Vascular stent graft infection

OBJECTIVE/BACKGROUND: The use of cryopreserved saphenous veins (CSVs) for the treatment of lower extremity peripheral arterial disease is an attractive option when there is no available autogenous vein. Prior studies found CSVs are at risk for aneurysmal degeneration requiring reoperation. As the management of these complications and patient outcomes is not well described, the objective of this case series is to describe the open and endovascular management of degenerative CSVs at a tertiary community center...

PURPOSE: : Endotension is a rare late complication characterized by an increase in sac size without any type of endoleak following endovascular aortic aneurysm repair (EVAR). Due to its rarity, few studies have demonstrated the mechanism behind and the management of endotension. In this study, we aimed to better understand the treatment and the long-term outcome of endotension in a single-center cohort. MATERIALS AND METHODS: : This study was designed for a retrospective review of the patients diagnosed with endotension between January 2006 and December 2017...

KEY CLINICAL MESSAGE: The presence of multiple pseudoaneurysms in a patient should prompt investigations for the underlying etiologies including autoimmune and immunosuppressive disease processes. Treatment options include open repair and endovascular stenting. ABSTRACT: Pseudoaneurysms (also known as false aneurysms) are atypical dilatations or outpouchings from a vessel which are not always contained by the three layers of a normal vessel wall, namely the intima, media, and adventitia...

A fluoropolymer-based drug-eluting stent was implanted in an arteriovenous graft outflow venous stenosis. Two and a half years later, due to a local infection, the stent was removed surgically, and a pathological evaluation was conducted. The stent struts exhibited partial endothelial cell coverage, with the remaining surface predominantly covered by fibrin. Notably, there was no evidence of restenosis or aneurysmal change.

BACKGROUND: Vascular graft infection is a very complex disease. Although complete excision of the infected grafts with extra-anatomic bypass or in situ reconstruction is a general treatment strategy, some concerns including reinfection in the new graft remain. CASE REPORT: An 88 year-old man presented to the hospital with abdominal swelling and bleeding. The patient had undergone revascularization for aorto-iliac occlusive disease twice in the past. The first procedure had been performed 15 years previously, with right ilio-femoral bypass grafting for right iliac artery occlusion and stent implantation for left iliac artery stenosis...

OBJECTIVES: The study compared the outcomes between covered-stents grafting (CSG) and ligation of femoral artery (LFA) in the treatment of infected femoral pseudoaneurysm (IFP) caused by intravenous drug injection. METHODS: From 1st January 2016 to 30th November 2021, the clinical data of patients with IFP caused by intravenous drug injection who underwent CSG ( n = 31, 55.4%) and LFA ( n = 25, 45.4%) are retrospectively analyzed. We compared the baseline characteristics and clinical outcomes of the two groups, including early and late mortality and morbidity...

Mycotic pseudoaneurysms can be a serious and life threatening complication of left sided infective endocarditis. They most commonly affect the major axial vessels. Profunda femoris artery (PFA) aneurysms are rare and present in only 0.5% of all peripheral aneurysms, regardless of the underlying etiology. We present a case of a patient who underwent mitral valve repair for severe mitral regurgitation secondary to culture negative IE which was complicated by multiple mycotic pseudoaneurysm. The PFA pseudoaneurysm which was affected and was complicated with a large hematoma compressing the femoral nerve...

Multi-visceral transplantation (MVT) is a complex surgical procedure involving the transplantation of multiple abdominal organs as a single unit, typically used as bailout treatment of patients with devastating abdominal pathologies. Due to the complexity of the procedure, major and even life-threatening complications can happen. Vascular complications, including anastomotic breakdowns or pseudoaneurysms due to infections, can be universally lethal. Open surgical repair is often not an option due to the hostile operative field...

A male patient, 70 years of age, was evaluated for an infected thoracic endovascular aneurysm repair (TEVAR). After presenting with persistent fever, a positron emission tomography scan found an infected aortic stent graft. The patient underwent open repair with explantation of the infected TEVAR, extensive periaortic debridement, graft replacement with a Dacron graft, and complete coverage with a latissimus dorsi muscle flap. Tissue culture revealed Clostridium spp. He was discharged home with long-term ampicillin and sulbactam...

BACKGROUND Managing IgG4-related disease (IgG4-RD) in the context of vascular complications, such as aneurysms, poses significant challenges, particularly when considering surgical intervention options. The risk of rupture and infection in patients on long-term glucocorticoid therapy complicates treatment decisions. CASE REPORT A 63-year-old woman with a history of IgG4-RD presented with a ruptured right iliac artery aneurysm. She was on long-term oral glucocorticoid therapy. Initial emergency endovascular stent graft implantation was followed by embolization for suspected arterial bleeding and subsequent Salmonella bacteremia...

