BACKGROUND: Wasp stings are commonly encountered worldwide and result in a variety of clinical manifestations including local and systemic reactions. Neurological and vascular complications are rarely reported following a wasp sting. CASE PRESENTATION: A 69-year-old Sri Lankan Tamil man presented to our hospital with focal neurological deficit following multiple wasp stings; the deficit was confirmed to be an acute infarction on magnetic resonance imaging scan. He was screened for metabolic risk factors which were negative and he had a normal two-dimensional echocardiogram and normal carotid arteries in carotid duplex which excluded potential sources of thromboembolism...

OBJECTIVES: To test a novel diagnostic technique to assess radial artery perfusion after transradial catheterization. BACKGROUND: Despite being mostly asymptomatic, radial artery occlusion (RAO) is not a benign complication, and its diagnosis is frequently missed because it requires time-consuming diagnostic testing. We developed a novel operator-independent diagnostic test to assess RAO after coronary procedures through a transradial access (TRA) by means of hand Laser Perfusion Imaging (LPI)...

A 48-year-old woman presented with an acute ischemic stroke (National Institutes of Health Stroke Scale (NIHSS) 21) six hours after symptom onset. Workup revealed a left cervical internal carotid artery (ICA) occlusive dissection, which was emergently reconstructed with a flow-diverting stent. A routine Duplex scan one hour later suggested reocclusion of the ICA, confirmed by angiography. The true lumen of the ICA could not be accessed and therefore the "false lumen" of the ICA dissection was entered proximally...

Objective : Native fistula creation for hemodialysis in patients who have exhausted all their superficial veins presents a challenge to vascular practice. We review our experience in transposed basilic vein fistula (BVT) creation and its usage for hemodialysis. Materials and Methods : We analyzed the hospital operative registry from January 2009 till June 2012 to identify the total number of BVT created in our center. Medical records of all patients were traced, and patients were interviewed using a standard proforma...

Rosai-Dorfman (-Destombes) disease (RDDD) is a rare idiopathic disorder of histiocyte proliferation, usually involving lymph node stations. The most common clinical finding is a bilateral cervical lymphadenopathy, fever, and weight loss. Arterial or venous structures are notably not involved. We hereby present a case of a 78-year-old Caucasian man, presenting with symptoms of progressive arterial insufficiency and right lower-limb edema, along with a nonpulsatile mass at the middle third of the thigh. Initial diagnostic hypothesis was a superficial femoral artery aneurysm thrombosis with a secondary postcompressive superficial femoral vein thrombosis...

OBJECTIVE: Surveillance techniques for arteriovenous fistulae are required to maintain functional vascular access, with two-dimensional duplex ultrasound the most widely used imaging modality. This paper presents a surveillance method for an arteriovenous fistula using a freehand three-dimensional (3-D) ultrasound system. A patient-case study highlights the applicability in a clinical environment. METHODS: The freehand ultrasound system uses optical tracking to determine the vascular probe location, and as the probe is swept down a patient's arm, each B-mode slice is spatially arranged to be post-processed as a volume...

We developed a duplex ultrasound simulator for training and assessment of scanning skills. We used the simulator to test examiner performance in the measurement of flow velocities in dialysis access fistulas. Test cases were created from 3-D ultrasound scans of two dialysis access fistulas by reconstructing 3-D blood vessel models and simulating blood flow velocity fields within the lumens. The simulator displays a 2-D B-mode or color Doppler image corresponding to transducer position on a mannequin; a spectral waveform is generated according to Doppler sample volume location and system settings...

INTRODUCTION: Median arcuate ligament syndrome (MALS) or Dunbar syndrome is a rare clinical entity characterized by celiac trunk compression by median arcuate ligament and variable gastrointestinal symptoms (postprandial epigastric pain, nausea, weight loss, anorexia and diarrhea). However, some degree of radiographic compression is observed in 10%-24% of asymptomatic patients. Besides the extrinsic vascular compression, MALS has a multifactorial etiology and it has been suggested as a neurogenic disease resulting in altered sensation and pain from the somatic nerves in the splanchnic plexus...

BACKGROUND: Common femoral artery is still the most frequently used site for vascular access, mostly for peripheral arterial interventions, and its puncture remains a significant source of patient's morbidity. Manual compression (MC) has been the gold standard for hemostasis after femoral catheterization until recently, but only in the last few years, vascular closure devices (VCDs) are replacing MC due to their rapid development. Nowadays, vascular surgeons (VSs) are also becoming familiar with VCDs...

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 computed tomography scan revealed a calcified mass in the hip joint, highly suspicious for SC...

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...
