UNLABELLED: The objective of this study was to investigate the mid term influence of vessel size in clinical and angiographic outcome, after Wiktor stent implantation in arteries larger and smaller than 3 mm. METHOD: A total of 188 stents were implanted in 167 patients divided in two groups. Group 1: stents implanted in arteries smaller than 3 mm, 40 stents in 38 patients. Group 2: in arteries larger than 3 mm. 148 stents in 129 patients. Clinical follow up and a repeated coronary angiographic study were carried out after six months. RESULTS: Angiographic success was achieved in 97% and 98% cases, with clinical success in 92% and 95% respectively. Acute occlusion occurred in 2 patients of group 1 (5%), and in four patients in group 2 (2.7%); one patient died and four patients suffered a non-fatal myocardial infarction. During clinical follow up, nine patients presented a major complication, two in group 1 and seven in group 2 (5.5% vs. 5.6%). Asymptomatic survival was 86% and 84% respectively. In angiographic follow up we observed a restenosis rate of 41% of the patients in group 1 and 25% of those in group 2. Immediate gain was similar in both groups, but late loss (1.06 +/- 0.85 vs 0.97 +/- 0.86) and loss rate (0.60 vs 0.46) were greater in group 1. CONCLUSION: The frequency of stent thrombosis as well as the incidence of restenosis were higher in arteries smaller than 3 mm. No differences were observed in the incidence of major ischemic events.
Synovial sarcomas of the head and neck are rare, fewer than 80 cases having been reported in the literature. A synovial sarcoma of cervical soft tissues presented as a lateral mass in a 51-year-old male and was treated by cervical dissection and radiotherapy. After 24 months the patient is recurrence-free. The histology and origin of synovial sarcomas is discussed.
