[PMID: 34089077 DOI: 10.1007/s00270-021-02883-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 05/24/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE The aim of this study was to compare the safety and efficacy of transhepatic puncture tract embolization with n-butyl cyanoacrylate (n-BCA) versus coils after percutaneous transhepatic portal vein interventions in patients with hepatocellular carcinoma (HCC). It was also the aim of the study to evaluate the extent of artifacts in CT exams during FU. METHODS Single-center retrospective study from 2017-2019 in 190 patients who underwent percutaneous transhepatic portal vein interventions. The transhepatic puncture tracts were embolized with n-BCA in 88 patients (Group A) and with coils in 102 patients (Group B). Procedure-related complications and image noise around coils and n-BCA were compared between the groups. No significant differences were noted at baseline between both groups (platelets, coagulation, liver disease, types of procedures, liver function, liver tumors). RESULTS All patients underwent transhepatic puncture tract embolization. Procedure-related complications were only observed in patients from Group B: subcapsular hemorrhage (n = 2; 1.96%), hepatic artery hemorrhage (n = 1; 0.98%), and pseudoaneurysms combined with hemobilia occurred (n = 1; 0.98%). In Group A, the distal part of the punctured portal vein branch was embolized with n-BCA in 1 patient (1.14%). Four major complications in Group B Vs 0 in Group A were observed, respectively (p < 0.0001). The image noise around n-BCA was significantly lower than that around coils (10.7 ± 1.7 HU vs. 54.3 ± 15.0 HU, p < .001). CONCLUSIONS n-BCA tract embolization is more effective than using coils, with fewer bleeding events, at the cost of a higher potential for unintended embolization of portal vein branches.

Clinical application of partial splenic embolization. ScientificWorldJournal 2014; 2014:961345. [PMID: 25538966 PMCID: PMC4235844 DOI: 10.1155/2014/961345] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2014] [Revised: 09/20/2014] [Accepted: 09/29/2014] [Indexed: 02/05/2023] Open
Abstract
Partial splenic embolization (PSE) is one of the intra-arterial therapeutic approaches of diseases. With the development of interventional radiology, the applications of PSE in clinical practice are greatly extended, while various materials are developed for embolization use. Common indications of PSE include hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia, autoimmune hemolytic anemia, splenic trauma, idiopathic thrombocytopenic purpura, splenic hemangioma, and liver cancer. It is also performed to exclude splenic artery aneurysms from the parent vessel lumen and prevent aneurysm rupture, to treat splenic artery steal syndrome and improve liver perfusion in liver transplant recipients, and to administer targeted treatment to areas of neoplastic disease in the splenic parenchyma. Indicators of the therapeutic effect evaluation of PSE comprise blood routine test, changes in hemodynamics and in splenic volume. Major complications of PSE include the pulmonary complications, severe infection, damages of renal and liver function, and portal vein thrombosis. The limitations of PSE exist mainly in the difficulties in selecting the arteries to embolize and in evaluating the embolized volume.

Abstract
OBJECTIVE To evaluate the safety and feasibility of N-butyl cyanoacrylate (N-BCA) embolization of percutaneous transhepatic portal venous access tract and to establish an appropriate technique. METHODS 40 consecutive patients underwent percutaneous transhepatic portal venous intervention for various reasons. Embolization of percutaneous transhepatic portal venous access tract was performed after the procedure in all of the patients using N-BCA and Lipiodol® (Lipiodol Ultra Fluide; Laboratoire Guerbet, Aulnay-sous-Bois, France) mixture. Immediate ultrasonography and fluoroscopy were performed to evaluate perihepatic haematoma formation and unintended embolization of more than one segmental portal vein. Follow-up CT was performed, and haemoglobin and haematocrit levels were checked to evaluate the presence of bleeding. RESULTS Immediate haemostasis was achieved in all of the patients, without development of perihepatic haematoma or unintended embolization of more than one segmental portal vein. Complete embolization of percutaneous access tract was confirmed in 39 out of 40 patients by CT. Seven patients showed decreased haemoglobin and haematocrit levels. Other complications included mild pain at the site of embolization and mild fever, which resolved after conservative management. 16 patients died during the follow-up period owing to progression of the underlying disease. CONCLUSION Embolization of percutaneous transhepatic portal vein access tract with N-BCA is feasible and technically safe. With the appropriate technique, N-BCA can be safely used as an alternate embolic material since it is easy to use and inexpensive compared with other embolic materials. ADVANCES IN KNOWLEDGE This is the first study to investigate the efficacy of N-BCA for percutaneous transhepatic portal venous access tract embolization.

