Purpose: This study aimed at identifying factors related to persistent postoperative pain after cardiac surgery and estimating their effect sizes. Methods: The literature search and selection was conducted in four different databases (CINAHL, Cochrane Library, PubMed, and PQDT) using the Preferred Reporting Items for Systematic Review and Meta-Analysis Statement. A total of 14 studies met the inclusion criteria and were systematically reviewed. For the meta-analysis, R was used to analyze 30 effect sizes of for both individual and operative factors as well as publication biases from a total of nine studies. Results: The meta-analysis revealed that persistent postoperative pain after cardiac surgery was related to one individual factor (gender) and two operative factors (acute postoperative pain and use of the internal mammary artery). Operative factors (OR=5.26) had a larger effect size than individual factors (OR=1.53). Conclusion: Female gender, acute pain after surgery, and use of the internal mammary artery are related factors to persistent postoperative pain. The development of interventions focusing on modifiable related factors, such as acute postoperative pain, may help to minimize or prevent PPP after cardiac surgery.

The radial artery as a graft for myocardial revascularization was introduced by Carpentier in the early 1970s. Mid-term results were unfortunately discoura ing, and the clinical experience with this graft was interrupted. At the end of the 1980s, these authors reproposed the same arterial conduit with more satisfying results, because of improved technique and pharmacological management of the graft. Between October 1994 and July 1995, 36 patients underwent myocardial revascularization with a radial artery graft in Seiong General Hospital. Left internal mammary artery was concomitantly used as a pedicled Vift in 34 patients. Fifteen patients (42%) had a complete arterial waft revascularization. A total of 12) distal anastomoses were performed (average 3.4 per patient), including 36 left internal mammary artery wafts (two sequential in 2 patients), and 23 saphenous vein grafts. The remaining 64 distal anastomoses were perFormed with radial artery grafts (mean 1.8 per patient). The radial arteries were anastomosed to the circumflex (n=38), diagonal (n= 18), right coronary(n=G), and left anterior descending coronary artery(n=2). The percent ge of radial artery graft anastomoses (64) to the total anastomoses(123) was 52%. The radial artery was used as a single graft in 10 patients, as a sequential graft in 25 patients, and two grafts in 1 patient. Twenty patients underwent associated procedures coronary endarterectomy (14), coronary artery patch angioplasty (4), mitral valve repair (1), and repair of ventricular septal rupture (1). One patient died of low cardiac output syndrome and the others had no perioperative myocardial infarction. There are no ischemic and functional complications in the arm or hand aftcr removal of the radial artery. Only 1 patient required reexploration of the am, for the hematoma evacuation, and 2 patients complained transient thumb dysesthesia of the side of the havested arm. This dysesthesia improved within one month. Postoperative angiovaphic controls were obtained in 11 patients(31%) postoperative 79 to 210 days (mean 126 days). The patency rate were as follows : left internal mammary artery (100%), saphcnous vein (100%), and radial artery(95%). We concluded that the radial artery is useful alternative graft, but long term clinical and angiographic studies are required to derterminc whether wider application is warranted.

From July 1992 through January 1993, 11 patients with unstable angina received aorto-coronary bypass surgery at Dong-A University Hospital. There were 5 males and 6 females whose age ranged from 36 to 76 years old. Of the 11 patients, 3 were Functional class IL 5 were Functional class 111.3 were Functional class IV. Preoperative coronary angiography showed a significant stenosis of the left anterior descending artery in 9 cases, of its diagonal branch in I case, of the circumfiex artery in 3 cases, and of its obtuse marginal branch in 2 cases, of the right coronary artery in 4 cases, and of left main coronary artery in 3 cases. There were 4 cases of single vessel disease, 1 double vessel disease, 3 triple vessel disease and 3 left main disease. A single graft was placed in 1 patient, a double graft in 5, a triple graft in 2, and a quadriple graft in 3 patients. Left internal mammary artery plus saphenous vein graft were used in 4 patients. Postoperative complications were mediastinitis in 1, sternal instability in 2, pneumonia in 1, arrythmia in I case.

This second report in the series on coronary artery bypass presents the authors experience and personal views on the internal thoracic artery (ITA) which date to 1966. There has been a very gradual evolution in the acceptance of this conduit which was initially compared with the saphenous vein and viewed as an improbable alternative to it. As is common with concepts and techniques which are 'outside the box' there was skepticism and criticism of this new conduit which was more difficult and time consuming to harvest for the surgeon who had to do it all. It was viewed as small, fragile, spastic and its flow capacity was questioned. Only a few surgeons employed it because of these issues and some of them would frequently graft it to the diagonal artery as it was thought not to supply adequate flow for the left anterior descending unless it was small. After a decade, angiographic data revealed superior patency to vein grafts. Even this evidence and survival benefit reported a few years later did not convince many surgeons that their concerns about limitations justified its use. Thus widespread adaption of the ITA as the conduit of choice for the anterior descending required another decade and bilateral use is only now expanding to more than 5% of patients in the US and somewhat faster in other countries.

