Cateteres venosos totalmente implantáveis em pacientes com neoplasia hematológica e não hematológica

BACKGROUND: We analyse whether hematological tumors increase the risk of complications of totally implantable catheters and if there are differences regarding procedure time when it is perfomed through venous dissection or venous puncture. METHODS: We studied 68 patients with neoplasia in Hospital Santa Rita from Porto Alegre, between February 1998 and December 1999, who had required central venous access for chemotherapy. Forty-eight patients were female and the mean age was 55.6 years. Thirty-one patients had hematological tumors. RESULTS: Postoperative complications were observed in 13 patients (7% with device obstruction, 6% with hematoma and 6% with infection), but there was no difference regarding the pattern of the neoplasia (p = 0.56). Venous dissection and venous puncture were performed in 30 and 38 patients, respectively, with no difference concerning surgical time (p = 0.42). CONCLUSIONS: Hematological tumors did not increase the risk of complications of totally implantable catheters; furthermore, both surgical techniques (venous dissection or venous puncture) are acceptable choices, with similar surgical times, since one respects minimal platelet count of 50 000/mL and careful hemostasis techniques and compressive dressings.
