BACKGROUND AND OBJECTIVES: Thoracic endovascular aortic repair exhibits limitations in cases where the aortic pathology involves the aortic arch. We had already developed a fenestrated aortic stent graft (FASG) with a preloaded catheter for aortic pathology involving the aortic arch. FASG was suitable for elective cases. MATERIALS AND METHODS: An aortic arch stent graft with a window-shaped fenestration (FASG-W) for supra-aortic arch vessels is suitable for emergent cases. This study aims to test a FASG-W for supra-aortic arch vessels and to perform a preclinical study in swine to evaluate the safety and efficacy of this device. Six FASG-Ws with 1 preloaded catheter were advanced through the iliac artery in 6 swine. The presence of endoleak and the patency and deformity of the grafts were examined with computed tomography (CT) at 4 weeks postoperatively. A postmortem examination was performed at 8 weeks. The mean procedure time for FASG-W was 27.15±4.02 minutes. The mean time for the selection of the right carotid artery was 5.72±0.72 minutes. RESULTS: Major adverse events were not observed in any of the 6 pigs who survived for 8 weeks. For the FASG-W, no endoleaks, no disconnection, and no occlusion of the stent grafts were observed in the CT findings or the postmortem gross findings. CONCLUSION: The procedure with the FASG-W was able to be performed safely in a relatively short procedure time and involved an easy technique. The FASG-W was found to be safe and convenient for use in this preclinical study of swine.

OBJECTIVE: A causal relationship between removal of circumflex iliac nodes distal to the external iliac nodes (CINDEIN) and lower leg edema has been recently suggested. The aim of this study was to elucidate the incidence of CINDEIN metastasis in cervical cancer. METHODS: A retrospective chart review was carried out for 531 patients with cervical cancer who underwent lymph node dissection between 1993 and 2014. CINDEIN metastasis was pathologically identified by microscopic investigation. After 2007, sentinel lymph node biopsy was performed selectively in patients with non-bulky cervical cancer. The sentinel node was identified using 99mTc-phytate and by scanning the pelvic cavity with a γ probe. RESULTS: Two hundred and ninety-seven patients (55.9%) underwent CINDEIN dissection and 234 (44.1%) did not. The percentage of International Federation of Gynecology and Obstetrics stage IIb to IV (42.4% vs. 23.5%, p<0.001) was significantly higher in patients who underwent CINDEIN dissection than those who did not. CINDEIN metastasis was identified in 1.9% overall and in 3.4% of patients who underwent CINDEIN dissection. For patients with stage Ia to IIa disease, CINDEIN metastasis was identified in 0.6% overall and in 1.2% of patients who underwent CINDEIN dissection. Of 115 patients with sentinel node mapping, only one (0.9%) had CINDEIN detected as a sentinel node. In this case, the other three lymph nodes were concurrently detected as sentinel lymph nodes. CONCLUSION: CINDEIN dissection can be eliminated in patients with stage Ia to IIa disease. CINDEIN might not be regional lymph nodes in cervical cancer.

Standard endovascular repair of iliac/aortoiliac pathologies can lead to complications, such as buttock claudication, colon ischemia and erectile dysfunction. Branch grafts have been developed but require at least 6 weeks for customization and are not currently available in China; they are also quite expensive. To our knowledge, modified fenestrated stent grafts (MFSGs) are a safe and effective alternative for treating patients with juxtarenal aneurysms. Most MFSGs are used for the preservation of renal and left subclavian arteries. Few cases of MFSGs have been reported in the treatment of iliac pathologies. The use of an MFSG is decided on a case-by-case basis. This report presents our first clinical use of an MFSG for preservation of the internal iliac artery.

PURPOSE: Appropriate animal models of atherosclerotic plaque are crucial to investigating the pathophysiology of atherosclerosis, as well as for the evaluation of the efficacy and safety of vascular devices. We aimed to develop a novel animal model that would be suitable for the study of advanced atherosclerotic lesions in vivo. MATERIALS AND METHODS: Atherosclerotic plaque was induced in 24 iliac arteries from 12 rabbits by combining a high cholesterol diet, endothelial denudation, and injection into the vessel wall with either saline (n=5), olive oil (n=6), or inflammatory proteins [n=13, high-mobility group protein B1 (HMGB1) n=8 and tumor necrosis factor (TNF)-α n=5] using a Cricket™ Micro-infusion catheter. Optical coherence tomography (OCT) was performed to detect plaque characteristics after 4 weeks, and all tissues were harvested for histological evaluation. RESULTS: Advanced plaque was more frequently observed in the group injected with inflammatory proteins. Macrophage infiltration was present to a higher degree in the HMGB1 and TNF-α groups, compared to the oil or saline group (82.1±5.1% and 94.6±2.2% compared to 49.6±14.0% and 46.5±9.6%, p-value<0.001), using RAM11 antibody staining. On OCT, lipid rich plaques were more frequently detected in the inflammatory protein group [saline group: 2/5 (40%), oil group: 3/5 (50%), HMGB1 group: 6/8 (75%), and TNF-α group: 5/5 (100%)]. CONCLUSION: These data indicate that this rabbit model of atherosclerotic lesion formation via direct injection of pro-inflammatory proteins into the vessel wall is useful for in vivo studies investigating atherosclerosis.

Since the introduction of pancreas transplantation more than 40 years ago, surgical techniques and immunosuppressive regiments have improved and both have contributed to increase the number and success rate of this procedure. However, graft survival corresponds to early diagnosis of organ-related complications. Thus, knowledge of the transplantation procedure and postoperative image anatomy are basic requirements for radiologists. In this article, we demonstrate the imaging spectrum of pancreas transplantation with enteric exocrine drainage.

OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.
METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.
RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.
CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.

We report a case of erectile dysfunction caused by external iliac artery occlusion, associated with pelvic steal syndrome; bilateral internal iliac arteries were patent. The patient stated that he had experienced erectile dysfunction at similar times along with claudication, but he did not mention it before angiography. He expressed that the erectile dysfunction did not last long and that he felt completely okay after the interventional procedure, in addition to his claudication. Successful treatment of the occlusion, by percutaneous transluminal angioplasty and stent implantation, helped resolve erectile dysfunction completely and treat the steal syndrome.

Spontaneous retroperitoneal hemorrhage is one of the most serious and often lethal complications of anticoagulation therapy. The clinical symptoms vary from femoral neuropathy to abdominal compartment syndrome or fatal hypovolemic shock. Of these symptoms, abdominal compartment syndrome is the most serious of all, because it leads to anuria, worsening of renal failure, a decrease in cardiac output, respiratory failure, and intestinal ischemia. We report a case of a spontaneous retroperitoneal hemorrhage in a 48-year-old female who had been receiving warfarin and aspirin for her artificial aortic valve. She presented with a sudden onset of lower abdominal pain, dizziness and a palpable abdominal mass after prolonged straining to defecate. Computed tomography demonstrated a huge retroperitoneal hematoma and active bleeding from the right internal iliac artery. After achieving successful bleeding control with transcatheter arterial embolization, surgical decompression of the hematoma was performed for management of the femoral neuropathy and the abdominal compartment syndrome. She recovered without any complications. We suggest that initial hemostasis by transcatheter arterial embolization followed by surgical decompression of hematoma is a safe, effective treatment method for a spontaneous retroperitoneal hemorrhage complicated with intractable pain, femoral neuropathy, or abdominal compartment syndrome.
