BACKGROUND: Arteriovenous malformation (AVM)-associated aneurysms are common, being reported in 15% of cases. In regards to ruptured posterior fossa AVMs, associated aneurysms are present in 48% of cases and are the etiology of the bleed in 37%. We present a 75 year-old female who presented with a subarachnoid hemorrhage (SAH) secondary to a ruptured aneurysm arising from a flow-related basilar perforator artery feeder of an anterior pontine AVM. We report the successful treatment of the aneurysm with coil embolization...

OBJECTIVE: Factors associated with favorable outcome following stereotactic radiosurgery (SRS) for dural arteriovenous fistulas (DAVFs) with cortical venous reflux (CVR) are incompletely understood. The aim of this retrospective cohort study is to assess the outcomes after SRS for high-grade DAVFs and identify predictors. METHODS: We performed a retrospective review of consecutive patients with high-grade DAVFs, defined as the presence of CVR, who underwent SRS between 1989 and 2017...

May-Thurner Syndrome (MTS) is a condition in which the left common iliac vein is compressed by the right common iliac artery, which may cause swelling, pain or deep venous thrombosis of the left lower extremity1 .Post-thrombotic syndrome, non-thrombotic chronic venous insufficiency and recurrence after venous thrombosis are also possible complications. Although MTS combined with left iliac arteriovenous fistula (AVF) is rarely reported, we treated three such cases in the past year.

OBJECT: Stereotactic radiosurgery (SRS) is widely used to treat brain arteriovenous malformation (AVM); however, detailed information on late radiation-induced complications (LRICs) is scarce. The goal of the present study was to characterize the incidence, risk factors, and clinical outcomes of LRICs based on our long-term follow-up data. METHODS: The outcomes of consecutive patients who underwent SRS for AVMs at our institution in 1990-2010 were analyzed. Cyst formation/encapsulated hematoma (CF/EH) and radiation-induced tumor (RIT) were defined as LRICs...

OBJECTIVE: To report the surgical treatment of a high-flow femoro-femoral arteriovenous fistula (AVF), a rare complication of intravenous drug abuse. CASE REPORT: A 36-year-old woman with history of intravenous heroin and cocaine abuse presented with right lower limb oedema, inguinal bruit and heart failure. Duplex ultrasound examination and CT-angiography showed a large, high-flow AVF involving the common femoral vein and the superficial femoral artery, associated with thrombosis of the great saphenous vein and an important inflammation in the right groin, without active bleeding...

It is debated whether the efficacy and long-term safety of gamma knife radiosurgery (GKRS) for arteriovenous malformations (AVMs) differs between adult and pediatric patients. We aimed to clarify the long-term outcomes of GKRS in pediatric patients and how they compare to those in adult patients. We collected data for 736 consecutive patients with AVMs treated with GKRS between 1990 and 2014 and divided the patients into pediatric (age < 20 years, n = 144) and adult (age ≥ 20 years, n = 592) cohorts. The mean follow-up period in the pediatric cohort was 130 months...

BACKGROUND: A displaced bronchus is a rare disorder of the left upper lobe. Displaced bronchi are often accompanied by an anomaly of a pulmonary artery, but rarely of a pulmonary vein. CASE PRESENTATION: We here present a patient with primary lung cancer and simultaneous migration abnormalities of the pulmonary artery and vein in a displaced bronchus of the left upper lobe. Previous reports and our findings indicate that anomalies of the pulmonary artery and vein combined with a displaced bronchus of the left upper lobe have the following characteristics: (1) the left main pulmonary artery does not cross the dorsal side of the displaced bronchus; (2) V1 + 2 returns to the inferior pulmonary vein; and (3) there is an accessory fissure (aberrant fissure) in the segments dominated by the displaced bronchus...

Intracranial dural arteriovenous fistulae (DAVF) within the deep cerebral vasculature are diagnostically challenging because of their variable clinical presentation and typical bilateral neuroimaging findings mimicking inflammatory, infectious, and metabolic processes. Increasingly, reports have emerged highlighting the diagnostic and treatment challenges of these lesions and their associated high morbidity and rapid clinical deterioration when untreated. We describe here a case series of 4 patients with deep cerebral DAVF who presented with impaired arousal or memory and behavioral changes...

