Characteristics of Deep Venous Thrombosis in Isolated Lower Extremity Fractures and Unsolved Problems in Guidelines: A Review of Recent Literature

Efficacy of percutaneous mechanical thrombus removal in acute lower extremity deep venous thrombosis

BACKGROUND

Acute lower extremity deep venous thrombosis (LEDVT) is a common vascular emergency with significant morbidity risks, including post-thrombotic syndrome (PTS) and pulmonary embolism. Traditional treatments like catheter-directed thrombolysis (CDT) often result in variable success rates and complications.

AIM

To investigate the therapeutic efficacy of percutaneous mechanical thrombus removal in acute LEDVT.

METHODS

A retrospective analysis was performed to examine 58 hospitalised patients with acute LEDVT between August 2019 and August 2022. The patients were categorised into the percutaneous mechanical thrombectomy (PMT) group (n = 24) and CDT group (n = 32). The follow-up, safety and treatment outcomes were compared between the two groups. The main observational indexes were venous patency score, thrombus removal effect, complications, hospitalisation duration and PTS.

RESULTS

The venous patency score was 9.04 ± 1.40 in the PMT group and 8.81 ± 1.60 in the CDT group, and the thrombus clearance rate was 100% in both groups. The complication rate was 8.33% in the PMT group and 34.84% in the CDT group, and the difference was statistically significant (P < 0.05). The average hospitalisation duration was 6.54 ± 2.48 days in the PMT group and 8.14 ± 3.56 days in the CDT group. The incidence of PTS was lower in the PMT group than in the CDT group; however, the difference was not statistically significant (P < 0.05).

CONCLUSION

Compared with CDT, treatment of LEDVT via PMT was associated with a better thrombus clearance rate, clinical therapeutic effect and PTS prevention function, but the difference was not statistically significant. Moreover, PMT was associated with a reduced urokinase dosage, shortened hospitalisation duration and reduced incidence of complications, such as infections and small haemorrhages. These results indicate that PMT has substantial beneficial effects in the treatment of LEDVT.

Metaphyseal trauma of the lower extremities in major orthopedic surgery as an independent risk factor for deep vein thrombosis

PURPOSE

Major orthopedic surgeries of the lower extremities, which heavily injure the metaphyseal region, are strongly associated with the risk of developing deep vein thrombosis (DVT). This study aims to investigate the role of metaphyseal trauma as an independent risk factor for DVT.

METHODS

Patients undergoing major orthopedic surgery of the hip and knee had their existing DVT risk factors recorded. Metaphyseal trauma was defined by the extent of bone injury during these surgeries. The samples were categorized into three surgery groups: total arthroplasty group (TA), hemiarthroplasty group (HA), and the open reduction internal fixation group (ORIF). Logistic regression test between significant existing risk factors and surgery groups determines the independent association between risk factors and DVT.

RESULT

The study found a 24.8% incidence of asymptomatic DVT in patients undergoing major orthopedic surgeries, with the highest prevalence (37.2%) in TA, which had the largest extent of metaphyseal trauma and the least existing DVT risk factors. TA showed 6.2 OR and 95% CI (p = 0.036) compared to the other existing risk factor in relation to DVT incidence.

CONCLUSION

Metaphyseal bone trauma in the hip and knee major orthopedic surgery is an independent risk factor for deep vein thrombosis.

Effect of individualized narrative nursing mode on recovery of elderly patients with fracture complicated with cerebrovascular accident

Fractures often occur in elderly patients. Osteoporosis caused by massive loss of calcium ions in the bones of elderly patients can easily lead to femoral fractures after suffering a low- and medium-energy injury. With the gradual entry of the aging society in China, the incidence of senile fracture is also gradually increasing. However, there is no report on the application of personalized narrative nursing to the mental health, cognitive function, and limb function recovery of elderly patients with fracture complicated with cerebrovascular accident, in order to enhance the cognitive level of elderly patients with fracture complicated with cerebrovascular accident. This study was specially conducted with a positive attitude toward the disease and improving the life quality. During July 2018 to July 2021, 80 elderly patients with fracture complicated with cerebrovascular accident cured were selected in our hospital. The patients were arbitrarily classified into an assigned control group (n = 40) and a study group (n = 40). The former received routine nursing, and the latter received personalized narrative nursing mode. The nursing satisfaction, functional independence scale (FIM), self-rating anxiety scale (SAS), self-rating depression scale (SDS), cognitive function, fracture healing time, length of hospital stays, and hospitalization expenses were compared. The study group had a satisfaction rate of 100.00%, while the control group had 87.50%. The nursing satisfaction of the study group was higher (P < .05). After 3 months of nursing, the FIM scores augmented. The FIM scores of upper and lower limbs in the study group were remarkably higher (P < .05). A decrease in SAS and SDS scores was observed. The SAS and SDS scores of the study group were lower (P < .05). Three months after discharge, the cognitive function score augmented. At 3 months after discharge, the study group had a higher cognitive function score (P < .05). The fracture healing time, length of stay, and cost of hospitalization in the study group were lower (P < .05). Personalized narrative nursing model can successfully enhance the mental health and cognitive function of elderly patients with fracture complicated with cerebrovascular accident, enhance the recovery of limb function, promote patients' nursing satisfaction, and alleviate the economic burden.
