Abstract
The inability to obtain or maintain a secure seal between a vessel wall and a transluminally implanted intra-aneurysmal graft is a complication unique to the evolving technique of endovascular aneurysm exclusion. Because the term “leak” has long been associated with aneurysm rupture, the term “endoleak” is proposed as a more definitive description of this phenomenon. Embracing both persistent blood flow into the aneurysmal sac from within or around the graft (graft related) and from patent collateral arteries (nongraft related), endoleak can be classified as primary or secondary depending on the time of occurrence (within 30 days of implantation or following apparent initial seal, respectively). Diagnostic techniques to detect endoleak include arteriography, intraprocedural pressure monitoring, contrast-enhanced computed tomography, abdominal X ray, and duplex scanning. Management strategies for endoleak range from observation with periodic imaging surveillance to correction by additional endoluminal or surgical procedures. Standardization of the terminology describing this important sequela to endovascular aneurysm exclusion should facilitate uniform reporting of clinical trial data vital to the evaluation of this emerging technique.

Abstract
PURPOSE Anatomical variations of pulmonary veins, even though not rare, have important role, especially in patients undergoing lung surgery. We present a case of a single common pulmonary venous drainage of the left upper and lower lobe of the lung. METHOD/RESULT The common trunk of the left superior and inferior pulmonary vein was misidentified as an inferior pulmonary vein, and it was transected during surgery. CONCLUSION The surgeon must always be aware of this anomaly and carefully verify the normal anatomical structures before dividing them while performing an upper or lower lobectomy.

Abstract
BACKGROUND Aneurysmal rebleed is the most dreaded complication following subarachnoid hemorrhage. Being a cause of devastating outcome, the stratification of risk factors can be used to prioritize patients, especially at high volume centers. METHOD A total of 99 patients with aneurysmal rebleed were analyzed in this study both prospectively and retrospectively from August 2010 to July 2014. In the control group, 100 patients were selected randomly from the patient registry. A total of 25 variables from the demographic, historical, clinical and radiological data were compared and analyzed by univariate and multivariate logistic regression analysis. RESULTS Significant independent predictors of aneurysm rebleed were the presence of known hypertension (p = 0.023), diastolic blood pressure of >90 mmHg on admission (p = 0.008); presence of loss of consciousness (p = 0.013) or seizures (p = 0.002) at first ictus; history of warning headaches (p = 0.005); higher Fisher grade (p < 0.001); presence of multiple aneurysms (p = 0.021); irregular aneurysm surface (0.002). CONCLUSIONS Identification of high risk factors can help in stratifying patients in the high risk group. The risk stratification strategy with early intervention can prevent rebleeds. This in turn may translate into better outcomes of patients with intracranial aneurysms.

Abstract
Objective: To determine whether hydrogen peroxide (H2O2) mouthwash influences the outcome of secondary post-tonsillectomy hemorrhage in children. Study Design: Ten-year retrospective study of all children with secondary post-tonsillectomy hemorrhage. Setting: Tertiary otolaryngology center. Results: Of the 156 patients, 59 received H2O2 and 97 did not. All patients received broad-spectrum intravenous antibiotics. The average rehospitalization duration due to hemorrhage was 1.7 days (H2O2 group) and 1.6 days (control group). In the H2O2 group, 8.5% required surgery, compared with 10.3% in the control group. Further hemorrhage episodes requiring readmission occurred in 3.4% of the H2O2 group and 3.1% of controls. There was no difference between the 2 groups in rehospitalization duration ( P = 0.49), rate of surgical intervention ( P = 0.85), and rate of readmission with further hemorrhage ( P = 0.92). Conclusion: Hydrogen peroxide mouthwash does not improve the outcome of secondary post-tonsillectomy hemorrhage in pediatric patients. Significance: This study does not support the common practice of treating post-tonsillectomy hemorrhage with H2O2.

