Surviving the Nightmare: Massive Bleeding From Large Intraoral Arteriovenous Malformation During Airway Management for Angioembolization Procedure.
Case Rep Anesthesiol
December 2024
Department of Anaesthesiology, Aga Khan University Hospital, Karachi, Pakistan.
Arteriovenous malformations (AVMs) in the head and neck present significant challenges due to airway management complexities and hemorrhage risks. This case report describes a 15-year-old female with a congenital facial AVM causing dyspnea and obstructive symptoms. The patient required angioembolization of the AVM, but many hospitals deferred the procedure due to the anticipated difficult airway and severe bleeding risks.

Arteriovenous malformation (AVM) of the head and neck, though rare, can present significant clinical challenges, particularly during dental procedures. This case report details the acute management of a 7-year-old girl with an AVM in the right mandible, with sudden, severe, torrential intraoral hemorrhage during an angioembolization procedure, necessitating immediate airway management and hemodynamic stabilization in a nonoperating room anesthesia (NORA) setting. Persistent bleeding led to a multidisciplinary intervention, including external carotid artery ligation and right hemimandibulectomy, achieving hemostasis.

Article Synopsis
- Anastomoses between pulmonary arteries and veins, which are common in adults, can lead to blood bypassing alveoli, causing hypoxaemia, especially in conditions like COVID-19 and influenza A.
- A case of severe hypoxaemia linked to influenza A was poorly responsive to oxygen treatment and worsened with CPAP, indicating a significant intrapulmonary shunt contributing to the issue.
- Understanding these shunts in viral infections can improve respiratory treatment strategies and help identify new therapeutic approaches to prevent the need for intubation.
Tracheal airway obstruction induced by a large glomangioma: discussion of management and literature review.
BMJ Case Rep
September 2024
Otorhinolaryngology, Head and Neck Surgery, Hospital of Sion, Sion, Switzerland.
Article Synopsis
- * An 80-year-old Caucasian man experienced upper airway obstruction and significant bleeding due to a large tracheal glomus tumor, which was diagnosed as glomangioma.
- * GTs comprise about 1.6% of soft tissue tumors, with tracheal cases posing the greatest risk of malignancy and potential airway obstruction; diagnosis is confirmed through histological analysis, and surgical resection is the main treatment.
Congenital Lung Malformations: A Pictorial Review of Imaging Findings and a Practical Guide for Diagnosis.

The term congenital lung malformation (CLM) is used to describe a wide range of pathological conditions with different imaging and clinical manifestations. These anomalies stem from abnormal embryological lung development, potentially occurring across various stages of prenatal life. Their natural history can be variable, presenting in a wide range of severity levels and encompassing asymptomatic individuals who remain so until adulthood, as well as those who experience respiratory distress in the neonatal period.
