The patient was a 61-year-old woman diagnosed with a pulmonary artery aneurysm with a maximum diameter of 66 mm and progressive pulmonary valve regurgitation, and surgery was decided upon. Pulmonary artery replacement and pulmonary valve replacement were performed. Pulmonary artery aneurysms are extremely rare, and there are no clear treatment guidelines, including surgical indications, so each case must be carefully considered. At the same time, because they are rare, it is difficult to master the surgical technique, and various innovations are considered necessary.

We experienced two cases of anterior tibial varicose veins caused by intraosseous venous drainage anomaly. Case 1 was a 62-year-old man who had a localized protrusion on the anterior surface of the left tibia for 10 years, which began to cause pain one month ago. CT revealed dilated veins penetrating the left tibia, and symptoms improved after surgical treatment. Case 2 was a 74-year-old woman who developed pain in the right lower leg two weeks ago. Colour doppler echography showed refluxing blood flow from a cortical bone defect, and CT confirmed veins penetrating the tibia. Surgical treatment also improved her symptoms. Anterior tibial varicose veins caused by bone perforators due to intraosseous venous drainage anomaly are relatively rare.
