PURPOSE: To retrospectively investigate the safety and efficacy of hybrid proximal coiling of various medium-sized vessels (4 to 8 mm) using the Penumbra Occlusion Device (POD). MATERIALS AND METHODS: From October 2014 to February 2016, 37 proximal embolizations were performed with PODs in 36 patients (mean age: 50.8, range: 10-86; 29 male, 7 female). Vessel occlusions were achieved under fluoroscopic guidance using a 2.7 French microcatheter. Among the 36 vessels targeted, 16 were splenic arteries, 11 renal arteries, 4 mesenteric arteries, 3 arteriovenous fistulae, 1 iliac artery, and 1 gonadal vein...

Subdural arteriovenous fistula (SDAVF) is a rare condition characterized by clinical manifestations ranging from mild bilateral sensory deficits to quadriplegia. The diagnosis is often delayed due to unspecific neurological symptoms, initially diagnosed as polyneuropathy or myelopathy. The diagnosis can be delayed for as long as 1-15 years. The following report describes a cervical SDAVF case initially misdiagnosed as myelitis transversa and treated with intravenous steroids. A 56-year-old male presented with sensory deficits and mild leg and right arm weakness...

We report a case of nonischemic priapism following brachytherapy. A 63-year-old man presented 22 days after brachytherapy for prostate cancer. He suffered painless sustained incomplete erection for a few days. The patient was diagnosed with nonischemic priapism by cavernosal blood gas analysis. Right internal pudendal arteriography showed blood pooling in the cavernosum caused by arteriovenous fistula. Selective arterial embolization with gelatin sponge particles was performed and detumescence achieved. To our knowledge,this is the first case of high flow priapism caused by brachytherapy for prostate cancer...

BACKGROUND: Chronic hemodialysis is a risk factor for invasive bacterial infections. We conducted a nationwide study of risk and mortality of infective endocarditis (IE) among patients undergoing chronic hemodialysis. METHODS: In this observational cohort study, patients with end-stage renal disease who initiated hemodialysis in Denmark during 1990 to 2010 were matched on age, gender, and municipality with up to 19 population controls. We extracted information on first admissions with IE, comorbidity, and arteriovenous fistula surgery from medical administrative databases...

OBJECTIVE: Describe the construction of arteriovenous fistula for hemodialysis in chronic renal patient on hemodialysis who presented chronic arterial obstruction in the upper limb. METHODS: A surgical procedure was performed on a patient with obstruction of the brachial artery in its proximal third. The procedure was carried out by the construction of a bypass with autologous vein between the proximal brachial and distal brachial arteries and the performing of an arteriovenous fistula with superficialized and anteriorized basilic vein, with anastomosis in the bypass at the same surgical procedure...

BACKGROUND: Native arteriovenous fistulae (AVFs) are preferred while central venous catheters (CVCs) are least suitable vascular access (VA) in patients requiring hemodialysis (HD). Unfortunately, around 80% of patients start HD with CVCs. Late referral to nephrologist is thought to be a factor responsible for this. We retrospectively analyzed the types of VA at HD initiation in renal transplant recipients followed by nephrologists with failed transplant. If early referral to nephrologist improves AVF use, these patients should have higher prevalence of AVF at HD initiation...

The authors report on an 81-year-old woman with a pathologic hangman's fracture secondary to a complex arteriovenous fistula (AVF). The patient presented with severe, unremitting neck pain and was found to have fractures bilaterally through the pars interarticularis of C-2 with significant anterior subluxation of C-2 over C-3 along with widening of the left transverse foramen. Due to an abnormally appearing left vertebral artery (VA) on CT angiography, the patient underwent conventional angiography, which revealed a complex AVF stemming from the left VA at the level of C-2 with dilated posterior cervical veins and a large venous varix...

BACKGROUND: Cerebral dural arteriovenous fistulas (DAVFs) are rare intracranial vascular lesions but can cause significant morbidity and mortality. OBJECTIVES: To analyze the effect of the center's experience on DAVF embolization efficacy and safety. METHODS: From May 2008 to October 2014, 57 embolization procedures were attempted on 48 patients (37 men and 11 women; median age: 63.9 years) for DAVF in a single center. DAVF presented with cortical venous reflux in 44/48 cases (91...

The usual manifestation of brachial artery aneurysms is the incidental finding of a swelling of the arm, combined with paresthesia or pain in some cases. The etiology is often traumatic or secondary to drug abuse. Pathophysiology of brachial artery dilation in these cases is not completely clear. We herein describe a case of a 61-year-old male presenting with a giant, painful, pulsatile mass on his left arm. He was submitted to a cadaveric kidney transplant in 2005. He had a functioning arteriovenous fistula (AVF) on his right arm, and a spontaneously thrombosed radiocephalic AVF on his left arm...

Renal arteriovenous fistula (AVF) is an uncommon anomaly characterized by the communication between renal arteries and veins. Renal AVFs are often asymptomatic but are occasionally accompanied by hematuria or heart failure. Transcatheter closure with embolization is a safe and effective treatment for renal AVF. We herein report an 87-year-old patient with heart failure due to renal AVF who was treated by transcatheter embolization. She developed bacteremia with hydronephrosis, which is a rare complication following the embolization of renal AVF...

OBJECTIVE: Delayed maturation of arteriovenous fistulae (AVF) among patients who require hemodialysis (HD) can lead to catheter sepsis with its resultant morbidity and mortality. Some have proposed that sequential balloon-assisted maturation (BAM) may accelerate the maturation times of these accesses. On the other hand, serial balloon angioplasty of normal vein may result in stenosis and delay maturation. Although the safety of BAM has been shown, direct comparison to non-matured AVF has not been explored...

A 24-year-old male presented with classic features of the nephrotic syndrome. An initial renal biopsy revealed minimal change disease and thereafter, a second biopsy showed features of focal and segmental glomerulosclerosis. There was no response to conventional immunosuppression, and the patient had to be given rituximab; in spite of this, he went on to develop end-stage renal disease. He continued to have heavy proteinuria leading to severe hypoalbuminemia, thrombosis, infections, and malnutrition, placing the patient in a life-threatening situation...

An idiopathic renal arteriovenous (AV) fistula is a rare malformation of the kidney that may present insidiously with heart failure or hematuria. The treatment may be challenging due to large fistula size that may limit endovascular management. The authors report a case of an 85-year-old Caucasian woman who presented with acute heart failure and was found to have a right renal AV fistula. Since she had no prior history of renal intervention or trauma, a diagnosis of idiopathic renal AV fistula was made. She was managed by endoluminal occlusion using multiple stainless steel coils and Amplatzer vascular plug II device...

BACKGROUND: Spontaneous spinal epidural hematoma (SSEH) is a rare neurological emergency of the spinal cord. Its etiology and treatment strategy remain controversial. This study aimed to evaluate a significant cause of SSEH and to discuss the treatment strategy according to the clinical outcomes of patients in two institutions. METHODS: Fifty-five cases of SSEH treated at our institutions between February 2002 and February 2016 were retrospectively analyzed. RESULT: The mean age of the first SSEH onset was 31...

BACKGROUND: -Spinal arteriovenous shunts are a common spinal vascular disorder. However, they can have a misleading clinical presentation and poor prognosis. They are classified into 4 types according to shunt points and drainage route, among which extradural arteriovenous fistula (eAVF) is the most rare, comprising only 1% of all spinal arteriovenous shunts. Here, we report an extremely rare case of coexistent eAVF at the craniocervical junction and soft tissue arteriovenous malformation (AVM) within the same metamere...
