A RARE CASE OF CELIAC AXIS ANEURYSM

Abstract number: 108

• 74 year old maleComplaints of Passing dark colored stools – 5 days

• Endoscopy showed1 ) Oesophageal venous bleb2) Antral erosion

1 ) History of slip and fall, 5 months back, fracture right neck of femur – underwent right hemiarthroplasty

2) 10 months back he was operated for left inguinal hernia (hernioplasty)• Not a known case of Tuberculosis, diabetes mellitus, hypertension, bronchial asthma.

• On physical examination patient was found to have 1) Kyphosis and scoliosis 2) Small umbilical hernia

• Fusiform aneurysm measuring 6.5 x 5.9 cm with mural thrombus seen involving celiac axis and its bifurcation.

• Common hepatic artery and splenic artery seen originating from the aneurysm with ~ 60 – 80 % narrowing of the proximal portion of splenic artery.

• Multiple diverticuli seen in the ascending colon, hepatic flexure, transverse colon, splenic flexure, descending and sigmoid colon.

• Patient refused surgery and was managed conservatively.

FINDINGS

• Causes of celiac artery aneurysm - Atherosclerosis - Trauma - Surgery - Collagen vascular disease - Congenital anomalies However in 40% of cases cause is unknown

DISCUSSION

• Celiac artery aneurysms are one of the rarest forms of splanchnic artery aneurysm. • Anomaly was first described in 1745, fewer than 180 cases have been reported in the international medical literature• The reported incidence of rupture of celiac aneurysms is approximately 15-20%.• Elective treatment should be considered in patients with aneurysms greater than 2 cm.

DISCUSSION

• Variety of treatments had been recommended such as surgical repair, graft and stent placement, endovascular embolization by coils, vascular plugs or glue.

DISCUSSION

Interventional Repair -• This minimally invasive technique is performed by using imaging to guide the catheter and graft inside the patient's artery.• For the procedure, an incision is made in the skin at the groin through which a catheter is passed into the femoral artery and directed to the aneurysm. • Through the catheter , a stent graft that is compressed into a small diameter within the catheter. The stent graft is advanced to the aneurysm, then opened, creating new walls in the blood vessel through which blood flows.

DISCUSSION

SELDINGER NEEDLE

DISCUSSION

• Benefits of Interventional Repair: No abdominal surgical incision No sutures or sutures only at the groins Faster recovery, shorter time in the hospital No general anesthesia in some cases Less pain Reduced complications

Disadvantages of Interventional Repair: Possible movement of the graft after treatment, with blood flow into the aneurysm and resumption of risk of growth/rupture of the aneurysmProbable life-time requirement for follow-up studies to be sure the stent graft is continuing to function