Hybrid thoracic endovascular aortic repair (TEVAR) has been proved to be an effective and reliable treatment option for aortic arch diseases requiring extension of the proximal landing zone. However, hybrid TEVAR was associated with potential risk of post-operative complications, including cerebral infarction, endoleaks and paraplegia. Here we reported a rare case of bypass graft infection complicated with mitral valve aneurysm and perforation following landing zone 2 hybrid TEVAR procedure, who presented with symptoms of fever, major bleeding and anastomotic pseudoaneurysm and received emergency bypass graft removal and stent implantation with acceptable short and midterm follow-up results...

BACKGROUND: Superior vena cava syndrome in hemodialysis patients resulting from previous or current use of a tunneled central vein catheter is a rare but potentially severe condition. Two aspects have to be addressed during management and treatment: the restoration of central venous flow and the creation of an alternative vascular access to guarantee hemodialysis. RESEARCH DESIGN: Conforming to the current guidelines and literature, we present a stepwise approach and discuss therapeutic options...

PURPOSE: To observe the short-term efficacy of thoracic endovascular aortic repair (TEVAR) using a single left common carotid artery chimney stent combined with a Castor single-branched stent-graft (SC-TEVAR) in the treatment of zone 2 (Z2) aortic diseases. MATERIALS AND METHODS: To conduct a retrospective analysis of 20 patients with Z2 aortic diseases who were treated in our department from June 2021 to April 2022. The lesions included true aortic degenerative aneurysms with diameter ≥5...

Coronary stent infection (CSI) is a rare but potentially life-threatening disease, the incidence of which has been on a rise over the past 2 decades. Surgery seems the treatment of choice, providing a definitive diagnosis of CSI and removing the source of infection, repairing aneurysms, and providing bypass vascular grafts if feasible. Thorough evaluation and a multidisciplinary approach lead to detection and a better outcome. We report a patient who presented with symptoms of heart failure and shock, who received a diagnosis of CSI complicated by empyema with pleuropericardial fistula...

BACKGROUND: Stent grafts (SGs) are widely used in hemodialysis access procedures to maintain function and patency of the access circuit. There are no reports to date describing complete relining of the access circuit with SGs for extreme access salvage. OBJECTIVE: To report outcomes and experience with complete SG relining of the hemodialysis access circuit. METHODS: From April 2020 to May 2023, all hemodialysis salvage procedures that included complete relining of the access circuit with SGs were retrospectively analyzed from a prospectively collected database of 970 hemodialysis access interventions...

BACKGROUND: Hemodialysis access sites can be complicated by both true and false aneurysms with significant potential morbidity. Aneurysms have traditionally been treated by a variety of surgical methods. Less commonly, endovascular treatment with stent graft placement has been used as an alternative to open surgery. METHODS: Four patients with symptomatic aneurysmal disease in the hemodialysis access site were treated. All patients had stent grafts (SGs) placed across the diseased segment...

Arterioureteral fistula is a rare but life-threatening condition. An endovascular treatment approach is commonly used; however, there is a potential risk of infection. We present a case in which a patient presented with abdominal pain and was diagnosed with a ruptured internal iliac artery aneurysm and a subsequent arterioureteral fistula. An aortic stent graft was inserted to treat the arterioureteral fistula, but it subsequently became infected, resulting in the patient's death. This case underscores the importance of early diagnosis and treatment of arterioureteral fistula and the possibility of graft infection...

Over the last few decades, the use of covered stent grafts became increasingly popular; as it plays a pivotal role in the management of various atherosclerotic diseases that are rising in both incidence and prevalence. Subsequently, vascular stent infections, although rare, are becoming a well-recognized complication with possibly devastating consequences, owing to the difficulties associated with its diagnosis and treatment. This has prompted significant interest in the condition regarding its pathophysiology, modifiable and non-modifiable risk factors, diagnostic and therapeutic approaches, and the possible implementation of prophylactic measures...

In this case report, we describe the clinical course of a complicated transplant renal artery (TRA) pseudoaneurysm, clinically featured by gross and massive hematuria one month after a kidney transplant was performed on a 50 year-old male patient. TRA pseudoaneurysm is a rare but potentially life-threatening complication that may result in bleeding, infection, graft dysfunction/loss, lower limb ischemia/loss, hemorrhagic shock, and death. TRA pseudoaneurysm treatment remains challenging as it needs to be tailored to the patient characteristics including hemodynamic stability, graft function, anatomy, presentation, and pseudoaneurysm features...

Vascular access is essential for hemodialysis (HD) in patients with end-stage renal disease (ESRD). When the standard of care arteriovenous fistula (AVF) is limited, secondary to aneurysmal degeneration, trauma, and thrombus, interposition grafting is a reasonable reconstruction approach. As these grafts and comorbidities place ESRD patients at sustained risk of complications, reconstructions with regenerative medicine biologic conduits hold promise in improving safety and efficacy. Here, a biocompatible human acellular vessel (HAV) is our conduit of interest...
