This retrospective study compares outcomes of transposed brachiobasilic fistulae (avf), nontransposed avf, and grafts (avg). There were 161 (21%) transposed avf, 321 (42%) nontransposed avf, and 285 (37%) avg placed and followed over a 3-year period. Of the nontransposed avf, 203 (63%) were forearm radiocephalic avf and 118 (37%) were upper arm brachiocephalic avf. Grafts were able to be used in shorter time than avf and had a lower primary failure rate. However, avg had a significantly higher infection rate (0.23/patient/year vs. 0.07/patient/year) and required more procedures over the life of the access than avf (2.90/patient/year vs. 0.51/patient/year). Despite a higher primary failure rate, avf had better overall patency. Among nontransposed avf, brachiocephalic avf had significantly better primary patency than radiocephalic avf (p < 0.0001). Transposed avf had better cumulative patency than either nontransposed avf or grafts (p < 0.0001). Cumulative patency was best for transposed avf, intermediate for brachiocephalic avf, and worst with radiocephalic avf and avg. There was no difference in cumulative patency between radiocephalic avf and grafts (p = 0.5601). This analysis supports the current recommendation to prefer transposed avf over avg. In addition, the data suggest that both nontransposed brachiocephalic avf and transposed brachiobasilic avf outcomes may be superior to radiocephalic fistulae.

Neurovascular Complications Following Clavicle Fracture Fixation: Timing, Mechanisms, and Clinical Implications.
Cureus

Department of Orthopedic Surgery, Rutgers Robert Wood Johnson Medical School, New Brunswick, USA.
This review addresses the neurovascular complications associated with the surgical treatment of clavicle fractures through open reduction and internal fixation (ORIF). Despite being a generally safe procedure, it can lead to severe complications including brachial plexopathy, pseudoaneurysm, arteriovenous fistulas (AVF), deep vein thrombosis (DVTs), and thoracic outlet syndrome (TOS). One significant observation, not often highlighted in previous literature, is that neurovascular complications are more common in cases involving delayed fixation, nonunion, or malunion, compared to those treated acutely.

Article Synopsis
- The study investigated how different treatments (balloon angioplasty vs. drug-coated balloons) affect the changes in blood vessel tissues following arteriovenous fistula stenosis in pigs with chronic kidney disease.
- Significant differences in tissue composition were observed, with drug-coated balloons leading to lower neointimal growth and higher endothelial cell counts compared to standard angioplasty.
- The findings suggest that using drug-coated balloons may improve vessel healing and reduce complications over time, as shown by varied immune cell responses and tissue growth patterns.
Multimodal Treatment Approach for a Recurrent Hemorrhagic Scalp Arteriovenous Fistula: A Case Report.

Department of Neurosurgery, International University of Health and Welfare Narita Hospital, Narita, JPN.
Scalp arteriovenous fistula (AVF) is a rare vascular malformation that may present as a pulsatile scalp mass with complications like hemorrhage. We report a case of a large scalp AVF with recurrent bleeding, managed successfully with a multimodal approach. A 46-year-old man presented with a recurrently bleeding pulsatile scalp mass in the left temporal region, initially diagnosed as AVF following trauma.

Background: This research aimed to identify risk factors contributing to premature maturation of arteriovenous fistulas (AVF) in elderly diabetic patients and develop a clinical prediction model.
Methods: We conducted a retrospective review of 548 geriatric diabetic patients who underwent AVF creation for maintenance hemodialysis (MHD) at Baoding No 1 Central Hospital between January 2011 and December 2023. Patients were divided into mature (386) and immature (162) groups based on AVF maturation status.
Distal Hypoperfusion Ischemic Syndrome in a Patient With End-Stage Renal Disease.

Internal Medicine, Texas Tech University Health Sciences Center, Lubbock, USA.
Distal hypoperfusion ischemic syndrome (DHIS), also known as dialysis access steal syndrome (DASS), is a rare but significant complication in patients with end-stage renal disease (ESRD) undergoing hemodialysis through arteriovenous fistulas (AVFs). This case report presents a female patient in her 40s with a complex medical history, including peripheral arterial disease, coronary artery disease, and recurrent cellulitis affecting her right hand, who developed DHIS following the placement of a brachiobasilic AVF. Despite optimal medical management, the patient exhibited persistent ischemic symptoms, including hand coolness and necrosis, ultimately requiring surgical ligation of the AVF.
