A case report of sarcoma recurrence treated with a balloon-occluded combined approach (b-MWA + b-TAE).

Sarcomas present challenges in management due to their aggressive nature. Interventional radiology, utilizing ablation and embolization, offer promising alternatives for recurrent cases. In recent years, combined techniques (ablation + embolization) and the use of balloon-microcatheter have been introduced to enhance the necrotic effect in HCC treatment. This paper presents the case of a 47-year-old female with recurrent abdominal sarcoma treated with balloon-occluded microwave ablation (b-MWA) and balloon-occluded transarterial embolization (b-TAE). Post-treatment imaging revealed a significant reduction in lesion size and absence of pathological contrast enhancement. This study highlights the potential of balloon-catheter-assisted combined therapies (b-MWA + b-TAE) in managing sarcomas, expanding the applicability of interventional radiology for inoperable cases that are too large for ablative therapy alone or requiring multiple antennas. Further research is warranted to refine protocols and enhance patient outcomes in sarcoma management.

Pancreatic Ducts Obliteration With Controlled Injection of Onyx®: A Proposal of New Onyx® Pancreatic Ducts Obliteration Scoring System.

BACKGROUND: The aim of this study was confirm the efficacy and feasibility of Onyx injection for pancreatic stump management after pancreaticoduodenectomy (PD) and investigate a new Onyx® Pancreatic Ducts Obliteration (OPDO) scoring system of pancreatic duct obliteration (PDOb) in patients with high risk of Post-Operative Pancreatic Fistula (POPF). STUDY DESIGN: We enrolled ten patients undergoing PDOb with Onyx® intraoperative controlled injection after elective PD. RESULTS: PDOb with Onyx® controlled injection was classified according to the OPDO scoring system in three degrees: complete 5/10 (50%), medium 2/10 (20%) and bad 3/10 (30%). Increased amylase in abdominal drainage was identified in two patients (20%) with a degree II and III, and resolved spontaneously within a week. A "clinically relevant" POPF (CR-POPF) was observed in one patient (10%) with a degree III and none in the patients with degree I and II. DISCUSSION: We confirm that intraoperative injection of Onyx® is a valid solution in high-risk POPF patients and our OPDO scoring system allows obtain an intraoperative classification of the degree of PDO to prevent the CR-POPOF; furthermore, it may be suggested that the viscosity of the injected product (Onyx®) reduce parenchymal fibrosis.

Intravascular leiomyomatosis with intracardiac extension: a toraco-abdominal approach.

Intravenous leiomyomatosis is a rare nonmalignant tumor, which originates from the uterine smooth muscle cells and is usually confined to the pelvic venous system. Sometimes it can extend from the pelvis through the veins into the right side of the heart; this condition is named intracardiac leiomyomatosis (ICLM). To date few cases of these conditions have been described, the treatment is surgical, often challenging and usually multidisciplinary. In this paper are described the clinical presentation, the full radiologic study and surgical treatment of a case of ICLM that authors treated at their institution with thoraco-abdominal approach. Surgical removal of the ICLM is strongly recommended, because no recurrence has been reported, in our case at 7 years we did not observe recurrence of the disease.

A Pictorial Review of the Role of Imaging in the Detection, Management, Histopathological Correlations, and Complications of COVID-19 Pneumonia.

Imaging plays an important role in the detection of coronavirus (COVID-19) pneumonia in both managing the disease and evaluating the complications. Imaging with chest computed tomography (CT) can also have a potential predictive and prognostic role in COVID-19 patient outcomes. The aim of this pictorial review is to describe the role of imaging with chest X-ray (CXR), lung ultrasound (LUS), and CT in the diagnosis and management of COVID-19 pneumonia, the current indications, the scores proposed for each modality, the advantages/limitations of each modality and their role in detecting complications, and the histopathological correlations.

How to prevent the postoperative pancreatic fistula with an ethylene vinyl alcohol copolymer (Onyx®): A proposal of a new technique.

BACKGROUNDS/AIMS: Despite the advances in identifying risk factors, improving operative technique, and postoperative patient care, pancreatic leakage after pancreatic resection remains a highly debated topic. The aim of this study is to describe our technique and our initial experience with the intraoperative embolization of the main pancreatic duct with an Ethylene Vinyl Alcohol Copolymer (Onyx®). METHODS: Two patients of 63 and 64 years underwent pancreaticoduodenectomy for a cholangiocarcinoma of the extrahepatic bile duct and a pancreatic adenocarcinoma, respectively. At the time of pancreatic parenchyma resection, a Wirsung duct was identified and catheterized. A wirsungography was done and then, embolization with Onyx® was carried out under fluoroscopic control. RESULTS: Neither of the patients developed a postoperative pancreatic fistula. They were discharged to home on the 17th and 18th postoperative day, respectively. At the last follow-up, no recurrence was found. The two patients became diabetics; both needed the support of supplementary pancreatic enzymes. CONCLUSIONS: To our knowledge, we are the first to describe this technique, which seems safe and reliable. Studies on this subject with more patients are needed to confirm the validity of this procedure.

[Gross Hematuria after kidney biopsy. A case report]. / Ematuria macroscopica dopo una biopsia renale. Caso clinico.

We describe the clinical case of a patient experiencing severe gross hematuria causing clotting in the renal pelvis, after undergoing a kidney biopsy.The ecocolordopper and CT angiography performed did not reveal the cause of hematuria.The kidney arteriography allowed the diagnosis, revealing an arteriovenous fistula responsible for bleeding together with a small false aneurysm in the lower pole of the biopsied kidney. Both lesions were successfully treated with superselective embolization with microcoils. We discuss about the diagnostic and therapeutic approach of these rare post-biopsy complications briefly focusing on the technical aspects and on possible risks that the transcatheter embolotherapy may result.

Coccygeal movement: assessment with dynamic MRI.

PURPOSE: Chronic coccygodynia is a difficult problem diagnostically and therapeutically. Moreover, there is no deep knowledge especially in the field of imaging of chronic coccygodynia. In this study several possible measurements are proposed, which all are able to demonstrate coccygeal movement during defecation, in order to assess coccygeal mobility using dynamic MRI during maximum contraction and during straining-evacuation. MATERIALS AND METHODS: A dynamic MRI study of the pelvic floor was performed in 112 patients. Five methods of measurement were assessed. Coccygeal movements were determined through the evaluation of three angles pair and two different distances measured during the phase of maximum contraction and during the phase of straining-evacuation. Results were compared according to age, sex, parity and experience of minor trauma. No patient included in the study had coccygodynia. Measurements taken by two radiologist were compared to determine interobserver agreement. RESULTS: The maximum measurement values of the two distances are homogeneous, between 9 and 9.4mm. The maximum measurement values of the three angles showed a difference that is between 21 degrees and 38 degrees . Two of three angles showed a major measurement values in the funtional texts. In only one patient the coccyx was not mobile. CONCLUSION: Our dynamic MRI study indicates that the coccyx is mobile during defecation and that it is possible to demonstrate coccygeal excursions by assessing the difference between its positions at maximum contraction and during straining-evacuation. The measurement methods used in this study for evaluating coccygeal movements resulted in variably sized observed differences, but all yielded statistically significant results in demonstrating coccygeal excursion. Among the five measurement methods, two resulted in the largest differences. Our data indicate no correlation between coccygeal movements and age, sex, parity, minor trauma and coccygodynia.
