OBJECTIVE: Venous aneurysms are uncommon vascular abnormalities that may be identified anywhere in the body. Historically, they were often misdiagnosed as soft tissue lesions, but with the advent of readily available noninvasive imaging (such as duplex ultrasound), they can now be easily identified. Our aim was to review the presentation of venous aneurysms, available imaging modalities for defining them, and management. METHODS: The English-language literature before March 2017 was reviewed, and only reports of primary venous aneurysms of the deep veins were included...

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...

Synovial Chondromatosis (SC) is a rare, benign synovial growth most frequently involving the knee or hip joint. Common presenting symptoms include pain throughout the affected joint, reduced range of motion and a palpable mass. We present an unusual case of SC presenting with symptoms of chronic venous stasis ulcer. A 49-year-old patient presented with swelling, hyperpigmentation and ulcerations of his right lower extremity. Work-up including duplex and CT scan revealed a calcified mass in the hip joint, highly suspicious for Synovial Chondromatosis...

INTRODUCTION: Diagnosis of endoleaks is imperative to prevent failure of endovascular aneurysm repairs (EVARs). The gold standard for diagnosis of endoleaks is catheter-directed subtraction angiography, which is not a practicable choice for surveillance. CT angiography (CTA) is the historical surveillance modality of choice. Concerns over cost, potential nephrotoxicity of contrast agents and repeated radiation exposure led to colour duplex ultrasound scan (CDUS) becoming an established alternative...

INTRODUCTION: Simultaneous kidney and pancreas transplant is the preferred treatment option for end-stage renal disease due to type 1 diabetic nephropathy. Vascular complications are detrimental to graft survival and can lead to graft loss in the early postoperative phase of transplantation. Generally, duplex Doppler ultrasound is used for vascular patency monitoring and pancreatectomy followed by re-transplantation is required in the majority of cases. Recently, pancreatic graft salvage with non-operative management, including medical anticoagulation and endovascular thrombectomy, in the early postoperative period has been described with success...

The relationship between the results of penile duplex Doppler ultrasound (PDDU) and response to vardenafil was investigated in patients diagnosed with erectile dysfunction (ED). Data from 148 patients with ED were analyzed retrospectively. Patients who did not respond to therapy were classified in to Group I ( n = 32), those who responded partially were classified into Group II ( n = 40), and complete responders were classified into Group III ( n = 76). Age, comorbidities, and vascular and penile pathologies were compared among the three groups...

AIM: Malignancy is common in patients presenting with critical lower limb ischemia (CLI). However, outcomes in patients with concomitant active malignancy and CLI have not been well defined in comparative prospective analyses. Using contemporary prospective data, we aimed to assess outcomes following revascularization in patients with CLI and active malignancy. METHODS: A nested case-control study was performed using data from 2 tertiary referral centers for vascular disease...

Introduction The free jejunal flap represents the gold standard for circumferential defects in upper digestive tract reconstruction. It is a technically demanding procedure with significant failure rates. Unrecognised failure leads to flap necrosis and potentially fatal sequelae, including sepsis and carotid artery bleed. Despite these catastrophic consequences, however, there remains no consensus on an optimum method for postoperative flap monitoring. Our unit has pioneered the use of external colour duplex ultrasound to monitor flap vascularity...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

OBJECTIVE: The ankle-brachial index (ABI) is a well-established measure of distal perfusion in lower extremity ischemia; however, the ABI is of limited value in patients with noncompressible lower extremity arteries. We sought to demonstrate whether duplex ultrasound-determined tibial artery velocities can be used as an alternative to ABI as an objective performance measure after endovascular treatment of above-knee arterial stenosis. METHODS: Thirty-six patients undergoing above-knee endovascular intervention had preprocedure and postprocedure duplex ultrasound examination within 6 months of intervention...

PURPOSE: Primary arteriovenous fistula arterio venous fistula (AVF) formation has proven to be the best and optimal vascular access for the majority of haemodialysis patients. At present there are limited data to suggest which haemodynamic parameters most correlate with the likelihood of early failure. The aim of this study is to identify the haemodynamic predictors of early failure, hence identify which fistulae may benefit from timely pre-emptive intervention. MATERIAL AND METHODS: Retrospective analysis of data was performed of 201 patients undergoing native AVF creation over a one year period...

African horse sickness (AHS) is a fatal vector transmitted viral disease of horses caused by the African horse sickness virus (AHSV). This disease is characterised by circulatory and respiratory failure, resulting from vascular endothelial injury affecting many organs. The susceptibility of dogs to AHS has been demonstrated in the past following experimental infection through consumption of infected horse meat. clinical cases of AHS in dogs (cAHS) have been documented, without a history of ingesting infected horse meat, over a period of 12 years...

Radiocephalic arteriovenous fistula (RCAVF) is the first choice for native arteriovenous fistula (AVF). Preoperative vessel assessment with ultrasonography (USG) has been reported to enhance the outcome of native AVF, but data regarding its predictive value for functional maturation of RCAVF are scanty. We aimed to determine the role of preoperative duplex USG (DUS) for prediction of functional maturity of radiocephalic fistula in the wrist. The data from 173 patients were analyzed prospectively. The estimated duplex variable included size, patency, and continuity of cephalic vein and size, peak systolic velocity, and wall calcifications in radial artery at the wrist...

The decision to intervene for internal carotid stenosis often depends on the degree of stenosis seen on duplex ultrasound (US). The aim of this study is to compare the diagnostic accuracy of two criteria: modified University of Washington (UW) and 2003 Carotid Consensus Panel (CCP). All patients undergoing US in an accredited (IAC) vascular laboratory from January 2010 to June 2015 were reviewed ( n=18,772 US exams). Patients receiving a neck computed tomography angiography (CTA) within 6 months of the US were included in the study ( n=254)...

A 41-year-old woman presented with a large painful and tender mass of the left side of her neck located just below the angle of the mandible. She was also complaining of frequent attacks of symptoms ranging from dizziness upon resuming the erect position to frank syncope. Color-coded duplex showed a large well-vascularized vascular mass at the level of the carotid bifurcation, suggesting the diagnosis of a carotid body tumor (CBT). A computerized tomographic angiography confirmed the diagnosis of a CBT, which measured 5...

INTRODUCTION: Proximity Extension Assay (PEA) is a direct one-step protein quantification method using a pair of DNA oligonucleotides linked to antibodies against the target molecule. It requires polyclonal or two monoclonal antibodies (mAbs) that bind to target epitopes close enough to form a DNA duplex which is quantified by real-time PCR. Bevacizumab, an anti-cancer drug, is a mAb against vascular endothelial growth factor with common cardiovascular adverse effects. It is widely used off-label to treat neovascular eye disorders by intravitreal application of small doses...
