Abstract
OBJECTIVE In uterine artery embolization (UAE) for the treatment of fibroids, nondegradable particles permanently occlude the uterine artery (UA). These particles remain in the vessels and can cause secondary undesirable effects, such as severe pain after embolization and fertility issues. In this prospective experimental study, we aimed to evaluate the angiographic recanalization, local and systemic reactions, and uterine damage occurring after performing UAE with newly developed degradable starch microspheres (DSMs) in sheep. MATERIALS AND METHODS Under general anesthesia, eight nonpregnant sheep underwent bilateral UAE using DSMs to achieve stasis. Angiographic evaluation was performed on days 1, 3 and 7 after embolization to assess in vivo recanalization. In addition, the angiographic series were scored via a modified embolization score. A postmortem tissue examination was performed to determine whether DSMs and foreign body inflammatory reactions were present and to assess uterine necrosis. RESULTS Complete bilateral embolization of the UA and cervicovaginal branches was achieved in all treated animals. Recanalization of the occluded arteries was evident in 25 of 27 arteries during the angiographic evaluation. In all sheep, there were multifocal areas of uterine necrosis, and some uterine vessels contained intraluminal material consistent with DSMs. The average weight of both uterine horns was significantly correlated with both the number of microspheres needed for complete embolization (r = 0.69, ρ<0.01) and the average percentage of necrosis in both uterine horns (r = 0.64, ρ<0.05). CONCLUSIONS Our findings demonstrated the efficacy of vascular embolization with DSM by inducing ischemic changes in the uterus and subsequent recanalization of previously occluded arteries.

Clinical Study on the Treatment of Benign Prostatic Hyperplasia by Embolization of Prostate Artery Based on Embosphere Microspheres and Gelatin Sponge Granules. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:1424021. [PMID: 35126897 PMCID: PMC8808190 DOI: 10.1155/2022/1424021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 12/28/2021] [Indexed: 11/30/2022]
Abstract
Prostatic hyperplasia can cause dysuria, such as frequent urination, urgency of urination, increased nocturia, poor urination, and other symptoms, which seriously affect the quality of life of old men. We aim to compare and analyze the safety and clinical effect of embolization of the target blood vessels of ruptured prostatic hyperplasia with gelatin sponge particles and embosphere microspheres. Methods. The transcatheter MRI was performed in 422 patients. Among them, 198 patients were treated with gelfoam particles and 224 patients were treated with embosphere microspheres. The clinical effect and adverse reactions were observed and analyzed by biochemical and imaging examination. Four hundred and twenty two cases were hemostasis. In the gelatin sponge group, 34 patients had recurrent bleeding 24–36 hours after embolization, 122 patients had different degrees of elevation of prostatic hyperplasia transaminase (31 cases increased to more than 1000 U/L), 198 patients had different degrees of elevation of bilirubin; in the microsphere group, there was no significant difference in prostatic hyperplasia function indexes between the two groups. Conclusion. Compared with the gelfoam embolic agent, the embosphere embolic microsphere has a good efficacy and safety in the treatment of prostatic hyperplasia rupture and hemorrhage, with a light adverse reaction, a low probability of recanalization, and little damage to the postoperative prostatic hyperplasia function, which is conducive to the benign recovery of perioperative patients and is worthy of clinical application.

Abstract
Purpose To compare effectiveness of three widely used embolic agents in partial splenic embolization (PSE) by analyzing their clinical, laboratory, and radiological outcomes within one year of follow-up. Materials and methods This retrospective study examined 179 patients who underwent PSE to manage hypersplenism secondary to cirrhosis. Patients were divided into 3 groups according to embolic agent used. Group 1 (gelatin sponge) included 65 patients, group 2 (embospheres) included 58 patients, and group 3 (PVA) included 56 patients. Clinical, laboratory, and radiological outcomes were compared between groups. Results The technical success rate was 100% in all groups. Pain as a major complication was lower in the gelatin sponge group (20%) compared to the embosphere group (31%) and PVA group (32.3%). Major complications other than pain were found in 20.1%; 24.6% in gelatin sponge group, 15.5% in embosphere group and 19.6% in PVA group (p = 0.045). WBCs and platelet counts showed a significant increase after PSE in all groups. Entire splenic volume as measured by computed tomography after PSE showed no significant difference among the 3 groups; however, the volume of infarcted spleen was significantly lower in the gelatin sponge group compared to other two groups (p = 0.001). The splenic span was significantly reduced one-year post-procedure in three groups (p = 0.006), and it was significantly less in embosphere and PVA groups compared to gelatin sponge group (p < 0.05). Recurrent bleeding was higher in gelatin sponge group (p < 0.05). Conclusions Permanent embolic materials achieved better laboratory and radiological outcomes than gelatin sponge particles in PSE of cirrhotic hypersplenism patients. However, permanent particles were associated with greater abdominal pain.

