Background and purpose: Despite extensive studies on prevention and management of deep vein thrombosis (DVT), less attention has been paid to chronic venous insufficiency. The persend study aimed to investegite the incidence and clinical signs of post thrombotic syndrome in patients with deep vein thrombosis.
Materials and methods: A descriptive retrospective study was done in patients with DVT from 2010 to 2013 in Rasht, Iran. Informed written consent was taken from the patients who were willing to participate in this research and photolithography was performed. Demographic and clinical information, underlying diseases, and photolithography results were recorded.
Results: A total of 153 lower limbs was evaluated (mean age of the patients: 14 ± 50 years). In most of the samples, the DVT involvement was iliofemoral (43.1%) and the mean time from developing DVT was 2.8 ± 0.83 years. In these patients, the most common symptoms were edema (66%), telangiectasia (47.7%), and pain (43.8%). The majority of the patients had impaired photoplaciographic scores (94.8%). Post-thrombotic syndrome (PTS) was seen in 37 cases (24.19%). There was no significant correlation between incidence of PTS and occurrence of DVT and therapeutic methods.
Conclusion: Understanding the epidemiology, clinical signs of DVT, and follow-up of its complications can be helpful in making appropriate diagnosis and treatment of these patients. In current study, the abundance of PTS was not great, but, edema, telangiectasia, and pain were obseved in most of the patients.
