Central Venous Access Lines

5 million central venous access lines are placed every year in the United States, and it is a common surgical bedside procedure. We present a case of a central venous catheter placement with port for chemotherapy use, during which a duplication of a superior vena cava was discovered on CTA chest after fluoroscopy could not confirm placement of the guidewire. Due to its potential clinical implications, superior vena cava duplication must be recognized when it occurs.

Purpose The subclavian vein is thought to be the most appropriate route for central venous access in major maxillofacial surgery. Evidence suggests that left-sided central venous catheters should lie below the carina and be angulated at less than 40° to superior vena cava wall. This reduces perforation risk. With this in mind we audited our current practice for placement of central venous catheters for major maxillofacial surgery. The criteria against which we compared our practice were: 1) all catheter tips should lie below the carina and 2) the angle of the distal 1 cm of the catheter should be no more than 40° to the superior vena cava wall. Methods Left subclavian central venous catheters placed on a weekly operating list between September 2005 and August 2008 were identified retrospectively: 83 patients were identified; 22 were excluded. The angle of the central venous catheter tip and distance from the carina were measured on the first post-procedure chest-X ray. All central venous catheters used were 16 cm long. Results 82% of the catheter tips were located above the carina while 61% were angulated at greater than 40°; 11% of central venous catheters met both standards; 14% of central venous catheters placed by a consultant and 12% of catheters placed by a trainee met both standards. Conclusions 89% of the central venous catheters were not correctly placed. The majority of central venous catheter tips above the carina were at an adverse angle to the superior vena cava wall. We suggest that for left subclavian central lines, 20 cm catheters be used.

Highlights Recurrent central venous access can lead to central venous occlusions. Collateral flow can be used adventitiously for PICC tip placement. Sharp recanalization can be used to reconstitute patency of an occluded SVC.

Purpose The purpose of this study was to evaluate the efficacy of placement of tunneled hemodialysis catheters in patients with occluded or stenotic central veins. Materials and Methods Data were prospectively collected for 26 patients (11 male, 15 female, mean age 52 years) referred for placement of tunneled hemodialysis catheters with central venous stenoses or occlusions. The central venous occlusions or stenoses were recanalized using traditional interventional catheter and guidewire techniques. Results Thirty central venous access procedures were performed of which 28 (93%) procedures resulted in successful tunneled catheter insertion. Twenty-one internal jugular venous (13 right, 8 left) and 7 subclavian venous (3 right, 4 left) catheters were placed. Eighteen stenotic and 10 occluded venous segments were crossed including the brachiocephalic vein (n = 22), subclavian vein (n = 2), and the superior vena cava (4). One patient required insertion of a metallic stent to facilitate passage of the hemodialysis catheter across an occluded brachiocephalic vein. No procedure-related complications occurred. No episodes of upper extremity swelling or superior vena cava syndrome occurred following catheter insertion. Conclusion Insertion of tunneled hemodialysis catheter across occluded or stenotic central veins is technically feasible and safe. The use of occluded or stenotic central veins for catheter access preserves patent central veins for future shunt access.

AbstractParadoxical cerebral embolism, although rare, can be secondary to acquired causes such as superior vena cava (SVC) occlusion and development of a mediastinal right-to-left shunt. Such shunts allow undisturbed passage of thromboemboli to bypass the pulmonary circulation and enter the systemic circulation. This report presents a case of paradoxical cerebral embolism due to a right-to-left shunt originating from occlusion of the SVC. The etiology of the SVC occlusion stems from a prior central venous access line used for treatment of lymphoma. The patient underwent endovascular treatment with successful coil embolization of the mediastinal shunt.
