Swaminathan Sundaresan, Michael R Migden, Sirunya Silapunt
Stasis dermatitis commonly occurs in older age. It is caused by venous hypertension resulting from retrograde flow due to incompetent venous valves, valve destruction, or obstruction of the venous system. Further tissue changes arise from an inflammatory process mediated by metalloproteinases, which are up-regulated by ferric ion from extravasated red blood cells. Stasis dermatitis presents initially as poorly demarcated erythematous plaques of the lower legs bilaterally, classically involving the medial malleolus...

We present three cases of anomalous origin of the left vertebral artery (LVA) detected during the evaluation of stroke. The VA usually enters the transverse foramen of the sixth cervical vertebra (C6), but an anomalous LVA originating from the aorta frequently enters at a higher level. In our series, ultrasound of the LVA showed entry at C4 in two patients and at C5 in one patient. These findings suggested anomalous LVA origin, and three-dimensional computed tomography demonstrated the LVA arising from the aorta proximal to the left subclavian arteries...

BACKGROUND: Currently, colour-coded duplex sonography (2D-CDS) is clinical standard for detection and grading of internal carotid artery stenosis (ICAS). However, unlike angiographic imaging modalities, 2D-CDS assesses ICAS by its hemodynamic effects rather than luminal changes. Aim of this study was to evaluate freehand 3D ultrasound (3DUS) for direct visualisation and quantification of ICAS. METHODS: Thirty-seven patients with 43 ICAS were examined with 2D-CDS as reference standard and with freehand B-mode respectively power-mode 3DUS...

We present a patient with a 16 cm adrenocortical carcinoma that underwent a left adrenalectomy en bloc with resection of the involved segment of the left renal artery. A splenectomy and splenorenal bypass was performed to revascularize the left kidney. To our knowledge, this is the first instance in the literature of a splenorenal arterial bypass being reported for renal revascularization during an extirpative oncologic procedure. A 64-year-old male patient, with history significant for adrenocortical carcinoma, status post prior right adrenalectomy with partial right nephrectomy, presented for an elective left adrenalectomy...

Although there is limited evidence that antepartum testing decreases the risk for fetal death in low-risk pregnancies, women with high-risk factors for stillbirth should undergo antenatal fetal surveillance. The strongest evidence supporting antepartum testing pertains to pregnancies complicated by intrauterine fetal growth restriction secondary to uteroplacental insufficiency. The main ultrasound-based modalities to determine fetal health are the biophysical profile, modified biophysical profile, and duplex Doppler velocimetry...

BACKGROUND: Three-dimensional contrast-enhanced ultrasound (3D-CEUS) is a novel technology allowing surgeons to view duplex ultrasound images in three dimensions with ultrasound contrast highlighting blood flow in endoleaks after endovascular aneurysm repair (EVAR). It potentially reduces the need for computed tomography angiography (CTA) and catheter angiography. This study compares 3D-CEUS with both CTA and the final vascular multidisciplinary team (MDT) diagnosis using all available imaging...

We report a modified operative technique termed partial eversion carotid endarterectomy (PECE). During a 9-year period (2006-2015), 352 patients underwent PECE. Indications for surgery, intraoperative details, and outcomes were recorded. The initial 185 patients had carotid duplex ultrasound imaging at 6 weeks and then at 6, 12, and 24 months. Subsequent patients had carotid imaging at 4 to 6 weeks. Indications included stroke (76), transient ischemic attack (153), and amaurosis fugax (33); 58 patients were asymptomatic, and 32 patients had surgery before cardiac surgery...

False aneurysms are formed as a result of bleeding causing a hematoma to compress the surrounding tissue. The majority of false aneurysms presenting to the vascular surgeon are caused by iatrogenic injury to an artery. Although anastomotic failure occurs, a much higher number is caused by bleeding from puncture sites after percutaeous intervention. Anticoagulative medication, low patelet counts and severely calcified vessels increase the risk of forming a false aneurysm. Experienced specialists may make the diagnosis from physical examination, but ultrasound imaging is almost always needed in order to decide for a treatment strategy...

Passive heat induces beneficial perfusion profiles, provides substantive cardiovascular strain and reduces blood pressure, thereby holding potential for healthy and cardiovascular disease populations. The aim of this study was to assess acute responses to passive heat via lower-limb hot-water immersion in patients with peripheral arterial disease (PAD) and healthy, elderly controls. Eleven patients with PAD (age 71±6 y, 7 male) and ten Controls (age 72±7 y, 8 male) underwent hot-water immersion (30 min waist-level immersion in 42...

Despite advances in endovascular strategies, surgical infrainguinal lower limb revascularization remains the gold standard treatment for critical lower limb ischemia and disabling claudication.1 Maintaining patency of infrainguinal vein bypass grafts has been a challenging task for vascular surgeons as they are prone to developing stenosis which may precipitate failure of the bypass.2,3 Duplex ultrasound scanning has evolved as the investigation of choice to identify vein graft lesions but graft surveillance programs using this technique remain controversial...

OBJECTIVES: Pelvic congestion syndrome (PCS) is associated with pelvic vein reflux (PVR), occasionally secondary to venous compression. Its symptoms, usually intra-pelvic, are alleviated following the abolition of this reflux by pelvic vein embolisation (PVE). The objective of this report is to present two cases of left hip pain, erroneously diagnosed as osteoarthritis, which disappeared after successful PVE and abolition of PVR. METHODS: Two females presented with lower limb varicose veins, and also had a history of left-sided hip pain...
