INTRODUCTION: Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction...

Non-obstructive angioscopy (NOA) is used to visualize the surface of the coronary artery, and a clear visual field is obtained by injecting transparent fluid into the gap between the probing catheter and the fiber. This study examines visual field expansion by a dual infusion method, which involves an infusion from the probing and guiding catheters, and the relationships between visual grade and vessel characteristics. Thirty-two patients and thirty patients performed coronary plaque analysis with NOA using the conventional method and the novel dual infusion method, respectively...

Large pseudoaneurysms which compress the parent vessel are challenging lesions to successfully treat with endovascular therapy. We describe the endovascular treatment of a giant extracranial carotid artery (ECCA) pseudoaneurysm resulting in substantial mass effect on the common carotid artery (CCA) bifurcation using a telescoping dual covered stent graft construct. A 56-year-old male was diagnosed with an 8.5 cm × 13 cm pseudoaneurysm arising from the left CCA bifurcation, which was causing luminal narrowing of the CCA and proximal internal carotid artery (ICA)...

Giant basilar apex aneurysms are extremely challenging to successfully manage. The Pipeline Flex embolization device (PFED) is a new generation flow-diverting stent with a modified delivery system which allows resheathing of the stent after partial deployment. We describe a case of double-barrel Y-configuration stenting of a giant, recurrent basilar apex aneurysm using the PFED. A 73-year-old male was previously treated for an unruptured 11-mm basilar apex aneurysm with stent-assisted coiling using a Neuroform stent...

A 73-year-old woman with arteriosclerosis obliterans (ASO) was underwent a crossover stenting for an aortoiliac bifurcation from the right common iliac artery (CIA) with a self-expandable bare-metal stent (SE-BMS); however, a new stenosis later occurred just behind the bifurcation of the left CIA. An ex vivo experiment demonstrated that culotte-stenting by additional implantation of a balloon-expandable bare-metal stent (BE-BMS) through stent struts of the SE-BMS would be empirically infeasible. Although we had initially planned a T-stenting for the additional implantation of a BE-BMS in the left CIA, we finally deployed the stent in the CIA with the proximal end protruding into the previously-implanted SE-BMS through the stent struts to avoid incomplete coverage of the stenosis by reference to the ex vivo experiments...

A significant controversy exists regarding the clinical impact of hemodynamic depression on major adverse events after carotid artery stenting (CAS). The purpose of this study was to evaluate the incidence, predictors, and clinical significance of hypotension after CAS. A total of 118 cases of carotid artery stenosis were treated with CAS. Hypotension was defined as sustained systolic blood pressure <80 mmHg and requiring intravenous administration of vasopressor to maintain adequate systolic blood pressure after the procedure...

BACKGROUND: In-stent neoatherosclerosis (ISNA) is a final common pathway of late-stent failure. However, distribution of ISNA has been little reported. This study was to evaluate the localization of ISNA in relation to curvatures and bifurcations after stent implantation using optical coherence tomography (OCT). METHODS: We retrospectively selected patients who underwent OCT examination ≥12 months after stent (sirolimus-eluting stents, SES) implantation. A stent curvature was defined if the angulation of the stent segment was >29°...

BACKGROUND: Aorto-ostial lesions as well as bifurcation lesions still provide challenges in percutaneous coronary intervention (PCI), as meticulous stent placement is needed. The Szabo-technique, which uses a second wire to anchor the stent at the osmium, may be helpful here. In this article, we will provide detailed information on the technique including video material as well as procedural and long-term follow-up data of a cohort of patients treated with this technique. METHODS AND RESULTS: A retrospective single-centre study was performed in patients undergoing Szabo-PCI from 2014 to 2016 (n=28)...

Coronary artery perforation during percutaneous coronary intervention is a rare, but potentially lethal complication. Immediate balloon expansion at the perforation site can halt the bleeding. Implantation of a coronary polytetrafluoroethylene (PTFE)-covered stent enables the efficient endovascular repair of a coronary artery perforation. However, if the perforation occurs at a bifurcation, a PTFE-covered stent may jail the side branch. We report a difficult case of blowout coronary perforation (Ellis type III) at a left main coronary artery bifurcation, which was successfully sealed with a PTFE-covered stent without interference with the side branch coronary artery circulation...

BACKGROUND: Based on randomized trials, carotid endarterectomy (CEA) is the standard procedure for patients with a 50-99% symptomatic carotid stenosis and carefully selected patients with an asymptomatic high-grade carotid stenosis. Carotid artery stenting (CAS) is a technical alternative for patients with a high surgical risk or difficult anatomic conditions (e.g., recurrent stenosis). This study aims to provide an overview of anatomic factors associated with a higher risk of CEA complications...

Side branch occlusion, which was one of the common complications in percutaneous coronary interventions, was closely associated with cardiac death and myocardial infarction. Clinical guidelines also support the importance of preservation of physiologic blood flow in SB during PCI to bifurcation lesions. In order to avoid side branch occlusion during stent implantation, we often performed the jailed wire technique, in which a conventional guide wire was inserted to the side branch before stent implantation to the main vessel...
