Pulmonary arteriovenous fistula in childhood
Insights
Pulmonary arteriovenous fistulas are more severe in children and require prompt surgical intervention. Early surgical treatment is recommended, even for asymptomatic cases, to prevent complications.
Area of Science:
- Cardiology
- Pediatric Surgery
- Diagnostic Imaging
Background:
- Pulmonary arteriovenous fistulas (PAVF) are congenital vascular malformations.
- PAVF can present with significant morbidity, particularly in pediatric patients.
- Early diagnosis and intervention are crucial for managing pediatric PAVF.
Observation:
- Two pediatric cases of PAVF treated at the University Clinic of Mainz are presented.
- Childhood PAVF often exhibits diffuse angiodysplasia with pronounced clinical signs.
- Non-invasive diagnostic techniques are recommended for initial evaluation.
Findings:
- Complications associated with PAVF can occur even in asymptomatic children.
- Surgical intervention is recommended for pediatric PAVF.
- For peripheral lesions, local excision without lung tissue removal is preferred over segmentectomy or lobectomy.
- Therapeutic embolization is a viable option for inoperable cases.
Implications:
- Prompt surgical management of pediatric PAVF is essential to prevent complications.
- Minimally invasive surgical techniques should be prioritized for peripheral PAVF.
- Embolization offers a less invasive alternative for unresectable PAVF.
- Further research into optimal management strategies for pediatric PAVF is warranted.
Abstract:
We report two cases of children with pulmonary arteriovenous fistula treated at the University Clinic of Mainz. This angiodysplasia is relatively more diffuse and the clinical signs are more marked in childhood. The non-invasive techniques should be preferred for diagnosis. Complications occur frequently even in asymptomatic children so it is recommended to operate them. The local excision without extirpation of lung tissue should be preferred to segmentectomy or lobectomy for peripheral lesions. Therapeutic embolisation should be tried in inoperable cases.
