Tumor ablation including carotid artery resection and simultaneous reconstruction: A retrospective study.

The study purpose is to review the surgical approach and evaluate the results in cases of head and neck malignancies with internal carotid artery invasion. The anatomical site of the primary tumor varied including a fixed massive metastatic neck disease of an occult intraoral carcinoma of the right tonsil, a recurrent metastatic neck tumor after laryngectomy for glottic primary carcinoma and a metastatic malignant melanoma of an unknown primary origin. In all cases carotid artery was invaded and therefore resected.

Methods: A multi-institutional Greek study of late ruptures after EVAR between 2008 - 2022 was performed.

Association of miRNA-145 Single Nucleotide Polymorphisms in Abdominal Aortic Aneurysms.

Background/aim: MicroRNAs (miRNAs) are non-coding RNA molecules that exert post-transcriptional gene expression regulation in response to cellular or environmental changes. Genetic variation affects their synthesis and cellular actions, and single nucleotide polymorphisms (SNPs) are one example of genetic variants studied in relation to various diseases. Literature indicates that the differentially expressed miRNA-145 in patients' serum is an essential biomarker for abdominal aortic aneurysm (AAA).

Paraoxonase-1 and Symptomatic Status in Carotid Artery Disease.

Background: Paraoxonase-1 (PON-1) is a high-density lipoprotein (HDL)-associated hydrolase that appears to have a protective action against atherosclerosis. The aim of our study is to identify whether PON-1 levels may be associated with the manifestation of symptoms in patients with carotid artery stenosis.

Methods: We studied all patients who underwent carotid endarterectomy in the Vascular Surgery Department of Laikon Hospital, Athens, Greece, from July 2012 to July 2014.

DAB2IP Expression in Abdominal Aortic Aneurysm: EZH2 and mir-363-3p as Potential Mediators.

Background/aim: Nine genetic loci have been associated with abdominal aortic aneurysm (AAA) susceptibility, including DAB2IP. This gene is playing a role in apoptosis, cell proliferation and epithelial-to-mesenchymal transition in cancers. This study aimed to elucidate the differential expression levels of DAB2IP in AAA tissues and investigate whether mir-363-3p and EZH2 can be considered as potential mediators of its expression.

Suitability study of current endovascular aortic repair devices based on real-life anatomic data.

Background: There are a number of stent-grafts in the market, designed to handle difficult anatomies during endovascular aortic repair. The aim of this study is to determine which stent-graft is the most appropriate to accommodate the majority of infra-renal aortic aneurysms cases. An additional aim is to determine what stent-graft characteristics influence the suitability of the stent-graft.

Open repair of thoracoabdominal aortic aneurysms in experienced centers.

Objective: We performed a systematic review and meta-analysis aiming to assess the mortality and morbidity of all published case series on thoracoabdominal aortic aneurysms (TAAAs) in experienced centers treated with open repair.

Methods: A systematic search of the literature published until April 2017 was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Separate meta-analyses were conducted for overall in-hospital mortality for TAAA, mortality according to the type of TAAA, spinal cord ischemia, paraplegia and paraparesis, cardiac events, stroke, acute kidney failure, and bowel ischemia.

Aortocaval fistula: an unusual complication of ruptured abdominal aortic aneurysm.

Aortocaval fistula (ACF) is a rare complication of abdominal aortic aneurysm, which erodes into the wall of the inferior vena cava, resulting in the formation of a fistula. ACF presents with various inconsistent symptoms and signs. ACF can be a diagnostic dilemma if not suspected and it is lethal if left untreated.

Colonic bleeding from migrated cement.

Migration of foreign bodies through the colonic wall can be the result of inflammation or effect of radiotherapy. Patients with such condition may remain asymptomatic. Careful assessment of patient' history can provide valuable information in symptomatic cases such as colonic obstruction or bleeding.

Apolipoprotein J as a predictive biomarker for restenosis after carotid endarterectomy: a retrospective study.

Carotid endarterectomy (CEA) is an effective surgical option for stroke prophylaxis in most patients. Restenosis after CEA can lead to re-intervention and adverse events, but the factors predicting restenosis are poorly understood. Apolipoprotein J (ApoJ) is considered to be a novel predictive factor of vascular restenosis and is associated with a large number of processes related to atherosclerosis and cell-cycle phases.

Paraoxonase-1: Characteristics and Role in Atherosclerosis and Carotid Artery Disease.

Paraoxonase-1 (PON-1) is a calcium-dependent enzyme that is synthesized in the liver and then secreted in blood where it is bound to high density lipoprotein (HDL). PON-1 is a hydrolase with a wide range of substrates, including lipid peroxides. It is considered responsible for many of the antiatherogenic properties of HDL.

Dermatofibrosarcoma protuberans coexisting in a patient with a vascular malformation-a rare coincidence.

Dermatofibrosarcoma protuberans with fibrosarcomatous differentiation (DFSP-FS) is a rare soft tissue tumor with more aggressive behavior and it is not clear what causes this type of skin cancer. We describe the case of a 48-year-old woman who was born with a vascular malformation in the sternal region and presented suddenly with a soft tissue sarcoma (DFSP-FS) in the same territory. She was initially treated by embolization as the sarcoma was misdiagnosed but the tumor within 6 months seemed to be growing rapidly and reached a giant dimension with ulceration and required surgical intervention.

Stenting of Subclavian Artery True and False Aneurysms: A Systematic Review.

Background: Aneurysms of the subclavian artery are usually the result of trauma, atherosclerosis, or thoracic outlet syndrome. Until the 90s, open surgical repair was considered the only therapeutic choice, exhibiting high complication rates. Since the first report of endovascular repair of subclavian aneurysms in 1991, promising results have been published.

Injury of the aortic isthmus is the second most frequent cause of death in cases of blunt traumatic injury. Conventional open repair is related to significant morbidity and mortality. Thoracic endovascular aortic repair (TEVAR) has increasing role in traumatic isthmic rupture, as it avoids the thoracotomy-related morbidity, aortic cross clamping, and cardiopulmonary bypass.
