INTRODUCTION: Single stent deployment leads to a change in vascular geometry in wide necked bifurcation aneurysms. In some complex cases, the use of the single stent technique might not be sufficient or may not be feasible. The kissing-Y stenting technique appears to be an alternative endovascular treatment option. The aim of this study was to evaluate the effects of the kissing-Y stenting technique on vascular angular remodeling. METHODS: 21 patients with wide necked intracranial bifurcation aneurysms at different sites (10 anterior communicating artery, 6 middle cerebral artery, 3 basilar artery, 1 vertebral artery/posterior inferior cerebellar artery, 1 internal carotid artery/posterior communicating artery) were treated with 44 closed cell stents (follow-up 2012-2016) using the kissing-Y stenting technique...

AIMS: We conducted this study to evaluate the efficacy of drug-coated balloon therapy for in-stent restenosis after coronary bifurcation stenting. METHODS AND RESULTS: Patients who underwent angioplasty with at least one paclitaxel-coated balloon for in-stent restenosis after bifurcation intervention using a two-stent approach were included. Two types of paclitaxel-coated balloon were used, with either iopromid (iopromide-PCB) or butyryltri-n-hexyl citrate excipient (BTHC-PCB)...

PURPOSE: to describe the use of the combination of a conical custom-made TREO® (TREO CM) stent-graft in the treatment of a saccular abdominal aortic endograft (AAA) with long but tight and calcified distal neck. TECHNIQUE: A 65-year female patient was treated for a saccular 5.2 cm AAA with a 3cm-long but calcified and tight (16mm) distal neck, precluding the safe use of a bifurcated endograft. Since the patient refused an open surgery, a conical TREO CM endograft was manufactured with 20% proximal oversizing, whereas the 3cm caudal sealing segment demonstrated a conical configuration comprised of a 2cm and 1cm nitinol-supported zones of 20% and 10% oversizing, respectively, in order to avoid excessive strain and incomplete expand at the most distal calcified area, leading ultimately to an insidious infolding and consequent type Ib endoleak...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...

BACKGROUND: Endoleaks of type Ib and III are relatively common causes of re-intervention after EVAR. The aim was to determine underlying causes and identify anatomical factors associated with these re-interventions. METHODS: A total of 444 patients with standard bifurcated stent grafts were included in a retrospective observational study. Patients requiring additional iliac stent grafts (n = 24) were compared to those who did not (n = 420). Pre- and post-operative CT examinations were reviewed in patients with additional iliac stents...

We report on two cases in which Y-shaped coronary bifurcations were treated with the use of Bioresorbable scaffolds. The first case was of a 50-year-old man with NSTEMI. Coronary angiography showed stenosis involving a Y-shaped bifurcation of proximal to mid LAD and diagonal. The lesion was wired using two 0.14 BMW guide wires, followed by serial pre-dilatation of LAD and Diagonal branch. The stent into proximal LAD was deployed first as a skirt (3.5 × 12 BVS). Stent was post-dilated. A second 2.5 × 28 BVS was deployed into diagonal branch, protruding backwards; along with a 2...

AIMS: Mechanisms of lumen compromise after provisional side-branch (SB) stenting are poorly understood. In this study we investigated the impact of bifurcation angle, plaque composition, and procedural strategy on SB compromise. METHODS AND RESULTS: Computer simulations of stent implantation were performed in Medina (1,1,1) bifurcation models. Provisional SB stenting was replicated including post-dilation after main branch stenting. Two bifurcation angles (45°,70°) and four plaque types (fully lipid, fully fibrous, lipid with half and full calcified ring distal to the carina) were tested...

Renal artery aneurysms (RAAs) are rare with an estimated incidence of 0.1% in the general population, and they represent approximately 25% of all visceral aneurysms. The gold standard of treatment is open surgery, but it is associated with a high risk of nephrectomy, mortality, and morbidity. Less invasive endovascular therapies are becoming increasingly common for the treatment of RAAs. Here, we aimed to report three cases of wide-necked complex renal artery aneurysms treated endovascularly using stent-assisted coil embolization with self-expandable stent nitinol Solitaire AB and Concerto Axium coils...
