Summary
Arteriovenous malformations (AVMs) in the mandible are rare vascular tumors. This case study details the successful management of a mandibular AVM in a pregnant woman during her third trimester.
Area of Science:
- Vascular Surgery
- Oral and Maxillofacial Surgery
- Obstetrics
Background:
- Benign vascular lesions, including arteriovenous malformations (AVMs), can occur in various organs, but are rare in the mandible.
- Mandibular AVMs are uncommon and can present with symptoms like pain and bleeding.
Observation:
- A 35-week pregnant woman presented with right-sided jaw pain and a pulsatile mass on the internal mandible.
- The lesion caused profuse bleeding, necessitating emergent selective arterial embolization.
Findings:
- Selective arterial embolization successfully occluded the vessels of the mandibular AVM.
- Pathology confirmed the diagnosis of an arteriovenous malformation.
- The patient underwent uncomplicated vaginal delivery and subsequent surgical excision and reconstruction.
Implications:
- Mandibular AVMs can be successfully managed during pregnancy with timely diagnosis and intervention.
- The role of pregnancy-related hormonal and vascular changes in AVM exacerbation remains a subject for further investigation.
