説明
Patients with mixed connective tissue disease (MCTD) have higher rates of pulmonary arterial hypertension (PAH) than the general population. PAH is a risk for perioperative respiratory and heart failure, and marked edema of colonic stoma after sigmoidectomy. We report a case of sigmoidectomy for sigmoid colon cancer in a patient with PAH associated with MCTD for whom perioperative treatment was planned to control pulmonary arterial pressure (PAP), and a surgical strategy to avoid complications attributable to PAH and MCTD was employed.A 52-year-old woman with sigmoid cancer and severe PAH associated with MCTD underwent surgery. We controlled PAH by using intravenous epoprostenol. We selected open surgery without laparoscopy and Hartmann's operation. After surgery, severe perioperative complications were not detected, and the patient discharged from hospital 17 days after the operation.During surgery under general anesthesia, the mortality rate of PAH is high because of heart and respiratory failure. We planned to switch the PAH treatment from an oral agent to intravenous epoprostenol only in the preoperative period, and selected open surgery. We ligated the inferior mesenteric artery (IMA) and inferior mesenteric vein (IMV) below the branch of LCA to avoid marked edema of stoma. Consequently, we could avoid severe intraoperative and postoperative complications.Controlling PAP using epoprostenol, open surgery, stoma and the ligation level for the IMA and IMV preventing are important to avoid perioperative complications of sigmoid colon cancer complicated by severe PAH.
