Aneurisma aislado y asintomático en la arteria ilíaca común derecha / Isolated and asymptomatic aneurysm in the right common iliac artery

Los aneurismas de la arteria ilíaca aislados son extremadamente raros y representan solo entre el 2 por ciento y el 7 por ciento de todos los aneurismas intraabdominales. Este artículo tuvo como objetivo asociar los criterios actuales para el tratamiento quirúrgico en los aneurismas aislados y asintomáticos en la arteria ilíaca común. Se presenta un paciente masculino de 62 años, fumador, remitido del departamento de radiología, porque se observó en el ultrasonido abdominal dilatación aneurismática en arteria ilíaca común derecha. En la tomografía computarizada contrastada se confirmó aneurisma aislado con diámetros quirúrgicos. Se decidió operar y se realizó aneurismectomía más injerto por sustitución protésica con dacrón ilio-ilíaco, con una evolución clínica posoperatoria inmediata y tardía satisfactoria. El tratamiento de referencia para el aneurisma de la arteria ilíaca común ha sido la reparación quirúrgica abierta con injertos protésicos. El algoritmo de decisión se basó en el riesgo de ruptura, que depende a su vez del diámetro aneurismático y del ritmo de crecimiento. Actualmente, el umbral para la reparación electiva de la arteria ilíaca aislada puede considerarse con un mínimo de 3,5 cm de diámetro, pero existe nueva evidencia científica de que muchos pacientes pueden someterse a un tratamiento innecesario si se utiliza este diámetro. Esta es una entidad especial, no solo por su infrecuencia sino también por la mayor complejidad de su reparación(AU)

Isolated iliac artery aneurysms are extremely rare and account for only 2 percent to 7 percent of all intra-abdominal aneurysms. This article aimed to associate current criteria for surgical treatment in isolated and asymptomatic aneurysms in the common iliac artery. A 62-year-old male patient, smoker, referred from the radiology department, is presented because aneurysmal dilation was observed in the abdominal ultrasound in the right common iliac artery. The contrasted computed tomography confirmed an isolated aneurysm with surgical diameters. It was decided to operate and aneurysmectomy plus grafting was performed by prosthetic replacement with ilio-iliac dacron, with a satisfactory immediate and late postoperative clinical evolution. The reference treatment for common iliac artery aneurysm has been open surgical repair with prosthetic grafts. The decision algorithm was based on the risk of rupture, which in turn depends on the aneurysmal diameter and the rate of growth. Currently, the threshold for elective repair of the isolated iliac artery can be considered to be a minimum of 3.5 cm in diameter, but there is new scientific evidence that many patients may undergo unnecessary treatment if this diameter is used. This is a special entity, not only because of its infrequency but also because of the higher complexity of its repair(AU)

Comparison of temporary occlusion of abdominal aorta, temporary occlusion of common iliac artery and internal iliac artery ligation in the treatment of complex acetabular fracture / 中华创伤骨科杂志

Objective To compare the effectiveness of controlling blood loss in the treatment of complex acetabular fracture between temporary occlusion of abdominal aorta by interventional balloon (TOAAIB),temporary occlusion of common iliac artery by interventional balloon (TOCAIIB) and internal iliac artery ligation (IIAL).Methods Included for this study were 113 complex acetabular fractures which had been treated at Department of Orthopaedic Trauma,Shaoguang Hospital Affiliated to Southern Medical University from January 2000 through January 2017.There were 68 males and 45 females,aged from 23 to 61 years (average,42.3 years).According to the Letournel classification,all of them belonged to complex fractures,including 10 T-type,24 double-column,16 posterior column & posterior wall,46 transverse & posterior wall and 15 anterior & posterior half-transverse ones.They were all treated by open reduction and internal fixation but differed in surgical hemostasis techniques:TOAAIB was used in 37cases,TOCAIIB in 31 and IIAL in 45.Fracture reduction was evaluated by Matta criteria.Intraoperative bleeding and postoperative wound drainage,fracture union and complications related to interventions were recorded.Hip function was evaluated by Modified d'Aubigne & Postal clinical grading system after fracture healing.Results The 3 groups (TOAAIB,TOCAIIB and IIAL) were comparable because there were no significant differences in gender,age,time from injury to surgery,Letournel classification or surgical approaches between the patients in the 3 groups (P ＞ 0.05).Anatomical reduction was achieved in 91.15％ of the patients (103/113) and satisfactory reduction in 8.85％ (10/113).Intraoperative hemorrhage was 1,631.5 ±675.5 mL in the HAL group,892.6 ±217.7 mL in the TOCAIIB group and 648.0 ± 170.2 mL in the TOAAIB group,showing significant differences between the 3 groups (P ＜ 0.05).One case of femoral artery thrombosis occurred in the TOAAIB group at the end of operation but was cured by symptomatic treatment of anticoagulation.There were no interventional complications in the other 2 groups.There were no significant differences between the 3 groups in postoperative wound drainage,fracture union time,hip function score or complications (P ＞ 0.05).Conclusions In controlling intraoperative bleeding in the surgery for complex acetabular fracture,TOAAIB may be the best,followed by TOCAIIB,and IIAL may be the worst.However,choice of a proper surgical hemostasis technique should also depend on the specific intraoperative condition of a specific patient.

