New nonsurgical technique for multiple pericardial biopsies.
We report a new, nonsurgical technique for obtaining multiple pericardial biopsies in patients with pericardial effusion. A short catheter is introduced by the Seldinger technique under fluoroscopy through the subxiphoid approach. The pericardial fluid is aspirated and the catheter replaced by an 8F teflon sheath with a curved tip. A bioptome is inserted through the sheath, and air is allowed to enter the pericardium. This method outlines the parietal percardium. The curved sheath directs the bioptome to the left or right wall. Eighteen consecutive patients had an average of eight pieces of pericardium removed. On histological examination, three patients had malignancy. Six had tuberculous granuloma, and mycobacterium tuberculosis was cultured from all six tissue specimens but only once from the fluid. Tissue smears showed acid fast bacilli in four out of six, whereas the fluid was negative in all. The biopsy yielded diagnostic information in nine out of ten patients with a thickened pericardium. There were no complications.
