Effectiveness of Venous Stenting for the Treatment of Lower Extremity Chronic Thrombotic Venous Obstruction.

BACKGROUND: Patients with venous hypertension (HTN) have significant morbidity and poor quality of life. Deep venous thrombosis (DVT) and congenital defects that led to chronic outflow blockage are frequent causes of venous HTN. It is known that the venovenous bypass has been the standard method used in the treatment of chronic iliofemoral vein occlusions. Percutaneous recanalization has earlier been shown to be technically possible. With venoplasty and stenting, we used an aggressive endovascular strategy to treat the iliofemoral venous thrombotic occlusion. METHODS: From May 2019 to April 2021, the medical records were reviewed for 63 patients diagnosed with symptomatic iliofemoral thrombotic occlusive disease and treated with venous stenting. The procedures' results were analyzed at Al-Azhar University Hospitals. RESULTS: The medical records of 63 cases (44 women with a median age of 49.52 years), with chronic outflow block of iliofemoral vein segment that were treated with endovascular venous stenting, were reviewed retrospectively. Optimal success was obtained in 56 cases (88.9%). The twelve-month primary, assisted primary, and secondary patency rates were 76.8%, 80.4%, and 87.5%, respectively, while it was 73.2%, 80.4%, and 87.5%, respectively, after 2 years. The procedure-related complication rate was 6.3%. Puncture site hematoma was observed in 2 patients (3.2%). Early (30 days) stent thrombosis occurred in 2 patients (3.2%). Most importantly, there was no procedure-related mortality. CONCLUSIONS: Endovascular treatment with balloon angioplasty and stenting of chronic venous thrombotic occlusions is an effective and safe procedure associated with a high technical rate of success and excellent patency rates. Accordingly, it should be considered the first line in the treatment of symptomatic iliofemoral vein occlusion.

Correlation of serum apelin level with carotid intima-media thickness and insulin resistance in a sample of Egyptian patients with type 2 diabetes mellitus.

Background: Type 2 diabetes mellitus (T2DM) is a growing health problem in Egypt, with a significant impact on morbidity and mortality. Measurement of the carotid Intima-media thickness (CIMT) allows early detection of atherosclerotic blood vessel diseases. Apelin is an adipose tissue-derived hormone that may be associated with insulin resistance (IR). This study aimed to assess the level of serum apelin in patients with T2DM and its relation to IR and CIMT. Materials and Methods: A case-control study was conducted on 60 patients with T2DM and 30 healthy controls. T2DM was diagnosed based on American Diabetes Association criteria. The study was carried out at Al-Zahraa University Hospital, Cairo, Egypt, through the period from June to December 2019. The laboratory investigations included serum apelin and blood glucose hemostasis markers. CIMT was assessed using B-mode ultrasonography. Results: Patients' group had a statistically significant higher apelin level than healthy controls (407.96 ± 291.07 versus 83.32 ± 10.55 ng/dL, P < 0.001). The correlation analysis showed that the serum apelin level correlated positively with glycemic indices, body weight, and waist circumference (P < 0.05). At cutoff value of >96 ng/dL, the serum apelin exhibited a sensitivity of 98.3% and specificity of 96.7%, positive predictive value of 98.1%, and negative predictive value of 96.5%, with a diagnostic accuracy of 95.1%. Serum apelin correlated positively with CIMT (r = 0.296, P = 0.022). Logistic regression analysis showed that systolic and diastolic blood pressures, Homeostasis Model Assessment of IR, and CIMT were independent predictors of serum apelin. Conclusion: Serum apelin may be correlated with the degree of carotid atherosclerosis and hence can be used as a prognostic biomarker.
