There is no place for investigative CT scans in patients who have the classical triad of abdominal aortic aneurysm rupture, namely excruciating abdominal pain or backache, a pulsatile mass and hypotension. These patients require immediate surgery. However, in the absence of this triad, CT scans play an important role in the diagnosis of abdominal aortic aneurysm rupture. The CT scan findings will dictate whether the patient requires immediate surgery as in the case of acute rupture, or, whether the surgery can be delayed up to 24 hours to allow for stabilisation and hydration, as in the case of subacute and chronic rupture.

Presented is the case of a patient with recurrent massive upper gastrointestinal hemorrhage. Evaluation during initial hospitalization revealed no definite etiology. During his second hospitalization, he underwent exploratory laparotomy, and an abdominal aortic aneurysm with fistulization into the duodenum was identified. During surgery the patient suffered a cardiopulmonary arrest and could not be resuscitated. This case exemplifies some of the important clinical features that may suggest the diagnosis, including presence of a pulsatile abdominal mass, a peculiarly intermittent or obscure source of bleeding, and the concomitant complaint of back pain and gastrointestinal bleeding.

Between January 1976 and December 1982, 181 patients with abdominal aortic aneurysms were treated surgically, and in 13 patients the aneurysms were found to be inflammatory. Inflammatory aneurysms of the abdominal aorta (IAAA) share important characteristics with typical atherosclerotic abdominal aortic aneurysms. Diagnosis and surgical management of IAAA are distinctive which suggests that IAAA should be considered separately, as a varient of typical abdominal aortic aneurysms. IAAA occur predominantly in males. The presenting symptoms are often idiosyncratic and include severe abdominal or back pain, or both, and ureteral obstruction; the diagnosis of IAAA should be considered when these symptoms are present. Although grossly and microscopically, the perianeurysmal fibrosis resembles idiopathic retroperitoneal fibrosis, the two conditions can be differentiated. At the present time, ultrasonography and computed tomography appear to offer reliable means for diagnosing IAAA. The presence of IAAA, whether established preoperatively or discovered unexpectedly at operation, necessitate certain modifications in the surgical approach, in order to avoid injuring the duodenum and the venous structures. Most patients can be successfully treated by resection and graft replacement. Rupture of the aneurysm in IAAA appears to be less frequent than in typical atherosclerotic abdominal aortic aneurysm.

Rupture of an abdominal aortic aneurysm is readily diagnosed when the triad of abdominal or back pain, shock and a pulsatile abdominal mass are present. Clinical diagnosis can be difficult, however, when patients present with chronic pain and an aneurysm which is not readily palpable. In these patients with confusing abdominal symptoms, CT scan provides a rapid, noninvasive diagnosis. The acute leaking AAA has been documented, but only rarely. This report identifies two patients who ruptured an aortic aneurysm several "months" prior to operation--a "contained chronic" rupture.

Forty-seven patients with an abdominal aortic aneurysm (AAA) and recent onset of abdominal or back pain were evaluated by emergency computed tomography (CT) to identify those patients with a confined rupture, and unstable aneurysm, nonaneurysmal cause of pain and a stable AAA. CT suggested that 25 per cent of these had a confined rupture and should undergo emergency surgical treatment. Rupture was confirmed at operation in one-half of these instances. Thirteen per cent avoided operation since other significant pathologic factors were identified. The remaining 47 per cent benefited from optimal preoperative evaluation and semielective surgical treatment. No patient ruptured an AAA during the delay for complete preoperative evaluation and preparation. Additionally, a preoperative CT is useful to identify patients with an unsuspected iliac, suprarenal, thoracic or inflammatory aneurysm. Thus, we believe that CT has a particularly important role in the evaluation of the symptomatic AAA, adding it to the list of indications for CT evaluation of difficult aortic disorders.

