Objective To study the methods and skill of vena cava filter placement via the antecubital access. Methods Six patients with DVT (4 males and 2 females, mean age of 62) underwent vena cava filter placement via the antecubital access in Huashan Hospital from Oct. 2004 to May. 2006. The right basilic vein was punctured with the use of micropuncture technique. SNF (Simon nitinol filter, Bard)was inserted through its carrier into the 90-cm-long sheath. The filter was then deployed with a standard fashion in the IVC, 5 cm inferior to the renal vein. Results The filter was once placed successfully in all six patients within average time of 25 min without complications, but with good healing, exclusion of bleeding and no phlebitis. The position of filter was accurate without deviation and no occurrence of pulmonary embolism. Conclusions vena cava filter placement via antecubital access is easy, minimal invasive, no need of lying in bed postoperatively. It is beneficial for DVT patients as an alternative for the contra-indication to femoral venous access.

BACKGROUND:Pedicle screw implantation is a common method to repair many kinds of diseases of the lower cervical spine. Three-dimensional (3D) reconstruction visualization system can be used in order to improve the accuracy of the implant and improve the prognosis.
OBJECTIVE:To investigate the effect of 3D reconstruction visualization system on the accuracy of cervical pedicle screw implantation.
METHODS: The clinical data of 89 patients with cervical spine dislocation, who underwent cervical pedicle screw implantation, were analyzed retrospectively. Patients were divided into control group (46 cases) and observation group (43 cases) according to the navigation method. Patients in the control group underwent C arm X ray two dimensional navigation. Patients in the observation group underwent three-dimensional reconstruction visualization system navigation. Intraoperative placement time was observed, and the accuracy of screw placement was assessed in both groups. The cases were folowed up for 12 months, and the adverse events were recorded and compared.
RESULTS AND CONCLUSION: (1) Intraoperative implantation time was shorter in the observation group than in the control group, but no significant difference was found (P> 0.05). (2) Accuracy rate: There were no three types of nail cases in the observation group, and the accuracy rate was 93% (40/43). In the control group, two cases affected three types of nailing, and the accuracy rate was 81% (37/46). The accuracy rate was significantly higher in the observation group than in the control group (P < 0.05). (3) Postoperative folow-up: None suffered from nerve tissue injury to vertebral artery, blood vessel and spinal cord. The screws of the two groups were in stable condition, without screw breakage or loosening. (4) Results suggested that in lower cervical pedicle nail implantation, 3D reconstruction navigation system can effectively improve the accuracy of screw placement, and does not increase nailing time or lead to adverse events. It is a safe and effective navigation mode.
