Cystic Fibrosis and Totally Implantable Vascular Access Devices

Cystic FibrosisVenous Thrombosis

The purpose of this study is to evaluate the incidence of venous thrombosis occurring on totally implantable vascular access devices in cystic fibrosis patients who need a new device (it can be the first one or a subsequent one) and to study the genetic risk factors of thrombosis adjusted to the acquired ones. It is a nationwide cohort study planned for two years with a six month follow up period. The expected number of inclusion is 50 patients each year, that is to say 100 for the whole study. In cystic fibrosis, pulmonary exacerbations necessitate repeated intravenous antibiotics, but the peripheral blood accesses become precarious with time, leading to the indication of a central venous device. It is important to take a lot of precautions to protect vascular access. This allows the patient to have a dramatic improvement in life expectancy with such life-long devices (ONM, French National Observatory France 2003 : median at 36 years). Venous thrombosis can cause a superior cava syndrome, a pleural effusion or a pulmonary embolism. The risk of thrombosis is significant; retrospectively, it has been evaluated to be between 4 and 16% in the publications. This rate may be higher due to the fact that venous thrombosis may remain asymptomatic, and therefore silent, but they lead to the same risk of vascular access loss.

MDA D-Dimer / Recurrent DVT Study

Deep Vein Thrombosis

To determine whether treatment and further investigation can be safely withheld in patients who present with suspected recurrent deep vein thrombosis (DVT) and have either a (i) negative D-Dimer or (ii) a positive D-Dimer with normal serial compression ultrasound.

Short-term Perioperative Thromboprophylaxis After Major Abdominal Surgery

Deep Vein Thrombosis

Major abdominal surgery for cancer is major risk factor for thromboembolism. Patients who undergo major abdominal surgery are prone to develop venous thromboembolism, both in the early postoperative period and after hospital discharger. There are strong recommendations in the international guidelines in favor to pharmacological thromboprophylaxis. Thus there is no consensus dor the duration of the prophylaxis. There are authors that suggest extended prophylaxis up to 4 week after surgery. On the other hand, there are prospective randomized trials that inpatient (short-term up to 7-10 days) prophylaxis is adequate.

Comparison of Different Intermittent Pneumatic Compression Devices for Deep Vein Thrombosis

Venous ThrombosisDeep Vein Thrombosis

Various kinds of intermittent pneumatic compression devices (IPC) with particular ways of compression have been developed and used for prevention of deep vein thrombosis. There are still some controversies about the physiologic properties and clinical impact of numerous issues including the variety of the cuff length, inflation rate, compression sequence, compression-relaxation cycle rate, and pressure generation characteristics. This study is designed to compare clinical efficacies as well as venous hemodynamic improvements between Simultaneous bilateral compression with fixed venous refill time versus alternate compression with adjusted refill time

Prophylactic Anticoagulation for Preventing Deep Vein Thrombosis After Total Hip Arthroplasty

Deep Vein Thrombosis

Deep vein thrombosis (DVT) remains a life-threatening complication of arthroplasty. It remains controversial for anticoagulation strategies after total hip arthroplasty (THA). A randomized double-blind study was conducted to determine whether prophylactic anticoagulation was efficient reduce DVT after THA. subjects who underwent uncemented THA were assigned to prophylactic anticoagulation group or non- prophylactic anticoagulation group. Patients were followed up 3 months later after surgery. DVT was tested by contrast venography. Investigator also used logistic regression analysis with variable selection for obtaining the prediction model of DVT. DVT after THA was affected by personal (age) and clinical factors (mechanical compression, duration of surgery). THA with short duration of surgery did not require prophylactic anticoagulation.

Apixaban Versus Warfarin for the Management of Post-operative Atrial Fibrillation

Coronary Artery Bypass GraftingPostoperative Atrial Fibrilation3 more

In this open-label, prospective, randomized pilot study, patients who develop atrial fibrillation after isolated coronary artery bypass grafting surgery will be identified. Patients with persistent atrial fibrillation (>12 hours) or recurrent sustained atrial fibrillation (>2 episodes of atrial fibrillation lasting longer than 30 minutes) will be candidates for inclusion. Upon meeting study inclusion and exclusion criteria, and after informed consent, patients will be randomized to either the standard of care (warfarin per protocol) or apixaban arms of the trial. Routine postoperative care after CABG will occur in both groups. Upon discharge, anticoagulation in both groups will be managed by the anticoagulation clinic. Patients will be followed for 30 days after surgery.

Acute Mesenteric Venous Thrombosis.. in Assiut University Hospital Management Controversies

Mesenteric Vein Thrombosis

Initial treatment in the management of acute mesenteric vein thrombosis (MVT) is controversial. Some authors have proposed a surgical approach, whereas others have advocated medical therapy (anticoagulation). In this study, the investigators analyzed and compared the results obtained with surgical and medical treatment to determine the best initial management for this disease.
