EVAR with Aortic Placement of a Single JOTEC E-iliac Stent-graft System in a Patient with Poliomyelitis Aortoiliac Deformities.

Small-sized vessels can represent a contraindication to standard endovascular aortic repair (EVAR), and more specifically, aortoiliac deformities resulting from poliomyelitis may add an adjunctive challenge for total endovascular repair. Herein we report a case of a 62-year-old man with a 55 mm abdominal aortic aneurysm (AAA) and a history of poliomyelitis. More specifically, a computed tomography angiogram (CTA) showed a very narrow infrarenal aortic neck, measuring 13 mm in maximum diameter, and severely atrophic external iliac and common femoral arteries. A total endovascular repair was planned and realized with a single aortic JOTEC iliac branch and contralateral VBX placement. All prosthetic materials were delivered from the nonatrophic side. At the 1-year CTA, the aneurysm was successfully excluded and both iliofemoral axes were patent.

A patient with lower gastrointestinal bleeding: common history, very uncommon cause, minimally invasive treatment.

An 81-year-old patient with significant cardiac comorbidities, a history of sigmoid resection 6 years ago, and iliac bypass surgery 19 years ago presented with mild hematochezia for the previous 3 days. While hemodynamically stable at first, he developed massive bleeding during preparation for colonoscopy and underwent a short course of cardiopulmonary resuscitation. Colonoscopy revealed no active bleeding but a protuberance of the colonic wall and a coagulation clot. In ultrasonography immediately after endoscopy, a large aneurysm was diagnosed and diagnosis of an iliaco-colonic fistula was assumed. CT scan demonstrated a large pseudoaneurysm of the distal anastomosis after iliaco-iliac bypass. With endovascular treatment, the original lumen of the iliac artery could be recanalized, and 2 covered stents were placed to cover both anastomosis of the prosthetic bypass leading to a complete shutdown of bypass perfusion. A double-barreled transversostoma was established to minimize contamination of the aneurysmal sac. Seven months after these procedures, the patient is well and free of infection.Though aorto- or iliaco-colonic fistula after aortic or iliac surgery are very rare, endoscopists should be aware of their possibility. A high index of clinical suspicion in patients with prior abdominal vascular bypass surgery should prompt rapid imaging studies, possibly before endoscopy. In critically ill patients, endovascular treatment may be a suitable alternative and result in a favorable outcome.

[Hybrid intervention for an atherosclerotic lesion of arteries of the iliofemoral segment]. / Gibridnoe vmeshatel'stvo pri ateroskleroticheskom porazhenii arterii podvzdoshno-bedrennogo segmenta.

The article describes a clinical case report regarding a successfully performed hybrid intervention in a patient presenting with critical ischaemia of a lower limb and an atherosclerotic lesion of arteries of the iliofemoral segment. Endovascular reconstruction in an isolated manner turned out to be impossible for both technical and anatomical reasons, whereas open reconstruction required two surgical accesses, an extended scope of the operation, and the use of a synthetic graft. Using a hybrid approach favourably contributed to adequate restoration of blood flow in the ischaemized limb, a decrease in the traumatic nature of the intervention, and also ensured angiographic control over the state of the operated arterial segment.

Spiral saphenous vein graft for major pelvic vessel reconstruction during exenteration surgery.

This article describes a great saphenous vein spiral graft technique for reconstruction of iliac vessels after en bloc resection during pelvic exenteration. Use of different size syringes as a scaffold allows the surgeon to construct autologous vascular interposition conduits of variable diameter to match the luminal size of the vessel requiring reconstruction. Autologous vascular grafts are preferred in exenteration surgery in which the operative field is commonly contaminated by concomitant bowel resection, which carries an increased risk of graft infection.

Technical modification for laparoscopic donor nephrectomy to minimize testicular pain: a complication with significant morbidity.

The laparoscopic approach to donor nephrectomy is becoming increasingly common. While it is felt that the recovery from laparoscopic nephrectomy is quicker and less painful, a number of complications have been reported. A rarely reported on complication in the literature with significant morbidity is ipsilateral orchalgia. From 1998 to 2008, 257 hand-assisted laparoscopic donor nephrectomies were performed at our institution. Eight of 129 (6.2%) men complained of de novo ipsilateral orchalgia postoperatively. The average duration of pain was 402 days. Patients reported significant morbidity related to this complication. None, however, required further treatment. Three patients reported that they would reconsider organ donation as a result of testicular pain. Our technique originally included dissection and ligation of the gonadal vein en bloc with the ureter at the level of the left common iliac artery. Since recognizing this complication, we have adopted a gonadal vein sparing approach so as not to disturb the vessel below its point of ligation at the renal vein. To date, 50 patients have undergone the modified technique without experiencing orchalgia. In conclusion, ipsilateral testicular pan is a relatively frequent complication of laparoscopic donor nephrectomy and may be a source of significant morbidity. Using a modified surgical technique, this complication can be reduced or eradicated.

