Fracture and atypical migration of an implantable central venous access device.

Distal embolization of a fractured indwelling central catheter is a rare complication. The pinch-off syndrome (POS) should be known, prevented and early detected. We present a case in which further radiological exams were required to find the fragmented catheter with an atypical migration, requiring local surgery for removing.

Current role of transcatheter arterial embolization for bladder and prostate hemorrhage.

Intractable hematuria from the bladder or the prostate can be life-threatening and its management remains a difficult clinical problem. Severe bleeding can arise as a result of radiation cystitis, bladder carcinoma, cyclophosphamide-induced cystitis, severe infection, transurethral resection of the prostate and prostate cancer. When irrigation of the bladder through a three-way catheter and fulguration of the bleeding lesions fail to stop the hematuria, a life-threatening situation can develop, when blood transfusion fails to keep pace with the rate of blood loss.

Transjugular intrahepatic portosystemic shunt for the management of acute variceal hemorrhage.

Acute variceal hemorrhage, a life-threatening condition that requires a multidisciplinary approach for effective therapy, is defined as visible bleeding from an esophageal or gastric varix at the time of endoscopy, the presence of large esophageal varices with recent stigmata of bleeding, or fresh blood visible in the stomach with no other source of bleeding identified. Transfusion of blood products, pharmacological treatments and early endoscopic therapy are often effective; however, if primary hemostasis cannot be obtained or if uncontrollable early rebleeding occurs, transjugular intrahepatic portosystemic shunt (TIPS) is recommended as rescue treatment. The TIPS represents a major advance in the treatment of complications of portal hypertension.

C-arm dual-phase cone-beam CT: a revolutionary real-time imaging modality to assess drug-eluting beads TACE success in liver cancer patients.

The advent of cone-beam computed tomography (CBCT) in the angiography suite has been revolutionary in interventional radiology. CBCT offers 3 dimensions (3D) diagnostic imaging in the interventional suite and can enhance minimally-invasive therapy beyond the limitations of 2D angiography alone. The role of CBCT has been recognized in transcatheter arterial chemoembolization (TACE) treatment of liver cancer especially with the recent introduction of dual-phase CBCT (DP-CBCT) for unresectable hepatocellular carcinoma (HCC) treatment.

Transcatheter embolization as the new reference standard for endoscopically unmanageable upper gastrointestinal bleeding.

Acute nonvariceal upper gastrointestinal bleeding (UGIB) is a major medical emergency problem associated with significant morbidity and mortality. Endoscopy is considered the first method of choice to detect and treat UGIB. Endoscopic therapy usually achieves primary hemostasis, but 10%-30% of these patients have repeat bleeding.

Lipiodol trans-arterial chemoembolization of hepatocellular carcinoma with idarubicin: first experience.

Background: There is still no consensus about the best chemotherapeutic agent for transarterial chemoembolization (TACE). A recent in vitro study demonstrated that idarubicin, an anthracycline, was by far the most cytotoxic drug on human hepatocellular carcinoma (HCC) cell lines. Idarubicin is much more lipophilic than doxorubicin, leading to higher cell penetration through lipidic membranes and greater accumulation of the drug in the lipiodol.

Transthoracic adrenal biopsy procedure using artificial carbon dioxide pneumothorax as outpatient procedure.

Many routes have been described for percutaneous adrenal gland biopsy. They require either a complex non-axial path or a long hydrodissection or even pass through an organ thereby increasing complications. We describe here an approach using an artificially-induced carbon dioxide (CO2) pneumothorax, performed as an outpatient procedure in a 57-year-old woman.