The inflammatory abdominal aortic aneurysm has received little attention in the literature. To date only four reports have addressed the subject specifically. Controversy remains as to whether this is a variant of the usual atherosclerotic aneurysm or a separate entity. The operative reports of 24 patients with inflammatory abdominal aortic aneurysms are reviewed; 21 were intact and 3 ruptured. Intact aneurysms ranged in diameter from 5 to 12 cm and the ruptured ones from 5 to 10 cm. Nine patients with intact aneurysms had symptoms of abdominal or back pain. Of 13 patients who underwent excretory pyelography before operation, only 3 had evidence of obstruction. Nine patients had tube grafts placed, 10 had aortoiliac grafts and 5 aortofemoral grafts. There was one intraoperative duodenal injury and in another patient it was necessary to divide the left renal vein for proximal exposure. No attempt was made to expose the ureters at operation. All patients were discharged from hospital. The authors believe that the inflammatory aneurysm is a variant of the abdominal aortic arteriosclerotic aneurysm. Intraoperative complications can be avoided by the recognition of the pathological features.

Two cases of aortocaval fistula secondary to rupture of abdominal aortic aneurysm were presented. First case was 70 year old man who was admitted with pulsating abdominal mass. Prior to admission, he had been suffering from congestive heart failure. On physical examination, a pulsating mass, remarkable thrill and continuous bruit were recognized on his abdomen. Aortography showed abdominal aortic aneurysm and aortocaval fistula. The fistula (5mm X 3mm) was repaired within the aneurysm controlling the bleeding from the fistula by the direct digital compression. Aortic reconstruction was done with woven dacron bifurcation graft. Postoperative course was uneventful. Second case was 68 year old man who was admitted with the sudden onset of severe back pain. On admission, his physical status was already deteriorated. Diagnosis was made easily by the physical examination. Immediately after aortography, cardiac arrest occurred suddenly. After resuscitation, he was operated in the same manner of the first case. Large fistula (2 cm X 1cm) was noted. This patient died of renal failure and cerebral damage on 30th post operative day. Problems of pre- and post-operative patient management and surgical therapy for aortocaval fistula secondary to rupture of abdominal aortic aneurysm were discussed.

Abdominal aortic aneurysm is a condition affecting nearly 4% of the elderly population. It has a potential for producing a wide range of symptoms, including abdominal pain and back pain. The latter is particularly difficult to interpret in patients with chronic rheumatological conditions, and delayed diagnosis may be associated with a poor outcome. We present a patient with rheumatoid arthritis and chronic low back pain, who developed bilateral leg weakness and hesitancy of micturition, due to an abdominal aortic aneurysm invading the spine.

Acute aortic dissection and abdominal aortic aneurysm presenting as coexistent conditions is rare. We report a patient with a history of hypertension and acute severe back pain who had an acute aortic dissection extending into a preexisting 8 cm abdominal aortic aneurysm that was diagnosed by CT scan. There was no evidence of aortic rupture or leakage. The patient was treated with antihypertensive medication for 2 months to allow maturation of the acute dissection prior to elective repair of the abdominal aortic aneurysm. The repair was constructed to allow continued perfusion of both the true and false lumina by fenestration of the aortic septum at the proximal anastomosis. There were no postoperative complications. This case illustrates an unusual combination of aortic diseases. A management plan is described that safely treats both pathologic conditions.

Inflammatory abdominal aortic aneurysm (IAAA) is a distinct clinicopathological entity, characterized by: (1) clinical presentation, such as back pain, weight loss, and increased ESR, (2) patchy and/or diffuse lymphoplasmacytic infiltration, and (3) marked periaortic fibrosis resulting in thickening of the aneurysmal wall and occasional retroperitoneal fibrosis. Its pathogenesis is unknown, but some authors support the theory that IAAA is a subtype of atherosclerotic abdominal aortic aneurysm because of close relationship between IAAA and atherosclerotic change. In this article, we describe clinical and histological features of IAAA on the basis of the literature and our review of 6 cases of IAAA, emphasizing the similarity and difference between IAAA and atherosclerotic abdominal aortic aneurysm. Our review supports that marked lamellar fibrosis completely replacing the media and adventitia, patchy lymphocytic infiltration (mostly B cells) and endarteritis obliterans are characteristic features of IAAA.
