RESUMO
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.

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.

Purpose: To assess the efficacy and safety of a low-dose, computed tomography (CT)-guided transthoracic biopsy of lung and pleural lesions. Material and methods: A total of 135 low-dose, CT-guided transthoracic lung and pleural lesions biopsies were performed. A cutting needle was utilized in 124 cases, and fine needle aspiration biopsy was performed in 14 cases. In all cases, 14- to 22-gauge biopsy needles were used. Results: Diagnostic material was obtained in 111 (82.2%) patients. In 97 (71.8%) cases neoplastic lesions were found, predominantly adenocarcinoma and non-small cell carcinoma. In 14 (12.6%) cases non atypical cells were reported. Biopsy failed to obtain material suitable for histopathological examination in 24 (17.7%) cases. Complications occurred in 31 patients, including pneumothorax in 28 patients and haematoma in 3 cases. Conclusions: Based on the obtained results, it can be stated that low-dose, CT-guided transthoracic biopsy of lung and pleural tissues is an accurate and safe procedure. Also, it is linked to a low risk of complications such as a small pneumothorax.
RESUMO
PURPOSE: Large and wide-necked bifurcation aneurysms remain technically challenging to treat by the endovascular approach. Several endovascular strategies have been established in recent years for treating wide-necked bifurcation aneurysms, such as balloon-assisted coiling, stent-assisted coiling, waffle cone technique (WCT), and intrasaccular flow disruptors. CASE REPORT: A 64-year-old woman was diagnosed with three intracranial aneurysms of the right and left middle cerebral artery and right internal carotid artery. She was qualified for endovascular treatment of the left middle cerebral artery (LMCA) aneurysm because it posed the greatest risk of rupture. Due to complicated morphology, a pCONus stent and coils were chosen for treatment. Three months later the right middle cerebral artery aneurysm was embolised and the woman was scheduled for second-stage treatment of the LMCA aneurysm. One week before the planned admission the woman was diagnosed with subarachnoid haemorrhage (SAH) in the region of the previously treated LMCA aneurysm, and the second-stage treatment was conducted with a good result. The woman was discharged in improved condition. Three months later the woman was once again admitted with SAH - an enlarged LMCA aneurysm was observed and immediate third-stage embolisation was performed, but due to complications of SAH the woman eventually died. CONCLUSIONS: On the basis of the presented case we would like to emphasise the importance of sufficient initial coil packing and frequent control of neck region of the aneurysm for the long-term stability and safety after pCONus-assisted coiling of intracranial aneurysms.
RESUMO
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.
RESUMO
Professor Czeslaw Nizankowski was an academic teacher and researcher at several universities; head of the Department of Anatomy at Wroclaw Medical University (1966-1982); and head of the Department of Biological Sciences at the Wroclaw School of Physical Education (since 1972 University School of Physical Education in Wroclaw), as well as the chancellor there. He contributed greatly to the development of morphological sciences, supervising many doctoral and post-doctoral works. He dedicated considerable time to the preparation of anatomical specimens of lungs, hearts and organs of the gastrointestinal tract. At the Museum of Anatomy, there are over 100 specimens of lungs prepared using the forced air technique improved by Professor Nizankowski, along with specimens of the bronchial tree and vascular system prepared using a corrosive technique. Professor Nizankowski was an active member of scientific societies in Wroclaw and in other cities in Poland. For his accomplishments, he received a number of ministerial and state awards, including the Knight's Cross of the Order of Polonia Restituta, and was granted an honorary doctorate by Wroclaw Medical University.
