Abstract
BackgroundArterial tumor embolism (ATE) is a rare but life-threating complication.Presentation of caseA 55-year-old man with acute lower-limb ischemia was referred to our hospital after endovascular intervention failed and underwent above-the-knee amputation for severe limb necrosis. On postoperative day 8, he developed small bowel necrosis and underwent resection. Histopathological examination of the resected bowel revealed that the submucosal arterial emboli were positive for the markers of squamous cells. He had unresectable lung squamous cell carcinoma with left atrium invasion. The subsequent embolisms were thought to be caused by the advanced lung cancer.ConclusionATE is rare but should be considered as a differential diagnosis for unidentified arterial occlusion.

We report a case of ATE that spontaneously occurred after chemoradiotherapy of primary lung cancer
Case presentation A 55-year-old man presented to a local hospital, complaining of acute severe pain in his right lower leg. He was diagnosed with acute lower limb arterial embolism and underwent endovascular intervention: percutaneous aspiration of thrombus and balloon angioplasty of right distal superficial femoral artery (SFA) (Fig. 1a)
Summary
Arterial tumor embolism (ATE) is a rare but life-threating complication. Presentation of case: A 55-year-old man with acute lower-limb ischemia was referred to our hospital after endovascular intervention failed and underwent above-the-knee amputation for severe limb necrosis. We report a case of ATE that spontaneously occurred after chemoradiotherapy of primary lung cancer. The embolus eroded through the wall of a pulmonary vein and embolized through fragmentation with resultant showering of tumor emboli to multiple arterial sites. * Correspondence: togo@koto.kpu-m.ac.jp; this_is_105@yahoo.co.jp 1Department of Surgery, Matsuyama Red Cross Hospital, 1, Bunkyo-cho, Matsuyama-shi, Ehime 790-8524, Japan Full list of author information is available at the end of the article heparinisation was started.
