RESUMEN
Objetivo: Presentar un caso infrecuente de aneurisma gigante de arteria iliaca interna roto. Caso clínico: Varón de 68 años de edad con antecedentes de hipertensión arterial crónica, dislipidemia, cardiopatía valvular, cor pulmonale con hipertensión pulmonar moderada, portador de marcapasos definitivo, obesidad y alergia a la plata. Ingresa de urgencia por dolor brusco en fosa iliaca izquierda, irradiado periumbilicalmente sin cortejo vegetativo. En el TC abdominal se objetiva la presencia de un aneurisma gigante de la arteria hipogástrica izquierda con diámetro de 6,8 cm y signos de rotura. Se realiza de forma urgente cirugía endovascular mediante implante de prótesis Endurant® y embolización de arterias glúteas con Coils Interlock®. Control al mes y a los 6 meses sin endofugas ni crecimiento del saco. Discusión: El tratamiento de elección de los aneurismas iliacos sigue siendo la cirugía, de forma electiva cuando el diámetro de la arteria es mayor de 3 cm y urgente cuando debutan con rotura. La terapia endovascular es una alternativa segura y eficaz a la cirugía convencional, con resultados satisfactorios a corto y medio plazo.
Aim: To present an infrequent broken giant Iliac artery aneurysms. Case report: In the current study, we report a case of a 68-year-old male patient with chronic high blood pressure, cholesterol, valvular heart disease, cor pulmonale, pacemaker, obesity and silver allergic. He presented sudden onset of abdominal pain. Computed tomography (CT) revealed a large ruptured left hypogastric aneurysm (diameter of 6.8 cm). Hypogastric aneurysm was repaired by an endovascular graft repair: Endurant® endogratf and coils embolization of gluteal arteries (Interlock®). The patient had a satisfactory clinical progression and recovery. At one and six months after the operation TC revealed not Type II endoleaks. Discussion: Isolated aneurysms of the iliac arteries are rare. Surgical treatment is recommended for iliac artery aneurysms larger than 3 cm. Endovascular repair is an attractive method to repair isolated iliac artery aneurysms with lower morbidity and mortality rates than open surgery.

Tumors in the pelvic cavity frequently involve the iliac vessels. Common and external iliac arteries should be reconstructed to restore the flow to the lower extremity if the tumor directly invades these arteries. We report herein a 58-year-old female patient with a 10x11 cm, recurred uterine leiomyosarcoma. We performed en bloc resection of the tumor mass including the sigmoid colon, left ureter and 5 cm of the left external iliac artery. After complete resection, restoration of arterial flow to the lower extremity was made with a novel strategy of hypogastric artery transposition. There was no evidence of tumor recurrence or vascular insufficiency at 12 months after surgery.

The purpose of this case report was to discuss the efficacy of The Amplatzer Vascular Plug (AVP) in endovascular aneurysm repair (EVAR) for ruptured aortoiliac aneurysm. A 73-year-old man was referred to our institution with a diagnosis of ruptured abdominal aortic aneurysm (rAAA) by CT scan. The CT scan showed an rAAA of 70 mm (Fitzgerald classification 3) and a right common iliac aneurysm of 30 mm. The patient was immediately transferred from the ER to the OR and treated with EVAR in combination with occlusion of the right internal iliac artery (IIA) using AVP. The total procedural time was 138 min. The patient recovered uneventfully after the operation with an ICU stay of 2 days and was discharged 9 days after the onset. EVAR has been recognized as a therapeutic option for rAAA in Japan. However, it is not yet been generally adopted as a first-line therapy for rAAA accompanied with iliac aneurysm because of the necessity to occlude IIA. The conventional method with coils to induce thrombosis of IIA is unsuitable for patients in a critical situation for the time required and the difficulty in precise placement. AVP is a nitinol-based self-expanding cylindrical device that is used for arterial embolization. AVP allows assured embolization of IIA in a shorter procedural time, which is essential in an urgent situation. Although AVP is still under post-market surveillance in Japan and only available in limited institutions, the usage of AVP should be considered as an adjunctive procedure in EVAR for rAAA and may expand the limits of endovascular treatment for rAAA.