Abstract
Post-renal biopsy bleeding refractory to angioembolization usually requires graft nephrectomy as a life-saving measure. Gelatin-thrombin hemostatic matrix injection in the needle tract is a novel attempt to control bleeding in such cases and to salvage the allograft. We hereby describe two cases of post-graft biopsy bleed. Both these patients continued to bleed even after angioembolization. They were shifted to the operating room upon developing hypotension, having received multiple blood transfusions with the intention of performing graft nephrectomy to save their lives. However, bleeding was successfully controlled by using Gelatin-thrombin hemostatic matrix injection in the biopsy needle tract. Patients improved hemodynamically after the procedure. Graft function returned to normal in both the cases. At an average follow-up of 10.4 months, both the patients have shown stable graft functions.

Abstract
Surgical treatments have usually been preferred for early posttransplantation portal inflow abnormalities. However, these treatments are limited due to their technical difficulty and multiple complicating factors. The present study reports the efficacy and safety of percutaneous transhepatic primary stent placement to treat early posttransplantation (<or=1 month) portal vein (PV) stenosis. A total of 9 patients who had undergone living donor liver transplantation underwent percutaneous stent placement to treat PV stenosis. The average interval between liver transplantation and stent placement was 13 +/- 10 days. Technical and clinical success was obtained in 7 (77.8%) of the 9 patients. Of the 7 patients with clinical success, 1 died of cerebral hemorrhage within 1 month following stent placement. The remaining 6 patients have remained healthy and without recurrence of PV stenosis until the time this manuscript was completed, and follow-up Doppler ultrasound (US) or computed tomography (CT) obtained 66.6 +/- 16.1 months after stent placement revealed patent portal inflow in all of these 6 patients. Major complications occurred in 3 patients, i.e., 2 cases of hemoperitoneum caused by blood oozing from a transhepatic tract of the liver grafts and 1 case of intrahepatic pseudoaneurysm. These complications were successfully treated using surgical ligation (n = 2) or transarterial coil embolization (n = 1). In conclusion, although we did experience some procedural complications, the percutaneous transhepatic primary stent placements in our study showed acceptable technical and clinical results for treating early posttransplantation PV stenosis. In addition, long-term PV patency following stent placement was excellent. However, additional experience and further studies will be needed to verify the usefulness of primary stent placement in the early posttransplantation period.

Abstract
OBJECTIVE The purpose of our study was to compare radiofrequency cauterization, embolization using an absorbable gelatin sponge, and a Histoacryl-Lipiodol mixture plugging as postbiopsy bleeding reduction methods after splenic core needle biopsy in a dog model. MATERIALS AND METHODS Eleven mongrel dogs were randomly separated into nonheparinized (n = 5) and heparinized (n = 6) groups. Eight splenic biopsies per animal were performed using an 18-gauge automated core biopsy needle: two as controls, two ablated by radiofrequency, two embolized using an absorbable gelatin sponge, and two plugged using a Histoacryl-Lipiodol mixture. Procedure times and postbiopsy bleeding amounts were assessed. Statistically significant differences were determined by repeated measures analysis of variance; the Tukey-Kramer test for multiple comparisons was used for post hoc comparisons. Three-day follow-up CT scans were obtained to check for procedure-related complications or delayed bleeding. RESULTS The postbiopsy bleeding reduction groups showed significantly less blood loss than the control group for both the nonheparinized (p < 0.0001) and heparinized groups (p < 0.0001). In the heparinized group, both radiofrequency cauterization (p < 0.01) and gelatin sponge embolization (p < 0.05) significantly reduced bleeding compared with Histoacryl-Lipiodol mixture plugging. Gelatin sponge embolization was the longest procedure (p < 0.001). On follow-up CT, no delayed bleeding was observed. However, multiple Histoacryl-Lipiodol emboli were observed in the splenic and portal veins in all the dogs we treated. CONCLUSION Radiofrequency cauterization was found to be the most useful postbiopsy bleeding reduction method in terms of the amount of bleeding and the procedure time.
