ObjectiveTo review the research progress of the clinical application of the medial sural artery perforator flap (MSAPF).MethodsThe relevant domestic and abroad literature on the clinical application of MSAPF was extensively consulted, and the research progress were summarized and analyzed in aspect of its definition, anatomical characteristics, clinical application, surgical resection and improvement, and advantages and disadvantages of flaps, etc.ResultsMSAPF has the advantages of relatively constant anatomical position, thin flap texture, long vascular pedicle, large vessel diameter, no sacrifice of main blood vessels, concealed donor site, no hair, and fewer complications; it can carry nerves, tendons, and muscles to construct chimeric flaps to repair three-dimensional wounds; and can also repair wounds with high aesthetic and functional requirements such as hand, foot and ankle, head and neck, etc.ConclusionThe MSAPF is a versatile, various forms, functional diversification, and three-dimensional flap donor site with various application forms and ideal repair effectiveness.
ObjectiveTo compare vein valve function following pharmacomechanical thrombolysis (PMT) with simple catheter-directed thrombolysis (CDT) for deep vein thrombosis.MethodsWe retrospectively analyzed the clinical data of sixty patients who suffered acute lower extremity deep vein thrombsis in our hospital between October 2016 and March 2017. All patients underwent contralateral preprocedural duplex and bilateral postprocedure duplex to access patency and valve function. The patients were divided into three groups including a group A with catheter-directed thrombolysis (CDT) alone (36 patients with 20 males and 16 females at average age of 56 years), a group B with PMT alone (15 patients with 8 males and 7 females at average age of 55 years), and a group C with PMT combined CDT (9 patients with 4 males and 5 females at average age of 56 years). The valve function was compared among the Group A, Group B and Group C.ResultsThere were 40.0% (24/60) patients with bilateral femoral vein valve reflux, 40.0% (24/60) patients with unilateral femoral vein valve reflux (all in the treated limbs), 20% (12/60) patients had no reflux in both limbs. Of the limbs treated with CDT alone, PMT alone and PMT combined CDT, the rate of valve reflux was 38.9% (14/36), 33.3% (5/15), and 55.6% (5/9) respectively (P=0.077).ConclusionIn the patients suffering acute DVT, PMT or PMT combined CDT does not hamper valve function compared with CDT alone.
