Ruptured iliac aneurysms.

Iliac aneurysms are uncommon as compared with aneurysms of the abdominal aorta. Rupture is the most serious complication of aneurysms of both vessels. Considerable attention has been focused on the management of ruptured abdomonal aortic aneurysms, but ruptured iliac aneurysms have received little notice. The problems in the management of ten ruptured iliac aneurysms, seen over the last five years, together with the rarity of other reports of this condition, have stimulated this review.

Isolated iliac aneurysms.

Isolated iliac aneurysms are relatively infrequent, often difficult to detect and therefore rarely considered in the differential diagnosis. Because of their close anatomical relationship to the ureters, bladder, colon, pelvic veins, femoral and sciatic nerve roots one is often misled. The consequences can be grave; chronic ureteric obstruction for instance can cause damage to one or both kidneys. With the growing frequency of tube grafting for aortic aneurysms it becomes increasingly important to consider the prevalence and incidence of isolated iliac aneurysms. The aim of this study is to report the incidence, clinical course and outcome of these lesions. In a consecutive series of 678 aorto-iliac aneurysms in the years 1972-1988 there were 53 isolated iliac aneurysms (7%) ranging in size from 3.5-14 cm whereas the reported incidence in the literature lies between 1-2%; the prevalence in consecutive autopsy series is even less than 1%. CT scanning proved to be the gold standard for the evaluation of pelvic aneurysmal disease whilst angiograms were of little help. A palpable mass was present in nine cases; GI-tract signs in 12 (five patients being operated on for suspicion of appendicitis or sigmoiditis), the genito-urinary tract was involved in eight cases, sciatic or femoral root nerve compression occurred in seven, recurrent pulmonary embolism in two, lower extremity ischaemia in seven and a-v fistula in one. The male:female ratio was 51:2 and that of ruptured to non-ruptured aneurysms 15:38. The site of isolated iliac aneurysms was the common and/or the internal iliac artery uni- or bilaterally. The external iliac artery was never involved.(ABSTRACT TRUNCATED AT 250 WORDS)

Successful treatment of bilateral deep femoral aneurysms and multiple iliac aneurysms associated with severe aortic valve disease: report of a case.

We report herein the case of a patient in whom aneurysms of the bilateral deep femoral arteries (DFA) and multiple iliac aneurysms associated with severe aortic valve disease were successfully treated by a two-staged operation. The patient was a 74-year-old man who had dense calcification of the ascending aorta and aortic arch. Prior to aortic valve replacement (AVR), the aneurysms of the DFA and internal iliac arteries were resected. The terminal end of the abdominal aorta and bilateral common iliac arteries were then reconstructed with a Y graft to be used as a possible alternative arterial input route in place of the ascending aorta for extracorporeal circulation during the AVR. The inferior mesenteric artery (IMA) was well developed, and the external iliac arteries and their branches were preserved at aneurysmectomy. Postoperatively, there was no ischemia of the pelvic organs or the hip muscles. The AVR was subsequently performed 5 weeks after the first operation, and the patient was discharged after an uneventful postoperative course.

[Ureteral obstruction secondary to inflammatory iliac aneurysm].

Inflammatory iliac aneurysms are uncommon and account for 1-2% of total abdominal aneurysms. These aneurysms are more susceptible to present urological symptoms and are difficult to diagnose because of their uncommon incidence and location in the deep pelvis which makes them little accessible to physical examination. This case report presents one patient with right obstructive uropathy secondary to extrinsic ureteral trapping due to inflammatory iliac aneurysm which evolved favourably after ureterolysis, endoaneurysmectomy and interposition of aortoiliac graft. A brief review of diagnostic and therapeutic aspects in the literature is included. The relevance of a high degree of suspicion to diagnose this entity in patients with otherwise explainable vesical irritative symptoms, haematuria or renal failure is highlighted.

[Surgical management of isolated iliac aneurysms].

Isolated iliac aneurysms (IIA) are uncommon lesions that require surgical repair to prevent rupture. The aim of this article is to give an update on the current surgical management of IIA. This report also evaluates the application of endovascular repair in IIA, based on a recent Pubmed search and on our own experience in the interventional field: Open reconstruction achieves good longterm results and still represents the golden standard in surgical treatment of IIA. Transluminally placed endovascular stent grafts can be successfully used to exclude isolated iliac aneurysms in selected high risk patients with suitable anatomy. A classification based on aneurysm morphology is useful for patient selection. The value of endovascular therapy has yet to be determined.

