Systemic pulsatile pressure in type II endoleaks after stent grafting of experimental abdominal aortic aneurysms.
2003
Purpose: To investigate pressure and maximum rate of rise of systolic pressure (peak dP/dt) in completely excluded aneurysms and endoleaks to determine the hemodynamic impact of endoleaks. Methods: In mongrel dogs (n = 36) experimental aneurysms were created by insertion of a patch (portion of rectus abdominis muscle sheath) into the infrarenal aorta. In group I (n = 18), all aortic branches of the aneurysm were ligated and all aneurysms were completely excluded by stent grafts. Group II (n = 18) consisted of aneurysms with patent aortic side branches that represented sources of endoleaks. One week (n = 12), six weeks (n = 12), and six months (n = 12) after stent grafting, hemodynamic measu…
Use of Marginal Donors in Kidney Transplantation: Our Experience
2006
The use of elderly donors has been advocated to expand the organ donor pool because of increased needs and the organ shortage. The aim of this study was to analyze whether the use of elderly donors and marginal kidneys affected the outcome of renal transplantations. Herein we presented data on 126 kidney transplantations performed from January 1996 to September 2003 using 32 marginal donors (group A) and 94 ideal donors (group B). We analyzed the medical and surgical complications and the graft survivals at a median follow-up of 18 months. Medical and surgical complications occurred in 22% and 5% versus 7% and 4% in groups A and B, respectively. The mean cold ischemia time and the mean age …
Follow-up after urinary diversion.
1999
With modern forms of urinary diversion being widely employed during recent years, the awareness of possible complications and appropriate follow-up strategies gains rising importance and current follow-up strategies are reviewed herewith. Follow-up investigations after urinary diversion have to address possible surgical complications, metabolic changes as well as the risk of secondary malignancies in the incorporated bowel segments. The most important and possible deleterious surgical complication is upper tract dilation and obstruction following ureteroenteric anastomotic stenosis and occurs in 2–30% depending on the surgical technique and evaluated series. The most appropriate follow-up s…
Transverse Small Skin Incision for Carotid Endarterectomy
2015
The purpose of this report is to determine the feasibility of short transverse skin incision (STI4 cm) for eversion (EEA) and patch (PEA) endarterectomy with or without shunt by comparing it with the outcomes after long transverse skin incision (LTI 4-8 cm).Of 164 elective consecutive patients (71 ± 2.73% symptomatic) operated at one institution over 24 months, 81 were treated with STI, while 83 patients received LTI. The LTI and STI groups did not differ in terms of age, symptoms, or risk factors. EEA or PEA under locoregional (LRA) or general (GA) anesthesia were performed.STI was associated with shorter operation times (75.19 ± 15.33 vs. 94.87 ± 41 and 99.4 ± 27.36 vs. 132.66 ± 51.32, re…
Posttraumatic chronic cranial osteomyelitis due to a superficial wound - A clinical and neuroradiological case report
2019
Background: Osteomyelitis is a progressive infection of bone and bone marrow by microorganisms, resulting in inflammatory destruction of bone, bone necrosis, and new bone formation. Skull involvement is a rare occurrence which mainly affects children with chronic inflammatory diseases of paranasal sinusitis, or malignant otitis. In adults, cranial vault osteomyelitis can occur after cranial surgery or head trauma. Case Description: We describe an unusual case of chronic cranial osteomyelitis occurred 3 months following a mild traumatic brain injury. The causative mechanisms along with the diagnostic modalities are discussed. Conclusion: Focal cranial vault osteomyelitis, in the absence of …
Never say never again: A bone graft infection due to a hornet sting, thirty-nine years after cranioplasty
2017
Background: Cranioplasty (CP) is a widespread surgical procedure aimed to restore skull integrity and physiological cerebral hemodynamics, to improve neurological functions and to protect the underlying brain after a life-saving decompressive craniectomy (DC). Nevertheless, CP is still burdened by surgical complications, among which early or late graft infections are the most common outcome-threatening ones. Case Description: We report the case of 48-year-old man admitted to our neurosurgical unit because of a painful right frontal swelling and 1-week purulent discharge from a cutaneous fistula. He had been undergone frontal CP because of severe traumatic brain injury (TBI) when he was 9-ye…
Intravitreal dexamethasone implant for cystoid macular edema and inflammation after scleral buckling
2015
Purpose Cystoid macular edema may occur following scleral buckling and therefore deteriorate the visual outcome. Inflammation may be the major causative factor in the development of postoperative cystoid macular edema. This case demonstrates the effectiveness of a dexamethasone implant as a treatment after the onset of choroidal inflammation and cystoid macular edema 6 months following scleral buckling and having visual acuity restored. Methods A 59-year-old phakic woman treated with scleral buckling for macula-off retinal detachment presented 2 months after surgery with cystoid macular edema with choroidal inflammation. Optical coherence tomography and fluorescein angiography were performe…
Ischemic Type Biliary Lesions nach orthotoper Lebertransplantation - ein immunologisches Problem?
2004
Ischemic type biliary lesions (ITBL) are a major complication following orthotopic liver transplantation (OLT). In many cases re-OLT is indicated. Multiple factors have been claimed to be reasonable for ITBL; here we present a new immunological risk factor: CC-Chemokines play a key role in the recruitment of leukocytes during ischemia-reperfusion damage and acute rejection. Therefore the CC-chemokine-receptor 5 (CCR5) and its functionless CCR5-delta-32-polymorphism (CCR5Δ32) might have an influence on the grafts pathology after OLT. In 146 patients after OLT the CCR5 was analyzed with regard to the CCR5Δ32 by PCR. 120 patients (82,1%) showed a normal receptor (wildtype) whereas 26 patients …
Extracorporeal shock wave lithotripsy with ultrasound-guided lithostar plus.
1992
Abstract Since 1989, the Siemens lithostar plus, an upgrade of the lithostar with the ultrasonically guided overhead module, has been available for clinical use. This unit may be used for the treatment of either biliary or urinary calculi. We report on 75 patients with urinary calculi treated between March 1989 and June 1990 with the lithostar overhead module. Stone localization showed a rate of: caliceal stones 33.5%, pelvic stones 44%, upper ureteral stones 9.3% and lower ureter stones 13%. The overall disintegration rate was 86%, with a stone-free rate after 3 months of 78%.
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…
