Since the introduction of percutaneous transluminal coronary angioplasty, restenosis has remained the most challenging problem facing interventional cardiologist. Intravascular radiation is a feasible and promising adjunctive therapy in restenosis treatment by suppressing both neointimal proliferation and constrictive remodeling, while there are growing concerns about its long-term effects and complications in clinical perspectives as well as dosing and paradoxical stimulation. Current comments on them may well favor the choice of comprehensive treatment protocol for clinicians.

3.Stenting versus Bypass Surgery for the Treatment of Left Main Coronary Artery Disease.
Yonsei Medical Journal 2009;50(6):739-743
Based on data comparing coronary-artery bypass grafting (CABG) with medical therapy, the current guidelines recommend CABG as the treatment of choice for patients with left main coronary artery (LMCA) disease. Percutaneous coronary intervention (PCI) can be selectively performed in patients who are candidates for revascularization but who are ineligible for CABG. Current evidence indicates that stenting results in mortality and morbidity rates compared favorably with those seen after CABG. Data from several extensive registries and a large clinical trial may have prompted many interventional cardiologists to choose PCI with stenting as an alternative treatment option for such patients. In addition, these data may inform future guidelines and support the need for well-designed, adequately powered, prospective, randomized trials comparing the two revascularization strategies.

Iliac artery rupture is a rare complication of post-stenting angioplasty and can lead to massive life-threatening haemorrhage. Conventional surgery can not repair the damaged vessel easily and may cause substantial blood loss and high operative morbidity and mortality. We report our experience with a self-expanding covered endoprosthesis for endovascular repair of the rupture of an iliac artery caused by stenting angioplasty.

Thrombotic thrombocytopenic purpura (TTP) is a rapidly progressive hematological syndrome defined by the pentad of thrombocytopenia, microangiopathic hemolytic anemia, neurologic abnormalities, fever and renal dysfunction. TTP has been associated with major surgical procedures and specific medications. However, there is no known previously reported case in which acute TTP occurred after a percutaneous coronary intervention (PCI). We report a case of TTP after a PCI, that presented with the pentad of symptoms, as well as hepatitis and pancreatitis.

BACKGROUNDThe radial approach has been increasingly used as an alternative to femoral access. And more procedures using repeated transradial coronary intervention (r-TRI) are performed. However, few data about r-TRI has been obtained. Therefore, we investigated the safety and feasibility of r-TRI using the same route.
METHODSA total of 423 consecutive eligible patients undergoing r-TRI were enrolled in the r-TRI group, and 846 patients with initial TRI (i-TRI) were assigned to the i-TRI group in a 2:1 matching ratio compared to r-TRI group. The primary endpoint included the success rate of the procedure and the incidence of vascular related complications.
RESULTSThe baseline clinical characteristics in the two groups were comparable. The success rate of procedures in the r-TRI and i-TRI was similar (96.0% vs. 97.5%, P = 0.130). In subgroup analysis (coronary angiography only or angiography with pecutaneous coronary intervention), similar results were also observed. The puncture numbers and incidence of radial artery spasm in the r-TRI group were significantly higher than in the i-TRI group (P = 0.024 and P < 0.001, respectively). The other procedural outcomes in the two groups were identical. With respect to the incidence of overall vascular related complication and independent events, there were no significant differences in spite of a higher incidence of radial artery occlusion (RAO) in the r-TRI group (RAO: 1.2% vs. 0.7%, P = 0.521). The patients in the i-TRI group had more comfortable feeling than patients in the r-TRI group (P = 0.001).
CONCLUSIONSR-TRI produces a comparable procedure success rate and incidence of vascular complication when compared to i-TRI. It should be considered as an acceptable and safe procedure.
