He was bleeding massively from the right neck wound and oral cavity. Cervical angiography showed bleeding from the right external carotid artery and intimal injury to the right internal carotid artery. Balloon occlusion at the common carotid artery origin and distal to the injured internal carotid artery controlled active bleeding. During vascular balloon occlusion, definitive hemostatic treatment was achieved through ligation of the proximal external carotid artery.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Neck exploration combined with endovascular treatment may be one option as a treatment strategy for patients with zone II penetrating neck injury.</p>\u0000 </section>\u0000 </div>","PeriodicalId":7196,"journal":{"name":"Acute Medicine & Surgery","volume":"11 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ams2.70022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
