Background. Final ­events pre­ced­ing aneu­rysm rup­ture are not com­plete­ly known. The cur­rent study ­relates to incom­plete aor­tic aneu­rysm wall ­lesions (i.e. mal­a­cia, dark stain­ing and blebs or blis­ters) as pos­sible sites of aneu­rysm rup­ture.
Methods. 162 abdom­i­nal aor­tic aneu­rysms, resect­ed ­between 1988 and 1996, have been ­reviewed and 27 cases of aneu­rysms pre­sent­ing wall thick­ness ­lesions are report­ed. The ­lesions were sched­uled by oper­a­tive ­reports and com­pared to ultra­sound and CT scans.
Results. The ­authors clas­si­fy aor­tic aneu­rysms into three phas­es, depend­ing on the ­degree of wall degen­er­a­tion viz 1. Flawless wall aneu­rysms. 2. (a-b-c) Aneurysms with intra­pa­rie­tal ­lesions. 3. Ruptured aneu­rysms.
Conclusions. It is con­clud­ed that stage 2 aor­tic aneu­rysms must be urgent­ly oper­at­ed on. They carry a high sur­gi­cal risk and, con­se­quent­ly, high­er mor­bil­ity and mor­tal­ity com­pared with stage 1 aneu­rysms.
