Emergency embolization for the treatment of acute hemorrhage from intercostal arteries.
Emerg Radiol

Show Abstract
Hide Abstract
To evaluate embolotherapy for the emergency management of acute bleeding from intercostal arteries. Between October 2003 and August 2012, 19 consecutive patients with hemorrhage from intercostal arteries were scheduled for emergency embolization. The primary study endpoints were technical and clinical success, which were defined as angiographic cessation of bleeding, and cessation of clinical signs of hemorrhage. The secondary study endpoints were periprocedural complications and 30-day mortality rate. In most patients (74 %), hemorrhage was caused by iatrogenic procedures with subsequent intercostal artery laceration. One of the patients was treated twice for recurrent hemothorax caused by a new intercostal artery pseudoaneurysm 7.5 years after the initial procedure. Thus, 20 procedures were performed in these 19 patients. Overall technical success was 85 %. In six patients, no embolization of the "backdoor" was feasible, and in two of these patients additional embolization of other intercostal arteries was necessary to prevent hemorrhage via collateral vessels. Clinical signs of hemorrhage ceased after embolotherapy in 16 of 20 procedures (clinical success 80 %). The mean follow-up was 358.7?±?637.1 days. One minor procedure-related complication occurred. The 30-day mortality rate was 21 %, however, this was unrelated to intercostal artery hemorrhage. Embolotherapy is an effective emergency therapy for patients with acute hemorrhage from intercostal arteries. Especially if embolization of the backdoor is not feasible, collateral supply via other intercostal arteries should be either ruled out or embolized to prevent ongoing hemorrhage. Despite successful embolotherapy, a majority of patients underwent surgery during follow-up to remove the symptomatic hematoma.

Specific CT 3D rendering of the treatment zone after Irreversible Electroporation (IRE) in a pig liver model: the "Chebyshev Center Concept" to define the maximum treatable tumor size.
BMC Med Imaging
PUBLISHED: 01-10-2014
Show Abstract
Hide Abstract
Size and shape of the treatment zone after Irreversible electroporation (IRE) can be difficult to depict due to the use of multiple applicators with complex spatial configuration. Exact geometrical definition of the treatment zone, however, is mandatory for acute treatment control since incomplete tumor coverage results in limited oncological outcome. In this study, the "Chebyshev Center Concept" was introduced for CT 3d rendering to assess size and position of the maximum treatable tumor at a specific safety margin.

Experimental liver embolization with four different spherical embolic materials: impact on inflammatory tissue and foreign body reaction.

Show Abstract
Hide Abstract
We sought to describe and compare material specific inflammatory and foreign body reactions after porcine liver embolization with spherical embolic agents. In 40 animals, superselective liver embolization was performed with four different spherical embolic agents of various sizes: 40-120 microm (Embozene, Embosphere), and 100-300 microm, 500-700 microm, and 700-900 microm (Embozene, Embosphere, Bead Block, and Contour SE, respectively). After 4 or 12 weeks, inflammatory reactions were evaluated microscopically according to the Banff 97 classification. For investigation of foreign body reactions, a newly designed giant cell score was applied. Banff 97 and giant cell scores closely correlated. At 4 weeks, small Embosphere particles (100-300 microm) had a significantly higher Banff 97 score than Embozene, Bead Block, and Contour SE of the corresponding size. After 12 weeks, the calculated differences were not statistically significant. Comparison between the 4-week results and the 12-week results revealed a statistically higher Banff 97 score for Embosphere 100-300 microm after 4 weeks than after 12 weeks (P = 0.02). The overall foreign body reaction was pronounced after embolization with smaller particles, especially in small Embosphere particles. Giant cell numbers with Embosphere 100-300 microm were statistically higher compared with the other materials of corresponding size (P < 0.0001). Inflammatory and giant cell reactions after embolization procedures depend on the embolic material. The overall inflammatory reaction was low. However, marked inflammation was associated with small Embosphere particles at 4 weeks, a finding that might be caused by the allogeneic overcoat. Correspondingly, giant cells indicating a foreign body reaction were more frequently associated with small particle sizes, especially after embolization with small Embosphere particles.

Hide Abstract
We report a case of an uncommon giant pseudoaneurysm of the gastroduodenal artery secondary to chronic pancreatitis. It presented with a perfused volume of 17.3 cm(3) close to the branch-off of the right hepatic artery. Superselective transcatheter embolization including interlocking detachable coils and a mixture of Ethibloc and Lipiodol was our technique of choice. Following the procedure, the patient was in hemodynamically stable condition. At that time, he was free of any clinical symptoms and showed no further signs of bleeding or ischaemia. Additionally, we present an overview of the relevant literature.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
