To evaluate the risk of rupture of a 77 mm thrombosed popliteal artery aneurysm (PAA) in an 82-year-old woman, the aneurysm was percutaneously punctured and the intrathrombotic pressure (ITP) was measured preoperatively. The percentage of the mean ITP to the mean brachial artery pressure was 80%. The aneurysm was judged to have the risk of rupture, and replacement with a prosthetic graft was performed. The percentages of the mean ITP to the mean radial artery pressure and to the mean femoral artery pressure measured intraoperatively were 83% and 71%, respectively, which approximated to the percentage measured preoperatively. PAA may have the risk of rupture even though thrombosed, and preoperative measurement of the ITP might be useful to decide surgical indication.