A 47-year-old male with hypertension, diabetes mellitus and heavy smoking, but no anginal symptoms, presented with claudication of the lower extremities. Extremity angiography with coronary angiography revealed peripheral arterial lesions including a left subclavian artery occlusion with coronary artery disease. The patient underwent an initial off-pump coronary artery bypass with an ascending aorto-axillary bypass. The right internal mammary artery was anastomosed to the left anterior descending coronary artery. The greater saphenous vein graft was connected from the ascending aorto-axillary bypass graft to the diagonal branch. At postoperative day 18, femorofemoral and bilateral femoropopliteal bypasses were performed. We report a case of the combined repair of coronary artery disease and a left subclavian artery occlusion.

background: The right gastroepiploic artery(RGEA) has been use in coronary artery bypass grafting from 1987. The RGEA is the most useful arterial conduit in coronary artery bypass grafting(CABG) followed by the internal mammary artery, Materials and method: From Septermber 1998 to February 1999 the RGEA was used for coronary artery bypass grafting in 11 patients 10 males and 1 female. Postoperative angiography was performed in all of the patients before discharge Result: Early patent rate of the RGEA was 100%. The flow competition of the REGA graft was seen in 4 patients(36.4%) The flow pattern war RGEA dependent type in the inner diameter of the recipient coronary artery 1.5 mm the inner diameter of the RGEA 2.5 mm and the rtio of inner diameter of the RGEA and the recipient coronary artery 1(p<0.05) Conclusion : Early results of CABG with RGEA was satisfactory. However the RGEA graft has a tendency of flow competition in relation to the inner diameter of graft. Preoperative angiographic evaluation for RGEA and meticulous operative technique are required for a good surgical results.

Myocardial abscess usually occurs as a complication of infective endocarditis or overwhelming septicemia. Coronary artery occlusion caused by myocardial abscess has been rarely reported. A 61-year-old man presented with fever and chill that developed 6 weeks prior to admission. He had a history of cardiopulmonary resuscitation for ventricular fibrillation and cardiac arrest 4 weeks prior to admission. Echocardiography showed a 3xfcm sized mass in the area of the right atrioventricular groove and coronary angiography showed complete occlusion of the proximal right coronary artery. Under the diagnosis of myocardial infarction complicating myocardial abscess, debridement of abscess and coronary artery bypass grafting with right internal mammary artery to distal right coronary artery was performed. Culture from the abscess cavity demonstrated Salmonella arizona.

Background: The safety and efficacy of arterial composite grafts for total arterial revascularization have been demonstrated. The saphenous vein (SV) is a widely used graft because of its accessibility, sufficient length, and ease of manipulation. Our aim was to compare mid-term outcomes of saphenous vein Y-grafts with radial artery Y-grafts joined by anastomosis to the left internal thoracic artery. Materials and Methods: Records of off-pump coronary artery bypass grafting with composite Y-grafts based on the left internal thoracic artery technique in 552 patients were analyzed retrospectively. After propensity score matching, 79 radial arterial (RA) composite grafts (RA group) and 79 saphenous vein composite grafts (SV group) were compared. The duration of mean follow-up was $24.6{\pm}14.6$ months (range, 1 to 55 months). Results: There were no differences in surgical mortality, all-cause mortality, or morbidity among the groups. Rates of 4-year survival were 91.7% and 96.3% in the RA and SV groups, respectively (p=0.519). The coronary reintervention-free survival rate and freedom from major adverse cardiovascular or cerebrovascular events were similar in the two groups (p=0.685, p=0.564). Conclusion: Construction of composite Y-grafts using the radial artery or saphenous vein showed similar mid-term results. Long-term follow-up and randomized trials will be needed to confirm our present conclusions.

The pulmonary sequestration is rare congenital pulmonary disease with nonfunctioning lung tissue supplied by aberrant arteries arising from systemic arteries-thoracic aorta, subclavian artery, innominate artery, internal mammary artery, etc. In our country, only 23 cases were reported previously and the majority was intralobar pulmonary sequestration except 2 cases. The patient was 17 year-old man and admitted due to intermittent cough, productive sputum and fever for 8 years. On simple chest P \ulcornerA view, multiple cysts with air-fluid levels were located at left lower lobe area. Aortogram revealed two aberrant arteries arising from thoracic aorta just above the diaphragm. On the operative field, the arteries were 0.7 and 0.3 cm in diameter. Left lower lobectomy was done with ligation of aberrant arteries. The patient was recovered and discharged uneventfully.