Aortoiliac Occlusive Disease as a Cause of Allograft Kidney Dysfunction and Refractory Hypertension / 고신대학교의과대학학술지

Aortoiliac occlusive disease (AIOD), especially proximal to the transplant artery, in kidney transplant patient activates the renin-angiotensin-aldosterone system by limiting graft renal perfusion and causes symptoms that can occur with transplant renal artery stenosis (TRAS) such as refractory hypertension, water retention, and graft renal dysfunction. Immediate clinical suspicion is difficult due to the nature of the progressive disease unlike TRAS. Herein, we present an interesting case of bilateral common iliac artery occlusion (AIOD, TASC II, type C) that manifested as uncontrolled blood pressure and decreased allograft function in a patient who had kidney transplant 17 years ago. The patient was successfully diagnosed with duplex scan, ankle-brachial index (ABI) and computed tomography angiography and treated with percutaneous luminal angioplasty and stent graft insertion.

An Inferior Mesenteric Artery Arising From The Left Common Iliac Artery

Although anatomical variations in abdominal vascular branching are a common phenomenon, alternations inIMA are rather rare. We report a variation found during a dissection of an embalmed male cadaver of CaucasianHellenic origin, where we observed an IMA having as a point of origin the left common iliac artery, 0.4 cm afterthe AA bifurcation in the level between L3 and L4 vertebra. Ignorance of this variant may cause serious implicationsduring vascular and abdominal surgery

Endovascular Repair of a Common Iliac Artery Aneurysm and Arteriovenous Fistula with Congestive Heart Failure / 日本心臓血管外科学会雑誌

<p>We report a case of endovascular surgery in a patient of common iliac artery aneurysm with arteriovenous (A-V) fistula. A 60-year-old woman was admitted because of dyspnea. She had a clinical history of lumbar disk surgery at age of 40. On physical examination, we detected a pulsatile mass and pansystolic murmurs in her left lower abdomen. A chest X-ray film demonstrated severe cardiomegaly with 70% of cardiothoracic ratio. Contrast-enhanced CT revealed left common artery aneurysm with A-V fistula between the left common iliac artery and the left common iliac vein. Three-dimensional CT showed hyper-vascularity in the region from the pelvic vein to IVC. We considered that she had high risk of intraoperative massive bleeding for open abdominal surgery. We conducted endovascular repair for this iliac artery aneurysm with A-V fistula by the GORE EXCLUDER C3^® stent graft system. Postoperative contrast-enhanced CT showed complete exclusion of both left common iliac artery aneurysm and A-V fistula. After surgery, her symptoms improved significantly.</p>

The application of temporary balloon occlusion of the common iliac artery in patients with pernicious placenta previa and placenta accreta / 实用放射学杂志

Objective To investigate the clinical application of temporary balloon occlusion of the common iliac artery in performing cesarean section for patients with pernicious placenta previa and placenta accreta.Methods A total of five cases with ultrasound or MRI diagnosed pernicious placenta previa and placenta accreta were analyzed retrospectively.One of the cases was diagnosed Rh(-)blood type.Prophylactic temporary balloon implantation in bilateral common iliac arteries were carried out before cesarean section.Digital subtraction angiography ensured the position of balloon catheter and the catheter was fixed.The balloon was inflated immediately after the removal of the fetus.The balloon was removed at 6-8 hours after the cesarean section.The amount of blood loss,transfusion requirement,cesarean hysterectomy rate, and X-ray exposured time and dose during the procedure were recorded.Results Temporary balloon implantation in bilateral common iliac arteries in all five patients were obtained successfully.The blood loss was seen <500 mL in one patient and 500-1 000 mL in other four patients.Because of placenta implantation over depth of serosa and placenta percreta in one case,massive intractable hemorrhage occurred in short time,partial hysterectomy had to be carried out.The uterus was retained in other four cases.Conclusion The temporary balloon occlusion of the common iliac artery in performing cesarean section is a safe and effective technique,and it can reduce the amount of blood loss,transfusion requirement and secondary risk due to uncontrollable bleeding during surgery.

