Comparison of interventions for intermediate to high-risk pulmonary embolism: A network meta-analysis. Catheter Cardiovasc Interv 2023. [PMID: 37269229 DOI: 10.1002/ccd.30745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 05/20/2023] [Indexed: 06/05/2023]
Abstract
BACKGROUND Multiple interventions, including catheter-directed therapy (CDT), systemic thrombolysis (ST), surgical embolectomy (SE), and therapeutic anticoagulation (AC) have been used to treat intermediate to high-risk pulmonary embolism (PE), but the most effective and safest treatment remains unclear. Our study aimed to investigate the efficacy and safety outcomes of each intervention. METHODS We queried PubMed and EMBASE in January 2023 and performed a network meta-analysis of observational studies and randomized controlled trials (RCT), including high or intermediate-risk PE patients, and comparing AC, CDT, SE, and ST. The primary outcomes were in-hospital mortality and major bleeding. The secondary outcomes included long-term mortality (≥6 months), recurrent PE, minor bleeding, and intracranial hemorrhage. RESULTS We identified 11 RCTs and 42 observational studies involving 157,454 patients. CDT was associated with lower in-hospital mortality than ST (odds ratio [OR] [95% confidence interval (CI)]: 0.41 [0.31-0.55]), AC (OR [95% CI]: 0.33 [0.20-0.53]), and SE (OR [95% CI]: 0.61 [0.39-0.96]). Recurrent PE in CDT was lower than ST (OR [95% CI]: 0.66 [0.50-0.87]), AC (OR [95% CI]: 0.36 [0.20-0.66]), and trended lower than SE (OR [95% CI]: 0.71 [0.40-1.26]). Notably, ST had higher major bleeding risks than CDT (OR [95% CI]: 1.51 [1.19-1.91]) and AC (OR [95% CI]: 2.21 [1.53-3.19]). By rankogram analysis, CDT presented the highest p-score in in-hospital mortality, long-term mortality, and recurrent PE. CONCLUSION In this network meta-analysis of observational studies and RCTs involving patients with intermediate to high-risk PE, CDT was associated with improved mortality outcomes compared to other therapies, without significant additional bleeding risk.

Clinical characteristics and treatment of patients with central pulmonary embolism and right heart thrombus. Echocardiography 2023. [PMID: 37212381 DOI: 10.1111/echo.15592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 04/24/2023] [Accepted: 05/02/2023] [Indexed: 05/23/2023] Open
Abstract
INTRODUCTION Right heart thrombus (RHT), also known as clot in transit, is an uncommon finding in pulmonary embolism (PE) that is associated with increased inpatient mortality. To date, there is no consensus on the management of RHT. Therefore, we aim to describe the clinical features, treatments, and outcomes of patients with simultaneous RHT and PE. METHODS This is a retrospective, cross-sectional, and single-center study of hospitalized patients with central PE who had RHT visualized on transthoracic echocardiography (TTE) from January 2012 to May 2022. We use descriptive statistics to describe their clinical features, treatments, and outcomes, including mechanical ventilation, major bleeding, inpatient mortality, length of hospital stay, and recurrent PE on follow-up. RESULTS Of 433 patients with central PE who underwent TTE, nine patients (2%) had RHT. The median age was 63 years (range 29-87), most were African American (6/9), and females (5/9). All patients had evidence of RV dysfunction and received therapeutic anticoagulation. Eight patients received RHT-directed interventions, including systemic thrombolysis (2/9), catheter-directed suction embolectomy (4/9), and surgical embolectomy (2/9). Regarding outcomes, 4/9 patients were hemodynamically unstable, 8/9 were hypoxemic, and 2/9 were mechanically ventilated. The median length of hospital stay was six days (range 1-16). One patient died during hospital admission, and two patients had recurrent PE. CONCLUSION We described the different therapeutic approaches and outcomes of patients with RHT treated in our institution. Our study adds valuable information to the literature, as there is no consensus on the treatment of RHT. HIGHLIGHTS Right heart thrombus (RHT) was a rare finding in central pulmonary embolism. Most patients with RHT had evidence of RV dysfunction and pulmonary hypertension. Most patients received RHT-directed therapies in addition to therapeutic anticoagulation.

