Aorto-enteric Fistula Following Endovascular Repair of Abdominal Aortic Aneurysm

Aortoduodenal fistula after transperitoneal repair of an inflammatory abdominal aortic aneurysm: A case report

“…An aortoduodenal fistula seldom occurs this early after transperitoneal open aneurysm repair. In Table 1, the postoperative time of presentation of an aortoduodenal or enteric fistula is given [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Chang et al described a patient in 2002 who presented 20 days after emergency surgery because of a ruptured abdominal aneurysm with an aortoduodenal fistula [16].…”

Primary aortoenteric fistula following endovascular aortic repair due to type II endoleak

“…7,11 In contrast, several other early series report infectious symptomatology. 3,4 A recent systematic review of reported cases of AEF following aortic endograft placement lacks specific details about each case, but did demonstrate that most patients will present with more than one complaint. 17 The etiology of AEF formation varies widely in the reported cases as well.…”

“…Existing reported cases of AEF following EVAR have described both infectious and hemorrhagic manifestations with multiple etiologic factors. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] We describe a unique presentation of a primary AEF following EVAR manifested by a subacute gastrointestinal hemorrhage.…”

Aortoduodenal fistula 5 years after endovascular abdominal aortic aneurysm repair with the Ancure stent graft

“…6 One case was described in a patient with active Crohn's disease; fistulization may have resulted from a segment of involved intestine. 7 Finally, two cases were included in a large review of EVAR complications, but no information about the patients or other details were listed. 8 Only two other AEFs have been reported without any antecedent complications after EVAR (Table).…”
