Male breast carcinoma presents in an advanced stage with less favorable survival, despite low histologic grade, high estrogen receptor content, and small size. Anatomic factors may have been responsible for the poor survival outcome (i.e., paucity of breast tissue and close tumor proximity to skin and nipple, facilitating dermal lymphatic spread and early regional and distant metastasis).

Local intraluminal delivery of heparin at the time of balloon angioplasty with heparin-coated hydrogel balloons results in intramural deposition of drug that persists for at least 48 hours. This in vivo technique significantly decreases platelet deposition and early smooth muscle cell proliferation after angioplasty injury.
