We describe a case of an infected popliteal artery stent with septic emboli presenting 6 years after peripheral vascular intervention for intermittent claudication. Management included resection of the stent and popliteal artery and revascularization by femoral-popliteal bypass with autogenous vein. This case demonstrates that peripheral stent infections can develop years after intervention. We performed an English language PUBMED literature review of arterial peripheral vascular stent infections on using the search term, "Non-coronary stent or stent graft infection from 1966 to present...

Gene therapy for avoiding intimal hyperplasia of vein grafts after coronary artery bypass grafting is still discussed controversially. A promising application of gene therapy in vein grafts is the use of antisense oligonucleotides to block the expression of genes encoding cell cycle regulatory proteins in vascular smooth muscle cells. C-myc, either directly or by regulating the expression of other proteins, controls cell proliferation, apoptosis and cell survival, tissue remodeling, angiogenesis, cell metabolism, production of inflammatory and anti-inflammatory cytokines, and also participates in cell transformation...

Myocardial infarction (MI) induced by acute coronary arterial occlusion is usually secondary to atherosclerotic plaque rupture. Dysregulated response of vascular smooth muscle cells (VSMCs) in atherosclerotic plaques may promote plaque rupture. Cadherins (CDHs) form adherens junctions and are known stabilizers of atherosclerotic plaques. To date, the expression patterns of cadherin have not been well investigated in MI aortic VSMCs. We aimed to investigate the expression of cadherin genes in the aortic wall of patients with and without MI...

Three cases of internal carotid artery (ICA) injury during endoscopic endonasal surgery were analyzed, including 1 case of recurrent malignancy of sphenoid sinus, 1 case of intraorbital meningioma and 1 case of optic neuropathy. Salvage sphenoid sinus packing with gauze strip was managed in all the three cases. One patient operated a permanent closure of the carotid system intraoperatively and died after surgery. Among 2 survival cases, one patient accepted the endovascular embolization subsequently; the other patient was cured by intravaseular stent graft implantation without craniocerebral or ocular complicatitms...

To compare the properties between decellularized rabbit carotid artery with different cross-linked technologies.
 Methods: The decellularized rabbit carotid arteries were randomly divided into a photo-oxidation group and a procyanidins group. One group was cross-linked with photo-oxidation and the other group was cross-linked with procyanidins. The in vitro or in vivo properties of the two groups were evaluated by testing heat-shrinking temperature, max tensile strength and the max elongation or by testing tissue structure, inflammatory reaction and calcification degree...

BACKGROUND: Type 2 diabetes mellitus (T2DM) is an independent risk factor of cardiovascular disease (CVD), however, the underlying mechanisms are largely unknown. Using non-atherosclerotic internal thoracic arteries (ITAs) obtained from coronary artery bypass grafting, we previously identified a distinct elevation in the level of proteins comprising the arterial basement membrane in T2DM patients not treated with metformin. Altered transcription of genes encoding these proteins has not been observed, indicating alternative mechanisms of dysregulation...

Venous malformations are the most common slow-flow vascular malformations; they are not prone to volume decrease over time and invasive treatment is usually required. There are two main techniques to address the definitive therapy of these lesions: sclerotherapy and surgical excision, each with its own advantages and disadvantages. We report the case of a 56 year-old man who came to our attention with persistent pain after multiple unsuccessful attempts to treat a large venous malformation located in the area of the right knee...

The persistent sciatic artery (PSA) is a remnant of the fetal circulatory system that is preserved in less than 0.1% of the population. Up to 60% of patients with this vascular anomaly will go on to development of a PSA aneurysm (PSAA), which can produce a variety of symptoms including neuropathy, claudication, and acute limb-threatening ischemia. Historical management is by open operation and interposition grafting, which can be highly morbid. We describe successful management of a large, symptomatic PSAA by endovascular stent-grafting with intermediate term follow-up...

Preservation of the residual hypogastric artery (HGA) in patients with previous endovascular aortic aneurysm repair (EVAR) may require complex operative strategies. We report an alternative technique to preserve the residual HGA with the Gore Excluder Iliac Branch endoprosthesis (IBE) in urgent situations. MethodsWe report the case of two high-risk patients (unfit for open surgery), with previous EVAR and exclusion of one HGA, treated in emergency setting. Both patients met the anatomical requirements for Gore IBE use...

BACKGROUND: Intensive care patients experience poor sleep quality. Psychological distress and diminished health-related quality of life (HRQOL) are also common among former intensive care unit (ICU) patients. Coronary artery bypass graft (CABG) surgery is a frequent reason adults require treatment in ICU. The effect of on- versus off-pump surgery on sleep and recovery has not been reported. OBJECTIVE: The aim of this study was to assess sleep quality of CABG patients during and after ICU, psychological well-being, HRQOL during recovery, and whether on- versus off-pump surgery affects sleep and recovery...

OBJECTIVE: To evaluate whether hospital participation in accountable care organizations (ACOs) is associated with reduced Medicare spending for inpatient surgery. BACKGROUND: ACOs have proliferated rapidly and now cover more than 32 million Americans. Medicare Shared Savings Program (MSSP) ACOs have shown modest success in reducing medical spending. Whether they have reduced surgical spending remains unknown. METHODS: We used 100% Medicare claims from 2010 to 2014 for patients aged 65 to 99 years undergoing 6 common elective surgical procedures [abdominal aortic aneurysm (AAA) repair, colectomy, coronary artery bypass grafting (CABG), hip or knee replacement, or lung resection]...

Intestinal transplant (IT) is one of the least common forms of organ transplant but is increasing both in volume of cases and number of centers performing intestinal transplants, with the busiest centers in North America and Europe. IT can be performed in isolation or as part of a multivisceral transplant (MVT). Intestinal failure either in the form of short gut syndrome or functional bowel problems is the primary indication for IT. The normal post-surgical anatomy can be variable due to both recipient anatomy in regard to amount of residual bowel and status of native vasculature as well as whether the transplant is isolated or part of an multivisceral transplant...

PURPOSE: This study was designed to investigate the distribution of vasa vasorum in walls of failed aorto-coronary venous grafts. METHODS: Fifty-one diseased venous grafts harvested from 39 patients underwent qualitative histological evaluation. The morphology of the grade of the pathological changes and the extent of the vascularisation were examined, and related to the length of the interval between the primary surgery and the explantation. The obtained results were placed into five groups, substantially differing one from the other in morphology and vascularisation...

Penetrating aortic ulcer (PAU) is an acute aortic syndrome that can proceed to life-threatening aortic dissection or even aortic rupture. Isolated iliac aneurysms are relatively rare and often asymptomatic due to their deep pelvic location but are frequently associated with high mortality with rupture. We report a case of a 68-year-old man with a symptomatic penetrating ulcer in the descending aorta and an asymptomatic right iliac aneurysm involving the common and internal iliac arteries. The patient was successfully treated by endovascular repair in a single-stage manner using stent grafts in the descending aorta and right common iliac artery after coil embolization of the right internal iliac artery...
