Abstract
Pulmonary embolism (PE) is the third most common cause of cardiovascular death. Every specialty of medical practitioner will encounter PE in their patients, and should be prepared to employ contemporary strategies for diagnosis and initial risk-stratification. Treatment of PE is based on risk-stratification, with anticoagulation for all patients, and advanced modalities including systemic thrombolysis, catheter-directed therapies, and mechanical circulatory supports utilized in a manner paralleling PE severity and clinical context.

Abstract
Background: There is a high incidence of venous thromboembolism (VTE) during the perioperative period for cancer. Therefore, there is an urgent need to elucidate the perioperative onset and appropriate prophylaxis for VTE. Purpose: VTE during the perioperative period for colorectal cancer was evaluated by lower limb venous ultrasonic examinations (lower limb echo) under enoxaparin prophylaxis. We also examined the relationship between hemorrhagic adverse events and anti-Xa factor activity. Patients and methods: Eighty-three subjects who underwent lower limb echo during the perioperative period for colorectal cancer were prospectively included. Enoxaparin was administered for 5 days, from day 1 to day 5 after surgery. Lower limb echo was performed before surgery and on day 5 after surgery. The activated partial thromboplastin time, D-dimer levels, and anti-Xa factor activity were measured before surgery and on days 1, 3, 5, 7, and 9 after surgery. Results: VTEs before surgery were observed on lower limb echo for 16 patients (19.2%). Three patients (3.6%) had a new thrombus during the perioperative period. The preoperative D-dimer level was an independent prognostic factor for newly formed postoperative VTEs (p=0.0036; odds ratio, 19.37). Three patients (3.6%) had hemorrhagic events; however, there was no significant trend for anti-Xa factor activity. Conclusion: VTE prevention using enoxaparin was relatively safe, and D-dimer measurements before surgery were useful for predicting perioperative VTE.

Rapid development of a spinal epidural hematoma following thoracic epidural catheter removal in an esophageal carcinoma surgical patient: a case report. JA Clin Rep 2016; 2:37. [PMID: 29492432 PMCID: PMC5813771 DOI: 10.1186/s40981-016-0060-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2016] [Accepted: 11/04/2016] [Indexed: 11/10/2022] Open
Abstract
Background The occurrence of spinal epidural hematomas associated with the use of epidural catheters is relatively rare. Furthermore, it is unusual for hematoma-associated neurological symptoms to occur within 15 min of removing a catheter. Here, we report our experience with an esophageal carcinoma surgical patient who developed an epidural hematoma almost immediately after catheter removal, resulting in paralysis of his lower extremities. The patient achieved full neurological recovery following prompt diagnosis and surgical intervention. Case presentation A 68-year-old man was admitted with esophageal carcinoma and underwent video-assisted thoracoscopic esophagectomy followed by posterior mediastinal gastric tube reconstruction. During surgery, the patient was administered both general and epidural anesthesia. The epidural catheter was inserted approximately 5 cm into the epidural space at the Th6–7 level. The patient was extubated the following day in the general intensive care unit. Two days after surgery, the d-dimer level was high at 36.9 μg/mL (reference range 0–0.9 μg/mL), and we decided to administer an anticoagulant (enoxaparin sodium) to prevent thrombosis. The epidural catheter was removed 2 h prior to the scheduled administration of enoxaparin sodium. However, the patient reported a complete lack of strength in his lower extremities 15 min after catheter removal. Upon examination, the manual muscle testing score was 1 out of 5, and the patient experienced impaired touch sensation and cold sensation below Th4. An emergency magnetic resonance imaging scan was performed 2 h after catheter removal, which revealed a possible spinal epidural hematoma spreading from Th3 to Th6. Three hours after catheter removal, we began emergency surgery to evacuate the hematoma, which had spread to Th7. After surgery, the patient showed improvements in touch sensation, cold sensation, and motor function. The patient was able to walk 2 days after hematoma removal. Conclusions It is highly unusual for a spinal epidural hematoma to develop so rapidly after the removal of an epidural catheter. This case emphasizes the need for vigilant patient monitoring, rapid diagnosis, and prompt surgery to ensure adequate neurological recovery in these patients.