Asymptomatic Common Iliac Artery Stenosis as a Cause of Renal Allograft Dysfunction and Uncontrolled Hypertension / 대한이식학회지

Occlusive disease of the iliac segment, proximal to the transplant artery (prox-TRAS), in kidney transplant recipients is a rare complication. Prox-TRAS, located in the common iliac artery, is extremely rare in these patients. Herein, we present an interesting case of a common iliac artery stenosis that manifested as decreased allograft function and uncontrolled blood pressure without other typical clinical symptoms. The patient was successfully treated with percutaneous luminal angioplasty and stent insertion.

The Changes of Pro-inflammatory Cytokines in Serum according to the Reperfusion Time after Ischemia of Left Common Iliac Artery in Mice / 체질인류학회지

Ischemia-reperfusion injury arises from the restoration of blood supply after ischemia. Both reactive oxygen species and various cytokines produced by activated immune cells are the primary causal risk factors for ischemic injury. Cytokines are intercellular signaling substances for regulating any infection, immune reactions and inflammation, and pro-inflammatory cytokines adversely affect any diseases through an increase in inflammatory reaction. This study was conducted to investigate whether the periods of reperfusion after ischemia result in any changes of pro-inflammatory cytokines in the serum, including IL-1α, IL-1β, IL-2, IL-3, IL-5, IL-6, Eotaxin, MCP-1, MDC, MIP-1α, RANTES, TARC, IFNδ. A total of 96 male mice aged at 12 weeks was used in this study, and the groups of ischemia were divided into the following three different groups: 2-hour, 4-hour, and 6-hour ischemia groups. For the object of ischemic injury, the left common iliac artery was clamped by vascular clamp, each ischemia group was subdivided into 5 different groups according to the periods of reperfusion: 0-, 2-, 4-, 8-, and 16-hour reperfusion time. Blood samples after general anesthesia were collected from the mice hearts, and the serum was separated from them. The concentration of pro-inflammatory cytokines (IL-1α, IL-1β, IL-2, IL-3, IL-5, IL-6, Eotaxin, MCP-1, MDC, MIP-1α, RANTES, TARC, IFNδ) in the serum was measured by ELISA, and the following results were acquired. The concentrations of the 13 pro-inflammatory cytokines were significantly different in accordance with the periods of ischemia and the reperfusion time. In 2-hour ischemia group, IL-1α and IL-3 were increaed compared to normal control group, and 12 cytokines were increased followed by reperfusion except for MIP-1α. MCP-1 and TARC were expressed as the highest concentration in the 16-hour reperfusion time. In 4-hour ischemia group, TARC was significant differences with normal control group, and the concentration of 13 cytokines were decreased after 4-hour reperfusion time. In 6-hour ischemia group, IL-2, IL-3, MCP-1 and TARC were increased, compared to normal control group, and IL-3 and MCP-1 were increased in 16-hour reperfusion time. To sum up, ischemia increased the pro-inflammatory cytokines compared to normal control group and in the 2-hour and 6-hour ischemia groups, IL-1α, IL-3, MCP-1 and TARC were increased until the late reperfusion time.

Lesión iatrogénica de la arteria iliaca común izquierda durante discectomía lumbar posterior / Iatrogenic injury to the left common iliac artery for posterior lumbar discectomy

