A mouse model of stenosis distal to an arteriovenous fistula recapitulates human central venous stenosis

Highlights Dialysis patients with arteriovenous fistula who have central venous stenosis develop collateral veins in the axilla and chest wall. These veins are at risk of spontaneous rupture, and major bleeding may occur. Bleeding should be controlled immediately by using a compression bandage, and patients should be resuscitated with fluids and blood transfusion before surgical ligation of the bleeder. Awareness of this complication and early protection can save the patient from life-threatening hemorrhage.

Introduction: Many causes leads to kidney impairment. This does not rule out the increasing number of patients undergoing hemodialysis. The common vascular access used during hemodialysis is an arteriovenous fistula (AVF). The arteriovenous fistula was preferred because it lasts longer and has a lower risk of infection for vascular access, meanwhile central venous stenosis or occlusion in the vein that carries the blood from the extremities to the heart often occur. If vascular access is still used during hemodialysis in which central venous stenosis is formed, it needs to make a new vascular access option. Percutaneous transluminal angiography (PTA) main objectives are to dilate the venous lesion that has occlusion more than 50% and extending the lifespan of arteriovenous fistula. In this case, we report six patients hemodialysis with central venous stenosis treated with percutaneous transluminal angiography. This procedure has benefits that are arteriovenous fistula can be used again to reach hemodialysis adequacy optimally and reduce pain and swelling in the arms. Case description: There six cases who were 45,48,57.58,63 and 66 years old who underwent percutaneous transluminal angioplasty procedures for central venous stenosis. Several past illnesses of the patients underlying the kidney impairment such chronic hypertension, chronic coronary heart complications, and/or diabetes. Several patients felt AVF swollen and/or painful. Minimal residual stenosis after balloon angioplasty was performed. Conclusion: According to our cases, patients that underwent the hemodialysis felt swollen or/and pain due to stenosis ballooning angioplasty help minimize the residual stenosis.
