Retroperitoneal Aortobifemoral Bypass by a Combination of Horseshoe Kidney and Aortoiliac Occlusive Disease with Stent Thrombosis

Bilateral aorto-profunda femoris bypass with Dacron bifurcation graft was performed by a patient with aortoiliac occlusive disease (AIOD) and horseshoe kidney (HSK) who had undergone stenting of the right common iliac artery and of the left superficial femoral artery with subsequent stent thrombosis as well as significant subrenal aortic stenosis. As endovascular treatment was not feasible and surgical treatment by means of transperitoneal incision would be associated with high risk of damage to the HSK, the operation was successfully accomplished through left pararectal retroperitoneal approach.     

Isolated Iliac Artery Aneurysm Caused by Fibromuscular Dysplasia: Report of a Case

Fibromuscular dysplasia (FMD) can develop in many different arteries, but iliac artery aneurysms are rare. A 69-year-old Japanese woman was admitted to our hospital for treatment of a right common iliac artery aneurysm. Aortography revealed aneurysms in both the right common iliac artery and the left internal iliac artery. Notably, the right common iliac artery aneurysm had a string-of-beads appearance. At surgery, the aneurysms were resected, and replaced with Y-shaped vascular prostheses. The histopathological diagnosis was fibromuscular dysplasia (FMD). We report this case of common iliac artery aneurysm caused by FMD due to its rarity.

Left Retroperitoneal Approach Using a Retractor to Repair Abdominal Aortic Aneurysms: A Comparison with the Transperitoneal Approach

Abstract. Purpose: The purpose of this study was to compare the effectiveness of the retroperitoneal approach (RP) using a Thompson retractor with the conventional transperitoneal approach (TP), to repair infrarenal abdominal aortic aneurysms (AAA). Methods: A total of 91 consecutive patients were divided into two groups; group A (n= 21) underwent surgery using the TP, and group B (n= 70) underwent surgery using the RP with a Thompson retractor. Results: There were no significant differences in the operation time, aortic cross-clamp time, incidence of postoperative cardiac events, or the development of wound complications; however, a significantly higher rate of postoperative respiratory complications and ileus was observed in group A. Moreover, oral feeding was commenced later and the hospital stay was prolonged in group A (P < 0.01). Conclusion: These findings clearly demonstrate that our RP method, especially when using a Thompson retractor, is a preferable alternative to TP for AAA surgery.

Bleeding Prolapsed Hemorrhoids as a Presentation of Ruptured Internal Iliac Artery Aneurysm: Report of a Case

Internal iliac artery aneurysms (IIAAs) are rare and their concealed location in the pelvis presents a diagnostic challenge. We report a case of a 79-year-old man who presented 12 years after an abdominal aortic aneurysm repair, with signs of prolapse, bleeding, hemorrhoids, and a deep vein thrombosis. His condition rapidly deteriorated, with the development of acute renal failure and obvious perianal and perineal ecchymoses, within a few days. Abdominal ultrasound and computed tomography showed a ruptured IIAA. His renal function returned to normal after surgical decompression of the aneurysm.     

腋-股架桥术治疗髂、股动脉闭塞性疾病

Iliac artery stenosis masquerading as diuretic resistant congestive heart failure

Iliac artery stenosis is a rare cause of renal dysfunction in renal allograft recipients. Its presence can mimic renovascular hypertension and yet alter the very radiologic tests used to diagnose renal artery stenosis. We investigate a case of iliac artery stenosis that presented with diuretic resistant fluid overload, hypertension and limb claudication that exposed the pitfalls in the diagnosis and management of this condition. Successful stent placement, 8 months after transplant, resulted in return of the serum creatinine below the post-transplant nadir.     

An Internal Iliac Artery Aneurysm Causing a Colonic Obstruction: Report of a Case

An 80-year-old male patient presented with the chief complaints of a sudden onset of pain in the right lower quadrant and constipation of 3 days' duration. In computerized tomographic examination an aneurysm of right internal iliac artery and an abnormally enlarged descending colon were seen. During an emergency operation a small rupture in the subserosa of the rectosigmoid junction was found. Received: July 27, 2000 / Accepted: March 6, 2001     

Simultaneous Surgical Treatment of Abdominal Aortic Aneurysm and Bilateral Aneurysms of the Internal Iliac Artery

