Manufacturer Narrative

A1 - patient identifier: clinical study id (b)(4).A2 - age at time of event: the subject was 79 years old at the time of study enrollment.

Event Description

Hi-peitho clinical study it was reported that the subject experienced moderate bleeding and hematoma as a result of the index procedure.On (b)(6)2023, the subject underwent treatment with study device using ultrasound guidance.Two ekos catheters were successfully placed in both the right lower lobar artery and the left lower lobar artery.Therapy was initiated via the ekos devices at a rate of 2 mg/hr for a total dose of 1 mg across both catheters on same day.On (b)(6)2023, the subject initiated treatment of enoxaparin 8000 iu once a day via subcutaneous route.On the same day, the subject was noted with bleeding from introducer sheath site during administration of tissue plasminogen activator (tpa) and ultrasound.In response, unfractionated heparin was stopped, and subject was adjusted onto therapeutic dose of enoxaparin.The severity of event was considered to be moderate.Tpa and ultrasound were stopped at 20:35 and the catheter was removed.Compression of injection site and size of hematoma was documented.On 03-jul-2023, the outcome of the event was considered resolved.
