Decellularization of human iliac artery: A vascular scaffold for peripheral repairs with human mesenchymal cells.

This work presents strong evidence supporting the use of decellularized human iliac arteries combined with adipose tissue-derived stem cells (hASCs) as a promising alternative for vascular tissue engineering, opening the path to future treatments for peripheral artery disease (PAD). PAD is a progressive condition with high rates of amputation and mortality due to ischemic damage and limited graft options. Traditional synthetic grafts often fail due to poor integration, while autologous grafts may be unsuitable for patients with compromised vascular health.

Material And Methods: Retrospective, cross-sectional, observational study, in which mortality and hospitalization attributed to aortic aneurysms and dissections were analyzed.

Retrocarotid dissection technique compared to the caudocranial approach for the surgical treatment of carotid body tumors: A 15-year experience.

Introduction: Carotid body tumors are rare neoplasms with malignant potential. We aim to follow up on our initial experience published in 2015 and compare the occurrence of complications and postoperative outcomes with the use of retrocarotid dissection (RCD) against the standard caudocranial (SCCD) technique.

Methods: This was an observational, case-control study in which we analyzed all of the carotid body tumor resections performed from 1986 to 2022.

Takayasu's Arteritis in Mexican Monozygotic Twins: Analysis of Human Leukocyte Antigens (HLA) Haplotypes.

Takayasu's arteritis (TA) is an idiopathic great vessel vasculitis that affects the aorta and its branches. This entity is associated with the major histocompatibility complex (MHC) genes. We studied DNA sequences of human leukocyte antigens (HLA) haplotypes in one pair of Mexican monozygotic twins affected by TA.

The effect of cilostazol on the platelet-derived growth factor-beta/beta isoform reduction on venous hyperplasia in an experimental balloon-induced injury model.

Background: Intimal hyperplasia is the response to endothelial injury. Platelet-derived growth factor is released early and favors the formation of intimal hyperplasia. Although multiple treatments, from open surgery to endovascular techniques, have been used they remain controversial.

Five-year survival after retroperitoneal oncologic resection with and without vascular surgeon intervention.

Objectives: Retroperitoneal tumor resection commonly disturbs major vessels; therefore, surgical teams can recruit vascular surgeons to prevent injuries and improve the prognosis of oncologic patients. The objective of the present study is to establish long-term survival after retroperitoneal tumor resection surgery with an emphasis on the potential impact of preventing or repairing major vessel injuries when tumors are adjacent to the aorta or vena cava.

Methods: Retrospective case series including all cases of surgical removal of retroperitoneal tumors between 2007 and 2020 in a highly specialized hospital in Mexico City.

The Effects of COVID-19 on Healthcare Workers and Non-Healthcare Workers in Mexico: 14 Months into the Pandemic.

Healthcare workers (HCWs) play important roles in mitigating the COVID-19 pandemic and are more likely to become infected with COVID-19. Mexico, among other countries, had a high incidence and prevalence of cases and deaths from this disease. This retrospective study evaluated the clinical characteristics as well as the geographical distribution of cases, deaths, and active cases of COVID-19 in HCWs and non-HCWs using official information from the Ministry of Health of Mexico.

Cilostazol as a noninferiority pharmacologic option to paclitaxel in early intimal hyperplasia inhibition after venous balloon angioplasty in a rabbit model: a preliminary study.

Unlabelled: The development of venous intimal hyperplasia (VIH) has not been fully studied. At present, there are no drugs approved for VIH inhibition; to investigate such alternatives, we aimed to compare paclitaxel with cilostazol in VIH early inhibition in a preliminary experimental model of balloon angioplasty. Twenty-eight male New Zealand rabbits were randomly divided into two groups: cilostazol (A) and paclitaxel (B), which underwent femoral vein barotrauma by a 4 mm balloon angioplasty.

Surgical Management of a Type II Extracranial Internal Carotid Aneurysm near to the Skull Base.

True aneurysmal disease in the carotid arteries is very uncommon, but individuals with this pathology face the grave risk of thromboembolism, which may consequently lead to cerebrovascular accidents. Clinical knowledge remains relatively limited owing to its rarity. We present the case of a 41-year-old obese female with a type II right extracranial internal carotid artery aneurysm incidentally found during imaging work-up.

Favorable Conservative Management of a Rare Primary Aortitis Secondary to Listeria Monocytogenes: Case Report and Review of the Literature.

Primary aortitis (PA) secondary to Listeria monocytogenes is extremely rare with only a few cases reported in the literature. Presently, there is no consensus concerning the best treatment when no complications are found in the thoracic computed tomography (CT) imaging. This report illustrates the clinical presentation and favorable clinical course of a rare case of PA secondary to in an 82-year-old diabetic woman, successfully treated with conservative management with 18 months of follow up.

Physician-Modified Endovascular Gore Excluder Graft (Handmade Modified) for Complex Abdominal Aortic Aneurysm: A Step-by-Step Approach.

Endovascular repair has become the gold standard for the treatment of infrarenal abdominal aortic aneurysmal disease. Branched and fenestrated commercially custom-made devices have been developed as a treatment option for short necks or juxtarenal aneurysms. However, the lack of availability in some countries and centers, manufacturing time (6-8 weeks requirements), urgent setting in ruptured abdominal aortic aneurysms, and elevated costs make them not a widespread option.

Incidence of thrombotic events and complications associated to inferior vena cava filters in patients with and without anticoagulation therapy.

Objective: Anticoagulation is the primary management to prevent venous thromboembolism; inferior vena cava filters (IVCFs) provide a mechanical prophylactic alternative when anticoagulation is contraindicated. The aim of this study was to evaluate in IVCF patients, whether the initiation of anticoagulation therapy is associated with decreased rates of recurrent thrombotic events and device-related complications.

Methods: This was a retrospective review of patients that underwent insertion of IVCF.

Successful Treatment of a Superficial Femoral Artery Pseudoaneurysm with Balloon Tamponade.

The development of post-catheterization arterial pseudoaneurysms is one of the most common vascular access complications following angiographies and endovascular interventions. Different therapeutic options to treat these lesions have been used. We herein report the case of a 79-year-old woman who was referred to our service for evaluation with a post-catheterization superficial femoral artery pseudoaneurysm measuring 4 cm.

Usefulness of preoperative three-dimensional volumetric analysis of carotid body tumors.

Purpose: The Shamblin classification is the commonest method to predict complications and outcomes during carotid body tumor (CBT) resection. The aim of this study is to describe the utility of the three-dimensional volumetric reconstruction (3DVR) analysis of the CBT and its relationship with postoperative outcomes.

Methods: Preoperative computed tomography angiography (CTA) was obtained to perform 3DVR of the CBT.

Carotid body tumors are rare neoplasms with malignant potential in 6% to 12.5% of cases, and surgical resection is the only cure. We present the cases of 2 female patients who had expanding, painless, right-sided neck masses; computed tomographic angiograms revealed Shamblin III tumors at the carotid bifurcation.