Abstract
PURPOSE To evaluate whether intra-abdominal hemorrhage is visible on a modified focused assessment with sonography for trauma (FAST) examination in stable obstetrics patients after a nonemergent cesarean delivery. METHODS This was a prospective observational study of patients who underwent nonemergent cesarean delivery at a single institution. Patients provided written informed consent to participate in the study preoperatively and underwent a modified FAST examination in the recovery room within 2 hours of completion of surgery. A sonographic examination was considered positive for hemorrhage if an anechoic pocket consistent with free fluid was present. RESULTS One hundred patients underwent suprapubic and bilateral upper-quadrant sonographic evaluations. The mean (±SD) time of the evaluation was 74.2 ± 36 minutes after the end of surgery. Among the 100 sonographic examinations of each upper quadrant, 194 (97.0%) were negative, 5 (2.5%) were indeterminate, and 1 (0.5%) was positive for fluid. All suprapubic sonographic examinations were considered inadequate. CONCLUSIONS Sonographic evaluation immediately after cesarean delivery is feasible in most patients and was overwhelmingly negative for intra-abdominal hemorrhage in a group of patients who did not require reoperation or unexpected blood transfusion.

Abstract
OBJECTIVES Evacuation of shed blood from around the heart and lungs is a critical requirement for patients in early recovery after cardiac surgery. Incomplete evacuation of shed blood can result in retained blood, which may require subsequent reinterventions to facilitate recovery. The purpose of this study was to determine the incidence of retained blood requiring reintervention and examine the impact on outcomes. METHODS We performed a cross-sectional, observational study of all adult patients undergoing cardiac surgery between 2006 and 2013. Subjects who required an intervention to remove blood, blood clot, or bloodily fluid were attributed to the retained blood group. These patients were compared with those not presenting with any of the defined criteria for retained blood. Multivariate regression was performed to account for confounders. RESULTS Of 6909 adult patients who underwent cardiac surgery, 1316 (19%) presented with a retained blood-related condition. Retained blood was associated with increased in-hospital mortality (odds ratio [OR], 4.041; 95% confidence interval [CI], 2.589-6.351, P < .001) and a length of stay more than 13 days in the hospital (OR, 3.853; 95% CI, 2.882-5.206; P < .001) and 5 days in the intensive care unit (OR, 4.602; 95% CI, 3.449-6.183; P < .001). The OR for a time of ventilation greater than 23 hours was 3.596 (95% CI, 2.690-4.851; P < .001) and for incidence of renal replacement therapy was 4.449 (95% CI, 3.188-6.226; P < .001). CONCLUSIONS Postoperative retained blood is a common outcome and associated with higher in-hospital mortality, longer intensive care unit and hospital stay, and higher incidence of renal replacement therapy. Further research is needed to validate these results and explore interventions to reduce these complications.

Abstract
AIM: To predict the re-bleeding after endoscopic hemostasis for delayed post-endoscopic sphincterotomy (ES) bleeding.
METHODS: Over a 15-year period, data from 161 patients with delayed post-ES bleeding were retrospectively collected from a single medical center. To identify risk factors for re-bleeding after initial successful endoscopic hemostasis, parameters before, during and after the procedure of endoscopic retrograde cholangiopancreatography were analyzed. These included age, gender, blood biochemistry, co-morbidities, endoscopic diagnosis, presence of peri-ampullary diverticulum, occurrence of immediate post-ES bleeding, use of needle knife precut sphincterotomy, severity of delayed bleeding, endoscopic features on delayed bleeding, and type of endoscopic therapy.
RESULTS: A total of 35 patients (21.7%) had re-bleeding after initial successful endoscopic hemostasis for delayed post-ES bleeding. Univariate analysis revealed that malignant biliary stricture, serum bilirubin level of greater than 10 mg/dL, initial bleeding severity, and bleeding diathesis were significant predictors of re-bleeding. By multivariate analysis, serum bilirubin level of greater than 10 mg/dL and initial bleeding severity remained significant predictors. Re-bleeding was controlled by endoscopic therapy in a single (n = 23) or multiple (range, 2-7; n = 6) sessions in 29 of the 35 patients (82.9%). Four patients required transarterial embolization and one went for surgery. These five patients had severe bleeding when delayed post-ES bleeding occurred. One patient with decompensated liver cirrhosis died from re-bleeding.
CONCLUSION: Re-bleeding occurs in approximately one-fifth of patients after initial successful endoscopic hemostasis for delayed post-ES bleeding. Severity of initial bleeding and serum bilirubin level of greater than 10 mg/dL are predictors of re-bleeding.

