[Propofol Infusion Syndrome Treated Successfully by Early Diagnosis].

Propofol infusion syndrome (PRIS) is one of the severe complications which occur during continuous venous infusion of propofol, and has a high mortality rate. It is featured by high fever, oliguria, myogloblin urine, acute renal failure, hepatomegaly, fatty liver, and so on. We have experienced a case of PRIS who was saved by prompt changing of sedatives from propofol to midazolam and dexmedetomidine. The patient was an 82-year-old man, who underwent off-pump coronary bypass grafting due to effort angina pectoris. After the operation, he suffered from continuous high fever over 38 ℃, acute renal impairment, and high level of creatine kinase (CK) without CK-MB increment, suggesting PRIS. We promptly changed sedatives from propofol to midazolam and dexmedetomidine, then the patient recuperated from these abnormalities. It is strongly suggested that meticulous observation is necessary during propofol infusion.

[Risk Factors for Early Progression of Carotid Stenosis after Cervical Radiation Therapy].

OBJECTIVE: Carotid stenosis may occur as a late complication following cervical radiation therapy(RT);however, it may also progress in the early post-RT period. This study aimed to characterize the clinical features associated with the early progression of post-RT carotid stenosis. METHODS: We retrospectively reviewed clinical records of 30 patients who had undergone unilateral or bilateral cervical RT between January 2010 and November 2014. We analyzed the pre- and post-RT stenosis of their carotid arteries using contrast-enhanced computed tomography images. The arteries were classified as progressive or non-progressive according to the presence or absence of stenosis progression within five years after RT. Using univariate and multivariate analyses, we evaluated the following potential clinical risk factors:age;gender;history of hypertension, hyperlipidemia, diabetes mellitus, coronary artery disease, or smoking habit;antiplatelet or statin use;radiation dose;and prior presence of carotid stenosis before RT. RESULTS: In total, we reviewed 57 irradiated carotid arteries and identified 9 with early post-RT progression. Carotid stenosis before RT was observed in 88.9% of arteries in the progressive group but only 2% of arteries in the non-progressive group and it predicted progression(univariate and multiple logistic regression analyses, p<0.0001). No other clinical characteristics had a significant association with the progression of carotid stenosis. CONCLUSION: Prior presence of carotid stenosis may be a risk factor for its early progression after RT. Pre-RT screening of cervical arteries may be useful, and strict management of carotid stenosis is critical in patients with cervical radiation therapy.

[Therapeutic Effects of Low-Dose Bevacizumab for the Treatment of Recurrent Brain Metastases].

OBJECTIVE: Molecularly targeted therapy has been adopted to treat a number of cancers. Bevacizumab, a recombinant humanized monoclonal antibody against vascular endothelial growth factor, is a representative agent used in molecularly targeted therapeutic regimens. However, the therapeutic effect of bevacizumab for the treatment of brain metastases remains unknown. We report the clinical effects of low dose bevacizumab(≤2.5mg/kg/week)to treat recurrent brain metastases. METHODS: We retrospectively analyzed patients with brain metastases who had been treated with bevacizumab between 2012 and 2016 at our institution. We identified clinical characteristics, including age, gender, primary tumor site, dose of bevacizumab, therapeutic and adverse effects, and magnetic resonance imaging results. The lesions were assessed with the RECIST criteria based on gadolinium-enhanced T1-weighted, T2-weighted, and FLAIR images. Statistical analysis was performed using t-test and Fisher's exact test. RESULTS: The cohort comprised 26 patients(8 men, 18 women)with a median age of 61 years(range 39-82 years). There were no significant clinical differences between the low dose and non-low dose groups. Patients in the low dose group did not report any adverse effects from bevacizumab. Three patients with brain metastases from colon cancer are illustrated to report the clinical course of low dose bevacizumab. CONCLUSION: Low dose bevacizumab may be a safe and effective therapeutic option to treat recurrent brain metastases from bevacizumab-sensitive cancers.

Immunoglobulin G4-related multiple cardiovascular lesions successfully treated with a combination of open surgery and corticosteroid therapy.

Immunoglobulin G4-related disease, a newly emerging systemic autoimmune disorder, can potentially involve the cardiovascular system. The standard treatment for immunoglobulin G4-related cardiovascular disease has not been established. We encountered a very rare case of an immunoglobulin G4-related inflammatory abdominal aortic aneurysm coexisting with a coronary artery aneurysm and periarteritis. The patient underwent surgical resection for the abdominal aortic aneurysm, followed by successful corticosteroid therapy for the coronary artery lesions. This is the first report of steroid-sensitive immunoglobulin G4-related coronary artery disease. A carefully planned treatment strategy for the multiple cardiovascular lesions was invaluable in the present case.

Asymmetric synthesis of the carbon-14-labeled selective glucocorticoid receptor modulator using cinchona alkaloid catalyzed addition of 6-bromoindole to ethyl trifluoropyruvate.

We describe in this study the asymmetric synthesis of radioisotope (RI)-labeled selective glucocorticoid receptor modulator. This synthesis is based on optimization of the cinchona alkaloid catalyzed addition of 6-bromoindole to ethyl trifluoropyruvate and Negishi coupling of zinc cyanide to the 6-bromoindole moiety. [¹4C] Labeled (-)-{4-[(1-{2-[6-cyano-1-(cyclohexylmethyl)-1H-indol-3-yl]-3,3,3-trifluoro-2-hydroxypropyl}piperidin-4-yl)oxy]-3-methoxyphenyl}acetic acid (-)-1 was synthesized successfully with high enantioselectivity (>99% ee) and sufficient radiochemical purity.

