Non-occlusive mesenteric Ischemia (NOMI) in Parkinson’s disease: Case report

2017

Non-occlusive mesenteric ischemia (NOMI) is a severe pathological condition characterized by signs and symptoms of bowel obstruction, intestinal necrosis resulting from acute and/or chronic inadequate blood perfusion, in the absence of an organic vascular obstruction detectable by imaging techniques. A 64 years old man case with a history of Parkinson’s disease in high-functioning levodopa treatment is presented. Clinical and radiological signs of intestinal obstruction were observed. He underwent surgical operation with total colectomy and terminal ileostomy for generalized secondary peritonitis due to perforation of sigmoid colon. Ischemic pancolitis was first suspected. In third post-o…

A clampless and sutureless aortic anastomosis technique using an endograft connector for aortoiliac occlusive disease in which the aorta cannot be cl…

2012

Bypass surgery in aortoiliac or aortofemoral occlusive disease can be technically demanding and hazardous due to huge calcifications and/or patient co-morbidities. We report about mid-term results of a telescoping sutureless aortic anastomosis technique using endografts as connectors to address such challenging situations. This is a single-center experience (2004–2011) in seven patients (63 ± 6 years) requiring aortoiliac (three) or aortofemoral (four) bypass surgery. In six cases, an aortic stent graft was telescoped into the infrarenal aorta and partly deployed within the aorta and partly outside the aorta. In the first case, a bifurcated stent graft was deployed and the iliac legs were …

A minimally invasive approach for aortobifemoral bypass procedure

2011

Surgical aortobifemoral bypass procedure for aortoiliac occlusive disease remains the gold standard treatment despite rapidly expanding range of indications for endovascular repair. Besides several disadvantages such as dysparaesthesias, hernias, and unpleasant outcome, transperitoneal exposure of the aorta is also associated with operative autonomic nerve injury. In five male patients, infrarenal aorta was exposed through a small (8 cm) supraumbilical midline incision. Incision of the posterior peritoneum above the infrarenal aorta was limited to 3 cm. A 1 cm infraumbilical incision allowed transperitoneal placement of the distal aortic clamp outside of the operative field. Four centimeter…

Long-Term Results of Stenting of the Aortic Bifurcation

2012

Background To evaluate the long-term results in a multicentric continuous series of narrowing lesions of the aortic bifurcation treated with a kissing stent. Methods From January, 1st 1999 to the December, 31st 2001, all of the patients ( n = 80) presenting with stenosis of the aortic bifurcation ( n = 15) and/or the 2 common iliac arteries ( n = 65), treated with a kissing stent, in 8 teaching hospitals were collected retrospectively. The risk factors were smoking (91%), dyslipidemia (60%), arterial hypertension (42%) and diabetes (27%). In 84% of cases, the indication for treatment was claudication. The lesions were stenotic n = 76) and/or thrombotic ( n = 18). The associated lesions were…

Testosterone Levels in Males with Type 2 Diabetes and Their Relationship with Cardiovascular Risk Factors and Cardiovascular Disease

2010

ABSTRACT Introduction One of the factors involved in type 2 diabetes in males is a reduction in levels of testosterone, which has been shown to predict resistance to insulin and the development of cardiovascular diseases. Aim To assess the levels of testosterone in patients with type 2 diabetes and to evaluate their relationship with cardiovascular risk factors, peripheral arterial disease (PAD) and silent myocardial ischemia (SMI). Methods Total testosterone and sex hormone binding globulin were measured and free and bioavailable testosterones were calculated using Vermeulen's formula. Levels of total testosterone ≥12 nmol/L or free testosterone >225 pmol/L were considered normal. PAD was …

Die dynamische31Phosphor-Magnetresonanz-Spektroskopie des M. quadriceps: Therapiebedingte Veränderungen bei arterieller Verschlußkrankheit

1997

PURPOSE: The present investigation aimed at examining changes in muscle metabolism caused by treatment of arterial occlusive disease, using dynamic 31-phosphorus methods. METHOD: 32 patients with arterial occlusive disease were examined in a 1.5 T apparatus with a 6 cm surface coil before and after treatment. The metabolic changes in the quadriceps muscles were visualised during a 36 s phosphorus spectrum during rest, exercise (isometric and isotonic) and during a period of recovery. RESULTS: Vascular therapy resulted in a significant increase in the duration of both types of exercise during dynamic phosphorus spectroscopy (isometric exercise: 282 s against 199 s: p = 0.002, isotonic exerci…

Comprehensive three‐dimensional morphology of neoangiogenesis in pulmonary veno‐occlusive disease and pulmonary capillary hemangiomatosis

2019

Abstract Pulmonary veno‐occlusive disease (PVOD) is a rare lung disease characterized by fibrotic narrowing of pulmonary veins leading to pulmonary hypertension (PH) and finally to death by right heart failure. PVOD is often accompanied by pulmonary capillary hemangiomatosis (PCH), a marked abnormal proliferation of pulmonary capillaries. Both morphological patterns often occur together and are thought to be distinct manifestations of the same disease process and accordingly are classified together in group 1′ of the Nice classification of PH. The underlying mechanisms of these aberrant remodeling processes remain poorly understood. In this study, we investigated the three‐dimensional struc…

USEFULNESS OF CT COLONOGRAPHY IN PATIENTS WITH OCCLUSIVE COLORECTAL CANCER BEFORE METALLIC STENT PLACEMENT: A SINGLE ENTER EXPERIENCE

2015

Up to 15% of patients with colorectal cancer (CRC) present with large bowel obstruction. Currently, computed tomography colonography (CTC) is regarded as a promising technique for complete evaluation of the proximal colon and simultaneous assessment of extraluminal status. Aim of this retrospective, observational study is to evaluate the feasibility of using CTC for preoperative examination of the proximal colon before metallic stgent placement in patients with colon obstruction caused by CRC. Sixteen patients who demonstrated colonic obstruction caused by CRC, underwent CTC immediately after incomplete colonoscopy. Per-patient sensitivity of CTC for lesion 5 mm larger in diameter in the co…

External Volume Expansion Increases Subcutaneous Thickness, Cell Proliferation, and Vascular Remodeling in a Murine Model

2012

Background Fat grafting is a powerful tool for soft-tissue reconstruction; however, the science behind recipient bed preparation has not been thoroughly explored. External volume expansion using suction before fat grafting has been used clinically to improve reliability and consistency of graft survival. The authors developed a murine model to investigate the underlying mechanism of external volume expansion. Methods The authors created an external volume expansion device using a soft-silicone dome connected to a vacuum source (25 mmHg) to treat the dorsum of mice, and the response was compared with treatment with an occlusive dressing. Treated areas were monitored with magnetic resonance i…
