Streptococcus pneumoniae causing mycotic aneurysm in a pediatric patient with coarctation of the aorta

Lethal recurrent mycotic ascending aortic pseudoaneurysm in a 21-month-old child with repaired subaortic membrane

Mycotic pseudoaneurysm of the aorta is a rare and lethal complication of pediatric congenital heart surgery. We report the lethal consequences of recurrent mycotic pseudoaneurysm in an 18-month-old baby, early after subaortic membrane resection. We managed to repair the pseudoaneurysm successfully by replacing the infected ascending aorta using bovine jugular vein graft, but unfortunately, the patient developed new pseudoaneurysm at the site of anastomosis which led to his death. Although prompt diagnosis and surgical management can save the patient life, uncontrolled infection can lead to the recurrence of the problem and lethal results.

Successful surgical management of coarctation of the aorta with infective endaortitis and splenic abscess: a case report

Infective endaortitis with a splenic abscess is an extremely rare and fatal complication of coarctation of the aorta. We herein describe a 19-year-old female patient with a 2-month history of intermittent fever with progressive abdominal and leg pain. Aortic computed tomography angiography showed a rapidly progressive poststenotic saccular aneurysm immediately distal to the coarctation. Enhanced abdominal computed tomography showed a severe splenic abscess. During the operation, the infected spleen was resected first. We subsequently removed all of the diseased aorta and performed in situ aortic reconstruction with an artificial tube graft and without extracorporeal circulation. The patient had an uneventful postoperative clinical course and recovered very well during the 4-year follow-up. In summary, our case report details the successful surgical treatment of coarctation of the aorta with infective endaortitis and a splenic abscess and thoroughly discusses the indications and key notes for surgery without extracorporeal circulation in this complex disease.

Surgical management of ascending aortic pseudoaneurysm in a 2-year-old boy: a case report

BACKGROUND

Aortic pseudoaneurysms are rare but life-threatening complications usually seen after cardiac surgery. The causes could be multifactorial such as infection or trauma.

CASE PRESENTATION

We report the surgical management of a postoperative pseudoaneurysm of the ascending aorta caused by methicillin-resistant Staphylococcus aureus in a 2-year-old Middle Eastern boy who had undergone ventricular septal defect closure, subaortic membrane resection, and pulmonary artery de-banding. He was immediately operated on for resection of the aneurysm. A computed tomography scan at 2 months following surgery showed no aneurysm. Antibiotics were continued for 6 weeks and our patient was discharged with negative blood cultures.

CONCLUSION

Early diagnosis and appropriate treatment of such rare complication can be lifesaving.

Mycotic aneurysm in a child with history of coarctation of the aorta repair

A mycotic aneurysm is a rare condition occasionally seen in patients with a history of prior cardiac or vascular surgery. Here we report the presentation of a mycotic aneurysm in a pediatric patient at the site of prior aortic coarctation repair. This patient's initial presentation suggested rheumatologic or oncologic disease, and after diagnosis he continued to show evidence of splenic, renal and vascular injury distal to the mycotic aneurysm site while being treated with antibiotics. We discuss the diagnosis, treatment and management of this condition.

Aortoesophageal fistula and coarctation of the aorta in a 15-year-old child

Delayed presentation of coarctation of the aorta can be associated with severe complications. A challenging case of aortoenteric fistula secondary to an aneurysm from coartation of the aorta presented with massive gastrointestinal hemorrhage. The clinical management of this patient and a review of the literature are presented.