Abstract
BACKGROUND Femoral artery closure device use following percutaneous cannulation allows earlier mobilization, reduced staff burden, and improved comfort for patients compared with manual compression. The Mynx device (Access Closure, Inc), a novel extravascular closure device, uses a water-soluble non-thrombogenic polyethylene glycol plug. METHODS We report retrospective analysis of success, complication rates, and associated factors in 432 consecutive patients undergoing elective outpatient coronary angiography in a single United Kingdom center. RESULTS Six Fr sheaths were used in 62.1% and 5 Fr sheaths were used in 37.8%, with 100% successful deployment using a Mynx device. A total of 57.5% of patients were male. In 79.4%, this was the first procedure requiring femoral arteriotomy, while 20.6% had a previous procedure. Overall, 3.2% required conversion to manual compression/ FemoStop (St. Jude Medical) due to impending hematoma. In all, 99.5% of patients were discharged on the same day. Confirmed hematoma >5 cm was noted in 0.7% patients, with only 2 patients (0.5%) reporting "any discomfort" during deployment and the same requiring overnight hospitalization. Use of a 6 Fr sheath (compared with 5 Fr) was associated with conversion to manual compression and complications (P<.05), as was valvular heart disease as the indication for angiography (P<.05). Hematoma formation was associated with higher diastolic and mean arterial pressure (107.4 mm Hg vs 99.6 mm Hg; P<.01). There was no increase in complications associated with use of antiplatelet/anticoagulants, previous stroke, myocardial infarction/ischemic heart disease, peripheral vascular disease, diabetes, high body mass index, or previous angiographic procedure. CONCLUSIONS Postangiography use of the Mynx closure device is highly successful, safe, and well-tolerated with a low complication rate, allowing safe same-day discharge.

Abstract
Perioperative transfusion of blood products is associated with increased morbidity and mortality after pediatric cardiac surgery. We report the results of a quality improvement project aimed at decreasing perioperative blood product administration and bleeding after pediatric cardiopulmonary bypass (CPB) surgery. A multidisciplinary team evaluated baseline data from 99 consecutive CPB patients, focusing on the variability in transfusion management and bleeding outcomes, to create a standardized bleeding and transfusion management protocol. A total of 62 subsequent patients were evaluated after implementation of the protocol: 17 with single pass hemoconcentrated (SPHC) blood transfusion and 45 with modified ultrafiltration (MUF). Implementation of the protocol with SPHC blood led to significant decrease in transfusion of every blood product in the cardiovascular operating room and first 6 hours in cardiovascular intensive care unit ([CVICU] p < .05). Addition of MUF to the protocol led to further decrease in transfusion of all blood products compared to preprotocol. Patients <2 months old had 49% decrease in total blood product administration: 155 mL/kg preprotocol, 117 mL/kg protocol plus SPHC, and 79 mL/kg protocol plus MUF (p < .01). There were significant decreases in postoperative bleeding in the first hour after CVICU admission: 6 mL/kg preprotocol, 3.8 mL/kg protocol plus SPHC, and 2 mL/kg protocol plusMUF (p = .02). There was also significantly decreased incidence of severe postoperative bleeding (>10 mL/kg) in the first CVICU hour for protocol plus MUF patients (p < .01). Implementation of a multidisciplinary bleeding and transfusion protocol significantly decreases perioperative blood product transfusion and improves some bleeding outcomes.

