A Case Report of Successful Surgical Treatment of High Aortic Occlusion with Acute Ischemia of Intrapelvic Organs and Bilateral Lower Extremities / 日本心臓血管外科学会雑誌

This is a case report of a 57-year-old woman with high aortic occlusion (HAO) who had acute symptoms of severe ischemia of the lower extremities and the intrapelvic organs. Generally, HAO is a chronic ischemic disease of the lower extremities and the intrapelvic organs; therefore, acute HAO is relatively rare. Acute thrombotic occlusion of a major collateral artery might be the cause of acute HAO. Laser Doppler flowmetry of the sigmoid colon was useful to evaluate the ischemia of intrapelvic organs. Thrombectomy of the juxtarenal portion with the suprarenal aortic cross clamp was performed within four minutes, then the clamp was moved to the infrarenal portion. The remaining occluded aorta was replaced with a Y-shaped knitted Dacron graft. She had no symptoms after the surgery except renovascular hypertension. Seventy five percent stenosis of the right renal artery was exacerbated to 99%. Vascular clamping of the right renal artery might have been the cause of severe stenosis. Percutaneous transluminal renal angioplasty was successfully performed after the surgery. Aggressive renal artery reconstruction during surgery is recommended in cases with moderate or severe renal artery stenosis.

A Successful Result of One Stage Operation for Atrial Septal Defect and Funnel Chest / 日本心臓血管外科学会雑誌

A 6-year-old boy underwent one stage operation for atrial septal defect (ASD) and funnel chest. The procedure began with removal of cost-sterno complex (plastron) following median skin incision. Plastron was kept in cold saline with antibiotics during ASD closure, and sterno-costal elevation method was performed. Simultaneous operation for heart disease and funnel chest is profitable in preventing postoperative circulatory or respiratory complications, in avoiding problems of two stage operation such as adhesion and mental stress of the patients. In addition, wide exposure and easy approach to the heart is available with this one stage procedure. Although current refinement both of cardiac and thoracic surgery has encouraged the possibility of simultaneous corrections for heart disease and funnel chest, much precautions against bleeding and infection are necessary for the satisfactory surgical result.
