RESUMO
A case of pulmonary artery perforation by the placement of a balloon-tipped, flow-directed (Swan-Ganz) catheter, as demonstrated postmortem by angiography and confirmed by conventional autopsy method, is reported. Angiography is an effective adjunctive modality in the postmortem diagnosis and localization of pulmonary artery perforation. In cases of suspected catheter-induced pulmonary artery perforation and death, postmortem angiography may prove useful to the forensic pathologist.

Eighty-two percutaneous enterostomies were performed at three institutions with the Cope suture anchor for stomach or jejunal wall stabilization during alimentation tube placement. The anchors were successfully placed into the stomach or jejunum in 81 cases. Early in the series, two anchors were misplaced, with no sequelae. There were no other complications at the time of placement. In all successful cases, excellent immobilization of the viscus was achieved. Tract dilation and tube placement were easily performed, and there were no guidewire or tube dislodgments.

Ureteral perfusion studies in patients without preexisting renal access currently must be intermittently interrupted for intrarenal pressure measurement. A double-lumen needle has been successfully placed in four patients (two with native and two with transplanted kidneys). This permits simultaneous perfusion and intrarenal pressure monitoring yet maintains the safety and ease of use of a single skinny needle.

Six commercially available movable core guide wires were compared with each other and with a new design in glass models simulating tortuous vessels. The results demonstrate a wide variability in performance of the commercially available wires and the superiority of the new design.