Abstract
BACKGROUND Postsurgical bleeding causes significant morbidity and mortality in children undergoing surgery for congenital heart defects (CHD). 22q11.2 deletion syndrome (DS) is the second most common genetic risk factor for CHD. The deleted segment of chromosome 22q11.2 encompasses the gene encoding glycoprotein (GP) Ibβ, which is required for expression of the GPIb-V-IX complex on the platelet surface, where it functions as the receptor for von Willebrand factor (VWF). Binding of GPIb-V-IX to VWF is important for platelets to initiate hemostasis. It is not known whether hemizygosity for the gene encoding GPIbβ increases the risk for bleeding following cardiac surgery for patients with 22q11.2 DS. METHODS We performed a case-control study of 91 pediatric patients who underwent cardiac surgery with cardiopulmonary bypass from 2004 to 2012 at Children's Hospital of Wisconsin. RESULTS Patients with 22q11.2 DS had larger platelets and lower platelet counts, bled more excessively, and received more transfusion support with packed red blood cells in the early postoperative period relative to control patients. CONCLUSION Presurgical genetic testing for 22q11.2 DS may help to identify a subset of pediatric cardiac surgery patients who are at increased risk for excessive bleeding and who may require more transfusion support in the postoperative period.

Abstract
BACKGROUND DATA The use of surgical drains after traditional splenectomy has been largely debated and several Authors have been unfavorable to their use. With the advent of laparoscopic splenectomy, their role has been re-discussed. The increased risk of undetectable pancreatic, gastric or colon injury in challenging laparoscopic removal of the spleen have induced some surgeons to reconsider the advantages related to their use. METHODS One hundred seventeen consecutive cases of laparoscopic splenectomy with routine use of surgical drains have been reviewed. Indications for surgery, length of operations, post-operative day of drain removal, post-operative complications were retrospectively analyzed. RESULTS Laparoscopic splenectomy was performed for idiopathic thrombocytopenic purpura in 77 patients (65,8%), splenic lymphoma in 11 (9,4%), hereditary spherocytosis in 12 (10,2%), β-thalassemia in 6 (5.1%), other diseases in 11 (9,4%) cases. Conversion to open surgery was necessary in 11,1% of cases. Drains were removed 2-3 days after surgery in 95,8%, within 10 days in 3.4%, within 2 months in 0,8% of cases. In 2 cases a post-operative bleeding, detected through the drainage, required re-operation. One patient with myelofibrosis and massive splenomegaly developed a late post-operative subphrenic abscess, successfully treated by a percutaneous drainage. CONCLUSIONS In Authors' experience, the use of drains after laparoscopic splenectomy helped detect early post-operative bleeding. Surgical drains could reduce the incidence of fluid intra-abdominal collections and infections. Their use should be recommended in the laparoscopic approach, especially in technically demanding surgical procedures. KEY WORDS Laparoscopy, Surgical drainage, Splenectomy.

Abstract
AIM To define the role of endoscopic hemostasis in treatment of gastroduodenal ulcers complicated by bleeding. MATERIAL AND METHODS The results of endoscopic hemostasis in 770 patients with peptic ulcers were analyzed. RESULTS Injection hemostasis had the highest efficacy in case of recurrent bleeding. No other method showed significant advantage in its efficiency. The efficacy of injection method was 52%, argon-plasma coagulation - 83.3%, radiowave technique - 78%, combined endoscopic method - 96%. In case of recurrent bleeding endoscopic hemostasis is effective alternative to surgery especially in high-risk patients. Repeated endoscopic hemostasis significantly decreases mortality from 45% to 23% in case of recurrent bleeding.