Abstract
BACKGROUND Uterine fibroid embolization (UFE) is an effective treatment for uterine leiomyomata. Optimizing the choice of embolic agents is imperative to achieve better patient outcomes with maximum resource utilization. PURPOSE To evaluate the efficacy and cost-effectiveness of trisacryl gelatin microspheres (TAGM) versus combined TAGM and gelatin sponge (GS) embolization in the treatment of symptomatic uterine leiomyomata. MATERIAL AND METHODS Between July 2007 and December 2010, 106 consecutive patients underwent UFE with TAGM. Between January 2011 and December 2016, 123 consecutive patients underwent UFE with a combination of TAGM/GS. The primary outcomes were successful infarction rate (≥90% infarction) of the dominant leiomyoma and percentage reduction in uterine and dominant leiomyoma volume on MRI at six months. Secondary outcomes included adverse event rates, pain scores, and change in clinical symptoms at six months. The embolic agents utilized per procedure were recorded and a cost-effectiveness analysis was performed. RESULTS Baseline characteristics of both groups were similar. Successful infarction was achieved in 93.2% of the TAGM group and 94.6% of the TAGM/GS group (P = 0.52). Reduction in uterine volume (TAGM 40.7%, TAGM/GS 44.4%, P = 0.16) and dominant leiomyoma volume (TAGM 47.6%, TAGM/GS 50.1%, P = 0.29) at six months was similar. No significant difference was observed in symptom improvement at six months (P = 0.8). The mean number of TAGM vials utilized and cost per procedure was 6.3 and $1688.40 for TAGM embolization and 3.6 and $979.50 for TAGM/GS embolization, respectively. CONCLUSION Primary and secondary outcomes were comparable when performing UFE with TAGM versus combined TAGM/GS. The combined use of TAGM/GS reduced the mean cost of embolic agents by 42%.

Abstract
Uterine Artery Embolization (UAE) is a noninvasive alternative to open surgery for treatment of uterine myomatosis. This study aims to analyze the efficacy and safety of UAE in these cases. A systematic review was carried out of studies available on the Medline (via PubMed) and the LILACS and PEDro (via the Biblioteca Virtual em Saúde) databases. The searches found 817 studies, 7 of which were selected according to the eligibility criteria (analytical, longitudinal, retrospective, or prospective studies), with a total of 367 patients studied. The variables analyzed and the characteristics of the studies included were collated and input to a database. Rates of volume reduction of the uterus and the dominant myoma were 44.1% and 56.3%, respectively. Mean rate of complete infarction of the dominant myoma was 88.6% (82-100%). The mean number of complications observed was 15±8.6 cases, most of which were classified as minor, and no deaths were recorded. The mean number of re-interventions in absolute values was 12.2±15.5 cases. Therefore, in the literature analyzed, uterine artery embolization is an effective procedure with a low rate of complications for treatment of uterine leiomyomatosis.

Abstract
Interventional radiology encompasses a wide range of procedures and the degree of associated pain depends predominantly on the procedure being undertaken. Procedures may be painful during but not after the procedure, relatively painless during but painful after the procedure, or relatively painless during and after the procedure. However, there is a lack of good quality publications in interventional radiology that specifically address the subject of peri- and postprocedural pain management. Nevertheless, a variety of more or less complex protocols exist for intraprocedural sedation and for peri- and postprocedural analgesia. While weight-based protocols for procedural sedation have demonstrable benefit, protocols for postprocedural pain relief after major procedures have not been sufficiently rigorously evaluated.
