Emergency endovascular treatment of a superior mesenteric artery occlusion.

Endovascular treatment of acute mesenteric ischemia is rarely reported. We report a patient with a 1-year history of chronic mesenteric ischemia who presented with acute worsening of his symptoms and peritoneal signs. Aortography depicted an occlusion of the superior mesenteric artery, which was successfully managed with immediate percutaneous angioplasty (PTA) and stent placement. The patient's clinical condition improved markedly and an exploratory laparotomy performed the following day confirmed the viability of the intestine. He remains symptom-free 12 months after the procedure, and color Doppler follow-up showed that the stent is patent.

Long term survival after compound hemipelvectomy.

Three patients survived free of disease ten and one-half, ten and almost six years, respectively, following compound hemipelvectomy for a variety of tumors. Each patient had been operated upon previously at least three times, but the tumors were still well localized despite the propensity for local infiltration or growth. In addition to the lower extremity and the ipsilateral pelvic bones, varieties of organs were resected. In one patient with chondrosarcoma of the pelvis, there was a local recurrent mass and, in another with adenocarcinoma of the appendix, a solitary pulmonary metastasis. Both of these lesions were successfully resected, and the patients remained free of disease nine and four and one-half years, respectively, after resection of the recurrent lesions. The third patients had carcinoma of the penis with metastases in both groins; carcinoma of the breast devedeveloped nine and one-half years after hemipelvectomy. The two younger patients were fitted with prostheses, and all three adjusted fairly well physically and psychologically to their disability. Frequently, the huge size of these tumors, the infiltration of many contiguous structures and, possibly, other features known to be associated with a bad prognosis make them appear to be incurable. We suggest that slowly growing tumor which remain localized for a long time can be controlled if adequately excised, possibly because they may be associated with strong systemic immunity. The extremely few such patients who may be encountered in surgical practice ought, therefore, to be recognized as potentially curable and treated accordingly, despite the often formidable risk or technical problems at operation and the resultant postoperative disabilities.
