1 Patients with head and neck cancers and associated postirradiated carotid blowout syndrome: Endovascular therapeutic methods and outcomes  Feng-Chi Chang, MD, Jiing-Feng Lirng, MD, Chao-Bao Luo, MD, Shuu-Jiun Wang, MD, Hsiu-Mei Wu, MD, Wan-Yuo Guo, MD, PhD, Michael Mu Huo Teng, MD, Cheng-Yen Chang, MD  Journal of Vascular Surgery  Volume 47, Issue 5, Pages (May 2008) DOI: /j.jvs Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 A, Left carotid angiogram in patient 10 of the reconstructive group showed only slight stenosis in the common carotid artery (grade 0, arrow). B, Contrast-enhanced axial computed tomography (CT) of the neck revealed a necrotic sinus tract (arrowheads) close to the left common carotid artery (arrow). C, Reconstructive CT angiography (curved multiplanar reformatted images) of the left carotid artery 1 month later showed patency of the stent grafts. D, Four months later, obvious distal marginal stenosis was noted (arrowheads). Large area of soft tissue necrosis and ulceration (arrows) surrounding the stent grafts caused “floating” of left carotid artery (long arrows).

3 Fig 2 A, Right carotid angiograms in patient 8 of the deconstructive group showed a ruptured internal carotid artery with active extravasation (grade 3, arrows). B, Cross occlusion was performed with deployment of two balloons distal and proximal to the pathologic lesions (arrows). A mixture of liquid adhesives was injected in the internal carotid artery between the 2 balloons (arrowheads).