Acute thrombosis of external iliac artery secondary to endofibrosis.

Iliac endofibrosis is a rare condition caused by chronic wall stress and a subsequent progressive fibrosis that usually affects the external iliac artery. It can present with intermittent claudication and is most commonly found in young athletes without significant risk factors for peripheral arterial disease. We present a case of acute thrombosis of the external iliac artery secondary to endofibrosis in a 38-year-old cyclist and describe the treatment options. For symptomatic patients and in case of long arterial occlusion, the treatment of choice is the surgical resection with autologous vein interposition.

A case of spontaneous rupture of nonaneurysmal left iliac artery due to penetrating atherosclerotic ulcer.

We report on a patient with spontaneous rupture of a nonaneurysmal left common iliac artery in whom hemorrhagic shock developed. A 64-year-old woman presented with hemodynamic collapse accompanied by sudden abdominal pain. She was transported to the emergency department. Angiography showed a penetrating atherosclerotic ulcer in the left common iliac artery. Emergency surgery was performed with graft replacement (14 x 7 mm woven Dacron graft). Severe calcification was observed in the left common iliac artery, and an ulcer of the iliac artery was confirmed as the source of hemorrhage. The postoperative course was uneventful, and the patient was discharged on postoperative day 14. We conclude that rupture may occur in patients with severe atherosclerotic change, even in the absence of aneurysm.

Chimney-Patch Arterial Graft in Kidney or Pancreas Transplantation for Recipients with Heavily Calcified Iliac Arteries.

Iliac artery calcification is a common phenomenon complicating renal transplantation, particularly in those with diabetes. The potential for vascular clamp injury can threaten the renal allograft, ipsilateral lower extremity, or both. Utilization of internal balloon occlusion can allow for placement of a "Chimney Patch" graft, fashioned from a deceased donor artery, to the calcified vessel, eliminating the risk of clamp injury and minimizing warm ischemic time. We present a series of 6 patients transplanted with internal balloon occlusion with successful renal and pancreatic allograft function and no ipsilateral vascular complications. Internal balloon occlusion is a safe and effective adjunct for renal or pancreas transplant to prevent clamp injury with no adverse effect on allograft function.

A Rare Case of Superior Gluteal Artery Pseudo Aneurysm after Blunt Trauma.

Prevailing over in rotationally unstable pelvic fractures, acetabular fractures or hip dislocations, superior gluteal artery pseudo aneurysm imperceptibly could be found after blunt force trauma of the pelvic region. We present a case of superior gluteal artery pseudo aneurysm after blunt force trauma that became gradually symptomatic in two months following the prime malevolence. Non-resolving gluteal hematoma presented two months after the incident, disregarding standard treatment methods led the diagnosis to plausible entity of pseudo aneurysm. Standard protocol was followed. CT angiography was indicated and it confirmed the suspected diagnosis. Upon indication a treatment plan was established with correspondent angioembolization of the pathologic substrate. Pseudo aneurism of the superior gluteal artery should be considered as differential diagnosis for unexplained hematomas in the posterior pelvic region following a trauma regardless of its nature.

External iliac artery thrombosis after open reduction of an acetabular fracture: a case report.

Major arterial injury from open reduction and internal fixation of an acetabular fracture through an ilioinguinal approach is rare. Detection of a major intraoperative arterial injury is simple. Detection of a more occult injury leading to thrombosis is not. We report the third known case of thrombosis of the external iliac artery following open reduction and internal fixation of an anterior column fracture. This case is of particular interest because it highlights the ability of young patients to compensate for major vessel occlusion and still maintain a well-perfused foot. Heightened awareness of subtle side-to-side differences in pulses postoperatively may reveal that occult injury is a more common occurrence than previously appreciated.

Percutaneous extraction of a short, 0.038-inch guide wire retained in the right common iliac artery.

Percutaneous extraction of intravascular foreign bodies with the help of specifically designed devices is the standard method of treatment and should be attempted in appropriate cases before any surgical approach. The majority of retrieved materials are catheter fragments localized in the superior vena cava, right side of the heart, or pulmonary artery. During diagnostic coronary angiography of a 65-year-old man, a short, 0.038-inch guide wire was identified in the right common iliac artery. It was erroneously left there during arterial monitoring performed at another center. The guide wire was successfully removed percutaneously using a combination of "wire-balloon" technique without any available specifically designed device.

Intermittent claudication caused by a hip joint ganglion.

A case report of a patient with unusual compressive syndrome is reported herein. A 27-year-old woman was referred to our hospital due to intermittent claudication in the left thigh and calf which gradually developed over the last five months. Angiography showed an atypical short occlusion of the external iliac artery. Only surgical revision made an exact diagnosis. The formation compressing the artery was a ganglion that originated from the hip joint and adhered to the artery. Resection of the ganglion was carried out. The adjacent segment of the artery was removed and replaced by end-to-end venous graft using vena saphena magna. From the operation until present (30 months) the patient remains symptom-free. To our knowledge a hip joint ganglion compressing the artery and causing symptoms of peripheral arterial disease has not been previously reported in medical literature.