Las lesiones vasculares durante la cirugía de hernia discal son infrecuentes, pero asociadas con una alta mortalidad dependiendo del vaso afectado, requiriendo de una sospecha diagnóstica y manejo temprano que puedan evitar el desenlace mortal. Dependiendo del nivel intervertebral intervenido las lesiones vasculares comprometerán en mayor o menor frecuencia los diferentes grandes vasos, siendo más frecuentes los traumas a la aorta en niveles altos y el compromiso de los vasos arteriales y venosos ilíacos comunes o sus ramificaciones en niveles inferiores, las estadísticas en cuanto a incidencia se creen son subestimadas debido a la infrecuencia con que son reportados estos casos. El objetivo de este artículo es exponer el caso de una lesión traumática intraoperatoria de la arteria ilíaca común izquierda durante un procedimiento de hemilaminectomia y microdisectomia L5 - S1, en la que la temprana sospecha de la lesión y contar con equipo quirúrgico altamente capacitado en la institución permitió realizar un manejo oportuno sin secuelas neurológicas o vasculares para el paciente. Compartimos este caso dado lo infrecuente de sus reportes en la literatura revisada, si tenemos en cuenta la frecuencia con el que neurocirujano o cirujano de columna realiza procedimientos para corrección de hernias discales, sin dimensionar en muchas ocasiones el alto riesgo de morbi-mortalidad derivadas de una complicación quirúrgica, que en nuestro caso de no haber contado con el equipo quirúrgico idóneo (anestesia, cuidados posoperatorios, cirujanos generales y vasculares), no se hubiera obtenido el buen resultado para el paciente.

Vascular injury during surgery herniated disc are rare, but associated with high mortality depending on the affected vessel, requiring a diagnostic suspicion and early management to avoid a fatal deselance. Depending on the level involved surgical, vascular lesions are more commonly involved trauma of the aorta at high levels and commitment of arterial and venous vessels common iliac, less frequently commits its branches at lower levels. Due to the low incidence of reporting of these cases statistics are underestimated. The aim of this article is to present the case of a traumatic injury intraoperative left common iliac artery for a microdiscectomy procedure hemilaminectomy and L5 - S1, where a timely management was conducted through early suspicion of injury and the surgical team highly trained in the institution. There were no neurological or vascular consequences for the patient. We share this case due to the rareness of their reports in the literature reviewed, if we consider the frequency with which neurosurgeon or spine surgeon performs procedures to correct herniated discs, not to mention the high risk of surgical morbidity and mortality. In our case you have not had the ideal surgical equipment (anesthesia, postoperative care, general and vascular surgeons) had not obtained the good result for the patient.

Subacute Course of Common Iliac Arterial Laceration in Lumbar Disc Surgery

Vascular injuries in lumbar disc surgery are serious complications which may be overlooked due to a broad range of clinical manifestations. It is important to be aware of the perioperative implications of this rare occurrence to lower mortality risk. A 20-yr-old man with a right L4-5 lumbar disc protrusion was operated on routinely under a surgical microscope. A bloody surgical field was noted temporarily during a discectomy along with a decreased blood pressure. After fluid resuscitation with an ephedrine injection, the bleeding soon stopped spontaneously and his vital signs were stabilized. Fifty hours after the operation, the patient showed signs of hypovolemic hypotension with abdominal distension. The right femoral artery pulsation was absent on palpation. An enhanced CT angiography revealed a retroperitoneal hematoma and obstruction of the left common iliac artery. An urgent laparotomy was done to repair the injured vessel by excision and interposition of a graft. The patient had an uneventful recovery.The subacute course of deterioration might have been due to intermittent blood leakage from the lacerated common iliac artery, which was sealed spontaneously. It is very important to pay close attention to post-surgical clinical manifestations to avoid a potentially fatal outcome in lumbar disc surgery.

Change of Common Iliac Artery after Abdominal Aortic Aneurysm Repair Using a Tube Graft / 대한혈관외과학회지

PURPOSE: It remains controversial whether to use a tube graft or a bifurcated graft during open abdominal aortic aneurysm (AAA) repair, due to the potential for progression or development of a common iliac artery (CIA) aneurysm. This study evaluated the fate of CIA after tubular AAA repair. METHODS: On a retrospective basis, we reviewed 61 patients who underwent open AAA repair with a tube graft, between March 2000 and December 2009. Fifty-seven patients were included in this study; we excluded 4 cases in which the patients died in-hospital. Of those enrolled, 24 patients underwent follow-up computed tomography at least 1-year after surgery. CIAs were categorized into 3 groups: normal (< or =12 mm), ectasia (range, 13 to 18 mm), and aneurysm (range, 19 to 25 mm). The incidence of CIA aneurysm rupture was investigated, and the expansion rate of CIA was calculated. RESULTS: Mean patient age was 64 years and 73% of patients were male. Preoperatively, 8 patients had 2 normal CIAs, 14 patients had one CIA aneurysm at least, 27 patients had one CIA ectasia, and 8 patients were unknown. There was a mean follow-up of 51 months; no deaths were caused by rupture of CIA aneurysm, and no patient underwent invasive treatment for a CIA aneurysm. The mean follow-up for 24 patients with 48 CIAs was 45 months. The mean expansion rate of CIA was 0.5 mm/y. CONCLUSION: AAA repair using a tube graft was a safe and durable procedure. However, a bifurcated graft should be considered when patients are young and there is the expectation of a long life expectancy is anticipated allowing for a CIA expansion rate of 0.5 mm/y.

