A high index of suspicion for NOMI in patients with the above-mentioned risk factors may decrease the diagnostic and therapeutic delay. To identify at-risk patients the developed risk equation is a useful tool with a high specificity.

Paclitaxel-coated balloon angioplasty of central vein restenosis in patients with hemodialysis shunts yields a statistically significant longer freedom from TLR compared to standard balloon angioplasty.

In patients with suspected NOMI, using our scoring system yields high intra- and inter-observer correlations, allowing a standardized evaluation of angiographic findings.

Background Even though bleeding and thromboembolic events are major complications of extracorporeal membrane oxygenation (ECMO), data on the incidence of venous thrombosis (VT) and thromboembolism (VTE) under ECMO are scarce. This study analyzes the incidence and predictors of VTE in patients treated with ECMO due to respiratory failure.MethodsRetrospective analysis of patients treated on ECMO in our center from 04/2010 to 11/2015. Patients with thromboembolic events prior to admission were excluded. Diagnosis was made by imaging in survivors and postmortem examination in deceased patients.ResultsOut of 102 screened cases, 42 survivors and 21 autopsy cases [mean age 46.0 ± 14.4 years; 37 (58.7 %) males] fulfilling the above-mentioned criteria were included. Thirty-four patients (54.0 %) underwent ECMO therapy due to ARDS, and 29 patients (46.0 %) with chronic organ failure were bridged to lung transplantation. Despite systemic anticoagulation at a mean PTT of 50.6 ± 12.8 s, [VT/VTE 47.0 ± 12.3 s and no VT/VTE 53.63 ± 12.51 s (p = 0.037)], VT and/or VTE was observed in 29 cases (46.1 %). The rate of V. cava thrombosis was 15/29 (51.7 %). Diagnosis of pulmonary embolism prevailed in deceased patients [5/21 (23.8 %) vs. 2/42 (4.8 %) (p = 0.036)]. In a multivariable analysis, only aPTT and time on ECMO predicted VT/VTE. There was no difference in the incidence of clinically diagnosed VT in ECMO survivors and autopsy findings.ConclusionsVenous thrombosis and thromboembolism following ECMO therapy are frequent. Quality of anticoagulation and ECMO runtime predicted thromboembolic events.

The applied scoring system allows standardized interpretation of angiographic findings in NOMI patients. Beyond that the score seems to correlate well with risk factors of NOMI and outcome.

Background: Even though bleeding and thromboembolic events are major complications of extracorporeal membrane oxygenation (ECMO), data on the incidence of venous thrombosis (VT) and thromboembolism (VTE) under ECMO are scarce. This study analyzes the incidence and predictors of VTE in patients treated with ECMO due to respiratory failure. Methods:Retrospective analysis of patients treated on ECMO in our center from 04/2010 to 11/2015. Patients with thromboembolic events prior to admission were excluded. Diagnosis was made by imaging in survivors and postmortem examination in deceased patients.Results: Out of 102 screened cases, 42 survivors and 21 autopsy cases [mean age 46.0 ± 14.4 years; 37 (58.7 %) males] fulfilling the above-mentioned criteria were included. Thirty-four patients (54.0 %) underwent ECMO therapy due to ARDS, and 29 patients (46.0 %) with chronic organ failure were bridged to lung transplantation. Despite systemic anticoagulation at a mean PTT of 50.6 ± 12.8 s, [VT/VTE 47.0 ± 12.3 s and no VT/VTE 53.63 ± 12.51 s (p = 0.037)], VT and/or VTE was observed in 29 cases (46.1 %).

Obesity seems to be an independent risk factor for insufficient sealing using the AngioSeal vascular closure device after antegrade puncture of the CFA. In 8% of our patients, hemostasis could not be achieved due to kink of the flexible sheath.

Background: Patients with a forced expiratory volume in 1 s (FEV₁) below 20% of the predicted normal values (pred.) and either homogeneous emphysema or low diffusing capacity for carbon monoxide (DLCO) have a high risk for adverse events including death when undergoing surgical lung volume reduction. Objectives: We hypothesized that selected patients can benefit from endoscopic lung volume reduction (eLVR) despite a very low FEV₁. Methods: This study is a retrospective analysis of consecutive patients with severe airflow obstruction, an FEV₁ ≤20% of pred., and low DLCO who were treated by eLVR with endobronchial valves (EBV) between June 2012 and January 2015. Pre- and postinterventional lung function parameters, the 6-min walking test (6-MWT) distance, adverse events, and follow-up were recorded. Results: In 20 patients, there was an overall improvement in lung function with an increase in FEV₁ (16.97-21.03% of pred.) and a decrease in residual volume (322-270% of pred.) and total lung capacity (144-129.06% of pred.). The 6-MWT distance improved (from 239 ± 77 to 267± 97 m overall, and from 184 ± 50 to 237 ± 101 m if patients developed an atelectasis of the target lobe). Pneumothorax occurred in 5 of the 20 patients (25%). 30-day mortality was 0%, and all patients survived to discharge. Conclusions: The patients benefitted moderately from EBV treatment despite an initially low FEV₁. Some patients improved remarkably. EBV treatment in patients with an FEV₁ ≤20% of pred. is generally feasible and safe. The greatest risk is pneumothorax with prolonged chest tube duration.
