BACKGROUND: Restenosis is a major limitation of balloon angioplasty. Recently, new angioplasty devices have been used in an attempt to reduce the restenosis compared with coronary balloon angioplasty. Directional coronary atherectomy effectively dilated the lesion by removal of the atherosclerotic plaque. Therefore, we tried to evaluate immediate and late clinical outcomes after directional coronary atherectomy in the 57 patients with coronary artery disease. METHODS: From October 1991 to March 1997, fifty seven consecutive patients with 69 lesions were treated with directional coronary atherectomy. The patients underwent coronary angiography at pre-intervention, immediately after intervention and at 6 months post-intervention. Restenosis was assessed clinically and by computer-assissted quantitative measurements of luminal dimensions. Patients were requested to undergo coronary angiography at 6 months after directional coronary atherectomy. Angiographic restenosis was defined as more than 50% diameter stenosis by quantitative coronary angiographic analysis. RESULTS: Successful results were achieved in 61 of the 69 lesions(88%) and mean stenosis was reduced from 78.0+/-13.0% to 10.0+/-5.0%. Atherectomy resulted in an increase in minimal lumen diameter from 0.8+/-0.3mm to 3.0+/-0.6mm. Six months follow-up angiogram was obtained in 68% of 50 eligible lesions. The overall angiographic restenosis rate was 32%. Six month clinical follow-up was obtained in 94% of the eligible lesions. The clinical recurrence occured in 38% of the patients. The target lesion revascularization rate was 17%. CONCLUSIONS: Removal of coronary artery plaque with directional atherectomy led to large luminal diameter and six months follow-up angiography shows an overall restenosis rate of 32% However, further clinical study is warranted to evaluate the efficacy of atherectomy with larger numbers of patients.

Coronary pseudo-lesion is an artificial lesion that occurs during percutaneous transluminal coronary angioplasty by an angioplasty guide wire and/or a balloon as a result of a straightening of the vessel curvature. A specific treatment is not required and the condition is completely resolved after removing the angioplasty wire. There are few reports about a pseudo-lesion, particularly in the left circumflex artery. We report two cases of a coronary pseudo-lesion induced by an angioplasty guide wire; one case affecting the left circumflex artery and the other affecting the right coronary artery.

BACKGROUND AND OBJECTIVES: A cutting balloon (CB) is a balloon catheter with 3 or 4 metal blades on its surface used for making controlled endovascular surgical incisions and promising minimal intimal injury. Some reports suggest advantages of the use of CB in the treatment of in-stent restenosis (ISR). The purpose of this study was to report the clinical experience of the use of CB for ISR. SUBJECTS AND METHODS: 28 patients were enrolled in this study. Angiographic success (defined by 40% residual stenosis), in-hospital, 30 days and 6 months clinical outcomes were evaluated. RESULTS: Angiographic success was 92.9% (26/28). The number of inflations and maximal inflation pressure were 2.8+/-0.9 and 10.1+/-1.3 ATM, respectively. The balloon/artery (B/A) ratio was 1.1+/-0.2. There was a case of stent insertion for treating type D dissection and a case of rotational atherectomy for suboptimal result after CB angioplasty. 25 cases underwent analysis through 6 months of clinical follow-up. During the 6-month clinical follow-up, 4 cases of re-PTCA were documented, while MACE during in-hospital time and the subsequent 30 days was 0%. CONCLUSION: Our experience demonstrated that CB can be performed safely and effectively in coronary ISR. Further clinical and angiographic effectiveness are warranted in a large-scale clinical trial.

A 62-year-old man was admitted, and thoracic endovascular aortic repair (TEVAR) procedure was performed to treat an accidentally detected aortic aneurysm, which was 63 mm in diameter. While performing TEVAR, the passage of the stent-graft introducer system was impossible due to the prolapse of the introducer system into a wide-necked aneurysm; this aneurysm was located at the greater curvature of the proximal descending thoracic aorta. In order to advance the introducer system, a compliant balloon was inflated. Thus, we created an artificial wall in the aneurysm with this inflated balloon. Finally, we were able to advance the introducer system into the target zone.
