Abdominal aortic aneurysm with horseshoe kidney

Brief introduction of abdominal aortic aneurysm combined with horseshoe kidney Horseshoe kidney is the most common type of congenital malformation in the kidney. The incidence rate in the normal population is 1:400 to 1:1000, and the ratio of male to female is 2:1. The two kidneys are usually fused together at the fourth lumbar vertebrae in the anterior midline of the aorta. The collecting system and the ureter are displaced forward and inward, and the ureter passes in front of the fused isthmus. In addition, atypical renal artery blood supply is often present. basic knowledge The proportion of sickness: 0.004% - 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: chronic nephritis kidney stones

Etiology of abdominal aortic aneurysm combined with horseshoe kidney

Causes

Caused by abnormal development of the embryo.

Prevention of abdominal aortic aneurysm combined with horseshoe kidney

The cause of this disease is due to malformation of the embryo, so it cannot be directly prevented. Therefore, early detection, early diagnosis and early treatment are of great significance for indirect prevention of this disease. Regular examination should be done during pregnancy. B-ultrasound can detect abnormalities early. If the child has a tendency to develop abnormalities, chromosome screening should be done in time. After the confirmation, artificial abortion should be performed in time to avoid the birth of the diseased children.

Complications of abdominal aortic aneurysm combined with horseshoe kidney Complications chronic nephritis kidney stones

Chronic nephritis, urinary tract infection, kidney stones.

Symptoms of abdominal aortic aneurysm combined with horseshoe kidney Common symptoms Low back pain, abdominal pain, vascular murmur, abdominal tenderness, systolic murmur, dorsal artery pulsation disappeared

Most patients with horseshoe kidney have no obvious symptoms, and about one-third of patients have urinary tract complications: such as chronic nephritis, urinary tract infection, kidney stones, etc. When combined with abdominal aortic aneurysm, both manifestations can occur.

Horseshoe kidney patients often have no obvious symptoms, and occasionally found in the examination, the significance of preoperative diagnosis is to reduce the side damage and improve the success rate of surgery.

Examination of abdominal aortic aneurysm combined with horseshoe kidney

1. Abdominal B-ultrasound: Abdominal aortic aneurysm and the kidney located in front of it can be found near the midline and the upper pole is far from the midline, and the isthmus of the inferior pole is hypoechoic.

2. CT examination: visible in the abdomen aortic aneurysm in front of the deformed kidney, and can understand the local aortic aneurysm.

3. Intravenous pyelography: visible renal pelvis, renal pelvis, the long axis of the ureter is "inverted eight" shape, and often due to ureteral distortion or abnormal vascular compression of hydronephrosis.

4. Aortic-renal angiography: not only can understand the extent of abdominal aortic aneurysm, organ involvement, it is important to understand the abnormal supply of arteries in horseshoe kidney, is an essential examination.

Diagnosis and differentiation of abdominal aortic aneurysm with horseshoe kidney

Should be identified with chronic nephritis, urinary tract infections, kidney stones.
