  • Efficacy and safety of catheter-directed thrombolysis and anticoagulation for deep vein thrombosis: a meta analysis

    ObjectivesTo systematically review the efficacy and safety of catheter-directed thrombolysis (CDT) versus anti-coagulation (AC) for deep vein thrombosis (DVT). MethodsWe searched PubMed, EMbase, The Cochrane Library, Web of Science, WanFang Data and CNKI databases to collect randomized clinical trials (RCTs) about CDT versus AC for DVT from inception to March 2018. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 5 RCTs and 989 patients were included. Meta-analysis showed that there was no significant difference between the two group in incidence of post-thrombotic syndrome (RR=0.73, 95%CI 0.49 to 1.09, P=0.13), iliofemoral venous patency rate (RR=2.57, 95%CI 0.59 to 11.24, P=0.21), bleeding (RR=2.03, 95%CI 0.50 to 8.28, P=0.32), severe bleeding (RR=1.77, 95%CI 0.91 to 3.42, P=0.09) and recurrence rate of venous thromboembolism (RR=1.00, 95%CI 0.42 to 2.36, P=0.99). However, the incidence of moderate-severe PTS decreased in CDT group was lower than that in the control group (RR=0.70, 95%CI 0.53 to 0.92, P=0.01). ConclusionsCompared with the control group, catheter-directed thrombolysis does not reduce the incidence of PTS and VTE recurrence rate, cannot improve the long-term patency of the iliofemoral vein, yet can prevent the occurrence of moderate to severe PTS. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.

  • Early and Mid-term Follow-up Outcomes of“One-stop” Hybrid Coronary Revascularization for Patients with Multivessel Coronary Artery Disease

    Abstract: Objectives To evaluate the early and mid-term follow-up outcomes of “one-stop” hybrid coronary revascularization strategy for patients with multivessel coronary artery disease. Methods From June 2007 to December 2009, 104 consecutive patients underwent “one-stop”hybrid coronary revascularization in Fu Wai Hospital. There were 93 male patients and 11 female patients with mean age of (61.8±10.2)years(ranging from 35 to 81 years). All the patients had multivessel coronary artery disease including left anterior descending (LAD)coronary artery stenosis, and underwent “one-stop”hybrid coronary revascularization. “One-stop”hybrid procedure was first performed through a lower partial sternotomy at the second left intercostal space. The distal anastomosis of in situ left internal mammary artery (LIMA)to LAD graft was completed. Angiography was performed immediately to confirm patency of the LIMA graft after closure of the thorax. A 300 mg loading dose of clopidogrel was administered through a nasogastric tube after confirmation of LIMA graft patency. Intravenous unfractionated heparin was administered to obtain an activated clotting time of greater than 250 s. Then percutaneous coronary intervention(PCI)was performed on the non-LAD lesions. Results All the patients underwent“one-stop”hybrid coronary revascularization including grafted LIMA to LAD,and one hundred and ninety one drug eluting stents and three bare metal stents were used for other non-LAD lesions. No death event occurred during surgery and in hospital. All the patients were followed up for a mean duration of 1.5 years. There was no myocardial infarction, neurologic event or death occurred during follow-up except one patient with stent stenosis who was treated by PCI. Conclusion “One-stop” hybrid coronary revascularization is a feasible and safe alternative for patients with multivessel coronary artery disease.

  • Characteristics and clinical significance of irreducible Pipkin type Ⅰ and Ⅱ femoral head fracture-dislocations

    Objective To summarize the characteristics and clinical significance of irreducible Pipkin type Ⅰ and Ⅱ femoral head fracture-dislocations. Methods The clinical data of 4 patients with irreducible Pipkin type Ⅰ and Ⅱ femoral head fracture-dislocations between January 2010 and December 2019 were collected. There were 2 males and 2 females and the age ranged from 24 to 41 years, with an average age of 33.5 years. The cause of injury included traffic accident in 3 cases and falling in 1 case. Pipkin classification was 2 cases of type Ⅰ and 2 cases of type Ⅱ. The time from injury to operation was 1-2 days. The clinical features were that the hip joint of the affected limb was in a locked position, and the passive range of motion was poor. The affected limb was slightly flexed at the hip joint and shortened, in a state of neutral position or slight adduction and internal rotation. The imaging data suggested that the femoral head dislocated backward and upward, and the hard cortex of the posterior edge of the acetabulum was embedded in the cancellous bone of the femoral head, and the two were compressed and incarcerated. Patients of cases 1-3 underwent closed reduction of hip dislocation 1-2 times at 3, 1, and 3 hours after injury respectively, and femoral neck fracture occurred. The injury types changed to Pipkin type Ⅲ, and open reduction and internal fixation were performed. Patient of case 4 did not undergo closed reduction, but underwent open reduction and internal fixation directly. Results Patients of cases 1-3 were followed up 14, 17, and 12 months, respectively. They developed osteonecrosis of the femoral head at 9, 5, and 10 months after operation respectively, and all underwent total hip arthroplasty. Patient of case 4 was followed up 24 months and had no hip pain and limited mobility; the imaging data indicated that the internal fixator position was good and the fracture healed; no collapse or deformation of the femoral head was seen, and no osteonecrosis of the femoral head occurred. Conclusion Clinicians need to improve their understanding of the unique clinical features and imaging findings of irreducible Pipkin type Ⅰ and Ⅱ femoral head fracture-dislocations. It is suggested that open reduction and simultaneous fixation of femoral head fracture should be directly used to reduce the incidence of osteonecrosis of the femoral head.
