During surgical reconstruction of AVGs, surgeons may be required to manage previously implanted stent grafts. We report a case of AVG reconstruction using the transected end of a pre-existing stent graft as the venous anastomosis. A 78-year-old woman undergoing long-term hemodialysis developed graft degeneration with recurrent stenosis despite a functioning stent graft in the venous outflow. Because creation of a new vascular access on the other arm was not feasible, ipsilateral reconstruction was performed. A new prosthetic graft was anastomosed to the radial artery arising from a high bifurcation of the brachial artery at the distal upper arm, near the elbow. On the venous side, the prosthetic graft overlapping the stent graft was completely excised, and the stent graft was transected at a segment not overlapped by the prosthetic graft within the native vein. End-to-end anastomosis was then created between the new prosthetic graft and the transected stent graft. Postoperative angiography confirmed good patency of the anastomosis and venous outflow, and access flow improved significantly. The reconstructed AVG was suitable for cannulation 10 days after surgery.

Additionally, PICCs offer a safer option than peripheral access for the infusion of vesicants, irritants, hyperosmolar solutions, antibiotics, prolonged parenteral nutrition, and chemotherapy agents. We present a case of perforation of the internal jugular vein caused by PICC migration in the early postoperative days following neck dissection and free flap reconstruction. During surgical exploration, a large cervical hematoma was evacuated. Bleeding was traced to multiple lacerations of the internal jugular vein, the largest measuring 15 mm. The venous anastomosis of the radial forearm free flap was intact. The internal jugular vein was temporarily clamped, repaired with sutures, and the PICC was removed intraoperatively. Despite the lacerations being caudal to the anastomosis, the free flap was preserved, and the patient was discharged without further complications. An increase in thoracic pressure, such as that resulting from a forceful cough or vomiting, can lead to the displacement of PICC lines. In patients who have undergone neck dissection, episodes of vomiting or severe coughing should be carefully monitored for the risk of PICC tip migration. This migration could cause simultaneous laceration of the vessel wall, leading to potentially life-threatening hematomas. Monitoring the tip position of PICCs in this type of patient could be performed at the bedside at least weekly during scheduled dressing changes and/or sutureless system changes. In this way, secondary malpositions of the tip could be identified early and potentially life-threatening complications such as those in this report could be avoided.</p>","PeriodicalId":56113,"journal":{"name":"Journal of Vascular Access","volume":" ","pages":"11297298261443389"},"PeriodicalIF":1.7,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147823737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
