sented “­normal” ­aortas; aneu­rys­matic or dil­a­ta­tion pathol­o­gies of the ­aorta ­together ­with ­aortic rup­tures and dis­secting aneu­rysms, ­severe cal­cifi­ca­tion and sur­gical recon­struc­tion rep­re­sented the cri­teria for exclu­sion ­from the ­study.
­Results. ­Among the ­results ­obtained, it was ­found ­that the arte­rial diam­eter meas­ured at the ­level of the suprar­enal and infra­renal ­aorta and in cor­re­spon­dence ­with the ­left and ­right ­common ­iliac ­arteries was sig­nif­i­cantly cor­re­lated ­with age (p<0.001) at all ­four meas­ure­ment ­points in ­males. The ­same sta­tis­ti­cally sig­nif­i­cant ­result ­emerged ­from a cor­re­la­tion ­between ­aortic diam­eter and age in ­females (p<0.001). The sta­tis­tical anal­ysis of ­mean diam­e­ters in the ­four age ­groups, ­using ­linear regres­sion and var­i­ance anal­ysis, was ­only ­found to be sig­nif­i­cant in ­males (p<0.001).
Con­clu­sions. The ­results of meas­uring arte­rial diam­eter in ­cadavers ­shows ­that the diam­e­ters of the ­aorta and ­iliac ­arteries ­increase sig­nif­i­cantly ­over ­time in ­both ­sexes. The ­mean ­values of aor­toi­liac diam­e­ters are ­larger in ­males com­pared to ­females. More­over, indi­vidual ­size is not sig­nif­i­cant. ­These find­ings may rep­re­sent an inter­esting ­point of ref­er­ence for the diag­nosis of aneu­rys­matic and hypo­plastic dis­eases of the abdom­inal ­aorta, ­taking ­into ­account the effec­tive dis­tri­bu­tion of arte­rial diam­e­ters in the gen­eral pop­u­la­tion.
