This 70-year-old male patient is a victim of colon cancer with liver metastases. He received a subcutaneous Port-A catheter implantation in the left subclavian vein for long-term chemotherapy. About one month after successful use, he complained of numbness sensation for hours after chemotherapy, but he would get better the following morning. Nuclear medicine scintigraphy by injecting radiopharmaceutical directly into the reservoir of Port-A catheter clearly demonstrated leakage from the sidewall of catheter. After removal of Port-A catheter, his clinical manifestations disappeared, and he tolerated subsequent chemotherapy well through peripheral intravenous administration. Conclusively, this procedure is not only easy to be performed, but an effective method to evaluate Port-A catheter function in vivo.

這名70歲的男性是結腸癌肝轉移的患者。他接受左鎖骨下靜脈皮下人工血管導管植入，進行長期化療。在成功使用約一個月後，他抱怨化療後數小時有麻木感，但第二天早上即好轉。核醫檢查的評估，通過直接注射放射性藥物到人工血管導管的貯水座（reservoir），清楚地證明了導管側壁的滲漏。移除人工血管後，其臨床表現消失，並且通過周邊靜脈給藥可以很好地耐受往後的化療。總結而言，該核醫檢查可以體內（in vivo）有效地進行人工血管功能之評估。
