Perigraft Seroma of Open Aortic Reconstruction

Successful endovascular treatment of aneurysm sac hygroma after open abdominal aortic aneurysm replacement: A report of two cases

“…[4][5][6] Endograft relining for sac hygroma after EVAR has been reported and has been successful. [10][11][12][13] Our two patients represent the first report, to our knowledge, of successful endograft relining for the management of hygroma after open AAA repair. It is noteworthy that in both cases, a small rim of graft was not relined by endografting.…”

Frequency, risk factors, and management of perigraft seroma after open abdominal aortic aneurysm repair

“…A perigraft collection 3.0-cm or greater in diameter is obviously deviant from a well-healed, incorporated graft. From previous reports 8,9,12 and our own experience operating on patients with a PGS, it is known that PGS material has a jelly-like consistency with a radiodensity usually Ͻ25 HUs. We, therefore, chose 25 HUs as the upper limit for perigraft collections to be considered a seroma on CT scanning.…”

“…Perigraft seromas after prosthetic aortic reconstructions have only rarely been reported; our literature review revealed only 15 cases. [8][9][10][11][12] The 20 patients detailed here represent the largest series to date.…”

“…[8][9][10][11][12] Only 2 cases of a PGS after Dacron graft aortic repair have been reported. 5,14 In the current study, all 20 patients with seromas had PTFE reconstructions.…”

“…Possible predisposing factors highlighted in the literature include improper handling of the graft at the time of reconstruction, 1,3 high blood pressure, low blood viscosity, and low-grade patient allergy to the graft material. 7 Seromas have been noted after open abdominal aortic aneurysm (AAA) repair but are presumed rare [8][9][10][11][12] ; to date, less than 15 cases have been reported with the largest series consisting of 5 cases. 8 Our experience suggests an incidence significantly greater than reported in the literature.…”
