Wide exposure of lesions during the subtemporal approach often leads to temporal lobe injury caused by excessive retraction. A brain retraction technique using gelatin sponge pieces was developed to minimize intraoperative brain retraction during the subtemporal approach. After aspirating cerebrospinal fluid and slackening the temporal lobe, 2-3 pieces of gelatin sponge are inserted between the...

BACKGROUND Bile duct injuries after transarterial chemoembolization (TACE) have been reported; however, the exact pathogenic mechanisms and clinical implications of the injuries remain to be clarified. STUDY A total of 950 consecutive patients with hepatocellular carcinoma (HCC) were studied. Among them, 807 were treated with TACE and the remaining 143 were treated with transarterial chemoinf...

We report the case of a 26-year-old man who presented with a non-painful priapism with a history of 3 months permanent erection after suffering a perineal trauma. An arteriocorporal fistula with a turbulent flow between the right cavernosal artery and the corpus cavernosum, conclusive for a high-flow priapism was initially detected by colour Doppler ultrasound. A superselective embolization wit...

INTRODUCTION Several biomaterials can be used in ear surgery to pack the middle ear or support the graft. The absorbable gelatin sponge is the most widely used, but it may produce fibrosis and impair ventilation of the middle ear. OBJECTIVE This experimental study aimed to investigate the inflammatory effects of the sugarcane biopolymer sponge (BP) in the rat middle ear compared with absorbab...

Marine sponges are extremely rich in natural products and are considered a promising biological resource. The major objective of this work is to couple a green extraction process with a natural origin raw material to obtain sponge origin collagen/gelatin for biomedical applications. Marine sponge collagen has unique physicochemical properties, but its application is hindered by the lack of avai...

BACKGROUND Surgical tumor resection is the main treatment for tumors however the treatment process often results in massive bleeding and tumor cell residue. The main aim of this research was to address problems such as bleeding, systemic chemotherapy side effects while enhancing quality of life, and increasing drug concentrations at the tumor site by developing a novel formulation with local lo...

BACKGROUND Spinal fusion surgery is associated with significant blood loss, which may result in potential clinical complications, it is necessary to take safe and effective measures to reduce blood loss in surgery. We perform this study to assess the impact of three different hemostatic materials on perioperative blood loss. METHODS We performed a Randomized Controlled Trial research and recr...

BACKGROUND This is a randomized controlled trial research to assess the hemostatic efficacy of gelatin sponge, collagen sponge, and topical use of tranexamic acid (TXA) on postoperative blood loss in posterior spinal fusion surgeries. METHODS We recruited patients with spinal degenerative diseases into the study from November 2013 to October 2016. All the participants were assigned to 3 group...

Gelatin sponge particles are commonly used in the conventional transarterial chemoembolization (c-TACE) as an adjuvant embolizing agent for hepatocellular carcinoma (HCC). However, there are few reports regarding the clinical applications of gelatin sponge microparticles (GSMs) as a main embolizing agent in the treatment of HCC. This retrospective study aim to evaluate the efficacy and safety o...

The reported success rate of uterine artery embolization (UAE) for obstetrical hemorrhage is more than 90%. We experienced a case of failed UAE for postpartum hemorrhage, although an embolic particle was found pathologically in the uterine vessels without coagulation. A 42-year-old woman (gravida 7, para 2) with placenta previa had genital bleeding at 35 weeks of gestation, and cesarean section...
