Methods: We conducted a retrospective review of total 163 lung cancer patients who underwent implantations of a central venous access port for chemotherapy. 95 patients received the ports by the femoral vein blind-puncture technique and 68patients had the port implanted via the subclavian vein blind-puncture technique. The initial success rate of port implantation and the frequency of occurrence of complications were calculated. Results: The primary success rate of venous port implantation was 93.7% for femoral approach and 88.2% for the subclavian approach respectively (p < 0.05). Intraoperative complications developed in two patients (2.1%) in the femoral approach group and in five patients (7.4%) in the subclavian approach group. Although a higher intraoperative complication ratio for the subclavian approach was encountered compared to that for the femoral vein approach, there was no statistically significant difference (p = 0.103). Nor was there any statistically significant difference in terms of the occurrence of late complications. Conclusions: Venous access port implantation via the femoral vein approach is safe, and its success rate is very high, with the equal complication rates comparable to the subclavian approach. This approach avoids many of the intraoperative complications. Thus, the femoral vein approach for implanting a venous access port in lung cancer patients should be considered a valid, and safe technique.展开更多

This case report presents the case of a 94-year-old man with an iatrogenic right SCA injury resulting from a misplaced CVC. Computed tomography revealed the catheter piercing the right internal jugular vein to enter the right SCA and then reaching the aortic arch. Emergent endovascular treatment was performed, and a 13-mm × 50-mm self-expanding Viabahn stent graft (W.L. Gore & Associates, Flagstaff, AZ, USA) was placed via the right brachial artery. The misplaced catheter was successfully removed under simultaneous postdeployment balloon dilatation. This case highlights the utility of the Viabahn stent graft for iatrogenic right SCA injury caused by a misplaced CVC and presents some insights and tips for a safer procedure.展开更多