Introduction: The purpose of this study is to present our experience in the management of patients with abdominal aortic aneurysms (AaA) and aneurysms in both the internal iliac arteries (IIA) at the same time. Methods: Between 2000 and 2005, a series of 13 patients with AAA and also aneurysms in both the IIA, were treated in our clinic. They were all men with a mean age of 74 years. The size of the IIA aneurysms (IIAA) ranged from 2.0 to 8.0 cm (mean, 3.4 cm). All patients underwent an aneurysmatectomy of the AAA and placement of a prosthetic bifurcated aorto-biiliac or-bifemoral bypass, by a transperitoneal approach. The management of one of the two IIAA was the aneurysmatectomy and the direct revascularization of the healthy peripheral portion of the remaining IIA with the ipsilateral leg of the aorto-biiliac bypass. The other IIAA was treated with proximal ligation of its neck and aneurys-morraphy.

Results: No patient died during the first 30 postoperative days. Morbidity was about 7.7% (one patient suffered from ‘trash foot’, which was treated successfully with conservative measures). Finally, the mean stay in hospital was 7 days and no patient clinically presented symptoms of pelvic or colonic ischaemia.

Conclusions: Simultaneous treatment of AAA and bilateral IIA aneurysms is a technically difficult, but safe procedure, if it is performed meticulously. Revascularization of at least one internal iliac artery is strongly recommended in order to avoid dangerous complications, such as pelvic or colonic ischaemia.     

Preoperative Internal Iliac Artery Coil Embolization for Aneurysms Involving the Iliac Bifurcation

Endovascular repair of abdominal aortic aneurysms involving the iliac artery, which is seen in about 20% of patients, requires extension of the stent-graft limb into the external iliac artery.

Occlusion of the IIA is used to prevent a potential type II endoleak via retrograde flow in the IIA after covering the IIA origin with a stent-graft limb.

In this article, the major indications for coil-embolization of the internal iliac artery in aneurysmal disease are reviewed and discussed, as well as the technique and the outcome regarding endoleak incidence and complications.     

Successful Treatment of a Patient with a Severely Calcified Aorta by an Ascending Aorta to Iliac Artery Graft – A Case Report

Coral reef aorta is a rare, unique entity with extensive calcification of the entire aorta, mainly the supra- and juxtarenal part. The main symptoms are lower limb claudication, hypertension, deterioration of renal function and angina abdominalis.We report a case of successful treatment of a patient with a coral reef aorta by an ascending aorta to iliac artery bypass graft. Five years later the descending aorta was found to be completely occluded with visceral and distal perfusion via the bypass only.     

Surgical Treatment of Aortoiliac Occlusive Disease with Concomitant Superficial Femoral Artery Occlusion

Introduction: Aortofemoral bypass is a standard method for the surgical treatment of aortoiliac occlusive disease. Most of the patients with aortoiliac occlusive disease have multisegment arterial occlusions extending to the popliteal or distal arterial system. In this research early and long term results of aortobifemoral bypass and aortobifemo-ral bypass with combined femoropopliteal bypass were assessed.

Patients and Methods: From March 2002 to October 2011, 833 patients underwent bypass procedures for aortoiliac occlusive disease with concomitant superficial femoral artery occlusion. The patients and surgical procedures were studied prospectively. The patients were divided into 2 groups. Group I (n: 632) consisted of patients who only recevied aortobifemoral bypass. Group II (n: 201) comprised of patients in whom aortobifemoral bypass was combined with femoro-popliteal bypass.

Results: In the early (30 days) and late (42 months) follow up periods, the rate of amputation (8 patients in Group I vs. 16 patients in Group II in the early period; p < 0.05 and 8 patients in Group I vs. 11patients in Group II in the late follow-up; p < 0.05) and mortality (2 patients in Group I and 5 patients in Group II in the early period and 8 patients in Group I vs. 11 patients in Group II in the late follow-up; p < 0.05) were higher in Group II. Moreover, graft patency (0.4% thrombosis rate in Group I vs. 5.4% thrombosis rate in Group II in the long run; p < 0.05), freedom from symptoms (claudication, rest pain and necrosis, 3 patients vs. 9 patients, 9 patients vs. 27 patients and 8 patients vs. 17 patients in Group I and Group II, respectively in the longterm follow-up; p < 0.05) and consequences (mortality, amputation, graft infection and graft extraction rates in the longterm, all p < 0.05) were significantly lower in Group II. Conclusion: Aortobifemoral bypass procedure is an efficient, safe and durable technique for the surgical management of aortoiliac occlusive disease (AIOD) combined with superficial femoral artery occlusion. In this circumstance profunda femoris artery plays the major role for the perfusion of limb.