Barriers and facilitators to interhospital transfer of acute pulmonary embolism: An inductive qualitative analysis. Front Med (Lausanne) 2023; 10:1080342. [PMID: 36936238 PMCID: PMC10014587 DOI: 10.3389/fmed.2023.1080342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 02/10/2023] [Indexed: 03/05/2023] Open
Abstract
Background Interhospital transfer (IHT) of patients with acute life-threatening pulmonary embolism (PE) is necessary to facilitate specialized care and access to advanced therapies. Our goal was to understand what barriers and facilitators may exist during this transfer process from the perspective of both receiving and referring physicians. Methods This qualitative descriptive study explored physician experience taking care of patients with life threatening PE. Subject matter expert physicians across several different specialties from academic and community United States hospitals participated in qualitative semi-structured interviews. Interview transcripts were subsequently analyzed using inductive qualitative description approach. Results Four major themes were identified as barriers that impede IHT among patients with life threatening PE. Inefficient communication which mainly pertained to difficulty when multiple points of contact were required to complete a transfer. Subjectivity in the indication for transfer which highlighted the importance of physicians understanding how to use standardized risk stratification tools and to properly triage these patients. Delays in data acquisition were identified in regards to both obtaining clinical information and imaging in a timely fashion. Operation barriers which included difficulty finding available beds for transfer and poor weather conditions inhibiting transportation. In contrast, two main facilitators to transfer were identified: good communication and reliance on colleagues and dedicated team for transferring and treating PE patients. Conclusion The most prominent themes identified as barriers to IHT for patients with acute life-threatening PE were: (1) inefficient communication, (2) subjectivity in the indication for transfer, (3) delays in data acquisition (imaging or clinical), and (4) operational barriers. Themes identified as facilitators that enable the transfer of patients were: (1) good communication and (2) a dedicated transfer team. The themes presented in our study are useful in identifying opportunities to optimize the IHT of patients with acute PE and improve patient care. These opportunities include instituting educational programs, streamlining the transfer process, and formulating a consensus statement to serve as a guideline regarding IHT of patients with acute PE.

Abstract
Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is currently known to lead to high rates of thrombotic complications. Of those, acute limb ischemia (ALI) was most frequently reported. Several case reports or case series had already described high mortality and amputation rates. The purpose of our study was to highlight the epidemiological, clinical, and management characteristics of coronavirus disease 2019 (COVID-19)-related ALI patients. Methods This was a monocentric, observational, and retrospective study. Records of all patients ≥18 years of age admitted with ALI and a confirmed diagnosis of COVID-19 infection between March 2020 and December 2021 were retrospectively examined. Data collected included demographics, co-morbidities, biological findings, COVID-19 pneumonia and ALI severity, anatomical location of arterial thromboembolism, treatments, and outcomes. Results During the study period, 22 patients with ALI infected with COVID-19 were evaluated. The median age was 67 years (45-88) and 18 (81.8%) were men. The main comorbidities were diabetes mellitus (36.4%), smoking (22.7%), and arterial hypertension (18.2%). All 22 patients were already diagnosed positive for SARS-CoV-2. The median duration between COVID-19 diagnosis and ALI symptom onset was six days (1-13 days). The computed tomography (CT) extent of pulmonary lesions was assessed according to the French Society of Chest Imaging. The ischemic syndrome was classified on Rutherford Stage IIA (30.4%) and IIB (43.5%). Regarding thrombotic locations, ALI had occurred essentially in the lower limbs (95% vs. 5%). A revascularization procedure was performed in 14 patients (63.6%) of the patients, and primary amputation was unavoidable in five patients (22.7%). Three patients (13.6%) did not undergo operative management, two because of their hemodynamic instability and one rejected surgery. We performed 23 revascularization procedures for 14 patients and three primary amputations. Thromboembolectomy (TE) was the technique of choice (92.8%). Below-the-knee (BTK) femoropopliteal bypass was performed in one patient. Selective tibial vessel thrombectomy was performed in four patients (28.6%). The mortality rate was 27.3%. Among survivors, two secondary amputations were needed with a limb salvage rate of 68.2%. Conclusion By the apparent end of the pandemic, our study further supports the increased risk of ALI in COVID-19-positive patients. Moreover, the results affirm the unfavorable outcomes highly impacted by rethrombosis, reinterventions, and consequently high rates of amputations and mortality.

Abstract
Massive pulmonary embolism (MPE) is a high-risk medical emergency. Seizure as the clinical presentation of MPE is extremely rare, and to our knowledge, there have been no reports on successful percutaneous, catheter-based treatment of MPE presenting with new-onset seizures and cardiac arrest. In this report, we discuss the case of a 64-year-old woman who presented with an episode of seizure that lasted 5 h. Seizure occurred four times within 12 h after arrival at the hospital, and in the end, she sustained a cardiac arrest. The patient had no past history of seizure or cardiopulmonary disease. Bilateral MPE was detected by a computed tomography pulmonary angiogram, and she was successfully treated with percutaneous, catheter-directed anticoagulant therapy. Pulmonary embolism-related seizures are more difficult to diagnose and have higher mortality rates than seizures. MPE should be suspected in patients presenting with new-onset seizures and hemodynamic instability.