BACKGROUND: Microsurgery (MS) and stereotactic radiosurgery (SRS) remain the preferred interventions for the curative treatment of brain arteriovenous malformations (AVM), but their relative efficacy remains incompletely defined. OBJECTIVE: To compare the outcomes of MS to SRS for AVMs through a retrospective, matched cohort study. METHODS: We evaluated institutional databases of AVM patients who underwent MS and SRS. MS-treated patients were matched, in a 1:1 ratio based on patient and AVM characteristics, to SRS-treated patients...

OBJECTIVES: The present study describes the use of octreotide (OCT) in patients with atrial fibrillation (AF) receiving oral anticoagulation (OAC) who have gastrointestinal (GI) bleeding related to arteriovenous malformations (AVMs), as well as its effect on OAC tolerance and subsequent rebleeding. BACKGROUND: AVMs cause significant GI bleeding, especially in patients with AF who are receiving OAC for stroke prevention. OCT has been shown to minimize recurrent GI bleeds related to AVMs...

OBJECTIVE: The arterial to end-tidal carbon dioxide tension difference (CO2 gap) correlates with physiologic dead space. The prognostic value of increased CO2 gap in trauma and respiratory distress patients is documented. Transpulmonary arteriovenous shunting is identified as a predictor of mortality in non-pulmonary sepsis. We set out to investigate the prognostic value of the CO2 gap in a pilot study of patients with suspected sepsis from non-respiratory causes. METHODS: Patients presenting to tertiary Australian ED with suspected sepsis (n = 215) underwent near-simultaneous end-tidal carbon dioxide and partial pressure of carbon dioxide measurements...

Glomus tumor is a rare benign mesenchymal neoplasm derived from the glomus body, an arteriovenous shunt mainly located in dermis and subcutis. The most common localization of this tumor is extremities, especially nailbed. Glomus tumor in the gastrointestinal system is a rare condition. Here we report a gastric glomus tumor to raise awareness of this tumor and show the difficulties in the diagnosis.

Stereotactic radiosurgery (SRS) is a promising treatment for medically intractable mesial temporal lobe epilepsy. SRS for epilepsy has had an acceptable safety profile with reports of radiation-induced vascular malformations confined to central nervous system pathologies with prominent angiogenesis - namely, primary brain tumors, metastases, and arteriovenous malformations. Theoretical risks for radiation-induced lesions following radiosurgery for epilepsy have yet to be established. Of 13 patients treated in a pilot trial for medial temporal lobe epilepsy, one developed multiple delayed radiation-induced cavernous malformations following radiosurgery...

OBJECTIVES: Bilateral upper cerebellar hemorrhage is extremely rare clinical entity, but relatively known as postoperative neurosurgical complication with as yet unknown etiology. Here, we report a case of bilateral upper cerebellar hemorrhage due to pial arteriovenous fistula and discussed possible pathophysiology of this bleeding pattern.

REVIEW
Nitesh N Rao, P Toby Coates
Renal transplantation is the preferred treatment for patients with end-stage kidney disease. However, despite successful kidney transplantation, cardiovascular disease (CVD) remains one of the major causes of patient death and hence graft loss. The antecedents of this increased risk reside within the development of end-stage kidney disease and dialysis. Risk factors for the development of CVD include diabetes, hypertension, and dyslipidemia. Other transplant-specific factors include the presence of a patent arteriovenous fistula and immunosuppressive therapy...

OBJECTIVE: To evaluate the feasibility and safety of transvenous embolization treatment for brain arteriovenous malformations (bAVM). METHODS: Between November 2016 and August 2017, a transvenous endovascular embolization protocol was implemented at the Henan Provincial People's Hospital for consecutive patients with ruptured bAVM. Therapeutic decision making was based on Spetzler-Martin grades, bAVM location, pattern of venous drainage, and angioarchitecture. And the transvenous embolization procedure was combined with transarterial support...
