Hepatic Hemangioma: Review of Imaging and Therapeutic Strategies.

Hepatic hemangiomas are the most common benign liver tumors. Typically, small- to medium-sized hemangiomas are asymptomatic and discovered incidentally through the widespread use of imaging techniques. Giant hemangiomas (>5 cm) have a higher risk of complications. A variety of imaging methods are used for diagnosis. Cavernous hemangioma is the most frequent type, but radiologists must be aware of other varieties. Conservative management is often adequate, but some cases necessitate targeted interventions. Although surgery was traditionally the main treatment, the evolution of minimally invasive procedures now often recommends transarterial chemoembolization as the treatment of choice.

Transarterial Bleomycin-Lipiodol Chemoembolization for the Treatment of Giant Hepatic Hemangiomas: An Assessment of Effectiveness.

This study evaluates the effectiveness of superselective transcatheter arterial chemoembolization (TACE) using a bleomycin-lipiodol emulsion in treating giant hepatic hemangiomas. A retrospective review included 31 patients with a mean age of 53 ± 10.42 years who underwent TACE from December 2014 to October 2022, with follow-up imaging examinations to assess outcomes. Technical success was defined as successful embolization of all feeding arteries, and clinical success was defined as a reduction in hemangioma volume by 50% or more on follow-up imaging. This study observed a 100% technical success rate. Post-embolization syndrome was common, and two cases of asymptomatic hepatic artery dissection were noted. Clinical success was achieved in 80.6% of patients, with significant volume reduction observed in the majority. Conclusively, superselective transcatheter arterial chemoembolization with bleomycin-lipiodol emulsions is presented as a viable and effective treatment option for giant hepatic hemangiomas. With no procedure-related mortality and significant volume reduction in most cases, this method offers a promising alternative to surgical intervention. This study's findings suggest a need for further exploration and validation in larger-scale prospective studies.

Articular Cartilage Reconstruction with Hyaluronate-Based Scaffold Significantly Decreases Pain and Improves Patient's Functioning.

Articular cartilage lesions negatively affect patients' well-being, causing severe pain and significantly limiting functioning. The purpose of this study was to evaluate the effectiveness of a one-stage reconstruction, performed arthroscopically using a hyaluronate-based scaffold. Pain reduction and functional improvement were assessed. The study also evaluated if postoperative vitamin D supplementation and rehabilitation protocol impact obtained outcomes. A group of 29 patients was included in a retrospective study. All the participants underwent arthroscopic reconstruction of osteochondral lesions using hyaluronate-based scaffolds. The study group used standard questionnaires to self-assess their condition before surgery and at the time of completion. Despite the aforementioned, all the participants fulfilled two original questionnaires on postoperative rehabilitation and vitamin D supplementation. Significant pain reduction (mean NRS 1.83 vs. 7.21, p < 0.0001) and functional improvement (mean Lysholm score 82.38 vs. 40.38, p < 0.0001; mean OKS 40.2 vs. 23.1, p < 0.0001) were found. No differences in pain reduction and functional improvement were seen between genders. The impact of post-operative rehabilitation and vitamin D supplementation on clinical outcomes was found to be statistically nonsignificant. The results obtained in this study clearly confirm the effectiveness of osteochondral reconstruction using hyaluronate-based scaffolds. The outcomes were equally favorable, regardless of postoperative rehabilitation and vitamin D supplementation.

Safety and Feasibility of Transarterial Bleomycin-Lipiodol Embolization in Patients with Giant Hepatic Hemangiomas.

Giant hepatic hemangiomas present a significant clinical challenge, and effective treatment options are warranted. This study aimed to assess the safety and feasibility of transarterial bleomycin-lipiodol embolization in patients with giant hepatic hemangiomas. A retrospective analysis was conducted on patients with giant hepatic hemangiomas (>5 cm). Transarterial chemoembolization (TACE) was performed using 7-20 cc of lipiodol mixed with 1500 IU of bleomycin. Safety outcomes, including post-embolization syndrome (PES), hepatic artery dissection, systemic complications, and access site complications, were evaluated. Radiation doses were also measured. Feasibility was assessed based on the achieved hemangioma coverage. Seventy-three patients (49 female, 24 male) with a mean age of 55.52 years were treated between December 2014 and April 2023. The average hospitalization duration was 3.82 days, and 97.3% of lesions were limited to one liver lobe. The average bleomycin dose per procedure was 1301.5625 IU, while the average lipiodol dose was 11.04 cc. The average radiation dose was 0.56 Gy. PES occurred after 45.7% of TACE procedures, with varying severity. Complications such as hepatic artery dissection (three cases), access site complications (two cases), and other complications (one case) were observed. No treatment-related mortality occurred. Hemangioma coverage exceeding 75% was achieved in 77.5% of cases. The study results suggest that transarterial bleomycin-lipiodol embolization is a safe and feasible treatment option for a heterogeneous group of patients with giant hepatic hemangiomas. This approach may hold promise in improving outcomes for patients with this challenging condition.
