Strong to moderate vascular endothelial growth factor (VEGF) expression may be a negative prognostic factor in canine mast cell tumors (MCTs). This study set out to determine the prognostic value of combined analysis of VEGF-A immunoreactivity, clinical presentation, patient staging, and tumor histologic grade in canine MCTs. In this study, intense VEGF staining was significantly associated with decreased survival (P = .025). Immunohistochemical expression of VEGF is not routinely employed as a prognostic factor in canine MCT workup. However, results of this study support the inclusion of this marker in the MCT prognostic panel. Investigation of VEGF expression may assist in the development of anti-VEGF drugs.
Given the superior patency of arteriovenous fistulas (AVFs) and the decreased risk of infection compared with arteriovenous grafts, the Kidney Disease Outcomes Quality Initiative guidelines have recommended the fistula-first approach. However, ∼20% to 60% of all fistulas will fail to mature. We have described our experience with a novel technique using bovine pericardial patch angioplasty to increase the rate of AVF maturation.

We used 2-cm×9-cm-long or 2.5-cm×15-cm-long segment pericardial patch angioplasty to assist in the maturation of AVFs. A single-center, retrospective cohort study was conducted of all patients who had undergone patch angioplasty maturation (PAM) for AVFs that had failed to mature. The outcomes of interest were maturation status and patency, censored by the death and last known follow-up dates.

From March 2007 to October 2019, 139 patients had undergone PAM. Follow-up data were available for 137 of the 139 patients (98.6%), with 126 AVFs (92.0%) progressing to maturation. this website Of the 1ng AVFs.
Long-segment bovine pericardial PAM can be performed safely to treat nonmaturing AVFs, with a 92.0% successful maturation rate and patency rates comparable to those for AVFs. PAM should be a consideration for patients with nonmaturing AVFs.
We evaluated the outcomes and complications of transcarotid artery revascularization (TCAR) outside of academic vascular surgery programs.

An institutional review board-approved retrospective study was performed. Data from all cases of TCAR performed at a community hospital from May 2017 to February 2020 were collected and analyzed. Seven vascular surgeons performed the procedures after receiving appropriate training. The primary outcomes included technical success, the need for further revascularization, and major adverse events (death, cerebrovascular accident [CVA], myocardial infarction). The secondary outcomes included other adverse events and complications. The outcomes were assessed in the perioperative and 30-day follow-up periods.

During a 33-month period, TCAR was completed in 147 of 149 attempted cases (98.7%). No patients required further revascularization. The perioperative and 30-day major adverse event rates were 0.7% (n= 1) and 3.4% (n= 5), respectively. One case of a minor perioperative CVA occurred. At 30days, one patient had died. The 30-day complications included CVA (n= 1) and myocardial infarction (n= 3). The combined perioperative and 30-day minor complication rates were 2.7% and 1.4%, respectively.

TCAR is a safe and effective method of carotid artery revascularization in a community hospital setting. This technology might help improve revascularization in patients without access to larger academic centers.

Management of the pandemic caused by the novel coronavirus SARS-CoV-2 challenges both scientists and physicians to rapidly develop, and urgently assess, effective diagnostic tests and therapeutic interventions. The initial presentation of the disease in symptomatic patients is invariably respiratory, with dry cough being the main symptom, but an increasing number of reports reveal multiple-organ involvement. The aim of this review is to summarize the potential role of the renin-angiotensin system activated phagocytes in the pathogenesis of COVID-19 disease.

Data for this review were identified by searches of PubMed and references from relevant articles using the search terms "SARS," "COVID-19," "renin-angiotensin-system," "phagocyte," "reactive free radical," "antioxidant," "ARDS," "thrombosis," "myocardial," "ischaemia," "reperfusion," "microvascular," and "ACE2." Abstracts and reports from meetings were not included in this work. Only articles published in English between 1976 and 2020 were reviewed.

The cellular target of SARS viruses is the angiotensin-converting enzyme 2, a critical regulating protein in the renin-angiotensin system. The elimination of this enzyme by the viral spike protein results in excessive activation of phagocytes, migration into the tissues via the high endothelial venules, and an oxidative burst. In the case of an overstimulated host immune response, not only devastating respiratory symptoms but even systemic or multiorgan involvement may be observed.

Early-stage medical interventions may assist in returning the exaggerated immune response to a normal range; however, some therapeutic delay might result in excessive tissue damages, occasionally mimicking a systemic disease with a detrimental outcome.