Aorto-iliac aneurysms rupturing into the iliac veins.

BACKGROUND: Rupture of aorto-iliac aneurysms into the iliac veins is seldom reported in distinct series, and represents only a fraction of ruptures into the abdominal cavity. MATERIAL AND METHODS: Four cases are reported: two aortic aneurysms ruptured into the right iliac vein, one right iliac aneurysm ruptured into the right iliac vein, one right iliac aneurysm ruptured into the cava at the bifurcation, one aortoiliac aneurysm ruptured into the right iliac vein. Two patients showed severe shock at admission. Central venous pressure at operation was 43.6 +/- 26.3 cmH2O, and rapidly decreased at aortic clamping. Venous bleeding was controlled by finger compression of the iliac and caval vein and aortic graft replacement followed direct suture repair of the venous breach. De Weese caval clip was implanted twice, to prevent pulmonary embolism in severely compromised iliac veins. This series represents 1% among 373 ruptured abdominal aortic aneurysms operated on as emergencies over the same period. RESULTS: Pulmonary embolism, either paradoxical or postoperative, never occurred. Mortality rate was 25%, compared to 35% overall mortality among the whole ruptured group. The role of the site of rupture is swelling of the lower limbs is suggested, and edema can be suggestive though statistical evidence has not been achieved. CONCLUSIONS: Three concepts are stressed: early diagnosis and operation (i.e. before cardiac high output failure and shock); accurate as well as simple surgical technique; careful post-operative intensive care.

[Arteriovenous and arterial-digestive system fistulas complicating isolated iliac aneurysm].

Isolated iliac aneurysms are often discovered when they rupture, sometimes into a neighbouring organ. We report 2 cases of aneurysm of the common iliac artery, one which ruptured into the right common iliac vein and the other in to the sigmoid. Diagnosis was made at laparotomy in the first case and on the CT-scan of the pelvis in the second. The first case was treated with an exclusion graft using ilio-iliac bypass with suture of the venous breach via the aneurysm. In the second case, the aneurysm was excluded by ligature of the iliac arteries with extra-anatomic crossed femoro-femoral bypass, sigmoid colostomy and drainage of the pelvis. These two cases illustrate the importance of digital examination of the pelvis and CT-scan for the diagnosis of complicated aneurysms of the iliac vessels. Rapid surgery is a determining factor in prognosis.

[Rupture of an isolated iliac aneurysm].

Isolated iliac artery aneurysm threatening to rupture is a rare condition with a poor prognosis if not dealt with by the physician in a brisk and effective manner. Symptoms from an iliac aneurysm can masquerade as a range of symptoms from neighbouring organs or be almost asymptomatic before rupturing. A case of a 81 year old man, with symptoms of dizziness, fatigue and light lower abdominal pain, who developed sudden cardiovascular collapse, is presented.

[Isolated iliac aneurysms].

An isolated iliac aneurysm is an uncommon entity with a relative incidence to abdominal aortic aneurysm of 0.9 to 1.9 percent. Analysis of 16 cases with 20 isolated iliac aneurysms experienced at our vascular service makes the basis of this report. Seventeen aneurysms involved the common iliac artery, two the internal iliac artery and one the external iliac artery. As we experienced 341 abdominal aortic aneurysms during the same period, relative incidence of isolated iliac aneurysm to abdominal aortic aneurysm was 4.7 percent. Fifteen of the 16 cases were male; isolated iliac aneurysms had significantly higher preponderance for the male. Six of the cases were presented with ruptured aneurysms, giving a rupture rate of 37.5 percent. This rupture rate was significantly higher than that of abdominal aortic aneurysms of 11.1 percent. Operation was performed on 15 patients; the remaining one died before surgery. Although there was no operative death among the elective cases, three patients in the ruptured group died postoperatively giving a mortality rate of 60 percent. The least diameter of the ruptured aneurysms was 3.5 centimeter. Among the 16 patients 5 presented with a ruptured aneurysm and 3 had no symptoms related to the aneurysm. Five patients complained of a pulsatile abdominal mass. Two of the ruptured aneurysms were associated with an iliac arteriovenous fistula. Both of them involved the common iliac artery. Although emergency operation was performed on one of them, he died of acute renal failure due to preoperative dehydration and hypovolemia. The another one was operated on electively after intensive medical treatment for heart failure and the patient survived.(ABSTRACT TRUNCATED AT 250 WORDS)

Successful endovascular treatment of a ruptured internal iliac aneurysm.

