Pulmonary sequestration is a congenital malformation characterized by dysplastic pulmonary tissue which receives blood supply by arterial systemic system, not in communication with tracheobronchial tree. Although it could be asymptomatic, it can also cause recurrent infections and hemoptysis, rarely massive and fatal. The conventional treatment consists in surgical resection of the pulmonary se...

interventional techniques aim to find safer and better ways to treat vascular diseases even in many instances, the interventional radiology solutions has been considered the only treatment option for the patients. interventional radiologists are specialists who perform minimally invasive procedures instead of surgery or other treatments. these procedures apply various imaging and catheterizatio...

Understanding the intra-tumoral distribution of chemotherapeutic drugs is extremely important in predicting therapeutic outcome. Tissue mimicking gel phantoms are useful for studying drug vitro but quantifying laborious due to need section over relevant time course and individually quantify elution. In this study we compare a bespoke version traditional phantom sectioning approach, with novel c...

Gelfoam and polyvinyl alcohol foam particles each have advantages and disadvantages for therapeutic embolization. It was theorized and confirmed that a mixture of the two retains the advantages and eliminates the disadvantages of each. Two mixtures were prepared, tested in animals, and used successfully in 14 patients. It was found that the mixtures of Gelfoam and polyvinyl alcohol foam particl...

Background: To evaluate the results (rates of success, complications and clinical outcomes), advantages or disadvantages of Uterine Artery Embolization (UAE). Materials and Methods: We were able to follow 28 women with uterine fibroids, ranging age of 21 to 48 years (mean age 34 y), who underwent UAE in Mostafa Khomeini Hospital from May 2005 to June 2014, for the period of 6 months to 8 years....

Purpose: Transcatheter hepatic artery embolization therapy is a minimally invasive alternative for treating inoperable liver cancer but recurrence is frequent. Multifunctional agents, however, offer an opportunity for tumor eradication. In this study, we were aim to synthesized poly (lactic-co-glycolic acid) (PLGA) microspheres encapsulating hollow CuS nanoparticles (HCuSNPs) and paclitaxel (PT...

BACKGROUND AND PURPOSE We tested the hypothesis that treatment of embolic stroke with recombinant human tissue plasminogen activator (rhtPA) alters cerebral expression of adhesion molecules. METHODS Male Wistar rats were subjected to middle cerebral artery occlusion by a single fibrin-rich clot. P-selectin, E-selectin, and intercellular adhesion molecule-1 (ICAM-1) immunoreactivity was measur...

Objectives: Five percent of patients with recurrent gastrointestinal (GI) hemorrhage have indeterminate origin by radiological and endoscopic examinations. To improve diagnostic accuracy therapeutic embolization, the technique provocative mesenteric angiography (PMA) has been developed. It involves addition pharmacologic agents to standard angiographic protocols induce bleeding. Material Method...

We report a case of carcinosarcoma of the minor salivary glands of the left palatine tonsil, an especially rare location. Imaging characteristics assessed at CT, MR imaging, and angiography are presented. In addition, we describe our experience with preoperative therapeutic endovascular embolization of this hypervascular tumor.
