A septuagenarian man who had chronic renal failure was admitted to our hospital for vascular access formation.
He had a past history of thoracic and abdominal aortic aneurysm [Figure 1]. An arteriovenous fistula was made on his left forearm. After operation, the swelling of his forearm did not improve. A month later, he was initiated into hemodialysis therapy. After initiation, we performed vascular access angiography with suspicion of venous stenosis. [Figure 2a] is an angiography of his left subclavian vein during the phase of expiration which shows regurgitation into the cervical vein. The regurgitation occurred along with the edge of aortic aneurysm. [Figure 2b] is also an angiography during the phase of inspiration which did not show regurgitation. Aortic aneurysm sometimes causes superior vena cava (SVC) syndrome by compression of surrounding veins.[1],[2] We considered a similar phenomenon occurred partially during only the phase of expiration. The cause of only partial compression which resulted in forearm swelling was considered to be the increase of blood flow with vascular access. | Figure 1: An image of three-dimensional computed tomography which shows aortic aneurysm.

We should take this phenomenon, not only venous stenosis, into consideration when we see swollen forearm with vascular access.
