Intracranial Dural Arteriovenous Fistulae

Abstract BACKGROUND: Indocyanine green videoangiography (IGV) raises important limitations when we use it in vascular pathology, especially in cases with arterialization of the venous system such as arteriovenous malformations and fistulae. OBJECTIVE: Our objective was to provide a simple procedure that overcomes the limitations of conventional IGV. We define IGV in negative (IGV-IN), so-called because, in its first phase, the vessel to analyze is clipped, and we report 3 cases of intracranial dural arteriovenous fistulae treated with this procedure. METHODS: In 2011, we applied IGV-IN to 3 patients at our center with Borden type III intracranial arteriovenous fistulae. RESULTS: In all 3 cases, IGV-IN enabled both diagnosis and post-dural arteriovenous fistula exclusion control in 1 integrated procedure no longer than 1 minute, requiring only 1 visualization. CONCLUSION: IGV-IN is an improvement over the conventional IGV method and is able to provide more information in a shorter period of time. It is an intuitive and highly visual procedure, and, more importantly, it is reversible. Studies with larger samples are necessary to determine whether IGV-IN can further reduce the need for postoperative digital subtraction angiography.

Meningeal Artery

The preferred method for treating complex dural arteriovenous fistulae of the transverse and sigmoid sinuses is via endovascular, transarterial embolization using liquid embolysate. However, this treatment approach mandates access to distal dural feeding arteries that can be technically challenging by standard endovascular approaches. This video describes a left temporal craniotomy for direct stick microcatheterization of an endovascularly inaccessible distal posterior division of the middle meningeal artery for embolization of a complex left temporal dural arteriovenous fistula. The case was performed in the hybrid operative suite with biplane intraoperative angiography. Technical considerations, operative nuances, and outcomes are reviewed.The video can be found here: https://youtu.be/Dnd4yHgaKcQ.

Native arteriovenous fistula or interposition of a synthetic graft for vascular access is crucial for dialysis patients. Optimal surgical technique, microsurgery instrumentation and preventive hemostasis are considered beneficial for a successful surgical outcome. We describe a simple and novel maneuver using soft-feeding tubes to facilitate the manipulation of veins and perform successful anastomoses without using microsurgery instrumentation or vascular clamps during operations for vascular access.

BACKGROUND: An Arteriovenous fistula (AVF) is a creation of the natural blood vessels. It is a “gate of life” for the patients on hemodialysis. AIM: The study aimed to analyze the predictors for primary failure of AVF such as gender, age, number and location of AVF, and primary renal disease in patients with chronic kidney disease (CKD) stage 4/5.MATERIAL AND METHODS: The medical records of 178 created arteriovenous fistulae in patients with CKD stage 4/5, were retrospectively studied. Primary failure of AVF was defined as thrombosis or inability for cannulation of AVF within 3 months. Adequate maturation of AVF was defined as successful cannulation of AVF treatment and blood flow of > 600 ml/min.RESULTS: The mean age of the patients was 59.75 ± 14.65 years, and 65.16% (116/178) were men. Adequate maturation of AVF was achieved in 83.71% (149/178). Primary failure of AVF occurred in 16.29% (29/178) of the created fistulae, while 10.11% (18/178) had early thrombosis. The distal arteriovenous fistulae were significantly more frequently created in male patients (51 vs 18; p = 0.015). The female patients were significantly older than the male patients (63.27 vs 57.86 years; p = 0.018). CONCLUSION: Male gender was associated with better maturation of AVF. The age, number and location of AVF, and primary renal disease in patients with CKD stage 4/5 were not associated with primary failure of AVF.

