“…There are currently no established treatment strategies in terms of duration of treatment for idiopathic renal infarction [ 3 ]. Table 2 depicts the reports obtained by searching for “idiopathic renal infarction” in PubMed [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Nine cases were published between 1995 and 2021.…”

Background: Renal infarction is an extremely rare disease. Although more than 95% of cases are symptomatic, there have been no previously reported asymptomatic cases, without any abnormal blood and urine test findings. Furthermore, the efficacy of long-term treatment of idiopathic renal infarction remains unknown. Case Presentation: A 63-year-old Japanese male underwent laparoscopy; a very low anterior resection of the rectum for lower rectal cancer (stage II) four years and five months prior to diagnosis with renal infarction. During the follow-up imaging studies, asymptomatic idiopathic renal infarction was found incidentally. The blood and urine test findings were normal. Contrast-enhanced computed tomography revealed a linearly bordered area of poor contrast in the dorsal region of the right kidney; however, no renal artery lesions, thromboembolic disease, or coagulation abnormalities were observed. Initial treatment with rivaroxaban 15 mg/day resulted in the remission of the infarcted lesion. The anticoagulation therapy was terminated after about 18 months without any incidences of re-infarction or bleeding events. Conclusions: We reported a very rare case of asymptomatic idiopathic renal infarction where blood and urine tests revealed no abnormal findings, and it was diagnosed incidentally during a post-treatment follow-up examination for lower rectal cancer. Long-term anticoagulant therapy for idiopathic renal infarction should be terminated at an appropriate time, taking the risk of bleeding into account.

Renal artery thrombosis is a rare condition that requires early diagnosis and urgent intervention to prevent renal infarction and permanent renal damage. Possibility of renal artery thrombosis should be considered in patients with underlying hypercoagulable state presented with acute unremitting flank pain, nausea and vomiting. We report a case of a 35-year-old man with underlying nephrotic syndrome who presented with three days history of acute non-localized and non-resolving abdominal pain and vomiting. He was initially referred to general surgery for acute intestinal obstruction. Contrast-enhanced computed tomography (CECT) abdomen revealed acute left renal infarction secondary to total thrombotic occlusion of the left renal artery. The patient was treated with endovascular manual aspiration thrombectomy resulting in partial revascularization of left renal artery with restoration of renal function, complete resolution of symptom and good clinical outcomes. This case report serves as a reminder for physicians to include renal infarction in the differential diagnosis when evaluating a patient with acute abdomen, particularly in patient with hypercoagulable state. This case also aligns with other experiences demonstrating positive outcomes after endovascular thrombectomy, even in the presence of prolonged renal ischemia time of more than 72 hours.
