Optical Coherence Tomography Characterization of Macular Changes Secondary to Arteriovenous Fistula
2017
Arteriovenous fistulas (AVFs) are abnormal shunts between the arterial and venous vascular systems. These usually produce ocular pain, increased intraocular pressure (IOP), and diplopia. Less frequently, they may cause retinal changes with visual impairment. Our purpose is to illustrate different retinal manifestations of AVF. We report the multimodal imaging study of three cases with retinal changes due to AVF, showing neurosensory retinal detachment, macular oedema, and macular ischemia. In conclusion, AVF may appear with different ophthalmic alterations. While usually increased IOP and diplopia are our main concerns, retinal study is mandatory, since a myriad of morphologic abnormalities…
Video-assisted two-stage basilic vein transposition for creation of brachio-basilic arteriovenous fistulae
2012
We report our experience in a mixed minimally-in- vasive technique for the two-stage transposition of basilic vein on a small series of eight patients. The operative tech- nique consisted of a modified endoscopic (1) approach for the two-stage transposition (2). The intervention was performed under Brachial Plexus Block (3).
The use of a new kind of low profile retractor for arteriovenous fistula procedure simplifies and speeds up the intervention
2009
Purpose The aim of this study was to demonstrate the effectiveness of a new kind of disposable surgical retractor in arteriovenous fistula (AVF) procedures in order to achieve an easier, faster and safer surgical intervention. Methods Between January and June 2008, 22 AVF procedures were performed using the 3PAWS ReeTrakttrade; (Insightra Inc. - Irvine, Ca., USA) a self-retaining, low profile retractor. An equivalent patient sample, in which an AVF was performed using conventional retraction devices, was considered for comparison of the intra- and post-operative results. Results In all of the 22 AVF procedures performed, the ReeTrakt™ system has simplified the performance of the surgical te…
Traumatic arteriovenous fistula as consequence of TMJ arthroscopic surgery. A case report
2016
The ocurrence of a traumatic arteriovenous fistula after arthroscopic surgery of TMJ represents an extremely rare event. Specifically, this uncommon complication has been described only in a few case reports. In this light, the most frequent symptoms showed by this disease are thrills, bruits, pulsatile tinnitus, and an expansible vascular mass. Importantly, the severity of these symptoms is also dependent on the vessels involved. With regard to the management, is important to note that the vessel ligation with surgery as well as vessel emolization with endovascular procedures have been shown to be effective in the treatment of these cases. In view of that, the present study describes a cas…
Arteriovenous fistula of the vertebral artery in a female infant with hypotonia and cephalocorporal disproportion
2010
Background: Congenital arteriovenous fistulas are exceptional in childhood and imply a therapeutic challenge. Case report: A 9-month-old female infant was studied for cephalocorporal disproportion, hypotonia, progressive muscular atrophy and hyperreflexia. Computed tomography of the brain and electroencephalography were normal. Electromyographic patterns suggested proximal myopathic involvement. A continuous murmur with systolic reinforcement was audible in the neck. Angioresonance detected intracranial aneurysmal dilatations behind the bulbo-medullary junction and cerebral panangiography evidenced a direct vertebrovertebral fistula with extra- and intra-cranial varices and extreme medulla…

Case report of a large cephalic vein aneurysm inducing heart failure in a renal transplant patient with radio-cephalic fistula for haemodialysis
2020
Highlights • The venous aneurysm is one of the most common complications of autologous AVF. • The vein aneurysm should be treat by surgical resection and anastomotic ligature. • AVF shouldn’t be ligated from 1-year kidney transplantation except in some cases. • Surgical ligation to prevent complications could be considered an option.
“Magnifying glass” for difficult radiocephalic arteriovenous fistulas
2012
Background: Some uremic patients suffering from diabetes, atherosclerosis or simple by absent or exhausted peripheral vascular bed require bigger effort in creating arteriovenous fistula. Although it is possible to use prosthetic graft for difficult cases, the use of native vessels falls always in the respect of patient’s quality of life. A help for these cases comes from the use of a microsurgical technique for creating vascular access. Patient and Methods: For this study we evaluated the 72 patients underwent microsurgical radiocephalic fistula comparing them to a homogeneous group of 72 patients underwent traditional surgery. The patients were followed up at 1, 2 months and 1 year. Resul…
Prone Position Facilitates Creation of Ulnar-Basilic Arteriovenous Fistula
2022
Background: The distal ulnar-basilic arteriovenous fistula (UBAVF) is a rarely used alternative type of vascular access for haemodialysis. The location of the vein on the back aspect of the forearm forces an extremely uncomfortable external rotation of the upper limb during surgery when the patient is in a supine position. Methods: We present a new approach towards creating UBAVF, which involves placing the patient in the prone position, thus eliminating the aforementioned inconvenience. The procedure was performed and described in a 46-year-old patient with chronic kidney disease (CKD) due to diabetic nephropathy. In the period from September 2021 to December 2021, we created an additional…
