Synthetic vascular access for hemodialysis exhibits biological and mechanical material properties mismatch with the native vessels. These limitations prevent infiltration of endothelial cells and decrease grafts long-term patency, particularly in small diameter vessels. We aimed to design a curved structural reinforced small intestinal submucosa (SIS) vascular graft for hemodialysis access and to evaluate in a porcine animal model graft patency by Doppler ultrasonography, tissue remodeling by histology, and vascular wall Young's modulus after implantation by biaxial tensile test...

BACKGROUND: Arteriovenous (AV) fistulae is an extremely rare disease of vascular malformation that involves fistulae formation between the systemic and pulmonary AV systems. CASE REPRESENTATION: This case report describes a rare systemic-pulmonary AV fistulae of congenital origin, accompanied by pulmonary hypertension, as determined by aortic angiography and echocardiography. CONCLUSION: Characteristics, diagnosis, and therapeutic approaches of this rare abnormality are explored...

Spinal dural arteriovenous fistulas (AVFs), being the most commonly encountered spinal vascular malformations, result in considerable morbidity with progressive spinal cord symptoms. A selective spinal digital subtraction angiography (DSA) is needed to confirm the diagnosis, to better evaluate the fine vascular structures and to plan therapy. With the introduction of three-dimensional rotational angiography (3D-RA), the information available for the treating physician has vastly increased. In the following article, we present a case series of four patients, in which the advantages of 3D-RA over the conventional biplane projections could be observed clearly...

Dysfunction of arteriovenous access for hemodialysis is a challenge for the vascular surgeon. Some patients have complex vascular access with problems that are difficult to solve. Careful analysis of the vascular network with ultrasound and dissection of the veins during surgery can help to identify the best option for each access. We introduce and discuss the case of creation of a radio-cephalic fistula with outflow into the brachial vein in 64-year-old hemodialysis male patient. This technique enables extending fistula patency, arterializing the brachial vein, and improves cost efficiency...

An 8-y-old female rhesus macaque (Macaca mulatta) presented for swelling of the left lower limb distal to the inguinal region and associated with the femoral artery. Physical and ultrasound examinations suggested an arteriovenous fistula combined with a pseudoaneurysm. After review of possible treatment options, we determined that open surgical repair was the best course of action. The pseudoaneurysm and arteriovenous fistula were surgically resected, and the macaque recovered without complication.

Isolated intraventricular hemorrhage due to dural arteriovenous fistula (dAVF) is extremely rare and has been reported only a few times in the literature. The pathophysiological cause of isolated intraventricular hemorrhage in these cases was hypothetically attributed to retrograde venous flow into subependymal vessels, although none of these cases demonstrated radiographic evidence of such reflux. We present the first case of a dAVF with radiographic evidence of severe cortical venous reflux into the subependymal venous network causing isolated intraventricular hemorrhage, thus lending proof for the underlying pathophysiology...

BACKGROUND AND PURPOSE: Engorged medullary vein (EMV) in patients with intracranial dural arteriovenous fistula (DAVF) suggests venous congestion. The aim of this study is to investigate its prevalence, pattern, and correlation with clinical findings. MATERIALS AND METHODS: CT angiography (CTA) raw data of DAVF were used for multiplanar reconstruction and then analyzed for the presence and pattern of EMV, which is defined as a dilated vein in the cerebral white matter...

Central venous occlusion is conventionally managed with balloon angioplasty, stent extension or sharp recanalization. Here we describe recanalization of a chronically occluded innominate vein using excimer laser after conventional techniques were unsuccessful. Patient clinical improvement and fistula patency have been sustained two years post-intervention. This technique may provide new hemodialysis access options for patients who would not otherwise be candidates for hemodialysis access on the ipsilateral side of a central venous occlusion...

Arteriovenous malformations consist of tangles of arteries and veins that are often connected by a fistula. The causes and mechanisms of these clinical entities are not fully understood. We discovered that suturing an arterial patch into the common jugular vein of rabbits led to spontaneous neovascularization, the formation of an arteriovenous fistula and the development of an arteriovenous shunt. An arterial patch excised from the common carotid artery was sutured into the common jugular vein. Within a month, a dense nidus-like neovasculature formed around the patch...

BACKGROUND: Duplex ultrasound (DUS) mapping of the veins and arteries of the upper extremity is a well-established practice in arteriovenous fistula creation for long-term hemodialysis access. Previous publications have shown that vein diameters varying from 2 to 3 mm are predictive of success. Regional anesthesia is known to result in vasodilation and thus to increase the diameter of upper extremity veins. This study compares the sizes of veins measured by preoperative DUS mapping with those obtained after regional anesthesia to determine whether intraoperative DUS results in increased vein diameters and thus changes in the operative plan...

Chronic kidney disease (CKD) is associated with an imbalanced human microbiome due not only to CKD-associated factors such as uremia, increased inflammation and immunosuppression, but also to pharmacological therapies and dietary restrictions. End-stage renal disease patients require renal replacement therapies commonly in the form of hemodialysis (HD) or peritoneal dialysis (PD). HD implies the existence of a vascular access, such as an arteriovenous fistula/graft or a venous catheter, whereas PD implies a long-term peritoneal catheter and the constant inflow of peritoneal dialysate...

REVIEW
Tina S Ipe, Marisa B Marques
Therapeutic plasma exchange is an apheresis modality in which plasma is separated from the blood cellular components ex vivo, discarded, and replaced with an isosmotic fluid (most commonly 5% albumin) to maintain appropriate oncotic pressure in the patient. Therapeutic plasma exchange is used in the treatment of many diseases and indications. The recent seventh edition of the American Society for Apheresis guidelines indicates approximately 72 diseases and 116 indications for which therapeutic plasma exchange may be effective...

Internal carotid arterial system is the main source of blood supply in brain. In forensic identification practice, blunt injures of internal carotid arterial system usually cause complications such as thrombus, aneurysm and arteriovenous fistula, etc. The deaths following delayed cerebral infarction or intracranial haemorrhage are not rare. At present, literature of deaths caused by blunt injuries of internal carotid arterial system mainly consist of case reports in China. This paper reviews related literature and case reports at home and abroad, and summarizes forensic medical features and identification method of the deaths caused by such injuries...

In addition to haematoma and arteriovenous fistula, the iatrogenic pseudoaneurysm is a common complication of vascular access that is caused by a perforation in the arterial wall. Iatrogenic pseudoaneurysms can progress in size and lead to rupture and active bleeding. Over the previous few decades, therapeutic methods have evolved from surgical repair to less invasive options, such as ultrasound-guided compression therapy (UGCT) and ultrasound-guided thrombin injection (UGTI). This paper presents an overview of the diagnostic and treatment modalities used in femoral pseudoaneurysms as well as a comprehensive summary of previous studies that analysed the success and complication rates of UGCT and UGTI...

Tinnitus is the perception of sound in the absence of a corresponding external acoustic stimulus, resulting in an estimated prevalence of 10% to 15% in adults. Tinnitus may be classified as pulsatile (PT) or continuous (non-PT), and may be subjective (heard only by the patient) or objective (also audible to the examiner). PT is usually related to vascular causes and is pulse synchronous (coinciding with the patient's heartbeat). PT is much less common affecting approximately 4% of patients with tinnitus, but unlike non-PT, usually has a specific identifiable cause...
