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...

The postexercise ankle-brachial index (ABI) is recommended in patients with normal resting ABI when peripheral artery disease (PAD) is suspected. The aims of this study were to determine the comparative diagnostic accuracy of the resting and postexercise ABI for detecting PAD, and, the effect of the presence of diabetes on these. Three methods of interpretation currently in use were also investigated: a reduction in postexercise ABI by >20% compared to resting ABI, an ABI value of ≤0.90 postexercise, or a reduction in systolic ankle pressure of >30 mmHg postexercise...

Cerebral artery stenosis (CAS) is the most important causes of ischaemic stroke. Lipoprotein-associated phospholipase A2 (Lp-PLA2) plays 2 diverse roles in atherosclerosis (pro-inflammatory and anti-inflammatory), and the association between Lp-PLA2 mass and cardiovascular or cerebrovascular events is inconsistent among previous studies. A cross-sectional study including 2012 North Chinese adults aged ≥40 years was performed in 2010-2011 to investigate whether Lp-PLA2 mass is associated with asymptomatic cerebral artery stenosis (ACAS)...

BACKGROUND: Right-sided subclavian artery stenosis is a rare cerebrovascular disease involving the upper extremities. Considering an endovascular approach for its management requires increased endovascular and catheterization skills, when compared to the left side, due to the close approximation of the right subclavian artery origin, vertebral and common carotid arteries. METHODS: Three patients suffering from proximal right sided subclavian artery stenosis were treated in our center through primary stenting...

Healthcare providers who use peripheral vascular and cardiac ultrasound require specialized training to develop the technical and interpretive skills necessary to perform accurate diagnostic tests. Assessment of competence is a critical component of training that documents a learner's progress and is a requirement for competency-based medical education (CBME) as well as specialty certification or credentialing. The use of simulation for CBME in diagnostic ultrasound is particularly appealing since it incorporates both the psychomotor and cognitive domains while eliminating dependency on the availability of live patients with a range of pathology...

OBJECTIVE: No standardized therapeutic algorithm or embolic agent of choice has yet been identified for management of congenital peripheral venous malformations (VMs). Treatment options and reported outcomes therefore vary widely. Herein, we present an institution-wide algorithm for management of symptomatic congenital peripheral VMs using a single embolotherapeutic modality. METHODS: During 36 months, patients with symptomatic congenital peripheral VMs underwent contrast-enhanced magnetic resonance imaging...

OBJECTIVE: Type II endoleaks (T2ELs) are commonly observed after endovascular aneurysm repair (EVAR). We sought to determine whether time at onset of T2ELs correlated with the need to intervene based on sac expansion or rupture. METHODS: Between 1998 and 2015, 462 EVARs performed at our institution had duplex ultrasound surveillance in our accredited noninvasive vascular laboratory. Computed tomography and arteriography were reserved for abnormal duplex ultrasound findings...

Femoral artery pseudoaneurysms are commonly iatrogenic due to increasing use of the artery for arterial interventions. Other reasons of pseudoaneurysm formation are intravenous drug use and penetrating trauma. Here, we have discussed the management strategy of a femoral artery pseuodoaneursym and the modalities for preventing the misdiagnoses of the pseudoaneurysm in the emergency department. A 50-year-old male patient was referred to our emergency department (ED) with claudication and severe local swelling...

Thoracic outlet syndrome (TOS) is a neurovascular condition involving the upper extremity, which is known to occur in individuals who perform chronic repetitive upper extremity activities. We prospectively evaluate the incidence of TOS in high-performance musicians who played bowed string musicians. Sixty-four high-performance string instrument musicians from orchestras and professional musical bands were included in the study. Fifty-two healthy volunteers formed an age-matched control group. Bilateral upper extremity duplex scanning for subclavian vessel compression was performed in all subjects...

BACKGROUND: Although only high-flow arteriovenous fistulas (AVFs) are postulated to cause high-output cardiac failure (HOCF), there are currently no universally accepted criteria defining a high-flow fistula. METHODS: To verify if vascular access blood flow (Qa) ≥ 2000 ml/min provides an accurate definition of high-flow fistula, we selected 29 consecutive patients with Qa ≥ 2000 ml/min at color-duplex ultrasound examination and assessed them for the presence of cardiac failure symptoms; transthoracic echocardiography was also performed...

REVIEW
Jaber Mustafa, Ilan Asher, Zev Sthoeger
Upper extremity deep vein thrombosis (UEDVT) is defined as thrombosis of the deep venous system (subclavian, axillary, brachial, ulnar, and radial veins), which drains the upper extremities. It can be caused by thoracic outlet anatomic obstruction, such as Paget-Schroetter syndrome, (primary) or by central intravenous catheters (secondary). UEDVT may be asymptomatic or present with acute severe pain and arm swelling. Clinical suspicion should be confirmed by diagnostic imaging procedures such as duplex ultrasound, computed tomography scan, or magnetic resonance imaging...

BACKGROUND: Perforator flaps have unique advantages that may overcome the shortcomings of conventional approaches to myelomeningocele reconstruction. However, identifying and dissecting tiny perforators in neonates is arduous. We have overcome these obstacles with a freestyle flap approach that uses duplex ultrasonography to locate perforator vessels, allowing for limited superficial dissection. This report describes the duplex ultrasonography-assisted freestyle pedicled perforator flap technique for closure of myelomeningocele defects, with long-term clinical outcomes...

Lower extremity deep vein thrombosis (DVT) is a frequent cause of admission to the emergency departments (ED). Although the gold standard for diagnosis is the Duplex ultrasound examination, the current study used for diagnosis of DVT in the ED by emergency physicians is the point-of-care compression ultrasound (POCUS). To compare the sensitivity and specificity of the two-point and three-point compression ultrasound (2PCUS and 3PCUS respectively) for diagnosis of lower extremity DVT in an ED management. We prospectively recruited outpatients who were admitted to the ED with suspected lower extremity DVT...

OBJECTIVE: Use of autologous veins as peripheral bypass graft may become critical in the presence of significant varicose degeneration of the harvested vein. External support of such dilated veins with standard polytetrafluoroethylene (PTFE) prostheses was recommended as an option to use these veins for peripheral bypass. A single-center experience with this technique regarding long-term graft function, secondary reinterventions, and potential graft degeneration is presented. METHODS: Between January 1995 and January 2006, there were 54 patients with varicose veins who underwent 57 consecutive infrainguinal vein bypass operations with PTFE reinforcement in 57 limbs...

OBJECTIVE: Because of advances in technology and experience of the operator, endovascular aneurysm repair (EVAR) has supplanted open repair to treat abdominal aortic aneurysm (AAA). The low 30-day mortality and morbidity of EVAR make the endovascular approach particularly suitable for patients at high surgical risk. However, endoleak or endograft migration requiring secondary intervention or open surgical conversion is a limitation of EVAR. The Nellix system (Endologix, Inc, Irvine, Calif) has been designed to seal the entire AAA to overcome these limitations with EVAR...
