[Complications and their management in intraarterial infusion chemotherapy].

Complications and its management were evaluated in intraarterial infusion chemotherapy for 188 patients with advanced carcinoma of the digestive organs from 1975 to Sept. 1991. Subjects were divided into four groups: Group I was 62 patients in whom the tip of the catheter without knots was established in the abdominal aorta via celiac axis, Group II consisted of 72 patients with the tip of the catheter without knots in the common hepatic artery. Group III had 35 patients with the tip of the catheter with knots (Anthron catheter) in the common hepatic artery. Group IV was 19 patients with the tip of the anthron catheter connected to the Infuse A-Port in the common hepatic artery. The most frequent complications seen among Group I, II and III were caused by catheter thrombosis (11.3%) in Group I, spontaneous dislodgement of catheter (26.4%) in Group II and extravasation (20%) in Group III. By using 16 gauge Toray Anthron catheter with Heparin coating on its inner and outer surfaces, the number of complications in Group I and II was kept smaller. Extravasation, on the other hand, has been less frequently seen in Group III by establishing the tip of the catheter at the branching site of the gastroduodenal artery from the common hepatic artery. Complications in Group IV (19 patients) were noted only in 3 patients, i.e., extravasation, subcutaneous necrosis and subcutaneous abscess, respectively. Therefore, we concluded that Group IV showed the most favorable intraarterial infusion chemotherapy with the most infrequent complications.
