BACKGROUND: Open surgical repair remains the "gold standard" treatment for chronic type B aortic dissection (cTBD) with aneurysm. Thoracic endovascular aortic repair (TEVAR) has gained popularity in recent years for the treatment of thoracic aortic diseases, including cTBD. We assessed the effectiveness of TEVAR in the treatment of cTBD using the Vascular Quality Initiative (VQI) database. METHODS: The VQI registry identified 4713 patients treated with TEVAR from July 2010 to November 2015, including 125 repairs for cTBD...

A 72-year-old man previously treated for an abdominal aortic aneurysm (AAA) was diagnosed with the 70-mm-sized type IIIb aortic dissection. Endovascular repair was considered, but there was no stent graft passing through the 8-mm iliac graft that was used for open repair of the AAA. We sealed the 5-mm-sized intimal tear site, using an Amplatzer Vascular Plug, which successfully repaired. The patient was discharged and had no complications. Serial follow-up computerized tomography scans showed that the vascular plug was positioned without migration, and the size of the aorta decreased...

BACKGROUND: Correlations between the ACC/AHA coronary lesion classification and clinical outcomes in the contemporary percutaneous coronary intervention (PCI) era are not well established. METHODS: We analyzed clinical characteristics and outcomes according to ACC/AHA lesion classification (A, B1, B2, C) in 13,701 consecutive patients from the Melbourne Interventional Group (MIG) registry. Patients presenting with STEMI, cardiogenic shock and out-of-hospital cardiac arrest were excluded...

OBJECTIVES: Ninety-five per cent of those operated on for popliteal artery aneurysm (PA) are men. Thus, PAs in women are difficult to investigate. The aim was to study the disease in women. METHODS: Women treated for PA in 1987-2012, prospectively registered in the Swedish vascular registry, Swedvasc, supplemented by case records, were compared with the larger male cohort. Survival was determined through cross linkage with the National Population Registry. RESULTS: 1509 patients (men and women), 1872 legs, were identified; of these 74 patients (4...

Celiac trunk aneurysms are uncommon vascular lesions; treatment is usually an open surgical operation; in the medical literature, only few cases of celiac aneurysm treated with endovascular technique are reported; coil positioning or stent-graft placement are described using a femoral vascular access as first choice.Here we describe the case of a 57-year-old man with an asymptomatic large celiac trunk aneurysm involving the origin of the splenic, left gastric and hepatic arteries. The patient was treated in an elective clinical setting with a totally endovascular procedure performed through the left radial artery...

Iliac artery occlusive disease can present as a sudden-onset acute thrombotic or thromboembolic event or as a chronic progressive atherosclerotic process that presents as claudication progressing to rest pain. Depending on the clinical presentation, the diagnosis is usually confirmed through Doppler vascular ultrasound, CT angiography, or MR angiography; the choice of imaging is usually based on modality availability and the presence of patient comorbidities such as chronic kidney disease. The Trans-Atlantic Inter-Society Consensus II classification system is commonly used to describe the extent of the peripheral vascular disease...

BACKGROUND: The endovascular management of arterial injuries has resulted in reduced operating time, blood loss, hospital mortality, lower incidence of sepsis, and decrease in mortality rates. For penetrating trauma, however, the benefits of endovascular therapy are questionable. PATIENTS AND METHODS: Data were obtained by retrospective analysis of electronic medical records. All patients with vascular trauma seeking care at our institution from January 2010 to December 2015 were reviewed...

OBJECTIVES: Vascular injury is a rare complication of spinal instrumentation. Presentation can vary from immediate hemorrhage to pseudoaneurysm formation. In the literature, surgical approach to repair has varied based on anatomy, acuity of diagnosis, infection, and available technology. In this manuscript, we aim to describe our institutional experience with vascular injuries in thoraco-lumbar spine surgery. PATIENTS AND METHODS: We report our institutional experience of three cases of vascular injury secondary to pedicle screw misplacement and their management, as well as a review of the literature...

