Uterus transplantation in a non-human primate: long-term follow-up after autologous transplantation
2012
BACKGROUND Uterus transplantation (UTx) may provide the first available treatment for women affected by uterine infertility. The present study aimed to further develop a surgical technique for autologous UTx in a non-human primate species and to assess long-term function. METHODS Female baboons (n= 16) underwent autologous transplantation of the uterus with the Fallopian tubes and ovaries, performed with a previously published surgical technique (n= 6, Group 1) or using a modified technique (n= 10; Group 2). The uterine arteries were dissected to the proximal end of the anterior branch (Group 1) or the entire (Group 2) internal iliac artery, and the ovarian veins were dissected to the cross…
A multicenter 12-month experience with a new iliac side-branched device for revascularization of hypogastric arteries.
2016
Abstract Objective The aim of this study was to investigate the 1-year safety and efficacy of a new iliac side-branched device (IBD) for revascularization of the hypogastric arteries. Methods Patients receiving the E-liac (Jotec GmbH, Hechingen, Germany) side-branched device at six German vascular centers either as a stand-alone procedure or in combination with abdominal aortic aneurysm exclusion were included in a prospectively created data bank. Collected data were analyzed for baseline characteristics, procedural events, and clinical follow-up; variables included endoleaks, reinterventions, and internal iliac artery (IIA) patency. Results Between January 2012 and January 2015, a total of…
Preclinical report on allogeneic uterus transplantation in non-human primates
2013
Study question Is it possible to perform allogeneic uterus transplantation (UTx) with a donation from a live donor in a non-human primate species and what immunosuppression is needed to prevent rejection? Summary answer Allogeneic UTx in the baboon is a donor- and recipient-safe surgical procedure; immunosuppression with induction therapy and a triple protocol should be used. What is known already UTx may become a treatment for absolute uterine factor infertility. Autologous UTx models have been developed in non-human primates with reports on long-term survival of the uterine grafts. STUDY DESIGN, SIZEAND DURATION: This experimental study included 18 female baboons as uterus donors and 18 f…
Early calcification patterns of the iliac arteries and their relation to the arterial structure
1972
Gross calcifications of the common iliac and internal iliac arteries represent a common finding in newborn children and infants. In both arteries, the calcific deposits regularly appear in certain areas of the arterial luminal surface only, whereas the other parts of the arterial wall remain free of gross lesions even in cases with a pronounced calcification. In the common iliac artery, the lateral wall of the vessel and the adjacent sectors of the anterior and posterior wall represent the predilection site of calcific deposits. In the internal iliac artery, the gross calcifications have been regularly demonstrated in the dorso-medial wall. The predominant localisation of the calcification …
Initial Experience in the Treatment of Extensive Iliac Artery Aneurysms With the Nellix Aneurysm Sealing System.
2016
Purpose: To assess the feasibility and effectiveness of the Nellix prosthesis in the treatment of common iliac artery aneurysms. Methods: Between May 2013 and June 2015, 230 patients underwent implantation of the Nellix device at 2 institutions. Fifty of these patients (mean age 76 years; 35 men) were identified as having 60 common iliac artery aneurysms (CIAAs) with a median diameter of 4 cm (range 3.5–7). The majority of patients had aortoiliac aneurysms (5, 70%), 10 (20%) had isolated CIAAs, and 5 (10%) had iliac anastomotic aneurysms after aortoiliac bypass. In 20 patients, the iliac aneurysm was the indication for the intervention; in the other 30 patients, the endovascular iliac repa…
Pheochromocytoma in the Pediatric Age Group: The Prostate—An Unusual Location
1990
AbstractPheochromocytomas of the prostate are rare, with only 3 cases in adults reported in the literature. We present the case of an 8-year-old boy with a pheochromocytoma of the prostate and a second tumor in the region of the left internal iliac artery. (J. Urol., 144: 1219–1221, 1990)
Ureteroiliac Artery Fistula in a Young Woman with Short Bowel Syndrome for Radiation Enteritis
2010
Ureteral-iliac artery fistula is a rare and potentially life-threatening complication, typically occurring after radiation therapy in already surgically treated cancer patients. This case report describes the diagnostic challenges and the successful management, with the positioning of an intra-arterial prosthesis, of a fistula between the internal iliac artery and the left ureter presenting as massive hematuria in a young woman with history of total colectomy and pelvic radiotherapy for rectal cancer and subsequent wide ileal resections and bilateral ureteral stent positioning for radiation enteritis. Ureteroiliac artery fistulas require a prompt diagnosis and intervention, to avoid life th…
Follow-up results of embolization therapy for palliation of incurable bladder carcinoma
1985
Embolization therapy of the renal artery (N=10), hypogastric arteries (N=18) and ureter (N=24) was performed in 41 patients with incurable bladder carcinoma for palliation of gross hematuria and severe dysuria. Careful follow-up of the patients until death gave a mean survival time of 12.3 months after embolization; 6 patients are still alive. The results show that embolization therapy is justified for management of bleeding and dysuric complaints. Ureteral occlusion alone has almost no effect on hematuria. Combined embolization procedures yield better results than occlusion of the vessels or the ureter. Ureteral occlusion with a detachable balloon is superior to embolization with tissue ad…
