Both open surgery and endovascular peripheral interventions have been shown to effectively improve outcomes in patients with peripheral arterial disease, but minimal data exist comparing outcomes performed at and below the knee. The purpose of this study was to compare outcomes following infrageniculate lower extremity open bypass (LEB) versus peripheral vascular intervention (PVI) in patients with critical limb ischemia. Using data from the 2008-2014 Vascular Quality Initiative, 1-year primary patency, major amputation, and mortality were compared among all patients undergoing LEB versus PVI at or below the knee for rest pain or tissue loss...

Operative mortality of Stanford type A aortic dissection( AAD) repair with previous cardiac surgery is high, especially with previous coronary artery bypass grafting. We report an extremely rare case of AAD related to the PAS-Port system. A 68-year-old male patient on dialysis was admitted to our hospital with a diagnosis of AAD. Half a year before he had undergone off-pump coronary artery bypass grafting using PAS-Port system for a proximal anastomosis of a vein graft. Urgent graft replacement of the ascending aorta was performed, and the proximal anastomotic site of the vein graft was attached to the prosthetic graft...

OBJECTIVE: Patients suffering blunt thoracic aortic injury (BTAI) can be treated by use of thoracic endovascular aortic repair (TEVAR). In this setting, the coverage of the left subclavian artery (LSA) is frequently necessary. Nevertheless, the functionality of the upper left extremity after TEVAR had been rarely analyzed. Thus this study intends to underline the safety of TEVAR as well as to determine the functionality of the left arm after coverage of the LSA. METHODS: All patients suffering from BTAI treated by endovascular means in three centers (Aachen [Germany], Maastricht [Netherlands] and Innsbruck [Austria]) between 1996 and 2009 were retrospectively analyzed...

OBJECTIVE: Current percutaneous thromboembolectomy techniques may obviate surgical intervention in high-risk patients with iliocaval thrombus or thrombus of the right side of the heart, but typically require thrombus fragmentation and thrombolysis with associated bleeding and thromboembolic complications. The AngioVac (Angiodynamics, Latham, NY USA) device uses a percutaneous venovenous bypass circuit to aspirate intact thrombus. A review of the literature was performed with regard to the AngioVac device to determine the factors correlating with successful thrombus extraction...

Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and/or pulmonary embolism (PE). Many surgeons and clinicians believe that VTE after coronary artery bypass grafting (CABG) has little clinical significance because it is seldom diagnosed. This study aimed to identify VTE after CABG, independent of clinical suspicion. In this prospective, observational, single-center study, 100 patients underwent computed tomographic pulmonary angiography (multidetector-64) and lower extremity venous compressive ultrasound after elective CABG...

BACKGROUND: Trocar site hernias (TSH) are reported in 0.3% to 5.4% of laparoscopic cases, depending on diameter and type. Most occur with trocars over 10 mm in diameter. Some recommend routine fascial closure, but this requires time, costs, pain, and increased infection rates. All prior series are based on clinical presentation alone. We examined the possibly underreported prevalence of asymptomatic TSH on postoperative computed tomography (CT) scans in a series of laparoscopic gastric bypass (LGBP) patients with unclosed port site fascia...

Testicular germ cell tumors (TGCTs) share germline ancestry but diverge phenotypically and clinically as seminoma (SE) and nonseminoma (NSE), the latter including the pluripotent embryonal carcinoma (EC) and its differentiated derivatives, teratoma (TE), yolk sac tumor (YST), and choriocarcinoma. Epigenomes from TGCTs may illuminate reprogramming in both normal development and testicular tumorigenesis. Herein we investigate pure-histological forms of 130 TGCTs for conserved and subtype-specific DNA methylation, including analysis of relatedness to pluripotent stem cell (ESC, iPSC), primordial germ cell (PGC), and differentiated somatic references...

The encounter of a nanodrop with a trench on a hysteresis-free surface is explored by many-body dissipative particle dynamics to show the effect of surface roughness on droplet wetting. A free nanodrop exhibits Brownian motion and the diffusivity decays exponentially with the liquid-solid contact area. In contrast, as the nanodrop sits on a trench, its random motion is constrained. Work must be done to overcome the energy barriers for the transition between free and trapped states. The potential energy landscape is thus constructed based on the force-displacement plot...

BACKGROUND: Doppler sonography is a type of sonography used for imaging the blood flow in the vessels and heart. This technique uses ultrasound waves with high frequency. In some patient candidates for venous graft, the identification of the suitable vein is not possible with clinical examination. OBJECTIVE: This study compared the effects of preoperative color Doppler sonography of lower extremity veins on the postoperative outcomes of saphenectomy. METHODS: This randomized clinical trial was conducted on 100 candidates of an off-pump coronary artery bypass graft (CABG) hospitalized in Afshar Hospital in Yazd in 2015...

Patients with end-stage renal disease (ESRD) who present with critical limb ischemia (CLI) have become an increasingly common and complex treatment problem for vascular surgeons. Dialysis patients have high short-term mortality rates regardless of whether revascularization is pursued. ESRD patients with CLI can be managed with: local wound care, endovascular or surgical revascularization, or amputation. Some patients may heal small foot wounds with local wound care alone, even if distal perfusion is marginal, as long as any infectious process has been controlled...

INTRODUCTION: Clinical information continues to be limited regarding changes in the temporal risk profile for readmissions during the initial postoperative year in vascular surgery patients. We set out to describe the associations between demographics, clinical outcomes, comorbidity indices, and hospital readmissions in a sample of patients undergoing common extremity revascularization or dialysis access (ERDA) procedures. We hypothesized that factors independently associated with readmission will evolve from "short-term" to "long-term" determinants at 30-, 180-, and 360-day postoperative cutoff points...
