Polytetrafluoroethylene‐covered nitinol stent graft for treatment of carotid artery blowout syndrome in head and neck cancer patients

Abstract

Covered stent placement is highly feasible and proved effective without major complications in CBS due to carotid axis bleeding.

Safety and effectiveness of endovascular embolization or stent‐graft reconstruction for treatment of acute carotid blowout syndrome in patients with head and neck cancer: Case series and systematic review of observational studies

“…The MINORS quality scores ranged from 7 to 11. An overview of the characteristics of the studies is provided in Table …”

“…An overview of the characteristics of the studies is provided in Table 1. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Of the 292 patients, 26 patients did not have relevant or extractable data. Of the remaining 266 patients, 137 were treated with embolization (77 for ICA and/or CCA and 60 for ECA).…”

Endovascular Management of Post-Irradiated Carotid Blowout Syndrome

“…The indications for RE of group 2B patients were the patients at risk of permanent carotid occlusion, such as those with contralateral carotid occlusion, intolerance to a balloon occlusion test, or emergency status of the patient precluding an occlusion test [ 13 , 14 ]. The technique of RE has been described in previous studies [ 14 , 16 ]. We used a self-expandable stent-graft, including Wallgraft stent-graft (Boston Scientific Corp, Natick, Mass), Fluency stent-graft (Bard/Angiomed GmbH & Co, Karlsruhe, Germany), or Viabahn (W.L.…”

“…Various endovascular treatment algorithms have been proposed but none have been standardized [ 13 , 15 ]. Although a reconstructive method with stent-graft has been reported to be a temporary method of management, recent reported series have shown that this method can yield promising results [ 14 , 16 – 18 ]. Clinical severity has been reported to influence the rebleeding rate of patients with PCBS, but this has not widely validated [ 14 , 19 ].…”

Prediction of Borderzone Infarction by CTA in Patients Undergoing Carotid Embolization for Carotid Blowout

“…9,[16][17][18] The rates of stent-related complications, such as instent thrombosis, cerebral ischemia, and septic embolism, have been reported to approach 25%-50%, with neurologic complication rates of 10%-27.8%. 9,29 The unacceptably high poststenting complication rates could be attributable to inadequate antiplatelet therapy during clinical emergencies and contamination from the exposed artery. Therefore, we did not consider that routine stent-graft deployment was justified in patients with CBS, though it might be beneficial if both the initial CTA and confirmative BTO were considered risky for borderzone infarction.…”
