Theoretical prediction of side branch compromise after main branch stenting in coronary bifurcation

Journal of Geriatric Cardiology 2008年第2期5卷 91-100页

One of the main problems of treatment of bifurcation lesions is side branch (SB) stenosis appearing after stent placement in the main vessel. The aim of this study was to create quantitative method for prediction of side branch compromise extent. We accepted that the main mechanism for SB ostial stenosis is flow divider (FD) displacement from stent struts after stent implantation in the main vessel. Using easily measurable parameters from coronary angiography, as SB diameter, angle á (initial angle between axes of parent vessel and SB axis) and angle á' (angle between above mentioned axes after stent placement) we can calculate percentage diameter stenosis at branch ostium (%DS): %DS = sin (á - á')/(tan á). In boundary condition of full FD displacement %DS = cos á. We tested our theoretical predictions with fluoroscopic observation of elastic wall model of bifurcation (45o distal angle between branches) permitting wall deformations with stent. There is full coincidence of values of %DS and percentage area stenosis (%AS). The regular formulas for calculations of %DS and %AS overestimate stenosis severity between 10% and 25%. Our model tests have shown full coincidence between predicted values for %DS and observed values. We demonstrate that part of the SB ostium is not visible in regular angiography and contributes to ostial lumen area. This is a method that permits quantitative prediction of side branch compromise.

Bifurcation coronary lesions are relatively frequent in today＇s interventional cardiology practice, averaging between 10%-15% of all interventions （PCIs）. Several percutaneous coronary problems inherent in the treatment of bifurcation lesions are periprocedural side branch （SB） compromise （composite of SB closure or appearance of significant ostial stenosis after main vessel （MV） stenting causing ischemia） frequently related to periprocedural myonecrosis,

Topical anaesthesia before transradial approach for supraoartic vessels angiography and stenting in the elderly： a feasible alternative

引用

Journal of Geriatric Cardiology 2017年第10期14卷 644-648页

Over the years, the use of transradial approach (TRA) for carotid artery stenting (CAS) with distal embolic protection has been recognized as a valid alternative to the conventional femoral approach, improving the outcomes compared to carotid endoatherectomy. Indeed, despite the femoral artery remains the conventional access site for the endovascular treatment of supraoartic vessels, concomitant anatomical variations and/or peripheral vascular disease could complicate the cannulation of such arteries.[4] Moreover, the TRA has been related with a lower incidence of bleeding complications and a shorter bed rest after the interventional procedure.

AIM:To study intestinal permeability(IP) and its relationship to the disease activity in patients with inflammatory bowel diseases(IBD)-Crohn's disease(CD) and ulcerative colitis(UC).METHODS:Fifty-eight patients with active IBD(32 with CD and 26 with UC) and 25 healthy controls consented to participate in the *** clinical activity of CD was estimated using the Crohn's Disease Activity Index(CDAI),and the endoscopic activity of UC using the Mayo scoring *** was assessed by the rise in levels of iohexol,which was administered orally(25 mL,350 mg/mL) 2 h after *** and six hours later serum(SIC mg/L) and urine(UIC g/mol) iohexol concentrations were determined by a validated HPLC-UV ***:In the CD group,SIC values at 3 h(2.95 ± 2.11 mg/L) and at 6 h after ingestion(2.63 ± 2.18 mg/L) were significantly higher compared to those of healthy subjects(1.25 ± 1.40 mg/L and 1.11 ± 1.10 mg/L,respectively,P < 0.05).UIC(g/mol) values were also higher in patients,but the differences were significant only for UIC at 6 *** positive correlation(P < 0.05) was found between the CDAI and IP,assessed by SIC at 3 h(r = 0.60) and 6 h(r = 0.74) after the *** comparison to controls,SIC and UIC of UC patients were higher in the two studied periods,but the differences were significant at 6 h *** higher values of SIC(P < 0.05) were found in patients with severe endoscopic activity of UC compared to those of patients with mild and moderate activity(3.68 ± 3.18 vs 0.92 ± 0.69 mg/L).CONCLUSION:Serum levels of iohexol at 3 h and 6 h after its ingestion reflect increased IP,which is related to the disease activity in patients with IBD.
