    Anomaly of the left anterior descending coronary artery arising from the right sinus of valsalva and ventricular septal defect in adult: A rare case
    (Yonsei Univ College Medicine, 2005) Tacar, O; Karadede, A
    Anomaly of the left anterior descending (LAD) coronary artery arising from the right sinus of valsalva is frequently seen with tetralogy of Fallot (TOF). The association of the LAD coronary artery with ventricular septal defect (VSD) is uncommon. We described an anomalous origin of the LAD coronary artery from the right sinus of valsalva with ventricular septal defect in a 38-year-old male patient suffering from atypical angina. The LAD coronary artery arose from the right sinus of valsalva, just next to the right coronary artery. There was a single opening in the membranous part of the interventricular septum. From this case, we suggest that angiography is useful for both documenting anomalies of the LAD coronary artery associated with VSD and for determining the safest surgical procedures.

    Morphology of the lumbar spinal canal in normal adult Turks
    (Yonsei Univ College Medicine, 2003) Tacar, O; Demirant, A; Nas, K; Altindag, O
    Pathological changes can occur in the diameters of the lumbar spinal canal. Therefore, assessing the canal size an important diagnostic procedure. Two hundred plain anterioposterior radiographs of the lumbar spine were examined. The sample consisted of 100 males and 100 females. The transverse diameter of the bony spinal canal (interpedicular distance), which was measured as the minimum distance between the medial surfaces of the pedicles of a given vertebra, was measured. In addition, the transverse diameter of the vertebral body, which was measured as the minimum distance across the waist of the vertebra, was measured. The distances were measured to the nearest one tenth of a millimetere using a Vernier caliper. At all levels (L1-L5) the transverse diameters of the lumbar spinal canal were approximately 1-1.5 mm higher in males than in females. The intersegmental differences increased proximodistally, in both sexes. The ratio of the transverse diameter canal to the width of the vertebra ranged from 0.55 to 0.60 min in both sexes. The distribution of the different lumbar canal types were 47% A, 42% B, 11% C. Additionally, subtypes were determined and classified.

    Replacement of circumflex branch of left coronary artery originating from the right aortic sinus
    (Springer France, 2001) Karadede, A; Tacar, O; Akkus, M
    Replacement of the circumflex branch of the left coronary artery is extremely rare. We conducted a retrospective study to determine the incidence of this anomaly of circumflex branch of the left coronary artery. Two such patients were identified from 850 adults undergoing cardiac catheterization procedures. The circumflex branch of the left coronary artery was replaced by a vessel arising from the right aortic sinus. The course of this vessel was retroaortic. A knowledge of this anomaly is important for coronary artery bypass surgery.
