The use of haemostatic agents in thyroid surgery: efficacy and further advantages. Collagen-Fibrinogen-Thrombin Patch (CFTP) versus Cellulose Gauze.

2013

Abstract Aim: To assess the efficacy of two widely used topical haemostatic agents: oxidised regenerated cellulose gauze and Collagen-Fibrinogen-Thrombin Patch in patients undergoing total thyroidectomy. Material of study: This was a prospective, comparative, non-randomised study in which consecutive patients undergoing total thyroidectomy for benign disease received standard treatment with no haemostatic agent, cellulose gauze, or CFTP. Main outcome measures were drainage volume 24 hours after surgical procedure and the occurrence of post-operative complications (haematoma, seroma, surgical-site infection). Results: Two hundred seventy-one (271) patients undergoing total thyroidectomy for …

ABO Blood Group and Inhibitor Risk in Severe Hemophilia A Patients: A Study from the Italian Association of Hemophilia Centers

2021

AbstractConsidering the profound influence exerted by the ABO blood group system on hemostasis, mainly through the von Willebrand factor and factor VIII (FVIII) complex, we have conducted a study evaluating the possible role of blood type on the risk of inhibitor development in hemophilia A. A total of 287 consecutive Caucasian patients with severe hemophilia A (202 without FVIII inhibitors and 85 with FVIII inhibitors) followed at seven Italian Hemophilia Treatment Centers belonging to the Italian Association of Hemophilia Centers (AICE) were included in the study. A higher prevalence of O blood group was detected in patients without inhibitors as compared in inhibitor patients (55 vs. 30.…

Genetic and environmental influences on the fibrinolytic system: a twin study.

2004

SummaryThe determination of heritability is a key issue to assess the predictive power of polymorphisms for disease in clinical studies. The aim of this study was to determine the heritability of proteins and activation markers of the fibrinolytic system in a large cohort of healthy twins. Heritability was calculated as 0.76 for thrombin activatable fibrinolysis inhibitor (TAFI), 0.44 for plasminogen activator inhibitor-1 (PAI-1), and 0.43 for tissue plasminogen activator. No significant genetic influence was observed for α2-antiplasmin-plasmin-complex and D-dimer. Heritability explained by single gene polymorphisms was 25.2% for TAFI 505G>A, 31.5% for 1542C>G, and 50.0% for combinati…

Incidence, risk factors, and prognosis of gastrointestinal hemorrhage complicating acute renal failure.

2001

Incidence, risk factors, and prognosis of gastrointestinal hemorrhage complicating acute renal failure. Background Few prospective data are currently available on acute gastrointestinal hemorrhage (AGIH) as a complication of acute renal failure (ARF). The aim of the present study was to define incidence, sources, risk factors, and outcome of AGIH in patients with ARF. Methods We performed a prospective study on an inception cohort of 514 patients admitted for ARF to a nephrology intermediate care unit. Data on clinical risk factors for bleeding, frequency of occurrence of AGIH, length of hospital stay, and in-hospital mortality were collected. Independent predictors of AGIH were identified.…

Coagulation abnormalities in lacunar and cortical ischemic stroke are quite different

1998

In order to clarify the coagulation profile accompanying ischemic stroke, which may have implications on therapeutic strategies, we performed a prospective study to evaluate the hemostatic parameters in the first 24 h after the onset of cortical atherothrombotic infarct and lacunar infarction. Twenty-seven patients with cortical atherothrombotic infarction and 27 patients with lacunar infarction, diagnosed on clinical and CT-scan criteria, had blood samples taken within the first 24 h after onset of the stroke, and before anticoagulant treatment had been started. Levels of fibrinogen, von Willebrand factor, D-dimers, prothrombin factors 1 + 2, anti-thrombin III, and C-protein and S-proteins…

Endoscopic hemostasis followed by preventive transarterial embolization in high-risk patients with bleeding peptic ulcer: 5-year experience

2019

Abstract Background Upper gastrointestinal bleeding (UGIB) due to peptic ulcer disease is one of the leading causes of death in patients with non-variceal bleeding, resulting in up to 10% mortality rate, and the patient group at high risk of rebleeding (Forrest IA, IB, and IIA) often requires additional therapy after endoscopic hemostasis. Preventive transarterial embolization (P-TAE) after endoscopic hemostasis was introduced in our institution in 2014. The aim of the study is an assessment of the intermediate results of P-TAE following primary endoscopic hemostasis in patients with serious comorbid conditions and high risk of rebleeding. Methods During the period from 2014 to 2018, a tota…

Glucocorticoids as modulators of expression and activity of Antithrombin (At): potential clinical relevance.

2014

Abstract Introduction An inverse relationship has been reported between decreased postoperative Antithrombin (AT) plasmatic levels and the incidence of complications. We hypothesized that Nuclear Hormone Receptors could modulate the expression of SERPINC1 , encoding AT, through a Hormone Regulatory Element present in its promoter, and thus hormone analogs could be a pharmacological complement in surgical procedures to activate endogenous AT synthesis. Materials and Methods The expression of SERPINC1 was analyzed in HepG2 cells by quantitative RT-PCR and Western Blot. Two studies were conducted with (a) patients submitted to cardiac surgery with cardiopulmonary bypass receiving (n =17) or no…

Minor hepatic resection using heat coagulative necrosis

2009

Intra- and postoperative bleeding represents an extremely serious and frequent complication of hepatic surgery. In this study, we evaluated the effectiveness of a radiofrequency (RF) device using heat to cause coagulative necrosis of the hepatic parenchyma to control hemostasis in minor hepatic resection. Between December 2005 and November 2007, a study was conducted of 21 patients undergoing 22 hepatic resections with the RF-assisted technique. Sixteen of these were affected by hepatocellular carcinoma and five had liver metastases from colorectal cancer. Intraoperative blood loss, the need for blood transfusion, the complication rates, operating times, and the duration of postoperative h…

Minor hepatic resection for hepatocellular carcinoma in cirrhotic patients: Kelly clamp crushing resection versus heat coagulative necrosis with bipo…

2011

Hemorrhage and postoperative liver insufficiency are frequent and serious complications of hepatic resection in cirrhotic patients. The aim of this study was to assess retrospectively whether the surgical techniques using Kelly clamp crushing resection or heat coagulative necrosis with a bipolar radiofrequency device can reduce the incidence of the above complications and an eventual recurrence of neoplasia on the liver slice. We retrospectively reviewed the results of 35 patients who had undergone resection for monofocal hepatocellular carcinoma at our center. Thirteen patients (Group A) had undergone liver resection with Kelly clamp crushing resection, 22 patients (Group B) had had liver…
