OBJECTIVES: Arteriovenous malformations (AVMs) are complex vascular lesions. Surgical excision is the treatment of choice, but is often not achievable. Embolo-sclerotherapy alone is associated with high recurrence rates. This study tested the hypothesis that seeding hydrogel conditioned bone marrow derived mesenchymatous stem cells (BM-MSCs) in an AVM nidus model induces solid microvascular occlusion through endoluminal tissue growth. METHODS: AVMs were modelled as arteriovenous microvascular nidus, using swine rete mirabile, a plexiform intracranial structure composed of arterial microvessels that extensively anastomose...

BACKGROUND: Spinal cord arteriovenous shunts (scAVSs) are a group of lesions located in the spinal cord itself or in the surrounding structures. The most common scAVSs are spinal dural arteriovenous fistulas (sDAVFs), which are acquired lesions. The pathogenesis of sDAVFs involves thrombosis and venous hypertension as trigger factors. Intradural scAVSs such as spinal cord arteriovenous nidus type malformations (AVMs) and pial arteriovenous fistulas are less common than sDAVFs and are considered to have a so-called 'congenital' origin...

BACKGROUND: Onyx is important embolic material in the endovascular treatment of intracranial dural arteriovenous fistula (DAVF). However, its impact on DAVF occlusion rates, morbidity, mortality, and complication rates is not fully examined. OBJECTIVE: To improve understanding of safety and effectiveness profiles associated with transarterial endovascular treatment using Onyx for intracranial DAVF. METHODS: We analyzed data from our prospective clinical registry and conducted a systematic review of all previous transarterial embolization studies using Onyx published between January 2005 and December 2015 in MEDLINE and EMBASE...

Vein of Galen malformations (VOGMs) are rare developmental cerebrovascular lesions characterized by fistulas between the choroidal circulation and the median prosencephalic vein. Although the treatment of VOGMs has greatly benefited from advances in endovascular therapy, including technical innovation in interventional neuroradiology, many patients are recalcitrant to procedural intervention or lack accessibility to specialized care centers, highlighting the need for improved screening, diagnostics, and therapeutics...

Background and purpose Transvenous embolization (TVE) is widely utilized as an effective and safe treatment option for cavernous sinus dural arteriovenous fistula (CS-dAVF); however, detecting the exact location of the fistula is challenging. The present study identified the angiographic features of the fistulous point and evaluated the match with the microcatheter tip and fistulous point. Materials and methods An analysis cohort of 45 consecutive patients with CS-dAVF treated by TVE was analyzed retrospectively...

Arteriovenous fistula is the preferred option for vascular access in hemodialysis patients. The aim of this study was to assess different follow-up methods for hemodialysis patients in our hemodialysis center in China. A cohort of 124 patients with stage 3 chronic kidney disease was recruited and double-blind randomly assigned into two groups. Patients in Group A received phone calls to schedule their next consultation a week in advance. Patients in Group B scheduled their next appointment at the end of each visit...

BACKGROUND: A minority of patients undergoing posterior component separation (PCS) have abdominal wall defects that preclude complete reconstruction of the visceral sac with native tissue. The use of absorbable mesh bridges (AMB) to span such defects has not been established. We hypothesized that AMB use during posterior sheath closure of PCS is safe and provides favorable outcomes. METHODS: We performed a retrospective review of consecutive patients undergoing PCS with AMB at two hernia centers...

Rainer Wirth
The technique of percutaneous endoscopic gastrostomy (PEG) was introduced in 1979 as a semi-invasive approach for children with the need for a gastric fistula in order to avoid an operative intervention. The suture pull-through method was rapidly established and is now omnipresent. Because scientific evidence is broadly missing, there is some uncertainty about the indications in geriatric medicine. Guidelines do not recommend the insertion of a PEG in patients with severe dementia and malnutrition. Tube feeding is mainly recommended as a temporary method for patients who cannot take oral nutrition for more than 3 days or for whom the energy intake for more than 10 days presumably covers less than 50% of their needs, assuming that the overall prognosis is reasonable...

Large-vessel chronic traumatic arteriovenous fistulas are a rare complication after trauma. Delayed presentation can consist of one or more features of high-output cardiac failure, pulsatile abdominal mass, bruit, limb ischemia, and venous congestion. We describe a patient with a complex iliocaval fistula secondary to a remote gunshot wound associated with a large 8.5-cm aortic aneurysm. Informed consent of the patient was obtained for publication of the case.

Subclavian steal syndrome (SSS) has been well described in the setting of subclavian stenosis. We describe an unusual case of SSS caused by a high-flow arteriovenous dialysis fistula in the absence of subclavian stenosis, provide a review of the literature, and propose that arteriovenous fistula-induced SSS is an underdiagnosed cause of syncope in this population of patients.

The cephalic arch is a common location of stenosis, especially in brachiocephalic fistulas. The cephalic arch has a number of anatomic variations. Cephalic arch stenoses are often resistant and have poor primary patency. Here we describe an unusual case of a hemodialysis patient with a single-conduit supraclavicular cephalic arch draining into the external jugular vein presenting with recurrent cephalic arch stenoses and external jugular vein stenosis. In our view, extrinsic compression by the clavicle may contribute to the high rate of recurrence, the lack of complete dilation of even high-pressure balloons, and a theoretically heightened risk of rupture when cutting balloons are used...

A 62-year-old man presented to our department with abdominal pain and diarrhea for 3 weeks on a background of previous branched endovascular repair for a thoracoabdominal aneurysm. A triple-phase computed tomography scan of his abdomen and pelvis showed a large aortocaval fistula caused by a type III endoleak from a dislodged superior mesenteric artery stent. He was successfully treated with a BeGraft (Bentley Innomed, Hechingen, Germany) by using an endovascular technique.

Mask ventilation, the first step in airway management, is a rescue technique when endotracheal intubation fails. Therefore, ordinary airway management for the induction of general anesthesia cannot be conducted in the situation of difficult mask ventilation (DMV). Here, we report a case of awake intubation in a patient with a huge orocutaneous fistula. A 58-year-old woman was scheduled to undergo a wide excision, reconstruction with a reconstruction plate, and supraomohyoid neck dissection on the left side and an anterolateral thigh flap due to a huge orocutaneous fistula that occurred after a previous mandibulectomy and flap surgery...

Air embolism developing from an atrial-esophageal fistula that was created as a complication from an atrial ablation procedure is a rare, yet usually fatal diagnosis. Neurologic manifestations such as meningitis, altered mental status, seizures, strokes, transient ischemic attacks (TIAs), psychiatric changes, and coma can ensue. Imaging of the brain might reveal infarcts, cerebral edema, as well as signs of pneumocephalus. This case describes a 42-year-old male with recent cardiac ablation procedure at an outside hospital for refractory atrial fibrillation (A-fib) who presented with altered mental status, dyspnea and diaphoresis...
