Abstract The authors report a case of iatrogenic brachial arteriovenous fistula (AVF) on the left arm in a 20-year-old man with a history of autosomal dominant polycystic kidney and failing kidney transplant. An attempt to create vascular access for hemodialysis by utilization of an existing iatrogenic brachial AVF was undertaken. The patient underwent surgical superficialization of a concomitant enlarged and deeply located vein. Four weeks after the procedure, the AVF was successfully cannulated for hemodialysis. In this case, iatrogenic/congenital AVF was successfully converted to vascular access for hemodialysis. Key words: Iatrogenic, congenital, fistula, brachial, superficialization, hemodialysis

Case Reports

INTRODUCTION Arteriovenous fistula (AVF) is defined as communication between the arterial and venous systems and is widely created as vascular access for hemodialysis. It is rarely found as congenital or acquired.1 Iatrogenic injuries are responsible for 0.02% to 13% of AVFs observed in the normal population.2,3 These are usually secondary to invasive diagnostic or therapeutic procedures, such as percutaneous cardiac catheterization (e.g., transradial, transfemoral arteriography), but there is little information regarding this complication by puncture, which is routinely performed, possibly due to hesitation in reporting it.1,2,4 Congenital vascular abnormalities, which are more frequent in autosomal dominant polycystic kidney disease (ADPKD), may additionally contribute to difficulties in vascular access creation.5

CASE REPORT We report on a 20-year-old man with a history of ADPKD and renal replacement therapy for 7 years. He was admitted to the nephrology ward due to a failing 5-year kidney transplant, probably because of immunosuppressive regimen noncompliance. The biopsy proven graft rejection was resistant to antirejection treatment. Medical anamnesis revealed no trauma in the past, but some vascular anomaly on the left upper arm was found at the age of 6 years. Finally, we decided to prepare him for hemodialysis, so vascular access was required. Peritoneal dialysis was not considered because that modality was ineffective in the past (at the age of 15 years), when dialysis-related peritonitis developed and he was switched at that time to a hemodialysis program. Due to the lack of suitable veins on both upper extremities for AVF creation and an asymptomatic “vascular anomaly” on the left arm, the cuffed catheter inserted into the right jugular vein served as vascular access for hemodialysis until kidney transplantation in 2007. Physical examination focused on vasculature revealed a pronounced pulse (70 beats per minute) on both radial and ulnar arteries bilaterally, and lack of a patent cephalic vein in the forearm. Palpation of the left arm revealed generalized pulsation. Moreover, a trill above the cubital fossa was found. There were no clinical or ultrasound features of low cardiac output. Further imaging diagnostics were employed. Duplex scan (Doppler ultrasonography), venogram, and computed tomography (CT) angiography allowed for the diagnosis of a brachial artery-to-brachial vein fistula. A

selective angiogram (Figure 1) illustrated the actual fistula. The oblique communicating channel between the brachial artery and the brachial vein was mapped near the cubital fossa, 5 cm proximal to the bifurcation of the brachial artery. On color Doppler examination, the vena comitans was found as a characteristic “mosaic” pattern (turbulent flow; Supporting Information Figure S1). A lower resistance waveform was found in the communicating artery and arterialized flow through the markedly enlarged communicating vein respectively. The blood outflow was observed by enlarged deep veins as well as by the basilic vein and further wide subclavian and patent superior vena cava. The left cephalic vein was narrowed but patent. With cardiology evaluation and an echocardiogram, no compromise of the cardiovascular system as a consequence of the fistula was observed. The patient underwent surgical superficialization of the concomitant enlarged vein as described by Weyde et al.,6,7 used for deeply located arterialized vein. The procedure was undertaken by a vascular surgeon in general anesthesia. Four weeks after the procedure, the AVF was successfully cannulated for hemodialysis with a single needle. Doppler ultrasonography showed AVF blood flow of 1292 mL/min, and brachial artery diameter of 6.1 mm and 4 mm at the precommunicating and postcommunicating channel sections respectively. The vein transposed

underneath the skin was 7 mm in diameter during ultrasound measurement (Supporting Information Figure S2). Air plethysmography as well as photoplethysmography on the fingers (PVL, Biomedix, MN, USA) performed preoperatively and postoperatively showed no ischemia up to the level of the fingers on both extremities. The follow-up since fistula superficialization has reached 18 months, without any complications related to AVF. Hemodialysis is performed three times a week for 4 hours, with two needles inserted into the elevated vessel resulting in effective blood flow of 340 mL/min–360 mL/ min in the machine (Figure 2). Hemodialysis program without any complication is fully acceptable by the patient.

DISCUSSION Congenital or acquired AVFs often remain asymptomatic for many years, as in the present case. The congenital communication between the brachial vein and the brachial artery is an extremely rare vascular malformation. In one of the reports, such fistulas on both sides of a 54-yearold male cadaver who died of road traffic accident were described. There was a communication (1.5 cm in length) between the brachial artery and the brachial vein, 11.5 cm above the medial epicondyle.8 Iatrogenic origin of AVF is most probable in our case, but a congenital origin in ADPKD cannot be excluded. Patients with ADPKD present a number of vascular abnormalities, including cerebral aneurysms, heart valve lesions, coarctations of the aorta, and abdominal aortic aneurysms.5 Incidence of AVF secondary to venipuncture may be less than 0.03%. The brachial artery and the median cubital vein are anatomically very near each other and can thus easily communicate even with a simple puncture.4 It

is important that physicians be aware of this rare complication of venipuncture and avoid deep probing and running through with the needle. The natural history of AVF can be benign with spontaneous closure or persist and be symptomatic.9 Indications for repair of AVF include arterial or venous enlargement, symptoms secondary to venous engorgement, congestive heart failure, and worsening of symptomatic claudication.10 There are three treatment options: surgical repair, exclusion with a covered stent, and transcatheter embolization.11 In the patient reported here, his heart function was not impaired by the shunt, and finally its presence was utilized to construct sufficient vascular access for hemodialysis. In summary, this is a straightforward albeit unique case report of iatrogenic and/or congenital (patient with polycystic kidney disease) AVF that was superficialized and successfully used for hemodialysis. If any vascular anatomic variations are suspected, this should be verified by imaging studies since this may influence proper angioaccess planning for dialysis.

Abstract Antibiotics are potentially a cause of neurotoxicity in dialysis patients, the most common are the beta-lactams as ceftazidime and cefepime, and few cases have been reported after piperacillin/ tazobactam use. This report presents a case of a hypertensive and diabetic 67-year-old woman in regular hemodialysis, which previously had a stroke. She was hospitalized presenting pneumonia, which was initially treated with cefepime. Two days after treatment, she presented dysarthria, left hemiparesis, ataxia, and IX and X cranial nerves paresis. Computed tomography showed no acute lesions and cefepime neurotoxicity was hypothesized, and the antibiotic was replaced by piperacillin/tazobactam. The neurologic signs disappeared; however, 4 days after with piperacillin/ tazobactam treatment, the neurological manifestations returned. A new computed tomography showed no new lesions, and the second antibiotic regimen withdrawn. After two hemodialysis sessions, the patient completely recovered from neurological manifestations. The patient presented sequentially neurotoxicity caused by two beta-lactams antibiotics. This report meant to alert clinicians that these antibiotics have dangerous neurological effects in chronic kidney disease patients. Key words: Chronic kidney disease, hemodialysis, neurotoxicity, piperacillin/tazobactam
