Embolization of percutaneous transhepatic portal venous access tract with<i>N</i>-butyl cyanoacrylate

Background Liver biopsy is a widely used, safe diagnostic tool utilised by clinicians for the histopathological assessment of the liver. Our study aims to report our experience in patients who underwent ultrasound-guided plugged percutaneous liver biopsy in a tertiary care hospital in India. Material and methods The Institutional Ethical Review Board approved this retrospective study, and informed consent was obtained from all the patients. A total of 830 liver biopsies were performed between January 2014 and December 2018, of which 782 were plugged percutaneous liver biopsies. The tract was plugged using Gelfoam slurry. Various observations related to the procedures were recorded. Results Seven hundred and eighty-two were plugged percutaneous liver biopsies, which were performed during the study period. Of the 782 patients, 163 were male, and 619 were female (20.8 % and 79.2 %, respectively), with a mean age of 49.6 ± 2 years (1 month to 86 years). A 100% technical success rate was seen. No immediate major complications were documented in any of the patients who underwent plugged biopsies. No significant complications were seen in any patient. Conclusions Percutaneous liver biopsy is an extensively performed diagnostic tool. We found that ultrasound-guided percutaneous plugged liver biopsy is an easy to perform procedure, which is associated with a lower risk of a bleeding complications.

“…The use of NBCA has previously been described for tract embolization following various transhepatic procedures. Park et al have described the use of NBCA for tract embolization after portal vein intervention and have demonstrated its safety and effectiveness in sealing the tracts (30). We utilized real-time fluoroscopy to make sure that the polymerized cast was evenly distributed along the whole length of the needle tract and that it did not leak into unwanted structures.…”

Background Percutaneous biopsy is a widely-accepted technique for acquiring histologic samples of the liver. When there is concern for bleeding, plugged percutaneous biopsy (PPB) may be performed, which involves embolization of the biopsy tract. Purpose To evaluate the efficacy and safety of PPB of the liver in patients suspected to have graft rejection after living-donor liver transplantation (LDLT). Material and Methods During January 2007 and December 2013, 51 patients who underwent PPB of the liver under the suspicion of post-LDLT graft rejection were retrospectively analyzed. A total of 73 biopsies were performed. Biopsy was performed with a 17-gauge core needle and 18-gauge cutting needle. The needle tract was embolized using gelatin sponge (n = 44) or N-butyl cyanoacrylate (NBCA) (n = 29). The specimens were reviewed to determine their adequacy for histologic diagnosis. We reviewed all medical records after PPB. Results Specimens were successfully acquired in all procedures (100%). They were adequate for diagnosis in 70 cases (95.9%) and inadequate in three (1.3%). Average of 9.8 complete portal tracts was counted per specimen. One minor complication (1.4%) occurred where the patient had transient fever after the procedure. Conclusion PPB is easy and safe to perform in LDLT recipients and provides high diagnostic yield.

“…The bleeding site is usually along the tract of the guiding catheter. In their published studies, some clinicians recommend embolization of the puncture tract when retrieving the catheter ( 8 ). When there is massive bleeding, transarterial embolization can be the most effective treatment.…”

Portal vein embolization (PVE) is known as an effective and safe preoperative procedure that increases the future liver remnant (FLR) in patients with insufficient FLR. However, some possible major complications can lead to non-resectability or delayed elective surgery that results in increased morbidity and mortality. Although the majority of these complications are rare, knowledge of the radiologic findings of post-procedural complications facilitate an accurate diagnosis and ensure prompt management. We accordingly reviewed the CT findings of the complications of PVE.