The Anaconda stent graft device presents peculiar and unique features in its design and deployment sequence, available on the market for many years with minor modifications, among different generations. The aim of this study was to assess the long-term, real-life, outcomes obtained in two high-volume centers with this endograft for infrarenal aortic aneurysms treatment over a period of 19years.

All patients treated with the investigated device between 2000 and 2019, with at least 1year of follow-up, were entered into a prospective database and data were reviewed retrospectively. The long-term results were assessed according to the Kaplan-Meier method. Primary outcomes were overall survival, freedom from AAA rupture, and freedom from AAA-related death. Secondary outcomes were freedom from late reintervention, freedom from late conversion to open repair, freedom from late limb occlusion, and freedom from late EVAR failure.

A total of 260 consecutive patients were treated during the study period. Technical late AAA rupture or AAA related death in the studied population. Late limb occlusion was the leading cause of reintervention; however, a positive prevention strategy was found in intraoperative kissing balloon, which was associated with significant reduced rate of iliac thrombosis over time.

Different graft materials have been proposed for in situ reconstruction in the setting of vascular graft infection (VGI). We analyzed the long-term outcomes after in situ aortoiliac reconstruction with cryopreserved allografts.

We performed a retrospective analysis of patients who had undergone in situ aortoiliac reconstruction with cryopreserved arterial allografts for VGI from 2000 to 2015. The end points were the perioperative and long-term mortality and graft-related complications, including stenosis, occlusion, pseudoaneurysm, and reinfection.

A total of 33 patients (91% male) with a median age of 67years (range, 53-83years) had undergone in situ aortoiliac reconstruction with cryopreserved allografts. The 30-day mortality was 6% (n= 2); both deaths were related to the allograft (one early allograft-enteric fistula and one graft rupture). Another two patients had experienced early (≤30days) graft-related events (one allograft-enteric fistula and one graft limb occlusion), for an early graft-relatedlications were frequent in the long term, in particular, graft occlusion and stenosis.
In situ aortoiliac reconstruction with cryopreserved allografts to treat VGI was associated with relevant perioperative graft-related complications. Although the reinfection rate was acceptable, other graft-related complications were frequent in the long term, in particular, graft occlusion and stenosis.
Vascular graft infections are a serious complication in vascular surgery. Correct antibiotic therapy targeted to the most likely infecting species is essential to treat these patients, although the bacterial epidemiology and pathogenesis are still not completely understood. We analyzed the behavior of vascular graft infections and the microbiologic patterns of resistance.

A 10-year (2008-2018), single-center, retrospective cohort study was performed of all patients admitted with vascular graft infection identified by positive direct graft cultures. An extensive microbiologic study was performed to analyze the bacterial strains, antibiotic resistance and sensitivity, and prevalence stratified by the year.

A total of 72 vascular graft infections with positive graft cultures occurring in 65 patients were found. Their mean age was 67± 9.6years, and 85% were men. Infection-related mortality was 11%. Of the 65 patients, 14 had undergone aortobifemoral bypass, 13 axillofemoral bypass, 5 femorofemoral bypass, 2the study period with patterns similar to those for all nosocomial infections. This highlights the importance of studying the specific microbiology of each healthcare center and its relationship to vascular graft infections to achieve the best treatment possible.
The present study has shown that vascular graft infection microbiology changed in accordance with graft location and interval to infection from revascularization surgery and had also evolved over the study period with patterns similar to those for all nosocomial infections. This highlights the importance of studying the specific microbiology of each healthcare center and its relationship to vascular graft infections to achieve the best treatment possible.
Thoracic endovascular aortic repair (TEVAR) is an effective treatment of blunt thoracic aortic injury (BTAI). However, the risks and benefits of administering intraoperative heparin in trauma patients are not well-defined, especially with regard to bleeding complications.

The Vascular Quality Initiative registry was queried from 2013 to 2019 to identify patients who had undergone TEVAR for BTAI with or without the administration of intraoperative heparin. Univariate analyses were performed with the Student t test, Fisher exact test, or χ
test, as appropriate. Multivariable logistic regression was then performed to assess the association of heparin with inpatient mortality.

A total of 655 patients were included, of whom most had presented with grade III (53.3%) or IV (20%) BTAI. Patients receiving heparin were less likely to have an injury severity score (ISS) of ≥15 (70.2% vs 90.5%; P< .0001) or major head or neck injury (39.6% vs 62.9%; P< .0001). Patients receiving heparin also had a lower incidence of inpatient death (5.
