متن کاملFunctionless retained pacing leads in the cardiovascular system. A complication of pacemaker treatment.

Two patients developed thrombosis and occlusion of the superior vena cava, which was relieved by the development of a collateral venous circulation. In one patient the broken tip of the lead migrated to a pulmonary artery but did ...
متن کاملLymphoid Neogenesis and Tertiary Lymphoid Organs in Transplanted Organs
The progressive organization of immune effectors into functional ectopic lymphoid structures, named tertiary lymphoid organs (TLO), has been observed in many conditions in which target antigens fail to be eliminated by the immune system. Not surprisingly, TLO have been recurrently identified in chronically rejected allografts. Although significant progress has been made over the last decades in...