RESUMEN
A difficult anatomy is the major challenge to overcome with abdominal aortic aneurysm endografting. Bilateral iliac aneurysm preventing an appropriate distal landing zone for an endograft is a common condition and can be managed by: a) Increasing the diameter of the endograft, with limitations in available sizes; b) bilateral hypogastric embolization, accepting an increased morbidity; c) combining a surgical hypogastric revascularization by retroperitonel approach or d) retrograde revascularization from the ipsilateral external iliac artery using an endograft. Recently, branched endografts have been designed to revascularize the hypo gastric artery. Their deployment is complex but allows antegrade and stable flow. We report a 57 year-old male, at high risk for an open procedure, who presented with a small aortic aneurysm, bilateral iliac and left hypogastric aneurysms. A right bifurcated iliac endograft was deployed, associated with left hypogastric aneurysm embolization and aortic endografting. The patient recovered event free, patency of the endograft and absence of endoleak was demonstrated on a CT scan. He presented minor left buttock claudication, sexual function was preserved. This new technique allows safe endovascular treatment of patients with bilateral iliac aneurysm, allowing preservation of pelvic perfusion and avoiding the risk of an open procedure in a high risk patient.
Una anatomía desfavorable es un obstáculo a vencer con el tratamiento endovascular del aneurisma aorto-ilíaco. La presencia de aneurisma ilíaco bilateral es frecuente y amenaza la adecuada fijación distal de una endoprótesis. Esta condición puede ser manejada: a) aumentando el diámetro del dispositivo a nivel ilíaco, con limitaciones en las medidas disponibles; b) embolización hipogástrica bilateral, aceptando una morbimortalidad mayor; c) combinando un abordaje quirúrgico retroperitoneal para revascularizar una arteria hipogástrica, aumentando el impacto del procedimiento; d) mediante revascularización retrógrada unilateral desde la arteria ilíaca externa ipsilateral con otra endoprótesis. Recientemente se ha descrito el uso de endoprótesis ramificadas, que requieren un despliegue complejo, pero permiten revascularizar una o ambas arterias hipogástricas en forma anterógrada y estable. Reportamos el caso de un paciente de sexo masculino y 57 años, de alto riesgo para cirugía convencional, portador de un aneurisma pequeño de aorta abdominal y aneurismas ilíaco común bilateral e hipogástrico izquierdo. Fue tratado mediante despliegue de una endoprótesis bifurcada ilíaca, revascularizando la arteria hipogástrica derecha y embolizando la izquierda aneurismática, asociado a implante de una endoprótesis aórtica convencional, también bifurcada. El paciente evoluciona sin complicaciones, con claudicación glútea izquierda leve en disminución y preservación de su función sexual. Una tomografía axial computada demuestra exclusión efectiva de sus aneurismas. Esta nueva técnica permite tratar de manera segura a pacientes portadores de aneurisma ilíaco bilateral en forma endo-vascular, manteniendo perfusión de la circulación pelviana y disminuyendo el impacto de un procedimiento convencional en pacientes de alto riesgo.

Abnormal attachment of the placenta (Placenta accreta, increta, and percreta) is an uncommon but potentially lethal cause of maternal mortality from massive postpartum hemorrhage. A 33-yr-old woman, who had been diagnosed with a placenta previa, was referred at 30 weeks gestation. On ultrasound, a complete type of placenta previa and multiple intraplacental lacunae, suggestive of placenta accreta, were noted. For further evaluation of the placenta, pelvis MRI was performed and revealed findings suspicious of a placenta increta. An elective cesarean delivery and subsequent hysterectomy were planned for the patient at 38 weeks gestation. On the day of delivery, endovascular catheters for balloon occlusion were placed within the hypogastric arteries, prior to the cesarean section. In the operating room, immediately after the delivery of the baby, bilateral hypogastric arteries were occluded by inflation of the balloons in the catheters previously placed within. With the placenta retained within the uterus, a total hysterectomy was performed in the usual fashion. The occluding balloons were deflated after closure of the vaginal cuff with hemostasis. The patient had stable vital signs and normal laboratory findings during the recovery period; she was discharged six days after delivery without complications. The final pathology confirmed a placenta increta.