Internal iliac artery aneurysms (IIAs) are rare but can be the source of considerable morbidity when rupture occurs. IIAs have traditionally been treated with direct surgical exclusion or ligation. More recently, the advent of endovascular techniques have been adapted to treat isolated common and IIAs in lieu of elective surgical correction. This case report describes an 81-year-old patient with multiple medical problems and a symptomatic IIA, initially diagnosed with computed tomographic scan. Arteriography results showed extravasation of contrast from a left IIA. The aneurysm was treated with endovascular exclusion, with multiple coils in the IIA followed by placement of a covered stent within the common and external iliacs to exclude the orifice of the IIA. The patient tolerated the procedure well, and at 2 months after the procedure, no endoleak was present on follow-up computed tomographic scan results. At 12 months postprocedure, the patient has remained well. This case shows that endovascular therapies may offer a good treatment option in symptomatic or ruptured IIA, particularly in a patient who is at poor operative risk.

Perineal bruising: a sinister sign for leaking iliac aneurysms?

Ruptured false iliac aneurysms carry high mortality of up to 57%. It should be suspected whenever a patient who had previous aortic aneurysm repaired presents with bizarre lower abdominal symptoms. In the literature, different presentations have been reported, e.g progressive hydronephrosis, small intestinal obstruction, chronic venous insufficiency, arterio-venous fistula, and gross haematuria from arterio-vesical fistula. We report a patient suffering from a ruptured iliac aneurysm associated with a new sign that has not been described hitherto: perineal bruising.

An alternative to aorto-uni-iliac EVAR and femoro-femoral crossover in a patient having an aorto-iliac aneurysm with an occluded external iliac artery.

INTRODUCTION: An endovascular procedure for excluding an aorto-iliac aneurysm whilst simultaneously preserving one internal iliac artery is described in a patient with complex iliac pathology. REPORT: The procedure involved the use of Advanta V12 covered stents to bridge the gap between the contralateral limb of the main body of a custom-made Zenith stent graft and the internal iliac artery on the side of an external iliac artery occlusion. DISCUSSION: Minimal modifications to the standard design of modular stent grafts make it possible to treat high risk patient with complex pathology with minimal morbidity.

Does the presence of an iliac aneurysm affect outcome of endoluminal AAA repair? An analysis of 336 cases.

OBJECTIVE: To determine whether the presence of an iliac aneurysm compromises outcome of endovascular exclusion of AAA and to ascertain the fate of the iliac aneurysmal sac. PATIENTS AND METHODS: Between April 1997 and March 2001, data on 336 consecutive patients undergoing endovascular repair for AAA were entered in a prospective database. Suitability for endovascular repair was assessed by preoperative contrast-enhanced computed tomography. A maximum common iliac artery (CIA) diameter > or = 20 mm was defined as iliac aneurysm. Patients with and without iliac aneurysms were compared to early (immediate conversion or perioperative death) and late failure (increase in aneurysm diameter or persisting graft-related endoleak, or late AAA rupture or conversion). RESULTS: Fifty-nine patients (18%) had iliac aneurysms, 19 were bilateral, for a total of 78 aneurysmal iliac arteries (median diameter 23 mm; range 20-50 mm). A distal seal was achieved by landing in 33 external iliac arteries, in 20 ectatic CIAs, and in 25 normal CIAs. Operating time differed significantly between patients with and without CIA aneurysms (153 +/- 71 vs 123 +/- 55 min, p = 0.0001), whereas no statistically significant differences were found with respect to early and late failure (2% vs 3%, p = 0.5 and 14% vs 8%, p = 0.11, respectively). There were no cases of buttock or colon necrosis. At a median follow-up of 14 months (range 0-46; i.q.r. 7-27 months) common iliac diameter decreased > or = 2 mm in 49 cases, remained stable in 25, and increased > or = 2 mm in 3. CONCLUSION: The presence of iliac aneurysm rendered endoluminal AAA repair more complex but did not affect feasibility and long-term outcome of the procedure. In our experience internal iliac exclusion was never associated with significant morbidity. These data may be useful when considering endovascular repair in high-risk patients with challenging anatomy.