Abstract
Pulmonary embolectomy has a chequered history but the quest to surgically treat a patient diagnosed with pulmonary embolism effectively spurred the development of cardiopulmonary bypass and a new dawn for cardiac surgery. The advent of cardiopulmonary bypass, extracorporeal membrane oxygenation, and computed tomography pulmonary angiogram has allowed rapid diagnosis and made surgical pulmonary embolectomy a relatively safe procedure that should be considered when indicated. Pulmonary emboli in donor lungs, often get rejected for transplantation. Ex vivo lung perfusion is among newly available technology with the ability to not only recondition marginal lungs but also treat donor lung pulmonary embolisms, effectively increasing the donor pool.

Abstract
Purpose: This study aimed to investigate the visual outcomes and anatomical changes after vitrectomy for retinal artery occlusion. Methods: Twelve patients with retinal artery occlusion (11 central retinal artery occlusion and 1 branch retinal artery occlusion) were part of this study. Our patients were treated with vitrectomy with arteriotomy or with neurotomy and arteriotomy. Complete ophthalmic examination was performed preoperatively, at 2 weeks, and 1, 3, 6, 9, and 12 months after surgery. Results: The mean preoperative best-corrected visual acuity (BCVA) was 1.94 logMAR, and the final BCVA after 12-months follow-up was 2.04 logMAR. After vitrectomy with arteriotomy, the BCVA in patients treated with neurotomy and arteriotomy was 1.65 and 2.45, respectively (P = 0.038). Conclusion: No benefits have been achieved from using vitrectomy in retinal artery occlusion cases.

Abstract
Severe forms of pulmonary embolism (PE) in children, althought rare, cause significant morbidity and mortality. We review the pathophysiologic features of severe (high-risk and intermediate-risk) PE and suggest novel pediatric-specific risk stratifications and an acute treatment algorithm to expedite emergent decision-making. We defined pediatric high-risk PE as causing cardiopulmonary arrest, sustained hypotension, or normotension with signs or symptoms of shock. Rapid primary reperfusion should be pursued with either surgical embolectomy or systemic thrombolysis in conjunction with a heparin infusion and supportive care as appropriate. We defined pediatric intermediate-risk PE as a lack of systemic hypotension or compensated shock, but with evidence of right ventricular strain by imaging, myocardial necrosis by elevated cardiac troponin levels, or both. The decision to pursue primary reperfusion in this group is complex and should be reserved for patients with more severe disease; anticoagulation alone also may be appropriate in these patients. If primary reperfusion is pursued, catheter-based therapies may be beneficial. Acute management of severe PE in children may include systemic thrombolysis, surgical embolectomy, catheter-based therapies, or anticoagulation alone and may depend on patient and institutional factors. Pediatric emergency and intensive care physicians should be familiar with the risks and benefits of each therapy to expedite care. PE response teams also may have added benefit in streamlining care during these critical events.

Abstract
Introduction Microsurgical embolectomy though is the oldest known recanalization technique is being dismissed in favor of the latest mechanical endovascular techniques for the management of acute large vessel occlusion. Aim and Objective We aim to highlight the role of microsurgical embolectomy in the current era of pharmacological and mechanical (endovascular) thrombolysis. Methods An outline of the microsurgical embolectomy technique is described along with its current indications, advantages, and disadvantages. Results It carries higher complete (TICI 3) revascularization rates with lower risk of distal embolic events especially in cases with high clot burdens; but is more labor-intensive and has longer reperfusion time in comparison to endovascular methods along with the requirement of highly skilled neurovascular surgeons to perform it quickly. Conclusion Microsurgical embolectomy is an important indispensable recanalization technique in the armamentarium of vascular neurosurgeons.

Abstract
Intermediate-risk (submassive) pulmonary embolism (PE) describes normotensive patients with evidence of right ventricular compromise, whereas high-risk (massive) PE comprises those who have experienced hemodynamic decompensation with hypotension, cardiogenic shock, or cardiac arrest. Together, these 2 syndromes represent the most clinically challenging manifestations of the PE spectrum. Prompt therapeutic anticoagulation remains the cornerstone of therapy for both intermediate- and high-risk PE. Patients with intermediate-risk PE who subsequently deteriorate despite anticoagulation and those with high-risk PE require additional advanced therapies, typically focused on pulmonary artery reperfusion. Strategies for reperfusion therapy include systemic fibrinolysis, surgical pulmonary embolectomy, and a growing number of options for catheter-based therapy. Multidisciplinary PE response teams can aid in selection of appropriate management strategies, especially where gaps in evidence exist and guideline recommendations are sparse.

