Predictable Risk Factors of Upper-Extremity Deep Venous Thrombosis in a Level I Trauma Center

Risk Factors of Venous Thromboembolism in Inpatients With Colorectal Cancer in China

To explore the risk factors for venous thromboembolism (VTE) in inpatients with colorectal cancer. The demographic factors, comorbidities, and hematological indices of patients with colorectal cancer treated in our hospital from 2016 to 2021 were collected and recorded. Venous thromboembolism events, including deep venous thrombosis and/or pulmonary embolism, were recorded and the patients were divided into the VTE group and the non-VTE group. We compared clinical data between the two groups and explored risk factors for VTE. Comparing the clinical data of 293 cases of non-VTE group and 235 cases of VTE group, we found significant differences in age, smoking, temperature, amount of blood loss, differentiation degree, peripherally inserted central catheter (PICC), radiotherapy, anemia, infection, white blood cell count, prothrombin time (PT), PT%, prothrombin ratio, international normalized ratio, thrombin time, CA199 and CEA between the two groups (P < 0.05). Logistic regression analysis showed that age (P = 0.0444), temperature (P = 0.0317), amount of blood loss (P = 0.0067), PICC (P < 0.0001), chemotherapy (P = 0.0459), anemia (P = 0.0007), international normalized ratio (P = 0.003) and CA199 (p = 0.0234) were independent risk factors for VTE. Receiver operating characteristic curve analysis showed that the amount of blood loss predicted thrombosis better (AUC = 0.778, P < 0.001), when the cutoff value was 20 mL, the sensitivity was 76.17%, and the specificity was 79.18%, respectively. And PICC predicted thrombosis better (AUC = 0.808, P < 0.001), the sensitivity was 70.21%, and the specificity was 91.47%, respectively. Clinical parameters are associated with VTE in inpatients with colorectal cancer, which will help to guide clinicians to take effective measures to improve the patients' prognosis.

Obesity increases the risk for upper extremity deep vein thrombosis and pulmonary embolism in patients with upper extremity central venous catheters

The morbidity and mortality of deep vein thrombosis (DVT) remain a significant burden for the healthcare system. The aim of this analysis was to examine the association of upper extremity central venous catheter (UECVC) and venous thromboembolism (UEVTE) with increasing body mass index (BMI) in a large database study and to further examine disposition. Inpatient data from the National Inpatient Sample from 2017 to 2019 were used to investigate the effect of obesity on patients diagnosed with DVT of the upper extremity or pulmonary embolism (PE) who had upper extremity venous central line placement. There was a total of 1690 cases of UEVTE and 3202 cases of PE within the sample. There was an increasing odds of UEVTE in the patients with UECVCs with increasing BMI. Patients with a BMI of 30-39, 40-49 and > 50 kg/m² were significantly different than those with BMI of <19 and 20-29 kg/m² in the UECVC group for UEVTE. This study demonstrated increased odds of UEVTE for patients with increased BMI. Practitioners should assume a greater risk for UEVTE and PE in patients with increased BMI when considering CVCs.

Upper extremity deep venous thrombosis prevalence in the NHS Grampian Medical Ambulatory clinic: diagnostic, therapeutic, and prognostic considerations in oncology patients

Introduction

Whilst upper extremity deep vein thromboses (UEDVT) account for approximately 5 to 10% of all cases of DVT, rigorous guidelines regarding diagnosis and management of presenting patients remain to be developed. The association of UEDVT with concurrent asymptomatic pulmonary embolism as well as the first presentation of malignancy deems essential rigorous research and clinical guideline development to ensure optimal patient care.

Methods

This retrospective audit study is the first to provide estimates of UEDVT prevalence in the North-East Deanery main hospital centre, Aberdeen Royal Infirmary (ARI).

Results

Of the 605 patients attending the ARI Ambulatory Emergency Care (AEC) clinic with clinical suspicion of UEDVT, 38 (6.2%) had a confirmatory diagnosis. Underlying malignancy, presence of PICC line, and cardiovascular co-morbidities were identified as common confounding factors. Subclavian vein with concurrent extension to primarily the cephalic vein thrombosis was identified as the most commonly thrombosed venous territories. Importantly, oncology patients were found to have poorer survival outcomes following an UEDVT, in comparison to patients with other significant co-morbidities (cardiovascular, chronic renal disease, inflammatory bowel disease): HR 5.814 (95%CI 1.15, 29.25), p 0.012. Lastly, genetic associations were drawn between patient genetic status as tested for other co-morbidities and prothrombotic cellular cascades, suggesting rigorous VTE assessment in patients identified with congenital or acquired mutations, namely, in CALR, JAK, MSH 2/6, MYC, and FXN.

Conclusions

Overall, this study offers the first report of UEDVT presentations in the UK with no restrictions of patient performance status or underlying co-morbidities and provides a rounded clinical picture of patient characteristics, diagnosis, management, and prognostic associations in view of rigorous guideline development.