Objective To summarize our experiences of management for hypogastric artery in endovascular repair(EVR) of infrarenal abdominal aortic aneurysm(IAAA).Methods From July,1997 to March,2007,62 cases of IAAAs required special management of the internal iliac artery(IIA) during the EVR.Among them,57 cases were type C AAA who included 35 cases of unilateral common iliac artery(CIA) bifurcations and 22 cases of bilateral iliac bifurcations.The remaining 5 cases involved superior iliac bifurcations.Various techniques including simple coverage by stent-graft,embolization of the IIA trunk combined with stent-graft covering,reconstruction of the IIA and combination of the above techniques were applied according to the different conditions of the IIA involved.Results None of the 62 patients required conversion to surgical repair.Immediate post operational angiography demonstrated type Ⅰ endoleak in 6 cases(9.7%).Claudication due to gluteus ischemia occurred in 5 cases(8.1%),leg numbness in 1 case(1.6%),and severe constipation in 1 case(1.6%),but no buttock and colorectal necrosis was recorded.Conclusion It is important to preserve one of the hypogastric arteries and avoid occlusion of both hypogastric arteries in EVR of IAAA.
RESUMEN
Objective To evaluate the effects of hypogastric artery ligation to treat massive hemorrhage in pelvic fractures with abdominal organ injuries. Methods The pelvic fractures of 16 patients were classified as Tile B type in 10 cases and C type in 6. Among them there were 6 open fractures and 20 sites of abdominal visceral injuries. The capacity of retroperitoneal hematoma, which was ruptured in 6 cases, ranged from 800 ~2 500ml with 1 400ml on average. The bleeding volume in the survivals was 1 500~5 800ml with 2 600ml on average. Ligation of bilateral hypogastric artery was carried out in all patients with intra abdominal injuries within 6h. Of them, skeletal traction was used in 7 cases while pelvic external fixation in 5 cases. Results One death occured dut to consumptive coagulopathy with hematorrhea. Of the 15 survivals, bleeding was controlled in 8 cases, decreased in 5 and uncontrolled in 2. The effective rate was 81.3%(13/16) and the survival rate 93.8%(15/16). Conclusion When emergency celiotomy is performed for abdominal injuries, a rational application of hypogastric artery ligation can play a positive role in control of pelvic hematorrhea.
RESUMEN
PURPOSE: We assessed the long term efficacy and complications of angiographic embolization of hypogastric arteries in treating the intractable bladder hemorrhage induced by radiation. MATERIALS AND METHODS: From January 1990 to December 1997, a total of 43 patients with radiation induced hemorrhagic cystitis were evaluated. Of 43 patients, 5 patients were treated by bilateral selective angiographic embolization of the anterior branches of the hypogastric arteries. The embolic material used in all patients was gelfoam. RESULTS: Five patients with intractable bladder hemorrhage were treated by bilateral selective embolization of the anterior branches of the hypogastric arteries by gelfoam and successful in completely stopping or considerably decreasing intractable bladder hemorrhage in all patients. The average number of treatments was 1.6(range 1 to 2). There was no significant sequelae ocurred as a consequence of simultaneous bilateral occlusion of the hypogastric arteries. CONCLUSIONS: Radiation induced hemorrhagic cystitis that do not respond to irrigations with chemical cauterizing agents or transurethral fulguration of bleeding vessels can be successfully treated with bilateral selective angiographic embolization of the anterior branches of the hypogastric arteries.
