Prospective, randomized surgical trials with pre-defined objective measures would be required to further evaluate the clinical importance of these preliminary findings which suggest that TPLO may help stabilize the cranial tibial thrust as originally proposed.

Radiographic lucency surrounding the cup-bone interface does not allow assessment of bone contact with the outer surface or bone ingrowth into the Kyon cup in dogs without clinical problems.

HistoryA 10-year-old spayed female Labrador Retriever was evaluated for lethargy and unwillingness to climb stairs of approximately 4 weeks' duration. On physical examination, manipulation of the cervical portion of the vertebral column elicited signs of discomfort and the dog was reluctant to lift its head. Additionally, there was mild ataxia of all limbs and an intermittent non-weight-bearing lameness of the right fore limb. Survey radiographs of the cervical portion of the vertebral column were obtained (Figure 1). Determine whether additional imaging studies are required, or make your diagnosis from Figure 1-then turn the page * * Figure 1-Right lateral radiographic view of the cervical portion of the vertebral column of a 10-year-old spayed female Labrador Retriever evaluated for lethargy, unwillingness to climb stairs, and mild ataxia of approximately 4 weeks' duration.

Objective: Maternal anxiety negatively affects the fetus. Women awaiting fetal echocardiography (FEcho) report increased anxiety but it is not known if anxiety decreases post-FEcho. Methods: Women answered two questionnaires at the time of FEcho at MSCHONY. The Spielberger State-Trait Anxiety Inventory assessed how subjects feel ''now'' (state) vs how they ''usually feel'' (trait). Separate state and trait anxiety scores ranging from 20 to 80 were calculated; a score ≥ 35 is moderately anxious. A second form recorded pregnancy specific information. Anxiety scores of the preand post-FEcho groups were compared. Results: From 1/07-1/09, 40 pre-FEcho and 44 post-FEcho subjects were enrolled: 58 (69%) were ≥ 35 yrs old, 25 (30%) were primigravid, and 24 (29%) reported a prior miscarriage. There was no group difference in maternal age or parity but prior miscarriage was more common in the pre-FEcho group (42.5% vs 16%, p = 0.007). Among the self-reported indications for FEcho referral, 49 (58%) had an anomaly on a prior test. Neither state nor trait anxiety scores were associated with maternal age, parity, history of miscarriage or known fetal anomaly. The mean state anxiety score of the pre-FEcho group (42.1 ± 15.1) differed from that of the post-FEcho group (35.9 ± 13.0; p = 0.048); there was no difference in trait scores (34.7 ± 10.8 pre vs 35.8 ± 10.6 post; p = 0.63). In the post-FEcho group, FEcho result influenced both state and trait anxiety. Subjects with an abnormal FEcho (N = 12) had higher state (46.8 ± 15.5) and trait (40.9 ± 12.2) anxiety compared with those with a normal FEcho (state 30.8 ± 8.5, p = 0.005; trait 33.3 ± 9.2, p = 0.03, N = 30). There was no difference in mean state anxiety score among the pre-FEcho group and the post-FEcho group with an abnormal FEcho. Conclusions: Women who have had a FEcho report decreased anxiety compared with women awaiting FEcho. Anxiety levels of women awaiting FEcho are similar to those of women post-FEcho who are told there is fetal cardiac anomaly. P25.11 Prenatal diagnosis of isolated ductus arteriosus aneurysm Ob&Gyn, Chosun University, School of Medicine, Gwangju, South KoreaDuctus arteriosus aneurysm is often detected in the late third trimester of the pregnancy. It usually regresses spontaneously in neonatal period. Some postnatal complications such as spontaneous rupture of the aneurysm, compression of the surrounding tissues, infection and sudden death have been reported. We diagnosed ductus arteriosus aneurysm at 37 weeks of gestation. The aneurysmal dilatation of the ductus arteriosus was seen in the three vessels view. A healthy female baby delivered by repeat Cesarean section at 39 weeks of gestation. After delivery, ductus arteriosus aneurysm without shunt was delineated by MDCT and echocardiography.Supporting information can be found in the online version of this abstract. Objective: To examine the performance of early fetal echocardiography in a high-risk population. Methods: This is a retrospective study of all early fetal echocardiograms (fECHO) pe...
