| Acute hemoptysis (massive haemoptysis) caused by Various lung lesions is the medical emergency endanger the patient life, for without surgical indications of big haemoptysis, pure medical treatment is often difficult to work, patients often choked to death caused by blood clots blocking the airway, immediately stop bleeding is the key to successful rescue Bronchial artery embolization (Bronchial artery embolization) is directly injected into the bleeding blood vessels through the catheter embolization material, to seal filling of bleeding blood vessels, immediately stop bleeding rate is high, the hemostatic effect is exact, has become a more commonly used treatment method, common embolism materials such as gelatin sponge (gelfoam, GS) and (polyvinyl alcohol, ivalon, PVA) particles are widely used in various causes such as hemoptysis caused by arterial embolization.Objective:1. The comparison respectively using polyvinyl alcohol (PVA) and gelatin sponge (GS) particles line of bronchial artery embolization in acute big haemoptysis recent rate of target vessel, discusses two kinds of embolic materials in BAE the merits of the recent curative effect for the treatment of hemoptysis.2. By observing the gelatin sponge (GS) particles and polyvinyl alcohol (PVA) particles in the liquid immersion under the inflation situation, discuss the removal of pituitrin shrink blood vessels such as drugs, blood vessel diameter recover, in target distribution in endovascular embolization materials.Methods:1. Clinical data record: group A selection in our hospital between December2011and March2014,40cases of patients with acute large haemoptysis, ahead of selective bronchial artery catheterization, clear indications of bronchial artery embolization, through the catheter into the polyvinyl alcohol (PVA) particles embolization distal vessels, then to the spring coil embolization trunk group B:group B to collect the outer court,39cases of acute large hemoptysis patients with gelatin sponge (GS) distal embolization vessels, the trunk again with spring coil embolism Two groups of patients were performed after admission pituitrin or Bai Mei hemostatic drug therapy, such as observation and follow-up recent recurrence after embolization, recurrent hemoptysis patients with bronchial arteriography examination again, observe whether there is the original target vessels, and look for any leakage switch blood vessels, again with the same thrombosis embolism agent Statistical analysis carried out in accordance with the embolization material grouping antitheses.2. Laboratory data record: gelatin sponge (GS) from each particle and polyvinyl alcohol (PVA) particles several bubble into the water, and then observed under microscope measuring scale, corresponding to every time radiography, compare the expansion of the two kinds of embolic materials in the water changes Results: A group of40patients with successful embolization in7cases of17.5%(7/40) in the near future again hair haemoptysis, the original target recanalization embolism accounted for4cases (10%),3cases of leakage switch again hair group B in39patients with embolization in1case (3%) patients with15months BAE5times,4times again hair haemoptysis were found A original embolism target recanalization, separated by A recent target blood vessels to the differences in rate of63A, B two groups have statistical significance (P<0.01) in two kinds of embolic materials rapidly expand, rainwater to soak for A minute as A starting point, the longest for nine hours after observation, gelatin sponge (GS) particles slightly expanded, polyvinyl alcohol (PVA) particles was nearly unchanged.Conclusion:1. The bronchial artery embolization big haemoptysis, using gelatin sponge particles in the near future curative effect is better than that of PVA particles. |