Abstract
Objectives Acute pulmonary embolism can be a life-threatening condition with a high mortality. The treatment choice is a matter of debate. The early and late outcomes of patients treated with surgical pulmonary embolectomy for acute pulmonary embolism in a single center were analyzed. Methods All consecutive patients operated on for pulmonary embolism between January 2002 and March 2017 were reviewed. Patient demographics and pre- and postoperative clinical data were retrieved from our patient registry, and risk factors for in-hospital and long-term mortality were identified. Results In total, 175 patients (mean age 59±3 years, 50% male) were operated on for acute pulmonary embolism. In-hospital mortality was 19% (34/175). No differences were found when comparing surgery utilizing a beating heart or cardioplegic arrest. Risk factors for in-hospital mortality were age >70 years [odds ratio (OR) 4.8, confidence interval (CI) 1.7–13.1, p=0.002], body surface area <2 m2 (OR 4.7, CI 1.6–13.7, p=0.004), preoperative resuscitation (OR 14.1, CI 4.9–40.8, p<0.001), and the absence of deep vein thrombosis (OR 9.6, CI 2.5–37.6, p<0.001). Follow-up was 100% complete with a 10-year survival rate of 66.4% in 141/175 patients surviving to discharge. Once discharged from hospital, none of the risk factors identified for in-hospital mortality were relevant for long-term survival except the absence of deep vein thrombosis (OR 3.2, CI 1.2–8.2, p=0.019). The presence of malignancy was a relevant risk factor for long-term mortality (OR 4.3, CI 1.8–10.3, p=0.001). Conclusion Surgical pulmonary embolectomy as a therapy for acute pulmonary embolism demonstrates excellent short- and long-term results in patients with an otherwise life-threatening disease, especially in younger patients with a body surface area >2 m2 and pulmonary embolism caused by deep vein thrombosis. Pulmonary embolectomy should therefore not be reserved as a treatment of last resort for clinically desperate circumstances.

Abstract
A 58-year-old man who presented with syncope, dyspnea, and hemodynamic compromise was found to have large free-floating right atrial thrombuses on echocardiogram. Decision was made to transfer the patient for emergent atriotomy. Cardiothoracic surgeons declared the patient as inoperable and recommended to use a lytic agent. Alteplase was administered with subsequent near-complete resolution of symptoms and near-normalization of echocardio-graphic parameters. The post-thrombolytic course was complicated by saddle pulmonary emboli requiring embolectomy. Catheter embolectomy was not available and cardiothoracic surgeon in other center considered the patient to be very high risk for transferring between hospitals and surgical intervention. Ultimately, the critical decision was made, despite the patient having been administered thrombolytic therapy within the previous 48 hours. Alteplase was given, but was not effective and the patient required surgical intervention. Surgical embolectomy was done successfully in another hospital and the patient was discharged with warfarin.

Abstract
RATIONALE Right heart thrombi (RiHT) is characterized by the presence of thrombus within the right atrium or right ventricle (RV). Current literature suggests pulmonary embolism (PE) with RiHT carries a high mortality. Guidelines lack recommendations in managing RiHT. We created a pooled analysis on RiHT and report on our institutional experience in managing RiHT. We aimed to evaluate whether patient characteristics and differing treatment modalities predict mortality. METHODS We created a pooled analysis of case reports and series of patients with RiHT and PE between January 1956 and 2017. We also reviewed a series of consecutive patients with RiHT identified from our institutional PE registry. Age, shock, RV dysfunction, clot mobility, treatment modality, and hospital outcome had to be reported. RESULTS We identified 316 patients in our pooled analysis. Patients received the following therapies: no treatment 15 (5%), systemic anticoagulation 73 (23%), systemic thrombolysis 108 (34%), surgical embolectomy 101 (32%), catheter-directed therapy 11 (3%), and systemic thrombolysis with surgery 8 (3%). In-hospital mortality was 18.7%. Univariate analysis showed age and shock reduced odds of survival. Multivariate analysis showed shock reduced odds of survival (odds ratios [OR] 0.36, 95% confidence interval [CI]: 0.19-0.72, P ≤ .01) while age, RV dysfunction, and clot-mobility did not affect mortality. In a reduced multivariate analysis adjusting for shock, treatment modality, and clot location alone, systemic thrombolysis increased odds of survival when compared to systemic anticoagulation (OR 2.72, 95% CI: 1.11-6.64, P = .02). Our institutional series identified 18 patients, where in-hospital mortality was 22.2%, 18 (100%) had RV dysfunction, and 5 (28%) had shock. Patients received the following therapies: systemic anticoagulation 8 (44.4%), systemic thrombolysis 4 (22.2%), surgical embolectomy 4 (22.2%), and catheter-directed thrombolysis 2 (11.1%). CONCLUSION Presence of shock in RiHT is an independent predictor of mortality. Systemic thrombolysis may offer increased odds of survival when compared to systemic anticoagulation. Our findings should be interpreted with caution as they derive from retrospective reports and subject to publication bias.

