Abstract:
Objective:To summarise and analyse the experience in the diagnosis and management of abdominal aortic endograft infection in recent years.Methods:Retrospectively summarised and analysed the general data, clinical presentation, laboratory and imaging findings, causative organisms and treatment choices of 14 patients with abdominal aortic endograft infection treated in Beijing Friendship Hospital, Capital Medical University, from January 2018 to June 2024, and analysed the prognosis of the patients and the risk factors associated with prognosis.Results:Positive bacterial cultures were 10 out of 14 patients. One non-operatively treated patient died of infectious toxic shock. Thirteen surgically treated patients underwent axillary-bifemoral artery bypass, removal of the infected stent, and closure of the aortic stump. Four of the 13 cases had combined aortoenteric fistula, 3 cases underwent one-stage enterocutaneous fistula repair, 1 case only fistula drainage, 3 cases of gastrojejunal anastomosis, all of them underwent gastric or jejunal nutrient tube implantation. Two of the 13 patients had combined the infection foci spread to the renal artery openings. To save the kidney, intraoperative left kidney autologous renal transplantation was performed in 1 case, and autologous saphenous vein reconstruction from celiac trunk artery-left renal artery and superior mesenteric artery-right renal artery was performed in the other case. All 14 patients were retrospectively summarised and followed up in August 2024, with 5 deaths in the early postoperative period (< 3 months), 3 deaths in the mid- to long-term period (≥3 months), and 5 survivors, with a median follow-up time of 2 years (1-5 years) for surviving patients. Among the 13 operated patients, 4 cases were combined with aortoenteric fistula, and 3 cases died in the early postoperative period; 4 cases of abdominal aortic infection foci involving renal artery openings, 2 cases of early postoperative death; 4 cases with pleural effusion, 4 cases died in the early postoperative period; 2 cases of combined creatinine elevation, 2 cases of early postoperative death; 2 cases of postoperative infection of artificial blood vessels.Conclusions:Abdominal aortic endograft infection are aggressive. The risk of early death is increased in patients who are elderly, in poor general condition, with aortoenteric fistula or with pre-existing cardiac, pulmonary, hepatic and renal insufficiency, but surgery based on adequate anti-infective therapy remains an effective means of saving the patient′s life.
