This case video demonstrates a microsurgical technique for the clipping and obliteration of a Cognard V tentorial dural fistula. The patient was a 49-year-old male who presented with progressive upper and lower extremity weakness over 12 months, with associated cervical spinal cord edema. The patient was initially misdiagnosed with transverse myelitis, however abnormal flow voids on the MRI led to a cerebral angiogram being performed. The pre-operative angiogram demonstrated the Cognard V right tentorial dural arteriovenous fistula with drainage into the dorsal and ventral medullary veins...

We report the initial experience of the distal radial approach(DRA)via the anatomical snuffbox for various neuroendovascular procedures. DRA was attempted in 16 patients and catheterization of the targeted vessel was successfully performed in 15. In one patient, the puncture was successful, but the wire could not be advanced into the radial artery and a switch to the conventional transradial approach was needed. Among the 15 patients who underwent successful DRA, five patients underwent diagnostic cerebral angiography, five underwent coil embolization of a cerebral aneurysm, three underwent carotid artery stenting, one underwent liquid embolization of an arteriovenous malformation, and one underwent liquid embolization of a chronic subdural hematoma...

Coronary angiography is one of the most common procedures done in the United States and in other developed countries. For decades, the femoral artery has been the most common vascular access site utilized for this procedure. However, the radial access has been gaining popularity for being a safer and yet practical vascular access with substantial benefits. More recently, the novel distal transradial approach has proven to be an equally or perhaps safer vascular access for diagnostic and interventional coronary and noncoronary procedures...

The differential impact of young age and female gender on transradial access (TRA) outcomes remains to be confirmed. The primary objective was to assess the impact of young age and female gender on in-hospital net adverse cardiovascular events (NACE). Among 12 346 patients from the Coronary Angiogram Database of South Australia (CADOSA) Registry, the impact of gender; men (transfemoral access [TFA] 1995, TRA 6168) and women (TFA 1249, TRA 2934), and a median split of age, ≤63 years (TFA 1617, TRA 4727) and >63 years (TFA 1627, TRA 4375) were analyzed on in-hospital outcomes by creating 5 separate propensity-matched cohorts (entire cohort, men, women, ≤63 and > 63 years)...

BACKGROUND: TRA is recommended as the preferred approach to perform coronary angiography and PCI. Despite this, TRA-PCI is burdened by a high access site crossover rate. Assisted-tracking techniques (balloon-assisted tracking and pigtail-assisted tracking) have showed to solve some of the issues related with challenging TRA procedures, but few data exist about procedural outcomes. Aim of the study was to evaluate the efficacy and safety of the assisted-tracking (AsTra) techniques during transradial (TRA) percutaneous coronary intervention (PCI)...

Distal TRA is a novel access site in the interventional cardiology field, with current data demonstrating high success and infrequent complication rates - global procedural metrics that are comparable with historical proximal TRA. Distal TRA may conversely provide important advantages over proximal TRA, including patient comfort, shorter hemostasis time, and lower radial artery occlusion rates.

With respect to the transfemoral approach, transradial procedures enable a drastic reduction of bleeding events and are associated with a reduction of mortality. Radial artery spasm (RAS) is one of the most common complications and may lead to patient discomfort and procedural failure. Currently, there is no consensus on the optimal sedation protocol to avoid RAS. The aim of this study was to investigate the respective impact of opioids analgesia and inhalation sedation with a 50% nitrous oxide/oxygen premix (Kalinox) on pain and occurrence of RAS during transradial coronary procedures...

BACKGROUND: Many neurointerventionalists have transitioned to transradial access (TRA) as the preferred approach for neurointerventions as studies continue to demonstrate fewer access site complications than transfemoral access. However, radial artery spasm (RAS) remains one of the most commonly cited reasons for access site conversions. We discuss the benefits, techniques, and indications for using the long radial sheath in RAS and present our experience after implementing a protocol for routine use...

Peijian Wang, Qiulin Wang, Chen Bai, Peng Zhou
An aberrant right subclavian artery is a congenital aortic arch anomaly in which the right subclavian artery originates from the proximal descending aorta. The presence of an aberrant right subclavian artery can make right transradial coronary interventions more difficult and even lead to complications. Iatrogenic intramural hematomas and dissection of aberrant right subclavian arteries during transradial coronary angiography have been previously reported. We herein report a case of iatrogenic aortic dissection following attempts to perform right transradial coronary angiography in a patient with an aberrant right subclavian artery...

The transradial approach for coronary angiography and intervention is the preferred approach because of its superior safety profile as compared to the transfemoral approach. However, like all procedures, transradial approach is not free from complications. In this case, we describe a unique case of a large symptomatic radial artery pseudoaneurysm requiring urgent surgical intervention. The pseudoaneurysm developed after treatment with a short duration of subcutaneous low molecular weight heparin for radial artery occlusion that occurred a day after transradial coronary catheterization...

OBJECTIVES: To assess the independent predictors of patent and occlusive hemostasis (PH and OH, respectively) during radial hemostasis after coronary procedures. BACKGROUND: Radial artery occlusion (RAO) is a thrombotic complication of transradial catheterization that can lead to permanent occlusion of the radial artery. Sheath-vessel diameter ratio, postprocedure compression time, occlusive hemostasis, inadequate, and excessive anticoagulation are all predictors of RAO...
