INTRODUCTION: Popliteal artery aneurysms (PAA) are the most prevalent form of peripheral arterial aneurysms. Greater saphenous vein grafts and endoaneurysmorrhaphy remains the mainstay therapy for open repair of PAA. True aneurysmal degeneration of lower extremity infrainguinal autologous vein grafts are relatively rare and its etiology is not completely understood. CASE PRESENTATION: We present a case of a 57-year-old man with recurrent autologous venous graft aneurysmal dilatations following a surgical popliteal artery aneurysm repair...

Complement activation, specifically complement 3 (C3) activation and C3a generation, contributes to an imbalance between angiogenic stimulation by vascular endothelial growth factor (VEGF) and angiogenic inhibition by pigment epithelial derived factor (PEDF), leading to pathological angiogenesis. This study aimed to investigate the effects of C3a and small interfering RNA (siRNA) targeting C3 on the levels of VEGF and PEDF mRNAs in human retinal pigment epithelial (RPE) cells. ARPE-19 cells were cultured in the presence of exogenous C3a at 0...

OBJECTIVE: In patients with a high risk of fistula immaturity, we created arteriovenous fistulas (AVFs) combined with brachial artery superficialization. With this procedure, the superficialized arteries are used as drawing routes and the AVFs as returning routes. This is a technical report about AVFs combined with brachial artery superficialization. METHODS: Twenty-four consecutive patients with a high risk of fistula immaturity who underwent AVFs with brachial artery superficialization were included in this single-center retrospective study...

OBJECTIVE: To determine if duplex ultrasound (US) for arteriovenous fistulas (AVFs) can predict vascular events (VEs; thrombosis and stenosis). METHODS: Duplex US was performed for vascular access evaluation in 2557 maintenance hemodialysis (HD) patients between October 1, 2013 and March 31, 2016. Of these patients, 2184 patients were finally included in this study. AVF dysfunction was assessed using the brachial artery blood flow volume (Qa; mL/min), arterial blood flow resistance index (RI), and residual diameter of the fistula vein (RD; mm)...

OBJECTIVES: In 2013 the International Society for Sexual Medicine(ISSM) published the guidelines regarding the standard operating procedure (SOP) for penile duplex Doppler ultrasound (PDDU). Although ISSM-SOP have given important strides in reducing interobserver variability in PDDU by procedural protocol and parameters these guidelines do not address the anatomic location along the penis at which hemodynamic measurements have to be done. In our opinion a "double sampling" may be interesting to detect the arteriogenic or venogenic nature of the erectile dysfunction (ED)...

OBJECTIVE/BACKGROUND: Hemodynamic measurements of blood flow in the common femoral vein and artery can be performed readily using duplex sonography. The ratio of venous to arterial volume flow in these vessels, the venous arterial flow index (VAFI), is increased in patients with varicose veins and/or chronic venous disease. The objective was to determine the reproducibility of sonographically measured hemodynamic flow parameters using phase contrast magnetic resonance imaging (MRI). METHODS: Based on hemodynamic volume flow measurements from the common femoral vein and artery the VAFI was calculated in seven patients with varicose veins (C2, Ep, As, Pr) and 32 healthy controls using standard duplex sonography and MRI...

Adventitial cystic disease (ACD) of the common femoral vein is a rare vascular disorder. It becomes more difficult to recognize preoperatively especially when the femoral vein is affected. We report the case of a 62-year-old female patient who presented with a one-month history of painless swelling in her right lower extremity. She had no specific past medical history and no history of trauma, and had a full coagulopathy profile that was negative for any hypercoagulable syndrome. On examination, her lower right leg was significantly swollen with a palpable mass in her right inguinal region...

The use of ultrasonography and especially of contrast-enhanced ultrasonography (CEUS) in the diagnosis of vascular pathologies before and after interventions has significantly increased over the past years due to the broader availability of modern ultrasound systems with CEUS capabilities and more trained user experience in this imaging modality. For the preinterventional and postinterventional work-up of carotid diseases, duplex ultrasound as well as CEUS have been established as the standard-of-care examination procedures for diagnosis, evaluation, and follow-up...

PURPOSE: To report the results of percutaneous endovascular aortic aneurysm repair (PEVAR) using the superficial femoral artery (SFA) for large-bore vessel access. METHODS: We reviewed all PEVAR procedures at our institution over an 18-month period, identifying all patients who underwent PEVAR with the use of one or both SFAs for endograft delivery with dual ProGlide large-bore access closure. Indications for use of the SFA instead of the common femoral artery (CFA) included morbid obesity, CFA vessel wall disease, and scarring from previous CFA surgery...

INTRODUCTION AND OBJECTIVES: The gold standard for the diagnosis of lower extremity deep vein thrombosis (DVT) is reported to be venous duplex ultrasound (VDU) because it is noninvasive, sensitive, relatively inexpensive, and can be performed at a patients bedside. The objective of this investigation was to measure agreement in the interpretation of VDU between multiple medical specialties. METHODS: Agreement among different physicians who typically interpret VDU images were examined...

BACKGROUND: The use of autologous superficial femoral veins (SFV) as an arterial or venous substitute represents a valuable technique in modern vascular surgery with versatile indications. The SFV autografts exhibit excellent control of infection and durable long-term results in terms of graft patency in prosthetic or arterial infections. In cases of elective use of the SFV, duplex ultrasound evaluation of the deep leg vein system should be implemented to confirm the patency of the profunda femoris vein...

BACKGROUND: Accreditation in peripheral venous testing can be obtained based upon femoropopliteal duplex ultrasound evaluation, and many laboratories limit their examination to this segment only. This simplified protocol detects acute femoropopliteal deep venous thrombosis (DVT) but misses calf vein DVT, superficial venous thrombosis, chronic DVT, venous reflux, and other non-venous findings potentially responsible of the patients' presenting conditions. A protocol limited to the femoropopliteal segment results in additional unnecessary testing and can create patient dissatisfaction...
