ABSTRACT
Objective To explore the efficacy of multiple interventional models combined through anterior tibial veins approach in treatment of acute deep venous thrombosis (DVT).Methods The clinical data and the imaging materials of 10 patients with acute DVT were analyzed retrospectively,and the interventional treatment strategies were discussed.Results The percutaneous mechanical thrombectomy (PMT) was performed after a temporary inferior vena cava filter implanted in all patients,and thrombus clearance rate of grade Ⅲ was obtained in 7 patients while 3 patients reached grade Ⅱ criteria.There were 7 patients underwent angioplasty,then the inferior vena cava filter was retrieved during the same procedure in 5 patients while 4 patients in the second stage and 1 patient rejected to retrieve the filter.All swelling limbs alleviated significantly after those procedures.There was no critical complications occured.The total hospital stay ranged from 4 to 7 days,with a mean time of (6.00±0.94) days.All patients were followed up with a mean time of (3.60± 1.84) months (ranged from 1 to 6 months).No thrombus recurrences of the previously affected vessels were reported.Conclusion The multiple interventional models combined via anterior tibial veins for acute DVT is simple,safe and effective,combined with mechanical thrombectomy device can reduce thrombus burden quickly,and combined with angioplasty can consolidate the therapeutic effect,all those methods combined can shorten the overall hospitalization time.
ABSTRACT
Objective To investigate pulmonary embolism (PE) clinical characteristics, the first clinical symptoms, and risk factors.Methods Incidence trends, clinical manifestations, etiology and inducing factors of 459 PE cases were analyzed retrospectively.Results For women the two peak period of PE incidence are 20-25 years of age and 60-70 years of age, for men are 20-30 years and 60-70 years;For both men and women PE incidence is peaked at 40-65 years of age.Circular distribution statistics showed the peak incidence of PE falls from November 30 through April 4, roughly in seasons of winter and spring.Dyspnea, chest distress, were among the most common symptoms (64.04％).Pulmonary infarction trilogy accounted for only 8.50％.Surgery, trauma, fracture were the primary causes for PE (44.88％), with tumor accounting for 13.0％.The veins affected by DVT are plexus venosus leg muscle, femora popliteal vein, iliac veins, tibial and peroneal veins.Conclusions The incidence of PE has obvious central tendency of age, season.Clinical symptoms are varied and non-specific.Surgery, trauma and fractures are the primary cause of PE, tumor is an independent risk factor for PE.
