Introduction: The relationship of pericardial and periaortic adipose tissue with coronary artery disease (CAD) and the significance of this relationship were investigated., Methods: The present study included 323 subjects, with or without cardiac symptoms, who underwent multislice computed tomography coronary angiography between May 2009 and January 2013. Patients were divided into two groups according to the mean values of pericardial adipose tissue volume (PCFV) and periaortic adipose tissue volume (PAFV). In the grouping based on PCFV, subjects with PCFV<157.7 cm3 comprised Group 1, and those with PCFV≥157.7 cm³ comprised Group 2. According to PAFV values, Group 1 consisted of subjects with PAFV<24.3 cm³, and Group 2 subjects with PAFV≥24.3 cm³. The relationship of CAD with each of PCFV and PAFV was investigated., Results: Based on PCFV measurements, there were 79 (43.6%) and 113 (79.6%) patients with CAD in Groups 1 and 2, respectively. Based on PAFV measurements, Group 1 comprised 90 (48.1%) and Group 2 comprised 102 (75%) CAD patients., Conclusions: In both groupings, the prevalence of CAD was significantly higher in Group 2 versus Group 1 (p<0.01 for both). There was a significant relationship between CAD and PAFV (p<0.05), but the relation between CAD and PCFV was more significant (p<0.01).

Background: Some risk factors for atherosclerosis are followed by non-alcoholic fatty liver disease (NAFLD). We wanted to use Multislice computed tomography (MSCT) as technique for searching relationship between NAFLD and coronary artery disease (CAD)., Objective: The relationship between NAFLD and CAD was investigated using MSCT., Methods: A total of 372 individuals with or without cardiac symptoms who had undergone MSCT angiography were included in the study. The patients were divided into two groups according to the presence of NAFLD. Coronary artery segments were visually evaluated via MSCT angiography. Based on the coronary artery stenosis degree, those with no or minimal plaques were considered normal, whereas those who had stenosis of less than 50% and at least one plaque were considered to have non-obstructive coronary artery disease (non-obsCAD). The patients who had at least one plaque and coronary artery stenosis of 50% or more were considered to have obstructive coronary artery disease (obsCAD). NAFLD was determined according to the MSCT protocol, using the liver density., Results: According to the liver density, the number of patients with non-alcoholic fatty liver disease (group 1) was 204 (149 males, 54.8%) and with normal liver (group 2) was 168 (95 males, 45.2%). There were 50 (24.5%) non-obsCAD and 57 (27.9%) obsCAD cases in Group 1, and 39 (23.2%) non-obsCAD and 23 (13.7%) obsCAD cases in Group 2., Conclusions: The present study using MSCT demonstrated that the frequency of coronary artery disease in patients with NAFDL was significantly higher than that of patients without NAFDL.

Objective: We investigated the effects of pedicled and semiskeletonized left internal mammary artery (LIMA) harvesting techniques on postoperative drainage in patients subjected to off-pump CABG, ignoring other advantages or disadvantages of those techniques. Methods: The present study comprises a total of 160 subjects that underwent coronary artery bypass surgery in our clinic. Data were collected consecutively and retrospectively. An attempt was made to have similar groups in terms of demographic characteristics. Patients that underwent off-pump coronary artery bypass surgery by two surgical teams which differed only in LIMA harvesting technique were dichotomized and compared according to these techniques. The first group (Group 1) consisted of patients in whom LIMA was harvested with surrounding tissues using the pedicled technique. The second group (Group 2) consisted of patients in whom LIMA was harvested using the semiskeletonized technique, with the veins separated from surrounding connective tissues. Results: The mean amount of drainage in the first 24 hours was 706.1±234.2 ml vs. 591±258.8 ml (Group 1 vs. Group 2; P=0.005), the mean amount of drainage in the second 24 hours was 270±133.6 ml vs. 189.4±140.4 ml (Group 1 vs. Group 2; P<0.001), and the mean amount of total drainage was determined to be 976.1±306.9 ml vs. 781.2±335.5 ml (Group 1 vs. Group 2; P<0.001). Conclusion: It was observed that semiskeletonized LIMA presents reduced amount of postoperative drainage in the first and second 24-hour periods and total amount of drainage than pedicled LIMA, independent of pleural integrity.