Abstract
Ischemic stroke due to an acute occlusion of the extracranial internal carotid artery (eICA) is associated with high morbidity and mortality. The best treatment option remains unclear. This study aims to increase the available therapeutic experience documented for surgical recanalization of acute eICA occlusions. We retrospectively reviewed all hospital records of the University Hospital Jena between 2006 and 2018 to identified patients with acute ischemic stroke due to an occlusion of the eICA who underwent emergent surgical recanalization. We analyzed clinical data, surgical reports, imaging data, and outpatient records. The primary outcome parameter was the modified Rankin Scale (mRS) at 3 months. During the survey, 12 patients (mean age: 62.3 ± 10.8 years; range: 35-87) underwent emergent surgical recanalization for an acutely symptomatic eICA occlusion. All patients presented with neurological deficits with a mean National Institutes of Health Stroke Scale score at admission of 15.0 ± 5.1 (range 2-23). Patients were selected for surgery mainly due to the extent of the perfusion mismatch, while stroke severity and age were also considered. The median time from symptom onset to surgery was 309 ± 122 minutes (range 112-650 minutes). Complete recanalization was obtained in all 12 patients. No patient deteriorated postoperatively, no intracranial hemorrhage was observed, and no patient died in the following 3 months. Favorable outcomes (mRS: 0-2) after 3 months were achieved in 7 of 12 patients. The current study adds support to previous findings that the surgical recanalization of acute eICA occlusions is a possible and safe treatment option. However, a critical patient selection based on mismatch size in perfusion imaging is crucially important for successful treatment.

Abstract
Massive pulmonary embolism (PE) is a severe condition that can potentially lead to death caused by right ventricular (RV) failure and the consequent cardiogenic shock. Despite the fact thrombolysis is often administrated to critical patients to increase pulmonary perfusion and to reduce RV afterload, surgical treatment represents another valid option in case of failure or contraindications to thrombolytic therapy. Correct risk stratification and multidisciplinary proactive teams are critical factors to dramatically decrease the mortality of this global health burden. In fact, the worldwide incidence of PE is 60-70 per 100,000, with a mortality ranging from 1% for small PE to 65% for massive PE. This review provides an overview of the diagnosis and management of this highly lethal pathology, with a focus on the surgical approaches at the state of the art.

Abstract
Massive pulmonary embolus (PE), defined as hemodynamic shock from acute PE, is a life-threatening condition. Deaths from massive PE, especially when unsuspected, occur within minutes to hours of onset and as such prompt intervention can be lifesaving. Acute massive PE patients have traditionally been candidates for treatment with intravenous systemic thrombolysis to improve pulmonary artery pressure, arteriovenous oxygenation, and pulmonary perfusion in an effort to reduce mortality. However, patients with contraindications to systemic thrombolysis or those who have failed thrombolysis may benefit from other techniques including endovascular and surgical embolectomy. This article will review the current medical management as well as catheter-directed therapies and surgical embolectomy in the treatment of patients with massive PE.

Abstract
Background Floating right heart thrombi (RHT) are in transit from the legs to the pulmonary arteries and thus are a severe form of venous thromboembolism (VTE), with a high early mortality rate without treatment. There is a lack of evidence-based recommendations for its management. The objective of this study is to describe our experience in the surgical management of thrombus-in-transit and pulmonary embolism (PE) in a tertiary hospital. Methods We recruited four patients with thrombus-in-transit and PE treated with early surgical embolectomy and anticoagulation. Epidemiologic, laboratory, imaging and clinical data of the thromboembolic episode and the subsequent course were collected. Results The sample included 3 males and 1 female, with a mean age of 49.7. The most frequent initial symptoms were dyspnea, syncope, chest pain and signs of deep vein thrombosis (DVT). Transthoracic echocardiogram (TTE) found the thrombus-in-transit in all the cases. The inicial treatment was unfractionated heparin (UFH) and urgent right atriectomy and manual removal of the thrombi. Three patients needed perioperative infusion of vasopressor drugs. All patients had right heart dysfunction at the time of diagnosis. The mean scoring in the Pulmonary Embolism Severity Index (PESI) was 90. All patients survived after 30 days of follow-up. Conclusions Early surgical embolectomy of thrombus-in-transit is an effective option of management in selected patients, although the current evidence to support this approach is not definitive.

