We report a 66-year-old male patient with severe right lower extremity swelling resulting from diffuse pelvic mass with compression on right external iliac vein. The patient had papillary urothelial carcinoma of bladder seven years ago and radical cystectomy and ureterostomy was performed. Recurrence of malignancy had occurred five years after the operation. The patient had also bilateral diffuse lung metastasis. The external iliac vein had severe stenosis and invasion of pelvic mass into the vein was evident on venography. Venoplasty of external iliac vein was performed throughout the stenosis. A venous stent of 80 mm length and 12 mm diameter was introduced over the guidewire and deployed in the external iliac vein. Dramatic clinical response was evident since postoperative day two. Swelling of right lower extremity was resolved dramatically on three-month and six-month follow-up visits. We believe that endovascular venous recanalization of iliac veins is feasible and safe in patients with unresectable and diffuse pelvic masses.
We report a case of 66-year-old woman with true aneurysm of the right brachial artery. She presented with acute upper extremity ischemia. The hand was cold and parenthesized and distal pulses were absent. CT angiography (CTA) revealed a 20*25 mm true brachial artery aneurysm. The aneurysm was thrombosed without distal run-off. We excised the aneurysm and reestablished the arterial flow by a reverse saphenous interposition graft. The postoperative course was uneventful.
main body by 20cm in the DB model. Accordingly, the iliac limbs of the DB model presented a 9mm stenosis over a 30mm-segmental length in the mid-portion of the limbs. The displacement forces were estimated during a cardiac cycle at three segments (main-body, bifurcation and iliac limbs) of both models with Computational Fluid Dynamics analysis. Results-The DB accommodation was associated with higher forces at the main-body (range 3.15-4.9N) compared to the classic configuration (1.56-2.34N). On the contrary, the forces at the bifurcation (3.81-5.98N vs. 3.76-5.54N) as well as at the iliac limbs (0.34-0.85N vs. 0.49-0.74N) were comparable for both models (Figure 1). Conclusion-The DB accommodation seems to correlate with higher displacement forces at the main-body of aortic endografts compared to the classic bifurcated design. Consequently, regular imaging follow-up of the DB design deems necessary to delineate its mid-and long-term hemodynamic and clinical performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
