The long-term effects of hemodialysis arteriovenous fistula (AVF) closure on left ventricular (LV) morphology are unknown. Using echocardiography, we prospectively studied 17 kidney transplant recipients before, 1, and, 21 months after AVF closure (mean fistula flow 1371 +/- 727 mL/min). Eight kidney transplant recipients with a patent AVF, matched for age, time after AVF creation, and time aft...

Local complications of femoral arterial catheterization like hematomas, pseudoaneurysm (PSA) and arteriovenous fistula (AVF) are increasing in incidence due to the large number of patients undergoing diagnostic and therapeutic angiographic procedures through this route [1 3] (see figure 1). A PSA refers to a confined collection of thrombus and blood associated with tear of one or more layers of...

Subacute necrotizing myelopathy (SNM) or Foix-Alajouanine syndrome is a rare disease characterized by progressive neurological dysfunction caused by a spinal dural arteriovenous fistula (AVF). Radiological diagnosis is usually suspected when there is intramedullary nonspecific enhancement and perimedullary flow voids. Ring-enhancement is rarely reported in the scope of AVF, which poses a diagno...

Traumatic AVF of the scalp is a rare abnormal vascular disease. It is defined as a communication between the high flow arterial system and the low flow venous network, which directly connects the arterial feeding vessels of the scalp and the draining veins without an intervening capillary bed. The superficial temporal artery (STA) was involved in 90% of the cases, and 71% of the patients only h...

Traumatic arteriovenous fistulas (AVFs) are rare, including the scalp, carotid cavernous sinus, vertebral artery and ophthalmic artery. AVF of the scalp is direct connections between the arterial feeding vessels of the scalp and the draining veins without intervening capillary beds. The draining veins are often grossly enlarged and tortuous, like a varix. We experienced a rare case of traumatic...

We describe the imaging findings in a dural arteriovenous fistula (AVF) with unilateral subcortical calcification. A 50-year-old woman patient suffered from hypertension and chronic headache. Recently, marked headache and a changed consciousness level were noted. The imaging studies demonstrated left subcortical calcification and cerebral sulcus effacement. MR imaging and angiography revealed m...

PURPOSE Arteriovenous fistula non-maturation because of a peri-anastomotic venous stenosis is currently a huge clinical problem for which there are no effective therapies. METHODS In an attempt to further define the cellular pathways involved in this process we have assessed the pattern and intensity of macrophage infiltration at different time points in a pig model of AVF stenosis. RESULTS...

Focal segmental glomerulosclerosis (FSGS) is a leading cause of end-stage renal disease and has a high recurrence rate after kidney transplantation, attributed to a circulating permeability factor. Plasmapheresis is the treatment of choice after recurrence to remove the circulating factor. We present a case of recurrent FSGS 6 years after transplantation. It is instructive because proteinuria d...

Flows (Qa) of arteriovenous fistula (AVF) impact the dialysis adequacy in hemodialysis (HD) patients. However, data for different access flow levels on outcomes related to long-term dialysis patients, especially in Chinese patients, are limited. Herein, we performed an ambispective, mono-centric cohort study investigating the association between the AVF flows and inflammation, cardiovascular ev...

Abstract The main type of access used for hemodialysis is the arteriovenous fistula (AVF) because it offers superior patency and lower complication rates when compared to other accesses. We report case a 69-year-old female patient with chronic kidney disease on dialysis secondary hypertensive nephrosclerosis radiocephalic AVF in left upper limb created 9 years previously. Two previously, she ha...