Outcome of surgical embolectomy in patients with massive pulmonary embolism with and without cardiopulmonary resuscitation. POLISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2017; 14:241-244. [PMID: 29354176 PMCID: PMC5767774 DOI: 10.5114/kitp.2017.72228] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Accepted: 11/12/2017] [Indexed: 11/17/2022]
Abstract
Introduction Pulmonary embolism is a challenging critical cardiovascular disease with high morbidity and mortality. Surgical embolectomy has favorable results in patients with massive pulmonary embolism. Aim To study the outcome of embolectomy in patients with massive pulmonary embolism. Material and methods In this single-center, retrospective study, 36 patients including 14 male and 22 female patients with a mean age of 50.80 ±18.89 years with acute pulmonary embolism who underwent surgical pulmonary embolectomy from January 2011 to January 2016 were included. The medical records of all patients were reviewed for demographic and preoperative data and postoperative outcomes. Results Common risk factors for acute PE were major surgery within 3 months and deep vein thrombosis. The most common presenting symptoms of patients were dyspnea, followed by chest pain and syncope. Mean duration of hospitalization was 14.76 ±8.69 days and mean operation duration was 4.47 ±1.54 h. Mean time from admission to embolectomy was 6.58 ±1.13 h. Ten (27.8%) patients died during the operation including 3 cases with cardiopulmonary resuscitation prior to surgery and 2 cases with severe cardiogenic shock. Patients who survived were followed for 6 months. The mortality rate during follow-up was 15.4%; all 4 patients died during follow-up period due to metastatic cancer. No pulmonary embolism recurrance were seen. Conclusions Although surgical embolectomy mostly was done for high risk patients, it had good in-hospital and excellent mid-term outcomes.

Abstract
Acute massive pulmonary embolism is a life-threatening emergency that must be promptly diagnosed and managed. Over the last several years, the use of computed tomography scanning has improved the clinician's ability to diagnose acute pulmonary embolism. We report two cases of acute massive pulmonary embolism who presented with sudden onset of dyspnea and underwent successful open pulmonary embolectomy. The first case presented with acute onset of dyspnea of 2 days duration, in view of hemodynamic deterioration and two-dimensional echocardiography, it revealed clot in right ventricular (RV) apex and right pulmonary artery; the patient underwent cardiopulmonary bypass and open pulmonary embolectomy with RV clot extraction. The second case presented with a sudden onset of dyspnea on the 15(th) postoperative day for traumatic rupture of urinary bladder, in view of recent surgery, the patient was subjected to surgical embolectomy. Following surgical intervention, both the patients made a prompt recovery.

Trends in the Management and Outcomes of Acute Pulmonary Embolism: Analysis From the RIETE Registry. J Am Coll Cardiol 2016; 67:162-170. [PMID: 26791063 DOI: 10.1016/j.jacc.2015.10.060] [Citation(s) in RCA: 219] [Impact Index Per Article: 27.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2015] [Revised: 10/07/2015] [Accepted: 10/13/2015] [Indexed: 12/16/2022]
Abstract
BACKGROUND Despite advances in hospital management in recent years, it is not clear whether mortality after acute pulmonary embolism (PE) has decreased over time. OBJECTIVES This study describes the trends in the management and outcomes of acute symptomatic PE. METHODS We identified adults with acute PE enrolled in the registry between 2001 and 2013. We assessed temporal trends in length of hospital stay and use of pharmacological and interventional therapies. Using multivariable regression, we examined temporal trends in risk-adjusted rates of all-cause and PE-related death to 30 days after diagnosis. RESULTS Among 23,858 patients with PE, mean length of stay decreased from 13.6 to 9.3 days over time (32% relative reduction, p < 0.001). For initial treatment, use of low-molecular-weight heparin increased from 77% to 84%, whereas the use of unfractionated heparin decreased from 22% to 8.4% (p < 0.001 for trend for all comparisons). Thrombolytic therapy use increased from 0.7% to 1.0% (p = 0.07 for trend) and surgical embolectomy use doubled from 0.3% to 0.6% (p < 0.01 for trend). Risk-adjusted rates of all-cause mortality decreased from 6.6% in the first period (2001 to 2005) to 4.9% in the last period (2010 to 2013) (p = 0.02 for trend). Rates of PE-related mortality decreased over time, with a risk-adjusted rate of 3.3% in 2001 to 2005 and 1.8% in 2010 to 2013 (p < 0.01 for trend). CONCLUSIONS In a large international registry of patients with PE, improvements in length of stay and changes in the initial treatment were accompanied by a reduction in short-term all-cause and PE-specific mortality.