Abstract
BACKGROUND Revascularization of calcified coronary lesions has been shown to be associated with suboptimal outcomes. The optimal revascularization strategy for calcified lesions in patients presenting with non-ST segment elevation acute coronary syndromes (NSTEACS) has yet to be defined. METHODS Outcomes in patients presenting with NSTEACS and moderately or severely calcified target lesions in native coronary vessels, as assessed by an independent angiographic core lab, were examined according to revascularization strategy (percutaneous coronary intervention [PCI] vs coronary artery bypass graft [CABG] surgery) from the large-scale, prospective ACUITY trial. Propensity-adjusted multivariable analysis was used to identify the independent predictors of events at 30 days. RESULTS Of 1315 NSTEACS patients with moderately and severely calcified lesions in whom revascularization was performed, a total of 334 (25%) and 981 (75%) underwent CABG and PCI, respectively. CABG patients had more severe baseline comorbidities and coronary artery disease. By propensity-adjusted multivariable analysis, the CABG group had higher 30-day rates of reinfarction, composite death or reinfarction, major bleeding, and thrombocytopenia. CONCLUSIONS In this large-scale study of patients presenting for NSTEACS, 30-day adverse events were more frequent after revascularization of calcified coronary lesions with CABG rather than PCI. Further studies are warranted to evaluate means of improving early safety outcomes in this high-risk patient group with complex coronary disease.

Abstract
BACKGROUND AND STUDY AIM High quality colonoscopy requires low complication rates. However in quality assurance, evaluation of individual colonoscopist complication rates is limited because complications are relatively rare events and there is variation in average procedure complexity. The aim of the study was to develop a quality system that adjusted for procedure complexity to monitor bleeding adverse events at both the screening center and colonoscopist levels. METHODS The study examined the risk factors for post-procedure bleeding from 130 831 colonoscopies conducted between August 2006 and January 2012. Binomial and logistic regression models were used to examine the risk of events against explanatory variables including age, sex, polyps resected, and polyp size. The models were used to produce a procedure-adjusted standardized adverse event ratio (PASAER) based on the ratio of the observed to expected number of adverse events. The primary outcome of interest was to identify centers that were outside a funnel plot outlier level of 99.8 % (3 SDs). RESULTS Mulivariate models showed that the risk of bleeding was associated with largest resected polyp size, sex, polyp location, and degree of co-morbidity. These variables were used to calculate PASAERs for the 59 screening centers and 286 colonoscopists. The method highlighted one center with a high PASAER of 3.08 (32 observed compared with 10.4 expected events) and one with a low PASAER of 0.34 (10 observed compared with 29.8 expected events), which merited further investigation. CONCLUSIONS The PASAER provided additional certainty that a crude adverse event rate was not confounded by procedure complexity, thus objectively identifying centers or colonoscopists that required further performance evaluation.

Abstract
BACKGROUND Excessive postoperative blood loss after cardiopulmonary bypass is a common problem, especially in patients suffering from congenital heart diseases. The efficacy of epsilon aminocaproic acid (EACA) as a prophylactic treatment for postoperative bleeding after pediatric open-heart surgery has not been determined. This meta-analysis investigates the efficacy of EACA in the minimization of bleeding and blood transfusion and the maintenance of coagulation tests after pediatric open-heart surgery. METHODS A comprehensive literature search was performed to identify all randomized clinical trials on the subject. PubMed, Embase, the Cochrane Library, and the Chinese Medical Journal Network were screened. The primary outcome used for the analysis was postoperative blood loss. Secondary outcomes included postoperative blood transfusion, re-exploration rate and postoperative coagulation tests. The mean difference (MD) and risk ratio (RR) with 95% confidence intervals (CI) were used as summary statistics. RESULTS Five trials were included in this meta-analysis of 515 patients. Prophylactic EACA was associated with a reduction in postoperative blood loss, but this difference did not reach statistical significance (MD: -7.08; 95% CI: -16.11 to 1.95; P = 0.12). Patients treated with EACA received fewer postoperative blood transfusions, including packed red blood cells (MD: -8.36; 95% CI: -12.63 to -4.09; P = 0.0001), fresh frozen plasma (MD: -3.85; 95% CI: -5.63 to -2.08; P < 0.0001), and platelet concentrate (MD: -10.66; 95% CI: -18.45 to -2.87; P = 0.007), and had a lower re-exploration rate (RR: 0.46; 95% CI: 0.23 to 0.92; P = 0.03). Prophylactic EACA also improved coagulation tests 6 hours after open-heart surgery. CONCLUSIONS Prophylactic EACA minimizes postoperative blood transfusion and helps maintain coagulation in pediatric patients undergoing open-heart surgery. Therefore, the results of this study indicate that adjunctive EACA is a good choice for the prevention of postoperative blood transfusion following pediatric cardiac surgery.

