Intestinal bleeding from abdominal aortic aneurysm is a rare complication; it represents an exceptional occurrence in patients with abdominal aortic prosthesis. The Authors report one case of intestinal hemorrhage caused by interruption in the posterior suture-line between prosthesis and aorta. The hemorrhage has been the cause of death in this patient 4 months after the operation; the exact diagnosis has been recognized only at autopsy, after a gastroduodenal resection performed for a suspected bleeding peptic ulcer. Pathology, ethiology and diagnosis of this case are commented and discussed.

A patient with hiccups was found to have an abdominal aortic aneurysm that subsequently ruptured. We believe that a leaking abdominal aortic aneurysm led to an ileus-induced distention of the splenic flexure of the colon with consequent diaphragmatic irritation and phrenic nerve stimulation. This led to persistent hiccups as a result of repetitive stimulation of the reflex arc mediating hiccups. Persistent hiccups require investigation for an underlying organic etiology, and a leaking abdominal aortic aneurysm should be included in the differential diagnosis.

Seven cases of ureteric obstruction and one case with bilateral medial ureteric deviation complicating inflammatory aneurysm of the aorta are reported. The value of routine preoperative pyelography in all patients with abdominal aortic aneurysm is emphasized. Diagnostic difficulties that may arise when these conditions coexist are discussed. Our experience suggests that these patients are best treated by both aneurysmectomy and ureterolysis and that long-term follow-up is advisable.

On occasions it may be vital to produce controlled thrombosis of an abdominal aortic aneurysm when resection is not possible. A successful technique was evolved to achieve this in a 57-year-old man with malignant lymphoma. The tumor was found to infiltrate massively the retroperitoneum and the wall of a large abdominal aortic aneurysm. The large aneurysm was deemed to be technically unresectable at operation. An approach was devised to thrombose the aneurysm and to proceed safely with chemotherapy of the malignant lymphoma. An axillobifemoral bypass was made with the limbs anastomosed end to end to the common femoral arteries. The external iliac vessels were exteriorized through the abdominal wall. The aneurysmal sac outflow was occluded by balloon catheters introduced through the exteriorized iliac vessels. A right transaxillary catheter was inserted and placed at the level of the renal arteries to induce and to control the progress of thrombus formation in such a way as to ensure patency of the renal vessels. Thrombin was delivered into the sac via this transaxillary catheter. A high urinary output was maintained. Serial angiograms of the clotting process were obtained. Once the sac was thrombosed, the balloon catheters were removed and a final angiogram was obtained which demonstrated the obliteration of the aneurysmal sac and the patency of the renal vessels. The patient has been fully employed for 20 months.

One hundred and twelve cases of primary aortoduodenal fistulas were reviewed. The most common etiological agent was an atherosclerotic infrarenal abdominal aortic aneurysm. There was a male to female predominance of 9:2 with an average age of 62 years. Most fistulas occurred between an infrarenal aneurysm and the third portion of the duodenum because of the relatively fixed position of the duodenum and its direct anatomical relationship posteriorly with the aorta. Patient symptoms may vary from abdominal or back pain with gastro-intestinal bleeding to just hematemesis or melena. Twenty per cent gave a history of abdominal aneurysm while up to 70% may have an abdominal mass on physical examination at the time of admission. Tentative diagnosis is established by history and physical examination with duodenoscopy, barium duodenogram and angiography available only if temporally feasible. Surgical exploration is the only treatment with resection of the aneurysm, synthetic graft placement and duodenal suturing as the procedure of choice.

The effectiveness of an intravenous nutritional program plus aggressive dialysis was studied in 32 patients with renal failure following ruptured abdominal aortic aneurysm. Each patient was managed postoperatively with a renal failure fluid regimen, consisting of the eight essential amino acids plus dextrose in conjunction with peritoneal dialysis and hemodialysis. This regimen induced salutary metabolic effects temporarily improving the patient's condition in most instances. No technical or septic complications associated with the intravenous dietary therapy occurred. However, the incidence of recovery of renal function was low, and the overall patient survival was only 12.5%. The experience indicates that although this program has been shown to be efficacious in some patients with acute renal failure, it seems of little benefit in those whose renal failure follows ruptured aortic aneurysm.

Because of the importance of size in the decision for elective operation in patients with abdominal aortic aneurysm (AAA) and the need to identify accurately even small aneurysms, a prospective study was carried out to compare currently available diagnostic methods. A series of 78 patients with AAA underwent evaluation by physical examination, lateral lumbar spine X-ray, aortic ultrasound, and aortography. Measurements were compared to aneurysm size at operation. Physical examination was most variable, and tended to overestimate size by approximately 20%. Lateral spine X-ray was useful in three of every four patients and in these cases it was reliable and reasonably accurate. Ultrasonography was most widely applicable and very reliable for diagnosis. Its tendency to underestimate aneurysm size in our experience may be improved by use of gray-scale units, which better define aneurysm wall thickness. The anatomic information provided by aortography was of great value in the surgical management of patients with AAA, but aortography was of limited value in accurate measurement and should not be employed for this purpose.

Forty-eight patients undergoing elective repair of an abdominal aortic aneurysm were randomly selected for correlation of diagnosis of aneurysm and aneurysm size as determined by direct surgical measurements, ultrasound examination, and lumbar spine X-ray. The preoperative diagnosis was confirmed by lumbar spine plain films in 72% of patients and by B-mode ultrasound in all of patients. Aneurysm size could be measured by lumbar spine X-ray in 55% of patients and with gray-scale B-mode ultrasound in all of patients. The average difference between surgically measured and roentogenographically determined aneurysm size was 1.5 cm in the transverse diameter and 0.87 cm in the anteroposterior diameter of the aneurysm. The average difference between surgically measured aneurysm size and ultrasound-determined external wall diameter of the aneurysm was 0.42 cm in the transverse diameter and 0.29 cm in the anteroposterior diameter. From these data we conclude that gray-scale B-mode ultrasound of the aorta is a more sensitive and accurate method of assessing abdominal aortic aneurysms than is the use of lumbar spine X-ray.

In a hypercholesterolemic Lebanese family, an uncommon Gm haplotype carrying an unexpected C gamma 1 gene was inherited by only one of 10 siblings. A new recombination during the maternal or paternal meiosis could explain its formation. According to this hypothesis, our data would be informative for the linkage relationship between the gamma-cistrons and the alpha 2-cistron. The latter might be located near the N-terminal side of the gamma-cistron linkage group, and the sequence of genes would be alpha 2, gamma 4, gamma 3, and gamma 1. A mutation could also effect the change from G1m(17) (codons AAA and AAG) TO G1m(3) (codons AGA and AGG). Another alternative is to postulate a constitutive expression of a C gamma 1 structural gene which, normally, would not be expressed. The uncommon derepression could be the consequence of uncommon cellular response to environmental, pathological or metabolic perturbation of a regulatory mechanism.

Four cases of ruptured abdominal aortic aneurysm producing retroperitoneal radiolucent shadows are presented. Gross and microscopic examination showed this to be due to dissection of blood through the retroperitoneal fat. This finding has been helpful in confirming the presence of retroperitoneal hemorrhage.
