Mechanical thrombolysis for the treatment of thrombosed hemodialysis access grafts.

abstract：:In his overview of the history and theoretical developments of radiotherapy, the author stresses the following concepts: (a) sensitivity is not linked to histology but to the volume of cancer; (b) the dose must not necessarily be homogeneous in the target volume but related to varying volumes of cancer; (c) the fact t...