Abstract
Teledermatology via patient-generated digital images or "selfies" has been increasing since the advent of portable devices capable of high resolution image capture. During these early days, doctors and patients are learning about uses and limitations. We describe a case in which a patient's selfie led three attending physicians to suspect an iatrogenic hematoma requiring urgent assessment. There was no hematoma at follow up, simply dark and smooth adherent crust, which was gently removed to reveal a well-healing wound. This case introduces a previously undescribed teledermatology-related issue, that of "overcalling" a selfie. An image supplied by a patient misleadingly appeared to show a serious complication requiring urgent treatment.

Abstract
We herein report a case of bronchial bleeding after radical esophagectomy that was treated with lobectomy. A 65-year-old male who underwent subtotal esophagectomy with three-field lymph node dissection for esophageal carcinoma was referred to our hospital because of sudden hemoptysis. After the esophagectomy, bilateral vocal cord paralysis was observed, and the patient suffered from repeated episodes of aspiration pneumonia. Bronchoscopy revealed hemosputum in the right middle lobe bronchus, and contrast-enhanced computed tomography showed tortuous arteries arising from the right inferior phrenic artery and left subclavian artery toward the right middle lobe bronchus. Although bronchial arterial embolization was performed twice to control the recurrent hemoptysis, the procedures were unsuccessful. Right middle lobectomy was therefore performed via video-assisted thoracic surgery. Engorged bronchial arterys with medial hypertrophy and overgrowth of the small branches were noted near the bronchus in the resected specimen. The patient recovered uneventfully and was discharged on postoperative day 14.

Abstract
BACKGROUND The need to obtain successful surgical hemostasis had a significant impact on the development of electrosurgery. Innovative technical solutions necessitate the continuous training of surgeons in the use of more modern technologies. The diversity of solutions is also associated with the need to adapt the methods for obtaining hemostasis to the type of operation. Each time, the introduction of new technologies requires a critical evaluation of the results of surgical treatment. The most important measure of quality in thyroid surgery is the presence of chronic complications, such as the recurrent laryngeal nerve palsy and parathyroid insufficiency. Transient disorders also have a significant impact on the patient's comfort and quality of life. The report is preliminary in nature and it requires further investigation. OBJECTIVES The aim of the study was to evaluate the effect of three methods for obtaining hemostasis on the occurrence of hypoparathyroidism, recurrent laryngeal nerve palsy, bleeding and the surgical site infection after thyroid surgery. MATERIAL AND METHODS A retrospective analysis included patients who underwent thyroidectomy (n=654). Three methods of hemostasis were used. The first group (n=339) had blood vessels tied off. In the second (n=192) bipolar electrocoagulation was used and in the third one (n=123) bipolar electrocoagulation with integrated cutting mechanism. RESULTS The transient hypoparathyroidism was found in 1.4% patients in the first group, 8.3% in the second and 27.6% in the third one. Chronic hypoparathyroidism was found in 0.29% in the first group, 0% in the second group and 2.4% in the third group. Significantly statistical differences were found in the incidence of transient hypoparathyroidism. CONCLUSIONS Significant statistical differences were found in incidences of transient hypoparthyroidism in the group where bipolar electrosurgery was used.

