However, during or after this period, some complications can be seen. In this article, branule fractures have been discussed in 7 cases after peripheral vascular catheterisation. Methods: In this review 7 cases which consulted to Gazi University Medical Faculty Department of Cardiovasculary Surgery during January 2007-January 2008 have been evaluated and retrograd analyzed. Results: In 4 patients, the size of the catheters were 20G-32mm, where as in 3 patients, the catheter sizes were 18G-45mm. All the catheters enjection ports were radioopaque. The 7 catheters which have been reported here were broken by the distal side of ports and all the catheters were used more than three days. Catheters were broken while taking off. When the problem occured, all the forreign bodies in intravascular area were identified and documented by using the ultrasonography. Conclusion: If the catheters keeping is doing well, some of the complications can be prevented and patients satisfaction will improve.
