A 47-year-old woman with stage IV chronic kidney disease developed a fistula between common carotid artery (CCA) and internal jugular vein (IJV) during central catheterization of the right IJV. The patient was treated with a self-expandable graft stent, which achieved successful closure of the carotid-jugular fistula. As demonstrated in our case, self-expandable graft stents could be a feasible treatment option for CCA-IJV fistulas without additional interventional procedures such as balloon angioplasty.

Objective: Injuries of upper cervical spine are potentially fatal. Thus, appropriate diagnosis and treatment is essential. In our institute, preoperative computed tomography angiography (CTA) has been performed for evaluation of injuries of bony and vascular structure. The authors confirmed the engorged venous plexus within injured posterior neck muscle. We have this research to clarify the relationship between the engorged venous plexus and engorged vein. Methods: A retrospective review identified 23 adult patients who underwent 23 posterior cervical spine surgeries for treatment of upper cervical injury between 2013 and 2015. Preoperative CTA was used to identify of venous engorgement within posterior neck muscle. The male to female ratio was 18:5 and the mean age was 53.5 years (range, 25-78 years). Presence of venous engorgement and estimated blood loss (EBL) were analyzed retrospectively. Results: The EBL of group with venous engorgement was 454.55 mL. The EBL of group without venous engorgement was 291.67 mL. The EBL of group with venous engorgement was larger than control group in significant. Conclusion: The presence of engorged venous plexus is important factor of intraoperative bleeding. Preoperative CTA for identifying of presence of engorged venous plexus and fine operative techniques is important to decrease of blood loss during posterior cervical spine surgery.