Abstract
The objective was to compare the efficacy of treatment options for right heart thrombi (RHT) in transit. All published reports between 1992 and 2013 were identified and pooled. We analyzed 328 patients with RHT and pulmonary embolism (PE). The treatments administered were none in 11 patients (3.4%), anticoagulation (AC) with heparin in 70 patients (21.3%), thrombolytics in 122 patients (37.2%), catheter-related treatments in five patients (1.5%) and surgical embolectomy in 120 patients (36.6%). The overall short-term mortality for the entire cohort was 23.2%. The mortality rate associated with no therapy was highest at 90.9%. The mortality associated with AC alone was significantly higher than surgical embolectomy or thrombolysis (37.1% vs 18.3% vs 13.7%, respectively). In univariate analysis, any therapy was better than no therapy with a favorable odds of 16.92 (95% CI 2.05-139.87) for AC, 61.76 (95% CI 7.42-513.81) for thrombolysis and 44.54 (95% CI 5.42-366.32) for surgical embolectomy. In multivariate analysis with age and hemodynamic status entered as covariates, thrombolytic therapy was better than AC with favorable odds of 4.83 (95% CI 1.52-15.36). Similarly, there was a trend in favor of surgical embolectomy with an odds of 2.61 (95% CI 0.90-7.58). The estimated probability of survival in hemodynamically unstable patients with AC, surgical embolectomy and thrombolysis was 47.7%, 70.45% and 81.5%, respectively. There was no significantly increased risk of complications with thrombolytic therapy. In conclusion, left untreated, patients with RHT and PE have very high mortality. Aggressive management with thrombolysis or surgical thrombectomy may be more effective than AC alone in the management of these patients.

Emergent surgical embolectomy in conjunction with cervical internal carotid ligation and superficial temporal artery-middle cerebral artery bypass to treat acute tandem internal carotid and middle cerebral artery occlusion due to cervical internal carotid artery dissection. Surg Neurol Int 2016; 6:191. [PMID: 26759736 PMCID: PMC4697205 DOI: 10.4103/2152-7806.172536] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2015] [Accepted: 10/30/2015] [Indexed: 11/29/2022] Open
Abstract
Background: Acute tandem cervical dissecting internal carotid artery (ICA) occlusion and intracranial embolic middle cerebral artery (MCA) occlusion can be devastating, and the optimal treatment strategy for this condition has not been established yet. Case Description: A 45-year-old male presented with aphasia and right hemiparesis preceded by neck pain. Computed tomography showed a high-density signal along the left MCA, suggesting extensive emboli. Magnetic resonance angiography demonstrated tandem occlusion of the left cervical ICA and intracranial MCA with minimal diffusion-weighted imaging lesion. Emergent surgical embolectomy was performed, and long intracranial MCA emboli were retrieved with collateral cross-flow restoration. The cervical ICA was exposed, and dissection was confirmed. The cervical ICA was ligated, and superficial temporal artery (STA)-MCA anastomosis was added. Postoperatively, the patient demonstrated recovery from right hemiparesis and aphasia. At the 6th postoperative month, follow-up studies demonstrated a robustly patent STA-MCA bypass and no additional ischemic lesion on T2-weighted imaging. Conclusions: Surgical embolectomy in conjunction with ligation of the cervical ICA followed by STA-MCA bypass might be a safe alternative method to endovascular recanalization, when the cervical dissection is extensive and when huge secondary emboli are present along the MCA.

