Guidewire lost during endovenous intervention.

Central venous catheterization is an important vascular access route used in many operations like open-heart surgery, hemodialysis, multiple trauma patients, total parenteral nutrition, and poor peripheral veins. During central venous catheterization, mechanical complications such as catheter thrombosis, infections, and pneumothorax can develop. In this report, we aimed to present a case of guidewire left unrecognized in venous system after central venous catheterization procedure. The guidewire has been extracted under fluoroscopy guidance. This case emphasizes maintaining and improving patient care and safety by doctor and the team.

Association between lower extremity venous insufficiency and increased choroidal thickness.

PURPOSE: The goal of this study is to investigate the association between the choroid and lower extremity venous insufficiency (LEVI). METHODS: This prospective cross-sectional study includes 56 patients with LEVI and 50 age/sex-similar control subjects. Choroidal thickness (CT) measurements from 5 different points were captured from all participants by optical coherence tomography. In the group with LEVI on physical examination, reflux at the saphenofemoral junction, and the diameter of the great and small saphenous veins were evaluated via color Doppler ultrasonography. RESULTS: The mean subfoveal CT was higher in the varicose group than in the control group (363.04±99.75µm vs. 320.30±73.46µm, P=0.013). In addition, the CTs at the temporal 3mm, temporal 1mm, nasal 1mm, and nasal 3mm distance from the fovea were higher in the LEVI group compared to the controls (for all, P<0.05). There was no correlation between CT and diameter of the great and small saphenous vein in patients with LEVI (for all, P>0.05). However, the great and small saphenous veins of patients with CT above 400µm were observed to be wider in patients with LEVI (P=0.027 and P=0.007, respectively). CONCLUSION: Varicose veins can be a feature of systemic venous pathology. Another component of systemic venous disease may be increased CT. Patients with high CT should be investigated for susceptibility to LEVI.