Abstract
The use of plasma D-dimer assay has been advocated for the exclusion of pulmonary embolism. We retrospectively looked at 840 patients in whom both ventilation-perfusion scan and D-dimer assay were performed within 48 h. The negative predictive value of a negative D-dimer assay was 96% for emergency admissions and 98% for inpatients. We present the cases of two patients with negative D-dimer assay results who had a high-probability lung scan, and we have found a further three patients with negative D-dimer assay results who had an intermediate-probability lung scan.

Abstract
OBJECTIVES The objective was to determine the incremental benefit of a shortness-of-breath (SOB) point-of-care biomarker panel on the diagnostic accuracy of emergency department (ED) patients presenting with dyspnea. METHODS Adult ED patients at 10 U.S. EDs with SOB were included. The physician's estimates of the pretest clinical probability of heart failure (HF), acute myocardial infarction (MI), and pulmonary embolism (PE) were recorded using deciles (0%-100%). Blood samples were analyzed using a SOB point-of-care biomarker panel (troponin I, myoglobin, creatinine kinase-myocardial band isoenzyme [CK-MB], D-dimer, and B-type natriuretic peptide [BNP]). Thirty-day follow-up for MI, HF, and PE was performed. Data were analyzed using logistic regression and receiver operating characteristics (ROC) curve analysis. RESULTS Of 301 patients, the mean (+/-standard deviation [SD]) age was 61 (+/-18) years; 56% were female, 58% were white, and 38% were African American. Diagnoses included MI (n = 54), HF (n = 91), and PE (n = 16) in a total of 129 (43%) of the patients. High pretest clinical certainty (>or=80%) identified 60 of these 129 (46.5%) cases. The SOB point-of-care biomarker panel identified 66 additional cases of MI (n = 24), HF (n = 31), and PE (n = 11). The overall adjusted sensitivity for any diagnosis was increased from 65% to 70% with the addition of the SOB point-of-care biomarker panel (difference = 5%, 95% CI = -1.1% to 11%) while specificity was increased from 82% to 83% (difference = 1%, 95% CI = -4% to 7%). The model containing pretest probability and the results of the SOB panel had an area under the curve (AUC) of 83.4% (95% CI = 78.4% to 88.5%), which was not significantly better than the AUC of 80.4% (95% CI = 75.1% to 85.7%) for clinical probability alone. CONCLUSIONS The addition of the SOB panel of markers did not improve the AUC for diagnosing the combined set of clinical conditions. Using the disease-specific SOB biomarkers increased the sensitivity on a disease-by-disease basis; however, specificity was reduced.

Ventilation/perfusion lung scintigraphy: what is still needed? A review considering technetium-99m-labeled macro-aggregates of albumin. Ann Nucl Med 2009; 23:1-16.

Abstract
Lung perfusion scintigraphy (LPS) with technetium-99m-labeled macro-aggregates of albumin (Tc-99m-MAA) is well established in the diagnostic of pulmonary embolism (PE). In the last decade, it was shown that single-photon emission computer tomography (SPECT) acquisition of LPS overcame static scintigraphy. Furthermore, there are rare indications for LPS, such as preoperative quantification of regional lung function prior to lung resection or transplantation, optimization of lung cancer radiation therapy, quantification of right-left shunt, planning of intra-arterial chemotherapy, and several rare indications in pediatrics. Moreover, LPS with Tc-99m-MAA is a safe method with low radiation exposure. PE can also be diagnosed by spiral computer tomography (CT), ultrasound, magnetic resonance angiography, or pulmonary angiography (PA, former gold standard). The present review considers all these methods, especially spiral CT, and compares them with LPS with respect to sensitivity and specificity and gives an overview of established and newer publications. It shows that LPS with Tc-99m-MAA represents a diagnostic method of continuing value for PE. In comparison with spiral CT and/or PA, LPS is not to be defeated as mentioned also by the most actual Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) II reports. This applies in particular to chronic or recurring embolisms, whereas currently spiral CT may be of greater value for major or life-threatening embolisms. At present, LPS cannot be replaced by other methods in some applications, such as pediatrics or in the quantification of regional pulmonary function in a preoperative context or prior to radiation therapy. LPS still has a place in the diagnostics of PE and is irreplaceable in several rare indications as described earlier.