BACKGROUND: Endovascular repair for mycotic aortic aneurysm (MAA) is a less invasive alternative to open surgery, although the placement of a stent graft in an infected environment remains controversial. In this study, we developed hybrid biodegradable, vancomycin-eluting, nanofiber-loaded endovascular prostheses and evaluated antibiotic release from the endovascular prostheses both in vitro and in vivo. METHODS: Poly(D,L)-lactide-co-glycolide and vancomycin were dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol...

Takashi Yamauchi, Suguru Kubota, Kosei Hasegawa
Open surgery for a type Ib endoleak after thoracic endovascular aortic repair is associated with some knacks and pitfalls, particularly in cases wherein the distal edge of a stent graft is located at just supraceliac aorta and the renovisceral segment and infrarenal aorta do not require surgical intervention. Here we describe the invaginated graft insertion technique to provide an easy and secure anastomosis in such clinical situations. This procedure may be feasible for anastomosis between a prosthetic vascular graft and a previously deployed stent graft when the location of the anastomosis is distant from the surface of the skin incision with a narrow and limited surgical view...

The treatment of patients with severe coronary and peripheral artery disease represents a significant clinical need, especially for those patients that require a bypass graft and do not have viable veins for autologous grafting. Tissue engineering is being investigated to generate an alternative graft. While tissue engineering requires surgical intervention, the release of pharmacological agents is also an important part of many tissue engineering strategies. Delivery of these agents offers the potential to overcome the major concerns for graft patency and viability...

Background -Extracellular matrix (ECM) remodeling contributes to in-stent restenosis and thrombosis. Despite its important clinical implications little is known about ECM changes post-stent implantation. Methods -Bare-metal (BMS) and drug-eluting stents (DES) were implanted in pig coronary arteries with an overstretch under optical coherence tomography guidance. Stented segments were harvested 1, 3, 7, 14 and 28 days post-stenting for proteomics analysis of the media and neointima. Results -A total of 151 ECM and ECM-associated proteins were identified by mass spectrometry...

We developed a biodegradable polycarbonate that demonstrates antithrombogenicity and vascular cell adhesion via organocatalytic ring-opening polymerization of a trimethylene carbonate (TMC) analogue bearing a methoxy group. The monoether-tagged polycarbonate demonstrates a platelet adhesion property that is 93 and 89% lower than those of poly(ethylene terephthalate) and polyTMC, respectively. In contrast, vascular cell adhesion properties of the polycarbonate are comparable to those controls, indicating a potential for selective cell adhesion properties...

A 78-year-old man presented at Eulji University Hospital due to an abdominal aortic aneurysm with maximum diameter of 52 mm, which had been increased from 45 mm over 6 months. He underwent embolization of the left internal iliac artery with vascular plug, prior to endovascular abdominal aortic repair with a bifurcated stent graft system. Unfortunately, the inserted vascular plug was maldeployed and protruded into left external iliac artery, and caused acute limb ischemia. Because revascularization of the occluded segment was failed, emergent hybrid approach with aorto-uni-iliac stent grafting and femoro-femoral bypass was done, successfully...

Infection of a vascular prosthesis or endovascular stent-graft is probably the most serious complication that may occur after implantation and dramatically affects the patient's outcome. The most common etiology of graft and/or prosthetic valve infection is usually wound-related infection, followed by seeding from distant infection sites (lung, urinary tract). Surgical treatment is almost always required but even after surgery, morbidity can be significant. Operative procedure must be tailored according to the individual patient and to the experience of the surgical team...

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according to the size of laceration and its proximity to the renal hilum. Arteriovenous fistula and pseudoaneurysm are the most common iatrogenic biopsy-related or surgery-related vascular injuries in native kidneys. The approach to renal artery injuries has changed over time from more aggressive intervention to more conservative observational or endovascular management, including selective transcatheter arterial embolization (TAE) and the placement of stents/stent grafts...
