Objective To summarize research progress of postoperative complications of transilluminated powered phlebectomy in treatment of varicose veins. Method The clinical and scientific research about the treatment of varicose veins with transilluminated powered phlebectomy in recent years were searched and the progress of the postoperative complications were reviewed. Results With the evolution of surgical techniques and the accumulation of experience, a variety of translucent resection of the postoperative complications such as the cellulitis, wound abscess, hematoma, residual vein, nerve damage reduced. Conclusions From current development trend, incidence of complications after transilluminated powered phlebectomy might continue to decline. It has a potential to become a mainstream surgical technique for varicose veins in future.
ObjectiveTo explore the technique experience and short- term and long-term effect of endovascular treatment on aorioiliac artery occlusive disease.MethodsClinical data of 131 patients were admitted for aorioiliac artery occlusive disease in the Department of Vascular Surgery of Beijing Chaoyang Hospital Affiliated to Capital Cedical University in recent years were analyzed.ResultsAll the 131 patients underwent surgical operation, including 5 cases of pure catheterization (CDT); 94 cases of balloon dilatation and stent implantation; 23 cases which combind CDT, balloon dilatation, and stent implantation; 3 cases of pure balloon dilatation and 6 complicated cases of hybrid surgery. The mean operative time was 90 minutes, mean hospitaliztion time was 5 days. There were 6 cases occurred complications during perioperative period, including 3 cases of hematoma, 1 case of retroperitoneal hematoma, 1 case of acute transient ischemic attacks (TIA), and 1 case of pulmonary infection. There were 113 patients were followed-up for 1–32 months, and the median time was 16 months, the follow-up rate was 86.3% (113/131). During the follow-up period, 2 patients died, 1 died of myocardial infarction and 1 died of multi-organ failure. The one-year patency rate was 89.3% (100/112). During the follow-up period, 13 patients relapsed, including 5 patients who underwent secondary stent implantation, 1 patient who underwent CDT and percutaneous transluminal angioplasty (PTA), and 7 patients who received conservative treatment due to mild symptoms.ConclusionsThe treatment of aorioiliac artery occlusive disease still needs to choose reasonable measures according to the lesions, and even several measures should be combined to simplify the lesions, lower risk and receive better effect.
ObjectiveTo analyze the therapeutic effects of open surgery and endovascular treatment for mesenteric venous thrombosis.MethodsThe clinical data of 22 patients with mesenteric venous thrombosis from March 2005 to January 2014 were analyzed retrospectively. One patient underwent open surgery including removal of necrotic small intestine and thrombectomy of superior mesenteric vein immediately admission to the hospital. Five cases were treated with simple anticoagulation and cured. Sixteen cases received thrombolytic therapy after primary anticoagulant therapy.ResultsOne case who underwent open surgery died of multiple organ failure at 72 h after the surgery. Five cases who received simple anticoagulant reached clinical relief finally. Sixteen patients who received thrombolytic therapy achieved recanalization totally or partially. Three cases died during follow-up (3 months to 7 years, average) of which 1 died of recurrence of acute superior mesenteric venous thrombosis, 1 died of myocardial infarction, and 1 died of stroke.ConclusionsFor patients with symptomatic mesenteric venous thrombosis, if there is no intestinal necrosis, there will be encouraging results by interventional thrombolytic therapy. And the treatment effect needs further experience accumulation in more cases.
Objective To explore the method of preparing the electrospinning of synthesized triblock copolymers of ε-caprolactone and L-lactide (PCLA) for the biodegradable vascular tissue engineering scaffold and to investigateits biocompatibil ity in vitro. Methods The biodegradable vascular tissue engineering scaffold was made by the electrospinning process of PCLA. A series of biocompatibil ity tests were performed. Cytotoxicity test: the L929 cells were cultured in 96-wellflat-bottomed plates with extraction media of PCLA in the experimental group and with the complete DMEM in control group, and MTT method was used to detect absorbance (A) value (570 nm) every day after culture. Acute general toxicity test: the extraction media and sal ine were injected into the mice’s abdominal cavity of experimental and control groups, respectively, and the toxicity effects on the mice were observed within 72 hours. Hemolysis test: anticoagulated blood of rabbit was added into the extracting solution, sal ine, and distilled water in 3 groups, and MTT method was used to detect A value in 3 groups. Cell attachment test: the L929 cells were seeded on the PCLA material and scanning electron microscope (SEM) observation was performed 4 hours and 3 days after culture. Subcutaneous implantation test: the PCLA material was implanted subcutaneously in rats and the histology observation was performed at 1 and 8 weeks. Results Scaffolds had the characteristics of white color, uniform texture, good elasticity, and tenacity. The SEM showed that the PCLA ultrafine fibers had a smooth surface and proper porosity; the fiber diameter was 1-5 μm and the pore diameter was in the range of 10-30 μm. MTT detection suggested that there was no significant difference in A value among 3 groups every day after culturing (P gt; 0.05). The mice in 2 groups were in good physical condition and had no respiratory depression, paralysis, convulsion, and death. The hemolysis rate was 1.18% and was lower than the normal level (5%). The SEM showed a large number of attached L929 cells were visible on the surface of the PCLA material at 4 hours after implantation and the cells grew well after 3 days. The PCLA material was infiltrated by the inflammatory cells after 1 week. The inflammatory cells reduced significantly and the fiber began abruption after 8 weeks. Conclusion The biodegradable vascular tissue engineering scaffold material made by the electrospinning process of PCLA has good microstructure without cytotoxicity and has good biocompatibil ity. It can be used as an ideal scaffold for vascular tissue engineering.
