Objective: The purpose of this study was to show the association between oxidative stress and deep venous thrombosis (DVT) by determining total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) values in patients with DVT and to take precautionary measures to balance oxidative status. Methods: TOS, TAS and OSI levels in serum from 52 individuals with DVT and 45 without DVT were compared. Results: TOS and OSI levels were significantly higher in patients with DVT compared with the control group (p<0.0001), but no difference was observed in TAS levels (p=0.118). The patient group was divided into two subgroups, idiopathic and secondary DVT. TOS and OSI levels were significantly higher patients with both idiopathic DVT and secondary DVT compared to the control group (p<0.0001). TAS levels were significantly higher in patients with idiopathic DVT than in the control group, but no difference was observed in the patients with secondary DVT. Conclusion: Specificity and sensitivity values obtained from the receiver operating characteristic (ROC) curve show that TOS and OSI are both markers that can be used in the diagnosis of DVT. Also, determination of oxidative stress markers may guide clinicians to take necessary precautions to balance oxidative stress in the patients.

Objectives The purpose of this retrospective study was to compare the mean platelet volume between the patients with acute deep vein thrombosis (DVT) and control subjects. Methods Data were collected retrospectively from the patients' medical records. The study group consisted of 110 patients with newly diagnosed acute DVT in the lower extremities. An age, gender, and body mass index-matched control group consisted of 98 patients with normal duplex ultrasound findings. We compared the mean platelet volume in patients with acute DVT and control participants. Results There was no significant difference between the study and control groups in mean platelet volume (8.8 +/- 1.6 vs 8.7 +/- 1.3 fl, respectively; p>0.05). Age (p=0.899), body mass index (p=0.43), gender (p=0.466), and platelet count (p=0.886) were statistically similar in both groups. Conclusions There was no significant difference in mean platelet volume between patients with acute DVT and the control group. According to our result, we propose that mean platelet volume should not be considered as an index of acute DVT.
