Description of event according to initial reporter: on (b)(6) 2015: a male patient was diagnosed as suffering from dvt and thus, the complaint filter was placed in the ivc.From that day on, systemic administration of urokinase 240000 unit/day and heparin 800 unit/hour from right brachial vein was started.On (b)(6) 2015: although mild edema had been already observed on the patient by this day, the condition of the edema worsened further.Therefore, the medication of the systemic administration was changed to urokinase 120000 unit/day and heparin 1400 unit/hour and wait-and-see approach was taken.On (b)(6) 2015: as edema did not improve, cta was conducted, through which blood clots around the filter and in the pulmonary artery were confirmed.Thus, proper amount of t-pa for a man weighing 85kg and heparin 1600 unit were infused so as to dissolve the blood clots.On (b)(6) 2015: since filter retrieval was planned to be performed on this day, angiography from the left femoral artery was conducted, through which total occlusion of the ivc below the filter was confirmed.Although urokinase 60000 unit was infused through an infusion catheter (fountain catheter), the condition did not improve.Therefore, filter retrieval was cancelled and the filter remained placed in the ivc as-it-was.The physician determined to monitor the patient while leaving the infusion catheter in the body and administrating urokinase 60000 continuously through it.He plans to perform filter retrieval in the future, but when to perform has not been determined yet.Additional information received (b)(6) 2015: on (b)(6) 2015: since the fountain catheter almost slipped out of the body, a cv (central venous) catheter was placed alternatively.In addition, as the physician thought the blood clots would not be dissolved enough only with one directional infusion, another cv catheter was also placed from right femoral vein.On (b)(6) 2015: since the condition of the edema in lower limb was getting better, angiography was performed, which confirmed that the blood clots had decreased to a large extent.And therefore, filter retrieval was determined to be performed on that day.After another manufacturer's filter (new house protect /toray medical) was placed by left jugular approach, the complaint filter was retrieved from right jugular vein successfully.Although there still remains a few blood clots in ivc, the physician supposes that these clots will be dissolved without problems because the blood flow of the patient's has been already improved.Patient outcome: despite severe edema, there is no threat to his life.
