In such cases, intervention is unindicated for these asymptomatic lesions or those with minimal associated symptoms [110]. Of note, it is common for a degree of arm edema to occur in patients after AV access construction, possibly related to operative trauma and/or mild venous hypertension. Its postoperative resolution usually occurs in 2 to 6 weeks as the peri-surgical inflammation subsides, and venous collaterals develop. US Duplex Doppler Hemodialysis Access Area of Interest CDUS represents a noninvasive method to evaluate CVS. Limitations include its inadequate use when used to conduct central venous assessments in the absence of an angiographic map. The subclavian and brachiocephalic veins, as well as the SVC are located deep and are thus routinely difficult to visualize on CDUS [17]. Given the limitations of US in reliably assessing the culprit lesion in the thoracic cavity, there is no relevant literature to Dialysis Fistula Malfunction support the use of duplex Doppler US of the hemodialysis access in evaluation of a suspected CVS or occlusion, suggested by swelling of the extremity ipsilateral to the hemodialysis access. Variant 9: Abnormal skin changes associated with the upper or lower extremity hemodialysis access cannulation site, including marked thinning, ulceration, eschar formation, spontaneous bleeding, pseudoaneurysm formation, superficial or deep infection. Initial imaging to guide interventional radiologic therapy options. Fluoroscopy Fistulography Hemodialysis Access Area of Interest In the absence of vascular access site infection, fluoroscopic fistulography of the hemodialysis access may have been considered as an option prior to surgical repair of an aneurysm or pseudoaneurysm to evaluate and treat an underlying venous outflow stenosis that may be a precipitator of the associated aneurysm or pseudoaneurysm [123].
