Long-term retrieval of modified Günther Tulip vena cava Filters: an animal study.

We modified the Günther Tulip Filter to allow long-term retrieval and tested this modified filter design in an animal experiment. Fourteen modified Günther Tulip Filters (Celect filter) were inserted percutaneously into the inferior venae cavae of 7 domestic adult sheep (2 filters per animal). Before removal, 3 months after filter placement, cavography was performed and the filters were removed.

New optional IVC filter for percutaneous retrieval--in vitro evaluation of embolus capturing efficiency.

Purpose: In-vitro evaluation of a new caval filter (Cook Celect Filter) developed for delayed percutaneous retrieval in comparison to the Gunther Tulip filter.

Materials And Methods: The new Celect filter is constructed on the basis of the Tulip filter and consists of 4 primary anchoring legs and additional 8 thinner secondary wires to stabilize the filter and to guarantee adequate filtering efficiency. The filtering wires are of the same amount and equal distribution as the filtering wires of the Tulip filter.

[Transarterial embolization of the kidney: review of the literature].

The percutaneous transarterial total embolization of the kidney is a minimal invasive therapeutic procedure for radiological nephrectomy. The reported indications, technique, results and complications of percutaneous transarterial total renal embolization are reviewed. Aside from transient symptoms as part of the postembolization syndrome with a stated incidence of 47 % to 100 % of embolizations, other complications are relatively rare and occur in the range of 0 % to 20 % with a mortality of up to 3.

[Percutaneous embolization of the kidney: indications and clinical results].

Objective: Renal embolisation offers a minimal invasive means of renal ablation under primary palliative indication. We evaluated our experience with this technique in a series of 40 patients.

Patients And Methods: From 1996 to 2002 a total of 40 patients underwent total embolisation of the kidney.

[MR-guided coil embolisation of renal arteries in an animal model].

Purpose: To test the feasibility of MR-guided coil embolization with passive visualization in an animal model.

Materials And Methods: All experiments were performed on a 1.5 T interventional MR-scanner (Gyroscan ACS-NT, Philips, Netherlands).
