Objective To evaluate the clinical efficacy of coroflex (BRAUN, Germany) intracoronary stent. Methods To retrospectively analyze the immediate angiographic and clinical follow-up outcomes of 81 patients (pts) receiving coroflex intracoronary stenting. Results 88 coroflex intracoronary stents were implanted in 81 pts. According to ACC/AHA classification, 38 lesions were type A-B 1, 50 lesions were type B 2-C. 52 lesions were de novo, 22 were suboptimal results after PTCA and 14 lesions were bailout for dissections. Stent deployment was successful in 82/88 (93.2%). High-pressure (16-18 atm) balloon was used for stent deployment in 3 lesions with severe calcification. Dissection was occurred at distal of stent in 2 lesions but no inducing flow reduction. Angiography showed TIMI 2 grade after intracoronary stenting in 1 diffused lesion. There were no adverse events occurred during hospital stay. Clinical follow-up of in 75 pts were conducted for 7.5?3.0 (3-13) months, there were no cardiac death or myocardial infarction reported. Complain of angina (CCS class Ⅰ) occurred in 17 pts (22.7%). Repeat angiography was performed in 7 pts, there were 2 in-stent restenosis with successful revascularization. Conclusion Coroflex intracoronary stenting appears to be safe and effective in the treatment of coronary lesions with favorable outcomes.

150?mol/L who underwent PTCA and/or coronary stenting were included (renal dysfunction group). Another 25 age and sex matched patients who had normal serum creatinine level and received coronary intervention at the same period were served as a control group. The status of coronary disease, procedural complications and long term prognosis were compared between the two groups. Results The number of patients with multi vessel disease (72% vs 48%, P

75mmHg) underwent PBMV using standard Inoue technique, and the changes in clinical functional status and echo Doppler pulmonary systolic pressure during follow up were assessed. Results PBMV was successful in 39 patients. Immediately after the procedure, mitral valve area increased from (0.83?0.12)cm 2 to (1.75?0.11)cm 2 ,pulmonary systolic pressure decreased from (85?7)mmHg to (61?13)mmHg (all P

Objective To evaluate the feasibility, safety and efficacy of ACS MULTI LINK PENTA (PENTA) stent in patients with coronary artery disease.Methods From March to June 2002, thirty PENTA stents were implanted in 28 patients with 30 de novo lesions. For each patient the demographic, interventional and mean 3 month follow up informations were recorded. Results Almost two thirds of patients suffered from hypertension(61%) and half experienced unstable angina (53%). Most target lesions(67%) had unfavorable morphological characteristics (type B2 or C). No stent deployment failure occurred as well as acute or subacute stent thromobis.The major branches compromised after stenting were only in 2 patients. During floow up,no MACE occurred, except reoccurrence of chest pain in 2 patients (7%). Conclusions The PENTA stent appears to be safe and effective in treating coronary artery disease.

50% and was classified as in-stent if inside stent or in-segment if located within the stented segment plus the 5 mm segments distal or proximal to the stent margins. Results Among the 8 patients included in this analysis, 5 had in-segment restenosis and 3 had in-stent restenosis (2 were not real in-stent restenosis and were just due to underexpansion). IVUS showed all restenosis occurred as localized lesion. Conclusion Restenosis after drug-eluting stents implantation is frequently associated with local trauma outside the stented segment and incomplete lesion coverage by the drug-eluting stent. Restenosis usually occurs proximal to the stent and presents as a localized lesion.

Objective To evaluate the efficacy and safety of Firebird drug-eluting stent (DES) in the treatment of de novo native coronary artery lesions.Methods 60 patients underwent coronary artery stenting with Firebird DES (Firebird group), 52 patients with Cypher DES (Cypher group) and another 20 patents with Mustang bare stents (Mustang group). The instant and short term follow-up outcomes were compared among the three groups. Results The procedural successful rates (98.3%vs 100.0%vs 100.0%), nitrate cessation (32.1%vs 33.3%vs 29.4% ), re-admission(5.6%vs8.3%vs11.7%) and follow-up rates (88.3%vs 92.3%vs 85.0%) did not significantly differ among the three groups. As compared with Firebird group, patients in Mustang group had more MACE(17.6%vs 0), higher occurrence rates of restenosis(17.6%vs 0) and target vessel revascularization(17.6%vs 0)(P

Objective To assess

Objective To evaluate the long-term effect of coronary stenting in young coronary artery diseased patients (45) undergoing coronary stenting were chosen randomly as the control group. Comparison the general characteristics, coronary angiographies, interventional and follow-up informations between the two groups was undertaken. Results Comparing with the control group, the young group patients presented much more myocardial infarctions (68% vs 35%, P

Objective To explore the principle and methods of surgical management of acute distal colon obstruction caused by colorectal cancer.Methods The data of the cases who received one stage resection in our hospital were analyzed retrospectively,and their surgical management was evaluated comprehensively.Results 34 patients received one stage resection and anastomosis and 6 received delayed anastomosis.All the patients were cured,and no anastomosis fistula or other complications occurred except for 3 cases who were complicated with infection.Conclusion One stage resection and anastomosis was safe for the patients of colorectal cancer complicated with acute disatal colon obstruction as long as the indications were determined appropriately.Colonic irrigation during the operation is essential for one stage anastomosis.
