Intraoperative C-arm CT imaging in angular stable plate osteosynthesis of distal radius fractures

2013

The purpose of this study was to analyze the practicability and benefit of intraoperative C-arm computed tomography (CT) imaging in volar plate osteosynthesis of unstable distal radius fractures. During a 1 year period, intraoperative three dimensional (3D) imaging with the ARCADIS Orbic 3D was performed in addition to standard fluoroscopy in 51 cases. The volar angular stable plate oesteosyntheses were analyzed intraoperatively and, if necessary, improved immediately. The duration of the scan and radiation exposure dose were measured. On average, performance of the scan and analysis of the CT dataset took 6.7 minutes. In 31.3% of the surgeries a misplacement of screws was detected and cor…

Bowel perforation in Crohn's Disease: correlation between CDAI and Clavien-Dindo scores

2018

Background Many studies have elaborated different kind of activity indices for Crohn's Disesase (CD) with the endpoint of univocally measure and evaluate the gravity of its lesions and symptoms. Aim Purpose of this work is to study and define the correlation that runs between the preoperative score obtained at the Crohn's Disease Activity Index, the occurrence of postoperative complications that will require re-intervention and the severity of the postoperative lesions evaluated using the Clavien-Dindo score. Patients and methods We have collected and analyzed data from 23 patients (12 males, 11 females) that in a period that spans from 2010 to 2016 had been recovered in our Operative Unit …

Patients requiring interruption of long-term oral anticoagulant therapy: the use of fixed sub-therapeutic doses of low-molecular weight heparin.

2009

Introduction: We tested the efficacy and safety of fixed doses of Low-Molecular Weight Heparin (LMWH) in patients requiring interruption of Vitamin-k Antagonist (VKA) because of invasive procedures Methodology: Pre-operatively, patients discontinued VKA 5 +/- 1days; in those at low-risk for thrombosis, LMWH was given at a prophylactic dosage of 3.800 U.I. (nadroparin) or 4.000 U.I. (enoxaparin) anti-FXa once daily the night before the procedure. In patients at high-risk for thrombosis, LMWH was started early after VKA cessation and given at fixed sub-therapeutic doses (3.800 or 4.000 UI anti-FXa twice daily) until surgery. Post-operatively, LMWH was reinitiated 12 hours after procedure whil…

Short-and long-term outcome after PTCA in patients with stable and unstable angina

1990

Acute results and follow-up data over a period of 36 months after attempted PTCA in 406 patients with stable angina and 202 patients with unstable angina are reported. The rate of acute complications (death, myocardial infarction and bypass grafting (CABG) amounted to 1.5% in stable and 6.4% in unstable patients (P less than 0.005). Within the first week after PTCA a significantly lower percentage (1.7% vs 10.4%) of cardiac events (death, myocardial infarction, CABG and repeat PTCA) was observed in the stable group (P less than 0.001). During a 12-month follow-up period, another 16.3% of the patients in the stable group and 30.7% of unstable patients suffered a new cardiac event (P less tha…

Biomarker profile predicts clinical efficacy of extracorporeal photopheresis in steroid‐resistant acute and chronic graft‐vs‐host disease after allog…

2021

We conducted a multicenter interventional study to assess the efficacy of Therakos ECP to treat steroid-resistant graft-vs-host disease (SRes-GVHD) after allogeneic HSCT and to identify biomarkers of GVHD response. A total of 62 patients were treated for acute SRes-GVHD (n = 37) or chronic SRes-GVHD (n = 25). Median time to best response was 35 days (range, 28-85) and 90 days (range, 27-240) in acute and chronic SRes-GVHD, respectively. Overall, 27 patients (72.9%) with SRes-aGVHD responded to treatment (40.5% CR and 32.4% PR). The response rate was significantly higher in grade I-II than in grade III-IV aGVHD (100% vs 50.0%, respectively, P-value = .001). In chronic SRes-GVHD, 22 patients …

Evaluation of posttreatment response of hepatocellular carcinoma: comparison of ultrasonography with second-generation ultrasound contrast agent and …

2010

We evaluated the ability of one-month follow-up contrast-enhanced ultrasound (CEUS) with second-generation contrast agent in monitoring radio frequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) treatments of hepatocellular carcinoma (HCC). One-hundred forty-eight HCCs were studied using CEUS: 110 nodules were treated with RFA [41/110 RFA were performed using a pretreatment and an immediate postablation evaluation using CEUS (group 1); 69/110 using only US guidance (group 2)] and 38 nodules treated with TACE. For statistical analysis, McNemar test was used. Overall complete response was observed in 107/148 nodules (92/110 treated with RFA and 15/38 with TACE). A bett…

Mini-Invasive Approach Contributes to Expand the Indication for Liver Resection for Hepatocellular Carcinoma Without Increasing the Incidence of Post…

2016

Liver resection (LR) for hepatocellular carcinoma (HCC) is the best alternative option for increasing the survival of many patients with intermediate or advanced stages of the Barcelona Clinic Liver Cancer staging classification. Mini-invasive approach may play a positive role in treating a tumor rising almost exclusively in a diseased liver.A prospectively collected database was retrospectively reviewed for 167 consecutive patients who underwent LR between 1999 and 2015.A total of 38 LRs were performed from 1999 to 2009 (Period I), and 129 between 2010 and 2015 (Period II). Laparoscopic procedures increased from 5.3% to 38.1%. Not undergoing laparoscopic LR increased length of stay, and Cl…

Liver transplantation for hepatocellular carcinoma--is there a risk of recurrence caused by intraoperative blood salvage autotransfusion?

2011

<i>Background/Aims:</i> The use of intraoperative blood salvage autotransfusion (IBSA) during surgical approaches may contribute to tumour cell dissemination. Therefore, IBSA should be avoided in cases of malignancy. However, the risks of IBSA might be acceptable in liver transplantation (LT) for selected small hepatocellular carcinoma (HCC). <i>Methods:</i> In total, 136 recipients of LT with histologically proven HCC in the explanted liver were included in this analysis. With regard to tumour recurrence, 40 patients receiving IBSA despite HCC (IBSA group) were compared to 96 patients without IBSA (non-IBSA group). <i>Results:</i> Milan criteria as asses…

Noninvasive Hemodynamic Measurements During Neurosurgical Procedures in Sitting Position.

2017

Neurosurgical procedures in sitting position need advanced cardiovascular monitoring. Transesophageal echocardiography (TEE) to measure cardiac output (CO)/cardiac index (CI) and stroke volume (SV), and invasive arterial blood pressure measurements for systolic (ABPsys), diastolic (ABPdiast) and mean arterial pressure (MAP) are established monitoring technologies for these kind of procedures. A noninvasive device for continuous monitoring of blood pressure and CO based on a modified Penaz technique (volume-clamp method) was introduced recently. In the present study the noninvasive blood pressure measurements were compared with invasive arterial blood pressure monitoring, and the noninvasive…
