Objective To discuss how is the perinatal infant’s prognosis influenced by different cardiac function and types of heart disease in pregnant women with heart disease, and to check the importance of antenatal examination. Method Retrospective analyses were conducted on the clinical records of 102 pregnant women hospitalized due to heart disease from February 2002 to February 2011 in the First Affiliated Hospital of Xinjiang Medical University. According to the level of cardiac function, 61 patients were divided into the Level I-II group and the other 41 patients were in the Level III-IV group. Results Of all cases, 38 were congenital heart disease (37.25%), followed by 22 arrhythmia (21.57%), 17 rheumatic heart disease (16.67%), 15 perinatal cardiomyopathy (14.71%), 7 hypertensive heart disease and 3 other types of heart disease. The average gestational weeks were shorter and the neonate’s weight was lower in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the incidence of premature delivery, low birth weight infant at normal gestational age, neonatal asphyxia and perinatal mortality was higher in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the rate of regular antenatal examination was higher in the Level III-IV group than the Level I-II group, with a significant difference (P=0.008); and there were significant differences between the regular and irregular examination groups in the incidence of premature delivery and low birth weight infant at normal gestational age (Plt;0.05), but no significant differences were found in the incidence of asphyxia and perinatal mortality (Pgt;0.05). Conclusions Congenital heart disease is the most commonly-seen type in the pregnant women with heart disease. The maternal cardiac function directly impact the prognosis of perinatal infant, and the regular antenatal examination, timely diagnosis and treatment can improve pregnancy outcome.
Objective To evaluate the directional significance of SurgiCase software in free fibula mandibular reconstruction. Methods Between September 2010 and March 2012, 10 patients with mandibular defect underwent free fibula mandibular reconstruction. There were 7 males and 3 females, with an age range of 19-43 years (mean, 27 years). The extent of lesions was 7 cm × 5 cm to 16 cm × 8 cm. In each case, three-dimensional spiral CT scan of the maxilla, mandible, and fibula was obtained before surgery. The CT data were imported into the SurgiCase software and the virtual surgery planning was performed. After that, the mandibular rapid prototyping was made according to customized design. The reconstruction surgery was then carried out using these preoperative data. During actual surgery, the extent of mandibular defect was from 6 cm × 3 cm to 16 cm × 5 cm; the length of fibula which was used to reconstruct mandible was 6-17 cm; and the area of flap was from 6 cm × 5 cm to 16 cm × 6 cm. Results Preoperative data could not be applied because the intraoperative size of tumor was larger than preoperative design in 1 case of mandibular ameloblastoma, and the fibula was shaped according to the actual osteotomy location; operations were performed successfully according to preoperative design in the other 9 patients. The operation time was 5-7 hours (mean, 6 hours). Primary healing of incision was obtained, without early complications. Ten patients were followed up 1 year. At last follow-up, 8 patients were satisfactory with the appearance and 2 patients complained with unsatisfied wide facial pattern. The panoramic radiograghs showed good bone healing. The range of mouth opening was 2.5-3.5 cm. Conclusion SurgiCase software can provide precise data for free fibula mandibular reconstruction during surgery. It can be applied widely in clinic.
