Vascular access thrombosis is an important complication with great impact on access patency and, consequently, on a patient’s quality of life and survival. We report the case of a 73-year-old woman with chronic kidney disease on hemodialysis with a radiocephalic arteriovenous fistula on the right arm that was brought to the emergency department with decreased strength in her right arm, ipsilateral hypoesthesia and facial hemi-hypoesthesia. The patient was given a brain computed tomographic scan that did not confirm suspicion of stroke. On re-examination, the patient had new-onset pain at arteriovenous fistula level, and her right arm was cold and pale. The nephrology department was called for arteriovenous fistula evaluation. On physical examination, her forearm fistula had a decreased thrill and arm elevation exacerbated its paleness. A bedside ultrasound was performed for arteriovenous fistula assessment. Doppler ultrasound revealed: partial thrombosis at brachial bifurcation, a flow of 80–105 mL/min at brachial artery level and a radial artery with a damped waveform. Anastomosis and draining vein were permeable. In this case, the diagnosis of acute embolic brachial artery occlusion was made by a fast bedside ultrasound evaluation. The patient underwent thromboembolectomy with Fogarty technique, recovering fistula thrill, radial and cubital pulses. Thromboembolism of the fistula feeding artery is a rare cause of vascular access thrombosis and it is rarely mentioned in the literature. In this report, failure to recognize the upper limb ischemia would have led to delayed treatment, potentially resulting in the fistula’s complete thrombosis and further limb ischemia. We highlight the importance of a diagnosis method like Doppler ultrasound, which allows for rapid evaluation at the patient’s bedside.

Background and Purpose: Transradial access (TRA) for neuroendovascular procedures is increasing in prevalence, although numerous procedures are still performed using transfemoral access (TFA). Some cardiology studies have suggested the safety benefits of TRA at a patient level may be offset at a population level by a paradoxical increase in TFA vascular access site complications (VASCs) associated with radial adoption, the so-called “radial paradox.” We studied the effect of TRA adoption on TFA performance and VASC rates in neuroendovascular procedures. Methods: Data were collected for all neuroendovascular procedures performed over a 10-month period by trainees after implementation of a radial-first paradigm at a single center. Results: Over the study period, 1,084 procedures were performed, including 689 (63.6%) via TRA and 395 (36.4%) via TFA. In comparison to TRA, TFA cases were performed in older patients (TFA 63 ±15 vs. TRA 56 ±16), were predominantly male (TFA 52.9% vs. TRA 38.6%), used larger sheath sizes (≥7 French, TFA 56.6% vs. TRA 2.3%), were more often emergent (TFA 37.7% vs. TRA 1.1%), and used tPA administration (TFA 15.3% vs. TRA 0%) (p<.001 for all comparisons). Overall, 29 VASCs occurred (2.7%), including 27 minor (TFA 4.6% [18/395] vs. TRA 1.3% [9/689], p=.002) and 2 major (TFA 0.3% [1/395] vs. TRA 0.1% [1/689], p>.99) complications. After multivariate analysis, independent predictors of any VASC included TFA (OR 2.8, 95% CI 1.1-7.4) and use of dual antiplatelets (OR 4.2, 95% CI 1.6—11.1). Conclusions: TFA remains an essential route for neuroendovascular procedures, accounting for 36.4% of cases under a radial-first paradigm. TFA is disproportionately performed in patients undergoing procedures with an increased-risk for VASCs, though the minor and major VASC rates are comparable to historical controls. TFA proficiency may still be achieved in radial-first training without an increase in femoral complications.

Effective revascularization of the patient with peripheral artery disease is about more than the procedure. The approach to the patient with symptom-limiting intermittent claudication or limb-threatening ischemia begins with understanding the population at risk and variation in clinical presentation. The urgency of revascularization varies significantly by presentation; from patients with intermittent claudication who should undergo structured exercise rehabilitation before revascularization (if needed) to those with acute limb ischemia, a medical emergency, who require revascularization within hours. Recent years have seen the rapid development of new tools including wires, catheters, drug-eluting technology, specialized balloons, and biomimetic stents. Open surgical bypass remains an important option for those with advanced disease. The strategy and techniques employed vary by clinical presentation, lesion location, and lesion severity. There is limited level 1 evidence to guide practice, but factors that determine technical success and anatomic durability are largely understood and incorporated into decision-making. Following revascularization, medical therapy to reduce adverse limb outcomes and a surveillance plan should be put in place. There are many hurdles to overcome to improve the efficacy of lower extremity revascularization, such as restenosis, calcification, microvascular disease, silent embolization, and tools for perfusion assessment. This review highlights the current state of revascularization in peripheral artery disease with an eye toward technologies at the cusp, which may significantly impact current practice.

Endovascular Approach

Background: Major vascular access site complications remain a challenge in the field of TAVI and are associated with higher 30 day mortality. However, outcomes following endovascular management with covered stents for such complications are not well established. Methods: We reviewed the one year data of patients who underwent TAVI at our institution with a Sapien valve by percutaneous femoral approach. Identified were patients who suffered major vascular complications according to the definitions set forth by the Valve Academic Research Consortium. We then compared the outcome of patients managed by an endovascular approach with a population whose femoral access site complications were managed surgically/endovascularly (85.7% surgically), as reported from the Partner trial. Results: A total of 16 patients experienced Major Vascular complications. TAVI was aborted on 2 patients due to access site complication. Excluded were 3 patients who had benign small ascending aortic dissections after successful valve deployment and 3 patients who were managed surgically. Ten remaining patients were managed by a pure endovascular approach with covered stents. Four of these patients suffered ilio-femoral dissection, 4 had perforation and 2 had both perforation and dissection. No significant difference was observed in pre and post procedure creatinine (1.01 vs 1.14, p=0.16) and none required dialysis within 30 days, as compared with 8.1% in Partner trial. We observed no statistically significant difference between the Partner trial cohort and our patients in 30 day all cause mortality (14.1% vs 10%, p=1), stroke rate (4.8% vs 0%, p=1), access site hematoma (22.9% vs 0%, p=0.1), retroperitoneal bleed (9.5% vs 0%, p=0.6), pseudoaneurysm (3.4% vs 0%, p=1), and gastrointestinal ischemia (1.6% vs 0%). No access site infection, stent thrombosis, or stenosis leading to limb ischemia were noted clinically at 30 day follow-up. Conclusion: Many patients with major vascular complications during TAVI can be treated with a pure endovascular approach. In our small series we observed no difference in concurrent complications when an endovascular repair can be rapidly initiated as compared to a primary surgical approach.
