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…

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…

Continent diversion with the Mainz pouch.

1996

From 1983 until July 1994, 561 patients in 2 urology departments (Mainz and Wuppertal) underwent a Mainz pouch 1 procedure. The Mainz pouch 1 was used for bladder augmentation in 60 patients, for orthotopic bladder substitution in 61 patients, and for continent cutaneous urinary diversion in 440 patients. In the group of continent cutaneous urinary diversion, the continence mechanism applied was an ileal intussusception nipple in 270 patients, an appendix stoma in 146 patients, a submucosal seromuscular bowel-flap tube in 14 patients, and a submucosal full-thickness bowel-flap tube in 10 patients. Indications for urinary diversion were bladder cancer in 339 patients, anatomical or functiona…

A noninvasive postoperative clinical score to identify patients at risk for postoperative pulmonary complications: The air-test score

2020

BACKGROUND: Postoperative pulmonary complications (PPCs) negatively affect morbidity, healthcare costs and postsurgical survival. Preoperative and intraoperative peripheral oxyhemoglobin saturation (SpO2) levels are independent risk factors for postoperative pulmonary complications (PPCs). The air-test assesses the value of SpO2 while breathing room-air. We aimed at building a clinical score that includes the air-test for predicting the risk for PPCs. METHODS: This is a development and validation study in patients -randomly divided into two cohorts- from a large randomized clinical trial (iPROVE) that enrolled 964 intermediate-to-high risk patients scheduled for abdominal surgery. Arterial …

Treatment of early childhood medulloblastoma by postoperative chemotherapy alone.

2005

The prognosis for young children with medulloblastoma is poor, and survivors are at high risk for cognitive deficits. We conducted a trial of the treatment of this brain tumor by intensive postoperative chemotherapy alone.After surgery, children received three cycles of intravenous chemotherapy (cyclophosphamide, vincristine, methotrexate, carboplatin, and etoposide) and intraventricular methotrexate. Treatment was terminated if a complete remission was achieved. Leukoencephalopathy and cognitive deficits were evaluated.Forty-three children were treated according to protocol. In children who had complete resection (17 patients), residual tumor (14), and macroscopic metastases (12), the five…

Definition of the Rectum An International, Expert-based Delphi Consensus

2019

Mini: A radiological, anatomic distinction between the rectum and sigmoid colon was agreed by consensus of international experts in rectal cancer using the Delphi Technique. Use of this landmark, “the sigmoid take-off,” may harmonize efforts in research and clinical practice to improve patient outcomes. Background: The wide global variation in the definition of the rectum has led to significant inconsistencies in trial recruitment, clinical management, and outcomes. Surgical technique and use of preoperative treatment for a cancer of the rectum and sigmoid colon are radically different and dependent on the local definitions employed by the clinical team. A consensus definition of the rectum…

Traumatic arteriovenous fistula as consequence of TMJ arthroscopic surgery. A case report

2016

The ocurrence of a traumatic arteriovenous fistula after arthroscopic surgery of TMJ represents an extremely rare event. Specifically, this uncommon complication has been described only in a few case reports. In this light, the most frequent symptoms showed by this disease are thrills, bruits, pulsatile tinnitus, and an expansible vascular mass. Importantly, the severity of these symptoms is also dependent on the vessels involved. With regard to the management, is important to note that the vessel ligation with surgery as well as vessel emolization with endovascular procedures have been shown to be effective in the treatment of these cases. In view of that, the present study describes a cas…
