In Japan, TIVADs are generally placed in position by the percutaneous subclavian vein puncture approach (SVPA). However, this approach causes infrequent intraoperative or postoperative complications. Using the internal jugular vein puncture approach (IJVPA), TIVADs could be placed more easily and safely. Materials and Methods: Fifty-six patients who received TIVADs for chemotherapy of colorectal carcinomas were enrolled in this study. The choice of approach (IJVPA or SVPA) was adopted at the discretion of each doctor in charge of the patient. The operation time, success rate and complications of the two approaches were compared and evaluated. Results: TIVAD placement was successful in all patients. Thirty patients received the device via IJV puncture, but 1 patient required conversion to SVPA. Twenty-six patients underwent SVPA for device placement, but 3 of these patients required conversion to IJVPA. Mean operation time was 34.3 min in IJVPA and 35.2 min in SVPA. The success rate was 96.6% in IJVPA and 88.5% in SVPA. No severe perioperative complications were observed. However, long-term complications were observed in five cases, 3 by IJVPA and 2 by SVPA, but no significant difference in the rate of complications was observed between these two approaches. A catheter-related thrombosis was found by CT scan in 3 patients, two of whom underwent IJVPA (6.7%) and one case underwent SVPA (3.8%). Two patients received simultaneous administration of bevacizumab. Catheter infections occurred in 1 patient who underwent IJVPA (3.3%) and 1 patient who underwent SVPA (3.8%). Conclusions: The IJVPA is a safe and feasible method for TIVAD placement.展开更多

Although there is debate over whether patch angioplasty or primary closure should be used to reconstruct the bifurcation after carotid endarterectomy, there is growing evidence in the literature in favor of patch angioplasty. When compared to primary closure, patch angioplasty during conventional carotid endarterectomy is suggested to lower the incidence of restenosis and recurrent ipsilateral stroke. Various materials have been used as a patch in this procedure, including the saphenous vein, synthetic patches, or less frequently, an internal jugular vein patch where extensive narrowing of the internal carotid artery is evident. In our case, we used an internal jugular vein graft after inadvertent severing the internal carotid artery (ICA) during carotid endarterectomy after the failure of reconstruction with a saphenous vein patch. We also encountered immediate postoperative reactionary hemorrhage following anesthetic reversal, necessitating an urgent re-exploration. The purpose of this case report is neither an attempt to suggest all patients need angioplasty nor to state that an internal jugular vein patch or graft is superior to synthetic material or saphenous veins;rather, it is an attempt to emphasize a potentially effective rescue way to reconstruct inadvertent extensive vascular injury during carotid endarterectomy.展开更多

The internal jugular vein or subclavian vein is the routine target. Arterial injury is not uncommon during the procedure but is potentially devastating in spite of the safety and advantages of the Seldinger technique. Compressing of the airway by a hematoma, as well as hemothorax, pseudoaneurysm, arteriovenous fistula, stroke, and even death, has been well-described.展开更多
