Partial splenic embolization with Glubran®2/Lipiodol® mixture for oncological patients with hypersplenism-related thrombocytopenia requiring systemic chemotherapy

Selective Arterial Embolization of Ruptured Hepatocellular Carcinoma with N-Butyl Cyanoacrylate and Lipiodol: Safety, Efficacy, and Short-Term Outcomes

The rupture of hepatocellular carcinoma (rHCC) is uncommon but causes sudden life-threatening bleeding. Selective transarterial embolization (STAE) is an effective bleeding-control option. The optimal embolic agent is unknown, and data on the use of cyanoacrylate glue are lacking. The objective of this study was to report the outcomes of cyanoacrylate-lipiodol embolization for rHCC. We retrospectively reviewed the files of the 16 patients (14 males; mean age, 72 years) who underwent emergency cyanoacrylate-lipiodol STAE at a single center in 2012-2023 for spontaneous rHCC. All 16 patients had subcapsular HCC and abundant hemoperitoneum. The technical success rate was 94% (15/16). Day 30 mortality was 19%; the three patients who died had severe hemodynamic instability at admission; one death was due to rebleeding. Liver enzyme levels returned to baseline by day 30. No rebleeding was recorded during the median follow-up of 454 days in the 10 patients who were alive with available data after day 30. Larger prospective studies with the collection of longer-term outcomes are needed to assess our results supporting the safety and effectiveness of cyanoacrylate-lipiodol STAE for rHCC. Randomized trials comparing this mixture to other embolic agents should be performed.

Simultaneous CSM‐TACE with CalliSpheres® and partial splenic embolization using 8spheres® for hepatocellular carcinoma with hypersplenism: Early prospective multicenter clinical outcome

Background

Primary hepatocellular carcinoma is often complicated with hepatitis and liver cirrhosis. Some patients develop different degrees of splenomegaly, hypersplenism and hypohepatia due to the aggravation of liver cirrhosis, which to some extent interfere with the treatment of tumors and even affect the prognosis of patients. In this study, we prospectively evaluate the efficacy and safety of simultaneous CalliSpheres® microspheres transcatheter arterial chemoembolization (CSM-TACE) and partial splenic embolization (PSE) using 8spheres® for hepatocellular carcinoma (HCC) with hypersplenism.

Methods

Ninety consecutive HCC patients with hypersplenism who underwent CSM-TACE were selected: 32 patients in CSM-TACE+PSE group, and 58 patients in CSM-TACE group. The peripheral blood cell counts (leukocyte, platelet (PLT), liver function and red blood cell (RBC)), CSM-TACE and/or PSE related complications, and the tumor control rate at 1 month after CSM-TACE were compared. The survival time and prognostic factors were also observed.

Results

Before CSM-TACE, there were no significant differences in sex, age, Child-Pugh grade, tumor size, and alpha-fetoprotein (AFP) between the two groups. After CSM-TACE, the PLT and white blood cell (WBC) counts in CSM-TACE+PSE group were significantly higher than those in the CSM-TACE group (P<0.05). There were no significant differences in RBC before and after treatment (P > 0.05). In the CSM-TACE group, there were no significant differences in WBC, PLT, and RBC before and after treatment (P > 0.05). There was no significant difference in liver function at 1 month after treatment between the two groups. The cholinesterase (CHE) level in the CSM-TACE+PSE group after CSM-TACE+PSE was obviously higher than that before CSM-TACE+PSE and higher than that in the CSM-TACE group (P<0.05). However, the level of CHE returned to the preoperative level 1 month after CSM-TACE in the CSM-TACE group. The objective response rate (ORR) and median overall survival (OS) in the CSM-TACE+PSE group were higher than those in the CSM-TACE group (P<0.05). The adverse reactions of the two groups were fever, abdominal pain, stomach discomfort, nausea, and vomiting, and no serious complications occurred. The degree of abdominal pain and fever in the experimental group was lower than that in the control group (P > 0.05).

Conclusions

Simultaneous CSM-TACE and PSE using domestic embolization particles for HCC with hypersplenism have good safety and efficacy and has a low incidence of PSE-related adverse events, it is conducive to improving liver function reserve, and can further improve the median OS.

Splenic artery embolization with N-butyl cyanoacrylate in patients with blunt abdominal trauma

Introduction

Splenic artery embolization (SAE) has been shown to be safe and effective for non-operative management of patients with splenic trauma while preserving splenic function. A variety of coils, plugs, particles and liquid embolics have all been used. NBCA (n-butyl cyanoacrylate) is used less frequently than other modalities but is effective.

Methods

A retrospective review of all patients who underwent SAE with NBCA for blunt abdominal trauma at a single tertiary medical center over a six-year period.

Results

Out of 123 SAE patients, 7 utilized NBCA; 6 patients had intraparenchymal splenic artery pseudoaneurysms, 2 had intraparenchymal arteriovenous fistulas, and 5 had active extravasation from the spleen on CT imaging. There was 100% technical success rate. There were no acute post-op complications or complications at 30-day and 90-day follow up. One patient died 2 days following SAE secondary to worsening subdural hematoma unrelated to SAE.

Conclusions

NBCA is safe and effective in treating patients with splenic injury particularly in patients with high grade splenic injury demonstrating extensive intraparenchymal vascular injury and/or intraprocedural extravasation in distal locations.