Palliative Endovascular Techniques for Management of Peripheral Vascular Blowout Syndrome in End-Stage Malignancies.

Vascular blowout syndrome (VBOS) secondary to neoplastic erosion is a dreadful complication of advanced stage malignancies that can compromise quality of life and overall prognosis in a fragile patient population. Endovascular therapy can offer minimally invasive, life-saving maneuvers both acutely and prophylactically. Four patients with end-stage malignancies eroding into various peripheral vascular beds with impending, threatened, and acute VBOS underwent successful endovascular management. Technical success was achieved in all patients with no perioperative morbidity or mortality. In all patients, endovascular intervention controlled life-threatening hemorrhage and facilitated adjunctive therapeutic modalities such as surgical tumor debulking and/or chemoradiation. In conclusion, our small case series demonstrates that endovascular therapy can offer safe and effective palliation of peripheral VBOS secondary to neoplastic erosion.

[A 26-year-old cyclist with intermittent claudication]. / Claudicatio intermittens bij een 26-jarige wielrenner.

A 26-year-old male amateur cyclist, with no risk factors for vascular disease or previous trauma, presented with left-calf claudication. Physical and additional examination revealed an occlusion of the external iliac artery. During the operation, the cause was found to be an endofibrotic lesion of the external iliac artery, probably due to mechanical trauma as a result of the non-physiological aerodynamic position held on the bicycle during many hours of training. An endarterectomy was performed and the tendon of the psoas-minor muscle was cut because of its strong impression on the psoas-major muscle, which resulted in kinking of the external iliac artery. There followed two episodes of re-occlusion which were treated with a venous interposition graft and a dacron interposition graft, respectively. Thereafter the patient was able to train without pain. Intermittent claudication of the legs in young athletes should not be underestimated; occlusive vascular disease caused by arterial endofibrosis should be considered.

Delayed postpartum abdominal bleeding caused by a spontaneous ruptured branch of the internal iliac artery and successfully treated by arterial embolisation.

A 34-year-old gravida 2 para 1 had an uneventful second pregnancy and successful vaginal birth after caesarean section. She was readmitted on the third day postpartum with severe abdominal pain coinciding with lactation. On admission, her vital signs were stable and was expectantly managed. After an unexpected drop in haemoglobin level, a CT scan was ordered, showing a haemoperitoneum. Laparoscopy was performed and 2.5L of blood was evacuated from the peritoneal cavity, no source of the bleeding could be identified. At the intensive care unit the patient's vital signs deteriorated and her haemoglobin level dropped to 2.2 mmol/L. The patient was stabilised and instead of a laparotomy to locate the bleeding, an arterial CT and angiography were performed. This revealed the presence of a blush from a pseudoaneurysm rising from a branch of the internal iliac artery. The artery was successfully occluded by embolisation.

Endovascular stent grafts for aneurysmal and occlusive vascular disease.

BACKGROUND: This report details our initial experience with two types of endovascular grafts- one for the treatment of infrarenal abdominal aortic aneurysms and the other for the treatment of iliac artery occlusive disease. METHODS: An abdominal aortic aneurysm was repaired in 34 patients using 3 different types of Ancure endografts (Menlo Park, California). Control patients (n = 9) had a standard aneurysm repair. Patients with chronic lower extremity ischemia (n = 7) secondary to iliac artery occlusive disease were treated with a Hemobahn endograft (W. L. Gore & Associates, Flagstaff, Arizona). RESULTS: Ancure graft deployment was achieved in 33 of 34 (97.1%) patients. Perioperative mortality for the Ancure and control group patients was 2.9% and 0%, respectively. Periprosthetic leaks were identified within 48 hours of deployment in 6 (18.2%) Ancure graft patients. All but 2 of the leaks resolved on serial follow-up. Additional endovascular procedures were required in 11 (32.4%) Ancure graft patients at the initial procedure or during follow-up to correct graft or arterial stenoses. Patients treated with an endovascular graft had significantly less blood loss and shorter hospital stays than control group patients. For Hemobahn patients, the technical success for graft deployment was 100%. There were no perioperative deaths. The ankle/brachial index increased from a mean of 0.52 preoperatively to 0.86 postoperatively (P = 0.004). One patient required a Wallstent in follow-up to correct a graft wrinkle. Angiography at 6 months demonstrated mild intimal hyperplasia in the stent graft in 5 of 6 patients. CONCLUSIONS: These early results support the potential for endovascular grafts in the treatment of aneurysmal and occlusive vascular disease. Further modifications in the devices and deployment techniques are necessary to reduce the incidence of periprosthetic leaks, graft limb stenoses, and intimal hyperplasia.
