Bioresorbable vascular scaffold overlap evaluation with optical coherence tomography after implantation with or without enhanced stent visualization system (WOLFIE study): a two-centre prospective comparison
Abstract To assess if enhanced stent visualization (ESV)-guided implantation of overlapping bioresorbable vascular scaffold (BVS) is superior to angiography alone-guided implantation in the reduction of overlap length. WOLFIE is a two-centre prospective open study enrolling 30 patients treated with implantation of at least two overlapping BVS. In the first centre (London), BVS implantation was guided by conventional angiography, while in the second centre (Ferrara), an ESV system was systematically employed. The primary endpoint of the study was overlap length. Secondary endpoints were: stacked struts number, area, thickness, and amount of clusters. In the ESV-guided group, overlap length was significantly lower compared to angiography-guided group [0.9 (0.6–1.8) vs. 2.2 (1.3–3.2) mm, p = 0.02]. Similarly, all secondary endpoints were significantly reduced. ESV-guided implantation of overlapping BVS is safe and effective in minimizing both overlap length and number of stacked struts.
CONCLUSION: Macular edema is the principal cause of visual acuity decline in retinal vein occlusions; its prognosis is similar to that of retinal venous occlusions in general, hampered by the possibility of ischemic conversion. The diagnosis of retinal vein occlusion is clinical and does not require angiography. This remains, however, a useful exam to better analyze the retinal periphery as well as for the detection of various modalities during spontaneous progression.

ConclusionsThe FAVOR III China study will be the first randomized trial to examine the effectiveness and cost-effectiveness of a QFR-guided versus an angiography-guided PCI strategy in CAD patients.
Authors: Wang H, Liu Z, Shen Z, Fang L, Zhang S Abstract OBJECTIVES: To identify the predictors of coronary involvement, and to determine the impact of coronary involvement on long-term outcomes in patients with Takayasu's arteritis (TAK). METHODS: This retrospective cohort study of TAK patients with coronary evaluation by angiography or computed tomography angiography was conducted in a tertiary center between 1990 and 2018. Risk factors for coronary involvement and predictors of overall survival, cardiovascular event-free survival, and relapse-free survival were investigated. RESULTS: The median follow-up...
Recurrent cerebral infarctions associated with post-internal carotid artery dissection are a disabling complication of aortic dissection, which sometimes occur even without the progression of the aortic or internal carotid dissection . Accurate assessment of the dynamics of cervical blood flow is essential for the detection of blood stagnation and the prevention of delayed recurrent infarctions with appropriate anticoagulant therapy. Complicated flow due to interconnections of dissected lumens is a substantial constraint to accurate blood flow assessment; however, catheter angiography of the dissected artery is contraindicated.
To compare clinical characteristics and treatment outcomes of intraarterial thrombectomy (IAT) in acute basilar artery occlusion (BAO) with and without underlying intracranial atherosclerotic stenosis (ICAS) and to investigate the usefulness of preprocedural CT angiography findings in the diagnosis of ICAS.

AbstractBackgroundPituitary adenylate cyclase-activating polypeptide-38 (PACAP38) induces headache in healthy volunteers but the precise mechanisms by which PACAP38 leads to headache are unclear. We investigated the headache preventive effect of sumatriptan and ketorolac on PACAP38-induced headache in healthy volunteers. In addition, we explored contribution of vascular mechanisms to PACAP38-induced headache using high resolution magnetic resonance angiography.MethodsThirty-four healthy volunteers were divided in two groups (A and B) and received infusion of PACAP38 (10 picomol/kg/min) over 20 min. Group A was pret...
ConclusionCovered stent placement is a safe and effective alternative for treating HAP patients with high risk of severe complications after hepatic artery embolization. Larger stent grafts (> 4 mm in diameter) may achieve better prognosis.
Background: There is conflicting data on the effect of carotid revascularization on cognitive function. Objective: To examine cerebral blood flow and cognitive function after carotid revascularization. Methods: Patients with unilateral, asymptomatic hemodynamically significant carotid artery stenosis (80% by computed tomography angiography or magnetic resonance angiography) were eligible. Cerebral blood flow was measured preoperatively and 1 month postoperatively using quantitative phase contrast magnetic resonance angiography.
CONCLUSION: Percutaneous rheolytic thrombectomy is safe and effective for thrombosed arteriovenous grafts, with acceptable primary and secondary patency rates. Higher clinical success was found in patients never treated before and when the procedure was carried out within 24 h from the clinical onset of thrombosis.
