Arteriovenous fistula is an infrequent complication of lumbar disc surgery. It is often not suspected, and the symptoms are diagnosed as deep venous thrombosis or heart failure. As a result of our review of the Brazilian literature and a survey of 3,500 Brazilian physicians, 5 cases of post-laminectomy arteriovenous fistula are added to the literature. A review of these cases shows that: (1) the right common iliac artery was injured in most cases, (2) the vena cava was frequently injured, and (3) direct repair was possible when the vena cava and the aorta were injured. A vascular prosthesis was necessary when the iliac arteries were damaged. The correct diagnosis is usually made by detection of an abdominal bruit in a patient with a history of lumbar disc surgery and is confirmed by arteriogram. Surgical treatment, either by suture or bypass, is the treatment of choice and results in cure.

General Surgery Residents Competence and Autonomy in Core Vascular Surgery Procedures.
J Surg Educ
January 2025
Division of Vascular Surgery, Department of Surgery, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin.
Objective: As vascular surgery has become increasingly sub-specialized, the scope of vascular care that general surgeons can be trained to provide has come into question. Thus, we sought to understand the competence and autonomy of general surgery residents (GSR) in core vascular surgery procedures.
Design: Three core operations in vascular surgery were identified: lower extremity (LE) amputations, arteriovenous fistula (AVF) creation, and LE embolectomy and thrombectomy (thromboembolectomy).
Spontaneous true brachial artery aneurysm: A case report from Somalia.
Int J Surg Case Rep
January 2025
Introduction And Importance: True brachial artery aneurysms are rather uncommon, due to their number of etiological factors. Besides inducing symptoms such as hand or digit ischemia, they may present as pulsative tumefactions and cause pain or paresthesias through nerve impingement. The diagnosis is based on duplex ultrasonography, CTA in the operational planning phase, and a physical examination.

Study Design: Systematic Review and Meta-analysis.
Objective: This study aims to compare the efficacy and safety of surgical and endovascular treatments for SDAVFs.
Summary Of Background Data: Spinal dural arteriovenous fistulas (SDAVFs) result from an abnormal connection between the radiculomeningeal artery and the radicular vein, leading to venous hypertension and potential neurological damage.
Introduction: Nicaragua is a Central American country with a high prevalence of patients with chronic kidney disease, particularly among young men. This is largely attributable to Mesoamerican nephropathy, a form of interstitial nephritis that predominantly affects young agricultural workers. While the majority of patients have access to chronic dialysis programs, a very small number have an option of receiving a renal transplant.

Cerebral proliferative angiopathy (CPA) is a rare subtype of cerebral arteriovenous malformation, characterized by unique angiographic features and clinical presentations. Although the clinical and angiographic characteristics of CPA have been well described, their impact on the surrounding tissues remains underexplored. Herein, we investigated the presence of calvarial thickening in patients with CPA, and discuss its potential pathogenesis.