Poor Outcome

Background and Purpose: Dural arteriovenous fistulae can present with hemorrhage, but there remains a paucity of data regarding subsequent outcomes. We sought to use the CONDOR (Consortium for Dural Arteriovenous Fistula Outcomes Research), a multi-institutional registry, to characterize the morbidity and mortality of dural arteriovenous fistula–related hemorrhage. Methods: A retrospective review of patients in CONDOR who presented with dural arteriovenous fistula–related hemorrhage was performed. Patient characteristics, clinical follow-up, and radiographic details were analyzed for associations with poor outcome (defined as modified Rankin Scale score ≥3). Results: The CONDOR dataset yielded 262 patients with incident hemorrhage, with median follow-up of 1.4 years. Poor outcome was observed in 17.0% (95% CI, 12.3%–21.7%) at follow-up, including a 3.6% (95% CI, 1.3%–6.0%) mortality. Age and anticoagulant use were associated with poor outcome on multivariable analysis (odds ratio, 1.04, odds ratio, 5.1 respectively). Subtype of hemorrhage and venous shunting pattern of the lesion did not affect outcome significantly. Conclusions: Within the CONDOR registry, dural arteriovenous fistula–related hemorrhage was associated with a relatively lower morbidity and mortality than published outcomes from other arterialized cerebrovascular lesions but still at clinically consequential rates.

Ultrasound Surveillance

Background: Duplex ultrasound surveillance with pre-emptive treatment of an identified stenosis is increasingly being utilised to help maintain arteriovenous fistula patency. This study aims to determine whether post-operative duplex ultrasound surveillance can improve fistula patency at 12 months and improve the proportion of ‘pre-haemodialysis’ patients commencing haemodialysis via a usable fistula. Methods: All arteriovenous fistulae formed between 1st January 2015 and 31st August 2017 in a single, tertiary vascular centre were included. Primary and secondary patency at 12 months, along with the proportion of pre-haemodialysis patients commencing haemodialysis via a usable arteriovenous fistula, were compared between the fistulae undergoing duplex ultrasound surveillance and ‘standard practice’. Results: Two hundred forty-one arteriovenous fistulae were created in 216 patients. A higher proportion of brachiobasilic transposition arteriovenous fistula and patients undergoing arteriovenous fistula creation following a previously failed access were identified in the duplex ultrasound surveillance group. Primary patency at 12 months (hazard ratio = 0.43, 95% confidence interval = 0.30–0.61, p < .001) was significantly lower in the duplex ultrasound surveillance group compared with the ‘standard practice’ group. Despite this, no difference was identified in secondary patency at 12 months (hazard ratio = 1.82, 95% confidence interval = 0.87–3.80, p = .112). No difference was also identified in the proportion of pre-haemodialysis patients starting haemodialysis with a usable arteriovenous fistula (duplex ultrasound surveillance = 65.0% vs standard practice = 77.8%; odds ratio = 0.53, 95% confidence interval 0.58–1.19, p = .279). Conclusion: Post-operative duplex ultrasound surveillance following arteriovenous fistula formation is associated with higher rates of post-operative intervention; however, this does not translate into improved secondary patency or the proportion of pre-haemodialysis patients commencing HD via their fistula.

Arteriovenous fistulae of the superficial temporal artery are rare, and their principal cause is traumas. Complications include pulsatile mass, headache, hemorrhage and deformities that compromise esthetics. Treatment can be performed using conventional surgery or endovascular methods. The authors describe a case of a 44-year-old male patient who developed a large pulsating mass, extending from the preauricular region to the right parietotemporal and frontal regions after a motorcycle accident. The treatment chosen was complete surgical removal of the pulsatile mass and ligature of the vessels feeding the fistula.

Abstract: Arteriovenous fistulae present in any of a number of characteristic locations in the brain, such as the ethmoidal region, the petrosal sinus, and the transverse sinus and torcula. The fistula is an abnormal connection between an artery and vein. While there are multiple accepted classification systems, the risk they represent to the patient depends primarily on the degree of reflux of the venous drainage back to the cortex of the brain. While the inflow and outflow may be very complex, isolation of the fistulous point where this abnormal connection occurs is the key to successful treatment. This may be achieved through either endovascular or open surgical techniques deoending on the anatomy.

Tentorium Cerebelli

Tentorial dural arteriovenous fistulae are rare intracranial fistulae, in which the fistula pocket is present within the leaves of tentorium cerebelli. These tentorial fistulae can be rarely present near the galenic complex, where they can engorge the deep venous system and cause symptoms of venous hypertension. We present an interesting case of endovascular treatment of a galenic tentorial dural arteriovenous fistula in a patient with headaches and imbalance. The fistula was accessed through the artery of Davidoff and Schecter from the posterior cerebral artery supplying the fistula. The fistula was completely embolized using Onyx and with preservation of vein of Galen.The video can be found here: http://youtu.be/igX2X5tfvrg.