Abstract
Background: Central retinal artery occlusion (CRAO) is a stroke of the retina and is associated with extremely poor prognosis. Although the pathophysiology of CRAO is diverse, including autoimmune or hematological disorders, neurosurgeons can perform carotid endarterectomy for the causal internal carotid artery stenosis or perform acute recanalization of the extra- or intracranial artery occlusion due to cardiogenic embolism. Case Description: A 78-year-old male with a history of atrial fibrillation (Af) visited our hospital with a chief complaint of right monocular blindness. Magnetic resonance imaging revealed occlusion of the right internal and external carotid arteries. We performed emergent cervical surgical embolectomy for restoration of vision. Recanalization was accomplished within 8 h after onset, and the patient regained practical vision within 4 months. Conclusion: In the diagnosis and treatment of CRAO, occlusion of the internal and/or external carotid artery due to large cardiac emboli should be taken in consideration, especially when the patient has a history of Af, since acute recanalization might restore vision.

Abstract
OBJECTIVE Acute massive pulmonary embolism (PE) is associated with significant mortality rate despite diagnostic and therapeutic advances. The aim of this study was to analyze our clinical outcomes of patients with acute massive PE who underwent emergency surgical pulmonary embolectomy. METHODS This retrospective study included 13 consecutive patients undergoing emergency surgical pulmonary embolectomy for acute massive PE at our institution from March 2000 to November 2013. The medical records of all patients were reviewed for demograhic and preoperative data and postoperative outcomes. All patients presented with cardiogenic shock with severe right ventricular dysfunction confirmed by echocardiography, where 4 (30.8%) of the patients experienced cardiac arrest requiring cardiopulmonary resuscitation before surgery. RESULTS The mean age of patients was 61.8 ± 14 years (range, 38 to 82 years) with 8 (61.5%) males. The most common risk factors for PE was the history of prior deep venous thrombosis (n = 9, 69.2%). There were 3 (23.1%) in-hospital deaths including operative mortality of 7.7% (n = 1). Ten (76.9%) patients survived and were discharged from the hospital. The mean follow-up was 25 months; follow-up was 100% complete in surviving patients. There was one case (7.7%) of late death 12 months after surgery due to renal carcinoma. Postoperative echocardiographic pressure measurements demonstrated a significant reduction (P < 0.001). At final follow-up, all patients were in New York Heart Association class I and no readmission for a recurrent of PE was observed. CONCLUSION Surgical pulmonary embolectomy is a reasonable option and could be performed with acceptable results, if it is performed early in patients with acute massive PE who have not reached the profound cardiogenic shock or cardiac arrest.

Abstract
Background: Occlusion of the intracranial main trunk results in a poor functional outcome and a high mortality rate. Accordingly, some revascularization procedures such as intravenous administration of recombinant tissue plasminogen activator (rt-PA), endovascular surgery, or surgical embolectomy in the very acute stage have been attempted. Case Description: We describe two patients with middle cerebral artery occlusion due to cardiogenic embolism. One patient was subjected to surgical embolectomy shortly after intravenous rt-PA and the other was subjected to same after intra-arterial urokinase. Complete recanalization without new cerebral infarction territory was achieved in both patients. Conclusion: Based on our experience, we think that surgical embolectomy is an effective and safe procedure and should be attempted when no response to early thrombolytic therapy is obtained.

Abstract
BACKGROUND Acute pulmonary embolism (APE) has high mortality. Some APEs with circulatory collapse or cardiopulmonary arrest have been treated by percutaneous cardiopulmonary support (PCPS) in Japan. But there have been no reports with a large number of series of APE treated with the use of PCPS. METHODS AND RESULTS We collected all the reported cases with acute thrombotic pulmonary embolism treated with PCPS before surgical embolectomy or those without surgical embolectomy in Japan, and assessed the effectiveness of PCPS. PCPS was combined with surgical embolectomy in 35% (68 of 193), thrombolytic therapy in 62% (120/193), and catheter therapy in 24% (46/193). The survival rate treated with PCPS was 73% (80% in surgical embolectomy, 71% in thrombolytic therapy, and 76% in catheter therapy). Logistic regression analysis showed that the mortality rate was elevated in cases with cardiopulmonary arrest (odds ratio [OR], 3.41; 95% confidence interval [CI], 1.52-7.67; p-value, 0.003) but not by surgical embolectomy (OR, 0.99; 95% CI, 0.39-2.53; p-value, 0.98), catheter therapy (OR, 0.71; 95% CI, 0.30-1.72; p-value, 0.45), and thrombolysis (OR, 1.60; 95% CI, 0.64-3.99; p-value, 0.31) as regards to the concomitant therapies with PCPS. CONCLUSION PCPS might improve the survival rate in APE patients with circulatory collapse or cardiopulmonary arrest, but there was no differences in outcome among cases treated by surgical embolectomy, catheter therapy, and thrombolysis as the concomitant therapies.
