Treatment of malignant inferior vena cava obstruction with Gianturco-Rosch-Z stents: a single center 13-year experience.

Rationale And Objectives: Malignant obstruction of the IVC can cause severe morbidity and impairment of quality of life in end-stage oncology patients. However, medical literature regarding minimally-invasive palliation using large diameter percutaneous stents, particularly the Gianturco-Rosch-Z (GRZ) stent is limited.

Materials & Methods: A retrospective review from January 2004 to February 2017, revealed 17 subjects with malignant obstruction of the IVC who were treated with a total of 34 GRZ stents.

Lymphatic interventions for isolated, iatrogenic chylous ascites: A multi-institution experience.

Objectives: Lymphangiography and thoracic duct embolization are established treatments for post-surgical chylothorax. There is only limited experience in their application to treat post-surgical chylous ascites. A multi-center analysis of the technical and clinical success of lymphangiography and lymphatic interventions in the treatment of isolated, iatrogenic chylous ascites is reported.

The thoracic duct: clinical importance, anatomic variation, imaging, and embolization.

Unlabelled: The thoracic duct is the body's largest lymphatic conduit, draining upwards of 75 % of lymphatic fluid and extending from the cisterna chyli to the left jugulovenous angle. While a typical course has been described, it is estimated that it is present in only 40-60% of patients, often complicating already challenging interventional procedures. The lengthy course predisposes the thoracic duct to injury from a variety of iatrogenic disruptions, as well as spontaneous benign and malignant lymphatic obstructions and idiopathic causes.

Thoracic duct embolization and disruption for treatment of chylous effusions: experience with 105 patients.

Purpose: To review the indications, technical approach, and clinical outcomes of thoracic duct embolization (TDE) and thoracic duct disruption (TDD) in patients with symptomatic chylous effusions.

Materials And Methods: A total of 105 patients who underwent 120 consecutive TDE/TDD procedures were retrospectively reviewed. Data including cause of effusion, procedural technique, and pre- and postprocedural effusion volume were analyzed.

Leiomyosarcoma of the popliteal vein.

Primary vascular leiomyosarcomas are rare tumors arising from the media of vessel walls, involving the extremities in about one third of reported cases, and the popliteal vein even less frequently. We report a case of popliteal vein leiomyosarcoma in a 62-year old man who presented with leg pain and edema 4 weeks following spine surgery. Findings on ultrasound, MRI and CT angiography are reviewed, with particular emphasis on the value of CT angiography in fully evaluating the extent of the mass and in assisting percutaneous biopsy.