Abstract
AIMS Vascular closure device (VCD)-based venous closure has been anecdotally reported, but systematic evaluation of the reparative response of the vessel wall to venous closure is lacking. The need to control groin complications, and minimize risks associated with postponed sheath removal under conditions of persistent anticoagulation, has generated interest in the role of VCDs for venous access closure. We sought to characterize the vessel wall response to venous closure, both acutely and in delayed fashion at 30 days using angiography, ultrasound, and histology. METHODS Ten venous 7 Fr sheaths were deployed in the femoral veins of swine. Bilateral venous access sites were subsequently closed utilizing manual compression (MC; control arm: n = 4) or a closure device utilizing an extravascular polyethylene glycol sealant (MynxGrip treatment arm: n = 6). Acute (post closure), 3-day, and 30-day vascular ultrasound, as well as venography (internal jugular approach) were used to assess outcomes. Gross pathology and histology were obtained at the 30-day endpoint for all femoral venous closure sites. RESULTS Hemostasis was successfully achieved in all cases without access-site complications. Venography and ultrasound confirmed normal ilio-femoral anatomy and flow at all study time points. Gross pathology and histopathology revealed no evidence of deep vein thrombosis, and no abnormalities were seen in the vena cava, heart, or lungs. Histology at 30 days showed complete healing of the vein wall access site, with a small focus of chronic inflammation and fibrosis in the perivascular adventitial tissue of the access tract. There was no microscopic evidence of the sealant. The tissue tract showed mild discrete inflammation (foamy macrophages, lymphocytes, plasma cells) with microgranulomas centered on residual red cells in both treatment and control groups. CONCLUSIONS This study characterizes the angiographic, ultrasound, and histopathology outcomes of femoral vein closure, and provides insight into the healing mechanisms following venotomy. The bio-resorptive role of MynxGrip extravascular sealant in achieving effective venous closure and preserved long-term vessel patency without venous thromboembolism is demonstrated.

Abstract
BACKGROUND Cardiac tamponade, due to bleeding in the pericardial space after esophagectomy for esophageal cancer, is an extremely rare complication and may be associated with sudden hemodynamic instability that can lead to death unless there is prompt diagnosis and appropriate treatment. CASE REPORT A 76-year-old man underwent sub-total esophagectomy via a cervico-right thoracoabdominal approach and reconstruction with a gastric tube through the retrosternal route. On postoperative day 4, the patient developed hypotension due to cardiac tamponade caused by bleeding into the pericardial space and he had a decreased level of consciousness. Pericardial resection and open drainage via a minimal left anterior thoracotomy was performed that resulted in hemodynamic improvement followed by an uneventful recovery. CONCLUSION Cardiac tamponade due to postoperative bleeding, which is a rare but life-threatening complication, should be considered as a cause of hemodynamic instability in the early postoperative period after esophagectomy.

Abstract
Impaired haemostasis represents a major risk factor for bleeding complications in neurosurgical patients. Coagulopathy commonly occurs after (brain) trauma and major haemorrhage or originates from antithrombotic medication. Point of care (POC) devices for bedside assessment of haemostatic parameters are increasingly used in various medical specialties. Results can be instantly implemented into treatment modalities as results are delivered within a very short period. POC coagulation testing has also shown beneficial effects in the treatment of neurosurgical patients. Identification of hyperfibrinolysis is achieved through viscoelastic testing of haemostasis and bedside coagulometry hastens the management of anticoagulated patients in need of urgent neurosurgical procedures. Results of POC testing of platelet function have been correlated with patient outcomes after traumatic brain injury and furthermore, quantification of antiplatelet medication effects on platelet activity is made possible through the use of these devices. Further studies are needed to characterise the potential of POC testing of platelet function. Antiplatelet medication plays an important role in regard to haemorrhagic and thromboembolic risks. Therefore, POC testing of platelet activity may improve treatment modalities in patients undergoing neurosurgical procedures as well as neurointerventional procedures (such as intracranial stent placement). In this article we summarise the available data of POC testing in neurosurgical patients and discuss the potential of these devices in this field. POC technologies have improved patient care in various medical fields and in our view it is likely that this will also apply to the field of neurosurgery.