Effectiveness of Embolization of Internal Iliac Artery during Endovascular Aneurysm Repair / 대한혈관외과학회지

PURPOSE: Embolization of the internal iliac artery (IIA) is frequently required during endovascular aneurysm repair (EVAR) because of a concurrent common iliac artery aneurysm, a short common iliac artery, or deployment of aortouni-iliac devices. This study was conducted to evaluate the effectiveness of IIA embolization during EVAR. METHODS: A retrospective study was performed in patients undergoing EVAR and IIA embolization from December 2005 to March 2011 from a prospectively registered database of patients with aneurysms. Patient clinical characteristics, procedures, and follow up data were collected and analyzed. RESULTS: Eighteen patients (33.3%) required IIA embolization among 54 EVARs. The mean age was 73.5 years, and 17 patients were male. Indications were a common iliac artery aneurysm (11/18), short iliac artery (3/18), thrombosed common iliac artery (1/18), arteriovenous malformation (1/18), and deployment of aortouniiliac artery devices (1/18). One mortality occurred in a patient with a ruptured abdominal aortic aneurysm. No type I endoleaks were observed. IIA embolization was achieved with conventional coils (7/18), a vascular plug (6/18), and detachable coils (5/18). After EVAR, there were two cases of ileus, a limb occlusion that required additional stenting in the external iliac artery, a type II endoleak, and two cases of buttock claudication. CONCLUSION: IIA embolization during EVAR is effective to prevent a type II endoleak with minor morbidities.

A Case of Membranous Glomerulonephritis Presenting with Right Common Iliac Artery Thrombosis as the Initial Sign / 대한내과학회지

Most patients with nephrotic syndrome visit the hospital because of edema due to hypoalbuminemia induced by severe proteinuria. However, rare cases have reported arterial thrombosis as the main problem complicating nephrotic syndrome. Arterial thrombosis combined with nephrotic syndrome is rarer than venous thrombosis, and it usually develops during treatment with steroids or diuretics. Arterial thrombosis is rarely diagnosed as the initial sign of nephrotic syndrome. We report the case of a 38-year-old-woman with membranous glomerulonephritis presenting with right common iliac artery thrombosis as the initial sign.

A Case of Intimal Sarcoma Arising in the Left Common Iliac Artery

Primary tumors of the great vessels are rare. Most encountered cases are sarcomas which most commonly develop in the aorta, pulmonary artery, and inferior vena cava. We experienced an intimal sarcoma arising in the left common iliac artery in a 68-year-old male, who suffered from claudication in his left lower extremity for a year and was diagnosed as arteriosclerosis obliterans, clinically. Bypass surgery was performed on the obstructive lesion. Grossly, the vascular lumen was filled with dark hemorrhagic materials. Microscopically, the lesion showed proliferation of anaplastic spindle cells with a marked nuclear atypia, arranged haphazardly. There were numerous mitotic figures. Foci of cholesterol clefts were also found in the intima. Immunohistochemically, the tumor cells were positive for vimentin, smooth muscle actin, and cytokeratin in certain areas. Stains for CD34, desmin, myosin heavy chain, caldesmon, and S-100 protein were negative. A pathologic diagnosis was made as intimal sarcoma with myofibroblastic differentiation.

Endovascular Treatment for Common Iliac Artery Injury Complicating Lumbar Disc Surgery : Limited Usefulness of Temporary Balloon Occlusion

Vascular injury during lumbar disc surgery is a rare but potentially life-threatening complication. It has been managed by open vascular surgical repair. With recent technologic advance, endovascular treatment became one of effective treatment modalities. We present a case of a 32-year-old woman who suffered with common iliac artery injury during lumbar disc surgery that was treated successfully by endovascular repair with temporary balloon occlusion and subsequent insertion of a covered stent. Temporary balloon occlusion for 1.5 hours could stop bleeding, but growing pseudoaneurysm was identified at the injury site during the following 13 days. It seems that the temporary balloon occlusion can stall bleeding from arterial injury for considerable time duration, but cannot be a single treatment modality and requires subsequent insertion of a covered stent.

