Linehan, v., dobson, j.L., dalton, a., hache, n., gullipalli, r.(2022).Successful prophylactic embolization of a renal artery aneurysm during pregnancy.Annals of vascular surgery, 79, 437.E1-437.E5.Https://doi.Org/10.1016/j.Avsg.2021.07.030.Medtronic review of the literature article found a 39-year-old female underwent a procedure for the treatment of an 1.4cm unruptured left renal artery aneurysm (raa) during second trimester of pregnancy after presenting in the emergency department with upper right quadrant pain at 9 weeks gestation.The procedure was delayed to the second trimester for fetal safety.For the procedure, a rebar 0.018" microcatheter was advanced over the guidewire through the guide catheter and positioned distally in the upper pole branch.A 5 x 30mm solitaire ab (sab) was then deployed across the aneurysm neck for stent-assisted coiling of the aneurysm.The same microcatheter was advanced on the guidewire through the sab stent struts to access the lower pole branch and raa.4 axium micro coils and 4 additional coils were successfully delivered and implanted to achieve aneurysm embolization.No device malfunctions were reported in the article information.At the end of the procedure some thrombus was visualized within the sab stent.The patient was immediately given 162mg of acetylsalicyclic acid.After consultation with hematology and high risk obstetrics, the patient was also given 300mg of clopidogrel.Additionally gentle angioplasty was performed with a 4mm balloon across the thrombus within the stent repeat contrast injection showed good flow across the stent in the dominant artery supplying the left kidney.The patient had uneventful recovery and was discharged the following day on dual antiplatelet therapy (dapt) for 6 weeks to be stopped at least 1 month before the planned delivery date.6 week follow-up doppler ultrasound (us) showed well preserved renal cortex and good perfusion in the left kidney.The patient delivered a healthy baby at term via planned c-section.At 3 months post-partum, the patient had a follow-up enhanced abdominal ct which showed embolization of the aneurysm and patent renal artery with good perfusion of the left kidney.The patient was noted to have no adverse event in the 3 years of follow-up after the intervention.
