Event Description

The following literature article was reviewed: frequency of perigraft hygroma after open aortic reconstruction.Background perigraft hygroma (pgh) is a persistent collection of sterile fluid around a prosthetic vascular graft.The incidence of pgh development after aortic reconstruction remains poorly defined and its clinical relevance is questionable.Most pghs are asymptomatic and do not require surgical intervention.However, with expansion these fluid collections can present symptoms of abdominal pain, vomiting, and, in worst cases, graft compression with thrombosis or rupture of the pgh sac.This study was designed to establish the incidence of and determine the risk factors associated with pgh formation and its outcomes.Patients and methods patients who underwent open aortic reconstruction for either aneurysmal or occlusive disease with an expanded polytetrafluoroethylene (eptfe) or polyester graft from 2004 to 2018 were retrospectively reviewed (n=262).Only those who had follow-up imaging 3 or more months after repair were included.Patients with mixed graft types were excluded.Pgh was defined as a perigraft fluid collection of 30 mm or greater in diameter with a radiodensity of 30 or fewer hounsfield units on computed tomography at a minimum of 3 postoperative months.Analysis was conducted between patients with and without pgh.Results one hundred forty patients met the inclusion criteria: 88 were treated with eptfe (all manufactured by w.L.Gore & associates) and 52 with polyester grafts.Twenty-three patients (16.4%) were found to have radiologic evidence of pgh.Pgh developed more frequently in patients with eptfe (21/88 [23.9%]) compared with those with polyester grafts (2/52 [3.8%]) (p=.002).One patient presented with abdominal pain related to the pgh at 52 postoperative months.A ct-guided percutaneous drainage of 350ml of periaortic fluid from the 11.9 cm pgh was performed 2 days later.The drainage immediately relieved his symptoms, but ultimately the fluid reaccumulated to an 11.6 cm hygroma 3 months later.At that point, he was still asymptomatic, but underwent prophylactic marsupialization of the sac.Unfortunately, this subsequently recurred to a 15.3-cm sac before he died of aspiration while in hospital at 13.7 postoperative years.
