Review Comparative Study
Minimally invasive direct coronary artery bypass grafting: a systematic review.
Recently minimally invasive direct coronary artery bypass grafting (MIDCAB) has become an interesting alternative to conventional coronary artery bypass grafting, especially in patients with a high-grade left anterior descending coronary artery (LAD) stenosis unsuitable for balloon angioplasty. Although MIDCAB offers several advantages such as the avoidance of sternotomy and cardiopulmonary bypass, concerns have been raised about the technical accuracy of the anastomoses that can be performed on a beating heart. Therefore, clinical and angiographic outcomes after MIDCAB are the subject of current controversy. ⋯ Clinical outcomes and immediate graft patency after MIDCAB are acceptable. However, long-term follow-up results and further randomized prospective clinical trials comparing this new technique with standard revascularization procedures are needed.

Indications of coronary angioplasty and stenting in 2003: what is left to surgery?
For many years, coronary artery by-pass graft (CABG) remained the only effective treatment of multivessel disease compared to medical treatment. The first technical revolution was in 1977 when Gruentzig introduced balloon percutaneous transluminal coronary angioplasty (PTCA), the 2nd in the 90's with the developments of stents and antiaggregant protocols. The equipment for PTCA became more and more sophisticated, and the skill of cardiologists greater. In the 90's, interventional cardiology played a predominant role in revascularization as the number of CABG decreased at the same time, and emergency CABG for bail out almost disappeared (0% to 0.5%). Systematic stenting decreased the need for repeat revascularization to about 18-20% nowadays in the majority of centers, except in diabetic patients. Despite this fact restenosis remains the pitfall of angioplasty, mostly in diabetic patients presenting multivessel disease in which surgery with "all arterial grafts" gives good long term ⋯ The first studies comparing PTCA and CABG are favourable to surgery (BARI), then late ones using stents (ARTS, ERACI 2) showed that stenting was at least equivalent to CABG, in terms of mortality or serious complications (major acute coronary events, MACE), despite a higher target vessel revascularisation (TVR) mainly due to restenosis in the angioplasty cohort. The same results are observed by stenting a high risk lesion as the unprotected left main stenosis can be, until then treated surgically. However, high volume centers studies treating by PTCA+stent the unprotected left main artery (LMA) shows that the 1 year survival rate is similar to surgery, but always related to a restenosis rate of 20% at 6 months in the stent group, which represents the only significant difference in terms of MACE; the new drug eluting stents lead us to expect, according to SIRIUS and TAXUS II studies, to reduce the restenosis rate, and by the way, the MACE could be dramatically lowered from 50% to 60%. Randomised studies would be necessary, but the extrapolation of the actual data, more particularly results of subgroups with a high risk of restenosis, diabetic patients and small vessels, lead us to think that stenting could come in first intention before surgery if TVR is significantly reduced. A complex anatomy, failed attempted chronic occlusion, several lesions on tortuous vessels, would remain the last surgical indication if CABG provides a more complete revascularization. The impact of these new drugs seems promising. However, we should await early results of studies in diabetic patients and bifurcations. But in high volume experienced centers, CABG indications would be reduced in the future to the technical pitfalls of stenting (complex or tortuous anatomy, chronic occlusions) or to the adverse additional cost of this device, unless reduction of restenosis or TVR could also cancel this extra cost. We expect randomised studies CABG versus stented angioplasty using drug eluting stents to confirm these preliminary data.

Review Case Reports
False aneurysm of perforating branch of the profunda femoris artery after external fixation for a complicated femur fracture.
False aneurysm of the profunda femoris artery rarely occurs and is a serious complication following femur fracture. A 39-year-old man who developed a false aneurysm arising from the perforating branch of the profunda femoris artery following an external fixation for a complicated femur fracture was presented. Clinical diagnosis was confirmed by selective arterial angiography after occurrence of significant hemorrhage and swelling of the injured thigh. ⋯ The patient was discharged on the 10th postoperative day with external fixation. False aneurysm in a branch of the profunda femoris artery is a very rare status following application of the external fixator due to complicated femur fracture. Related literatures and interventions were reviewed on the basis of this case.

The author presents three decades of experience in the management of anterior chest wall deformities. During this period more than 800 operations were performed on patients with pectus excavatum and carinatum. In this series, there was no death and serious complications were rare. ⋯ The present method applied for correction of pectus excavatum utilizes the above principles and a substernal Marlex mesh support with bilateral muscle coverage. For carinatum repair, the author routinely uses positional correction of the sternum and sternal shortening. Patients who have significant pectus deformities should undergo surgical repair, preferably between one and eight years of age.