Thrombosis of Left Common Iliac Artery Following Anterior Lumbar Interbody Fusion: Case Report and Review of Literatures

We report on a case of thrombosis of the left common iliac artery following anterior lumbar interbody fusion (ALIF) of L4-5 in a 79-year-old man with no previous medical problems, including peripheral vascular disease. After completing the ALIF procedure, the surgeon could not feel the pulsation of the left dorsalis pedis artery, and the oxygen saturation (SaO2) had fallen below 90% from pulse oxymetry on the left great toe. Thrombectomy was successfully performed after confirming the thrombus in the left common iliac artery using Computed Tomography (CT) angiography. Thrombosis of the common iliac artery is very rare following ALIF. However, delayed diagnosis can lead to disastrous outcome. Although elderly patients have no cardio-vascular disease or vessel calcification in pre-op evaluation, the possibility of a complication involving L4-5 should be considered.

Isolated Aneurysm of the Left Common Iliac Artery that was Secondary to Medial Degeneration

Isolated aneurysm of the common iliac artery that is secondary to medial degeneration (MD) is a very rare clinical entity. MD is an important histological abnormality that is commonly seen in the annuloaortic ectasia with Marfan syndrome. This abnormality is also observed in congenital aortic disease, atherosclerosis, and aging. This aortic disease develops as the consequences of disruption of the medial elastic layers in association with loss of vascular smooth muscle cells and the accumulation of proteoglycans. An iliac aneurysm greater than 3 cm in diameter should be treated. The treatment options include open surgical replacement with prosthetic graft or endovascular stent grafting. We experienced one case of the isolated common iliac artery aneurysm in a 60 year-old female patient. Her chief complaint was a pulsatile painful mass in the left lower quadrant of the abdomen that she had suffered with for 5 days. She was treated by performing aorto-left external iliac artery bypass with a Dacron graft (10 mm in diameter). The result was excellent. We report here on a case of a isolated common iliac artery aneurysm that was caused by MD, and we include a review of the relevant literature.

A Case of Nephrotic Syndrome Complicated by the Thrombosis of Common Iliac Artery and Coronary Artery of Heart / 대한신장학회잡지

Thrombosis is one of the important complications of nephrotic syndrome. Still, the mechanism of thrombosis of nephrotic syndrome is under debate, but the presence of hypercoagulable state in nephrotic syndrome is regarded as the principal contributing factor to that. Venous thrombosis in nephrotic syndrome has been increasingly reported, but arterial thrombosis is relatively rare and has been reported mainly in nephrotic children. Authors experienced a 35-year old male patient with frequently relapsing nephrotic syndrome of focal segmental glomerulosclerosis, who complained sudden onset of claudication, cold sensation, numbness and cyanosis of right lower extremity. A diagnosis of thrombosis in right common iliac artery and thromboses in septal and distal branch of left anterior descending coronary artery was made by arterial angiography. The patient fully recovered after emergent thrombectomy and anticoagulation therapy.

A Case of Transluminal Stent-Graft for Right Common Iliac Artery Aneurysm with Behcet's syndrome / 대한류마티스학회지

Behcet's disease is characterized by recurrent orogenital ulcers and ocular and cutaneous inflammatory lesions. It is a multisystem disorder affecting the skin, mucous membrane, eyes, joints, CNS and blood vessels. The vascular involvements consist of thrombophlebitis, arterial occlusion and arterial aneurysm. Rupture of large artery aneurysm is the leading cause of death in patients with Behcet's disease and surgical treatment is necessary. But, surgical treatment is often difficult and may lead to formation of further false aneurysms at the site of vascular anastomosis. Endovascular stent-graft placement emerged as an alternative treatment that is less invasive with a lower risk. We report a case of the aneurysm of right common iliac artery associated with Behcet's disease. Percutaneous stent-graft placement was attempted and successfully controlled aneurysmal manifestations.

Common iliac artery in Thais.

From the dissection of 327 adult Thai cadavers the beginning, the sites of the ending and the length of the common iliac artery were recorded. The common three out of seven sites of the beginning which were anterior to the following structures respectively were : the body of the 4th lumbar vertebra (45.6%), the intervertebral disc between the 4th and the 5th lumbar vertebrae (28.7%) and the body of the 5th lumbar vertebra (21.7%). From seven sites of ending, the first three common were anterior to the following structures respectively: the ala of the sacrum (44.0%), the body of the 5th lumbar vertebra (27.1%), and the intervertebral disc between the 5th lumbar vertebra and the sacrum (17.0%). The average length of the common iliac artery was 4.7 cm.
