Case: A 46-year-old man was admitted to the emergency department due to a two-day history of right lower abdominal pain. Computed tomographic angiography (CTA) demonstrated a dissecting intimal flap in both renal arteries and right renal infarction. After admission, we started medical management with anticoagulation and control of hypertension. CTA on day 9 after admission revealed a new left renal infarction, but he had no renal dysfunction or uncontrolled hypertension. Patient was treated conservatively and was discharged on day 17 after an uneventful clinical course. Although spontaneous renal artery dissection (SRAD) is a rare condition, clinicians must be mindful of the possibility of SRAD in patients with acute abdominal pain.

A 69-year-old female manager of an apparel store with a hobby of ballroom dancing presented to our hospital with increasingly fatigued legs while commuting to work or during dancing. A thorough examination revealed right iliac artery atresia, left iliac artery hypoplasia, and bilateral superficial femoral artery atresia. Thus, bilateral iliac artery/common femoral artery bypass surgery was performed, which consequently improved the patient’s symptoms. Congenital malformations of the iliofemoral artery are extremely rare. Although there are many case reports of residual sciatic artery malformations, very few cases of isolated complete absence/hypoplasia have been reported.
