Aim and back­ground. The aim of ­this ­study was to eval­u­ate the ear­ly and ­late ­results in a ­series of ­patients ­with abdom­i­nal aor­tic aneu­rysms under­go­ing endo­vas­cu­lar treat­ment ­using a trans­fe­mo­ral ­approach, ­with implan­ta­tion of mod­ular bifur­cat­ed Medtronic/AneuRx endo­vas­cu­lar ­grafts.
Methods. Between January 1997 and March 1998, at the Department of Vascular Surgery of the University of Milan – Ospedale Bassini in Cinisello B., a ­total of 22 Medtronic/AneuRx endo­vas­cu­lar ­grafts ­were implant­ed dur­ing the treat­ment of infra­ren­al abdom­i­nal aor­tic aneu­rysms ­with a ­mean diam­e­ter of 50 mm (­range 35-67). The ­mean age of the 23 ­patients (21 ­males and 2 ­females) was 73 ­years (59-86). The ­mean oper­at­ing ­time was 173 min­utes (120-240) ­with a ­mean ­blood ­loss of 765 ml (100-2000). All ­patients under­went con­trol CT at 72 ­hours, 6 and 12 ­months ­after sur­gery.
Results. No ear­ly or ­late com­pli­ca­tions are report­ed in 20 ­patients ­with cor­rect implan­ta­tion of the endo­vas­cu­lar ­graft and com­plete exclu­sion of the aneu­rysm. The ­only ­death in ­this ­series was not cor­re­lat­ed to the ­graft. Complications includ­ed a mas­sive embol­isa­tion ­with ampu­ta­tion at the ­thigh and one ­case of con­ver­sion to ­open sur­gery. Three cas­es of endo­leaks are ­still ­being mon­i­tored.
Conclusions. The pre­lim­i­nary ­results ­obtained by ­this cen­tre ­using the mod­ular Medtronic/AneuRx endo­vas­cu­lar ­graft ­system ­have ­been sat­is­fac­to­ry. The flex­ibil­ity and mod­ular­ity of the ­system ­enable it to be ­used in a ­large num­ber of cas­es of abdom­i­nal aor­tic aneu­rysm, ­with accept­able com­pli­ca­tion ­rates. The ­authors ­affirm ­that ­this ­system is a val­id alter­na­tive to tra­di­tion­al sur­gery for abdom­i­nal aor­tic sur­gery.