Abstract
BACKGROUND AND PURPOSE Pulmonary embolism (PE) represents a real diagnostic challenge. PE is associated with pulmonary hypertension due to pulmonary vascular obstruction and vasoconstriction. We recently reported that pulmonary gas embolism transiently increases exhaled nitric oxide (FENO), but it is not known whether solid emboli may alter FENO, and whether an intact endogenous NO synthesis has a beneficial effect in experimental solid pulmonary embolism. EXPERIMENTAL APPROACH We used anaesthetised and ventilated rabbits in these experiments. To mimic PE, a single intravenous infusion of homogenized autologous skeletal muscle tissue (MPE) was given to rabbits with intact NO production (MPE of 60, 15, or 7.5 mg kg(-1); group 1) and to another group (group 2) with inhibited NO synthesis (L-NAME 30 mg kg(-1); MPE of 7.5, 15 or 30 mg kg(-1)). KEY RESULTS In group 1, after MPE, FENO increased rapidly and dose-dependently and FENO was still significantly elevated after 60 min with the two highest emboli doses. All these animals survived more than 60 min after embolization. In group 2, MPE of 7.5, 15 and 30 mg kg(-1), in combination with NO synthesis inhibition, resulted in 67%, 50% and 25% survival at 60 min respectively, representing a statistically significant decrease in survival. Cardiovascular and blood-gas changes after MPE were intensified by pre-treatment with NO synthesis inhibitor. CONCLUSIONS AND IMPLICATIONS We conclude that solid PE causes a sustained, dose-dependent increase in FENO, giving FENO a diagnostic potential in PE. Furthermore, intact NO production appears critical for tolerance to acute PE.

Diagnostic value of D-dimer in patients with suspected pulmonary embolism: results from a multicentre outcome study. Thromb Res 2006; 120:195-200.

Abstract
BACKGROUND D-dimer tests are used in various diagnostic strategies to exclude pulmonary embolism (PE). However, their role as an exclusionary first-line test is still uncertain, mainly because accuracy of the test varies according to the assay and the studied population. METHODS The aim of this multicentre study was to evaluate the accuracy of D-dimer testing in patients with suspected PE. Diagnosis of PE was based on pre-test clinical probability (PCP) evaluation and both single-detector spiral CT (CT) and lower limbs compression ultrasonography (CUS). Lung scanning and/or pulmonary angiography was mandatory when CT or CUS was inconclusive and when both CT and CUS were normal in a patient with a high PCP. All patients were followed-up for 3 months, looking for VTE recurrence. D-dimers were collected within 24 h of inclusion and stored in each local hematology unit, to be analyzed at the end of all inclusions; physicians in charge of the patient were blinded to D-dimer results. RESULTS Three hundred and fifty two patients were included in 4 centres. Prevalence of PE was 38.6%. PCP was low in 82 (23.3%), intermediate in 176 (50%) and high in 94 (26.7%) patients. Sensitivity of D-dimer was 96.3% (95% CI: 93-99) and negative predictive value reached 94.4% (95% CI: 90-99). Five patients with a confirmed PE had a D-dimer level below 500 ng/ml (two patients with a high PCP). Among 258 patients with low or intermediate PCP, 80 (31%) had a negative D-dimer test result; three of them had a false negative result and the number needed to test was 3.3. Among 94 patients with a high PCP, 9 had a negative D-dimer test result; two of them had a false negative result and the number needed to test was 13.5. CONCLUSION These results confirm that rapid assays used in this study can safely exclude PE in first-line testing only in non-high CP patients.

Abstract
Syncope as an initial presentation of pulmonary embolism occurs in 10% of patients. We compared clinical and instrumental parameters in patients with syncope as the presenting symptom of pulmonary embolism and in patients with documented pulmonary embolism without syncope. Seventy patients with the diagnosis of pulmonary embolism and apparently stable clinical conditions were evaluated. They were divided in two groups: 10 patients with syncope as the presenting symptom of pulmonary embolism (group 1) and 60 patients without syncope (group 2). Patients with syncope showed a more pronounced tendency to present with main pulmonary artery embolus than patients without syncope (contingency coefficient = 0.301, p < 0.04; one-tailed). However, despite the evidence that patients with syncope have significant reductions in systolic and/or diastolic blood pressure, shock was not observed in any patient. In no case was thrombolytic treatment given and all patients received standard anticoagulation with unfractioned heparin and oral anticoagulant. We suggest that syncope in the setting of non-massive pulmonary embolism may be due to vaso-vagal mechanism that can lead to a reduction of arterial blood pressure when central artery thrombosis is involved.
