Aortic aneurysm in a four-year-old child with tuberous sclerosis

An Autopsy Case of Abdominal Aortic Aneurysm in a Pediatric Decedent With Tuberous Sclerosis Complex

ABSTRACT

Vascular involvement in tuberous sclerosis complex (TSC) is uncommon and even more so in pediatric patients. When asymptomatic, these vascular abnormalities carry increased risk of rupture with increased morbidity and mortality. Here, we describe a case of a ruptured unrecognized abdominal aortic aneurysm in an 11-month-old patient with a history of TSC. The abdominal aortic aneurysm was discovered at autopsy and highlights the rarity of abdominal aortic aneurysm in pediatric patients diagnosed with TSC and the importance of screening for associated aneurysmal disease in the pediatric population with TSC. Furthermore, the extensive retroperitoneal hemorrhage seen in this case also highlights a rare but potential mimic of abuse in the pediatric population.

Recurrent symptomatic aortic aneurysm in a young girl with tuberous sclerosis complex and review of the literature

An abdominal aortic aneurysm is a rare occurrence in pediatric populations. When present, it is usually associated with an underlying etiology such as a connective tissue disorder, inflammatory process, or noninflammatory medial degeneration. In the present report, we describe the case of a girl with tuberous sclerosis complex who underwent successful emergency open repair of a symptomatic infrarenal abdominal aortic aneurysm and recurrent type IV thoracoabdominal aortic aneurysm.

Abdominal aortic aneurysm in a child with tuberous sclerosis

Abdominal aortic aneurysm is rare in the pediatric population and even more uncommon in association with tuberous sclerosis. We have presented a unique case of a 3-year, 8-month-old girl who was successfully treated. She was admitted because of breakthrough seizures. A painless pulsatile abdominal mass on examination prompted an abdominal ultrasound scan, which identified a large saccular abdominal aortic aneurysm. Urgent replacement of the abdominal aorta with a 12-mm woven Dacron graft was undertaken. A postoperative ultrasound evaluation confirmed the successful repair. She was growing well when examined 7 months after surgery.

Endovascular Repair of a Descending Thoracic Aortic Aneurysm in a Pediatric Patient with Tuberous Sclerosis: A Case Report and Review of the Literature

Aortic aneurysm in children is rare, but has been described in the tuberous sclerosis complex (TSC) population. While surgical repair has been utilized as the primary means of intervention, we present the first known case reporting exclusion of a descending thoracic aortic aneurysm with percutaneous covered stent implantation in a pediatric patient with TSC. A review of the literature is also included herein.

Open Repair for Abdominal Aortic Aneurysm in a Young Boy with Tuberous Sclerosis and Review of the Literature

BACKGROUND

Abdominal aortic aneurysms (AAAs) are very rare in pediatric patients and can rarely be associated with tuberous sclerosis (TS). Open surgery is the first-line therapy. We report our experience added by a review on current literature.

CASE REPORT

A 9-year-old boy with TS and history of 2 earlier open repairs for AAA presented to our department with a recurrent juxtarenal aortic aneurysm. We performed a polytetraflourethylene patch plasty. Postoperative course was uneventful. After 8 months, reconstruction was stable, and no recurrent aneurysm developed.

CONCLUSIONS

Recurrent aneurysms may develop after open surgery for TS-associated AAA. However, open surgery is the recommended therapy but requires special techniques and experience in pediatric patients.

Anaesthetic management of children with tuberous sclerosis

BACKGROUND

Tuberous sclerosis (TS) is a hamartomatous disease that usually presents with cutaneous and intracranial lesions, but can also affect other organ systems.

METHODS

In this report, we retrospectively reviewed the perioperative course of 24 children with TS who had medically intractable seizures as the primary disease process.

RESULTS

Cardiac rhabdomyoma was detected in 11 of 18 patients who had a cardiac evaluation, and coexisting congenital heart defects were diagnosed in six. Ten of 17 patients who had a renal evaluation were diagnosed with renal TS, presenting with azotaemia in one and hypertension in four. The major perioperative complications in the 52 anaesthetics, included death (a neonate after cardiac rhabdomyoma resection), seizures (five patients) and bradyarrhythmias (two patients).

CONCLUSIONS

Patients with TS and neurological disorders frequently have coexisting cardiac and renal disease as well. Patients with TS should be evaluated for these organ specific disorders prior to surgery.

Aortic aneurysms in children and young adults with tuberous sclerosis: report of two cases and review of the literature

Abdominal aortic aneurysms (AAAs) in children and young adults are rare; some have been observed in patients with tuberous sclerosis (TS). We report two cases and review the literature. A 9-year-old girl with TS was diagnosed with a 3-cm calcified AAA, and a 41-year-old man with TS was diagnosed with a 7.5-cm thoracic aortic aneurysm (TAA). Both patients underwent open repair with a tube polyester graft without complication. They are both doing well at 7 and 8 years after surgery. Pathologic evaluation revealed medial atrophy and focal medial disruption in the aortic wall in both patients. With our two cases, 15 patients with TS and aneurysms have been reported; 12 had AAA, and four had TAA (one patient had both). Three AAAs and two TAAs ruptured. Six patients died because of aneurysmal disease. There is an association between TS and aortic aneurysms. Patients should be screened for aortic aneurysms at the time TS is diagnosed and annually thereafter. Because of the high risk of rupture, early elective repair is suggested. New aortic aneurysms after repair may also develop.
