Tracheobronchial arterial variants of vertebral artery origin and bronchovertebral arterial anastomoses.
Philippe GailloudPublished in: Surgical and radiologic anatomy : SRA (2022)
This report presents a spectrum of tracheo-broncho-vertebral variations and emphasizes the role of previously described paratracheal arterial anastomoses in their formation. These variants can play a critical role during hemoptysis embolotherapy, either as an occult source of hemorrhage or as a risk factor for devastating complications.