Incidence and Risk Factors of Symptomatic Radiation Pneumonitis in Non-Small-Cell Lung Cancer Patients Treated with Concurrent Chemoradiotherapy and Consolidation Durvalumab.

INTRODUCTION: Data on the risk factors for symptomatic radiation pneumonitis (RP) in non-small-cell lung cancer (NSCLC) patients treated with concurrent chemoradiotherapy (CCRT) and consolidation durvalumab are limited; we aimed to investigate these risk factors. MATERIALS AND METHODS: This multicenter retrospective study, conducted at 15 institutions in Japan, included patients who were ≥20 years of age; who started definitive CCRT for NSCLC between July 1, 2018, and July 31, 2019; and who then received durvalumab. The primary endpoint was grade 2 or worse (grade 2+) RP. RESULTS: In the 146 patients analyzed, the median follow-up period was 16 months. A majority of the patients had stage III disease (86%), received radiation doses of 60 to 66 Gy equivalent in 2-Gy fractions (93%) and carboplatin and paclitaxel/nab-paclitaxel (77%), and underwent elective nodal irradiation (71%) and 3-dimensional conformal radiotherapy (75%). RP grade 2 was observed in 44 patients (30%); grade 3, in four patients (3%); grade 4, in one patient (1%); and grade 5, in one patient (1%). In the multivariable analysis, lung V20 was a significant risk factor, whereas age, sex, smoking history, irradiation technique, and chemotherapy regimen were not. The 12-month grade 2+ RP incidence was 34.4% (95% confidence interval [CI], 26.7%-42.1%); the values were 50.0% (95% CI, 34.7%-63.5%) and 27.1% (95% CI, 18.8%-36.2%) in those with lung V20 ≥ 26% and < 26%, respectively (P = .007). CONCLUSION: The incidence of grade 2+ RP was relatively high in this multicenter real-world study, and its risk increased remarkably at elevated lung V20. Our findings can aid in RP risk prediction and the safe radiotherapy treatment planning.

Long-term outcomes of three-dimensional conformal radiation therapy combined with neoadjuvant hormonal therapy in Japanese patients with locally advanced prostate cancer.

BACKGROUND: The outcomes of three-dimensional conformal radiation therapy (3D-CRT) combined with neoadjuvant hormonal therapy (NAHT) in Japanese patients with locally advanced prostate cancer who initiated salvage hormonal therapy (SHT) at a relatively early phase were evaluated. METHODS: Between April 1998 and April 2003, 70 Japanese patients with T3N0M0 prostate cancer who received radical 3D-CRT treatment were evaluated. The median age, initial prostate-specific antigen (PSA) level, and duration of NAHT were 73 years old, 26.3 ng/ml, and 4 months, respectively. Seventy grays were given in 35 fractions that were confined to the prostate and seminal vesicles. Adjuvant hormonal therapy was not administered after 3D-CRT in any of the cases. RESULTS: The median follow-up period was 64.9 months. The median PSA value at the time of initiation of SHT was 5.0 ng/ml (range 0.1-21.6 ng/ml). Overall, disease-specific, PSA failure-free (based on the Phoenix definition) and SHT-free survival rates at 5 years were 90.3% (95% CI 86.5-94.0), 96.5% (94.0-98.9), 60.5% (48.2-72.7), and 63.5% (57.2-69.8), respectively. Therefore, two-thirds of the patients were still hormone-free at 5 years. CONCLUSIONS: PSA control rates in our series of Japanese patients with stage T3N0M0 prostate cancer treated with the standard dose of 3D-CRT combined with NAHT seemed higher than expected. This approach involving 3D-CRT combined with NAHT with the initiation of SHT at PSA values of around 5 ng/ml may be one option for Japanese patients with locally advanced prostate cancer, although further prospective study is required to confirm the validity.

A case of giant right coronary artery aneurysm due to IgG4-related disease.

A man diagnosed with immunoglobulin G4 (IgG4)-related disease at the age of 65 years underwent abdominal aortic replacement due to an abdominal aortic aneurysm. In the same hospitalization period, a small coronary artery aneurysm was noticed. He was treated with corticosteroids and his serum IgG levels returned to normal. After experiencing sudden chest pain at age 74 years, coronary angiography showed that the size of the aneurysm had increased dramatically. He underwent coronary artery bypass graft and coronary artery resection without using cardiopulmonary bypass. Thus, we conclude that observation of aneurysms in patients with IgG4-related disease is important, even under corticosteroid therapy.

Application and limitation of radiomics approach to prognostic prediction for lung stereotactic body radiotherapy using breath-hold CT images with random survival forest: A multi-institutional study.

PURPOSE: To predict local recurrence (LR) and distant metastasis (DM) in early stage non-small cell lung cancer (NSCLC) patients after stereotactic body radiotherapy (SBRT) in multiple institutions using breath-hold computed tomography (CT)-based radiomic features with random survival forest. METHODS: A total of 573 primary early stage NSCLC patients who underwent SBRT between January 2006 and March 2016 and met the eligibility criteria were included in this study. Patients were divided into two datasets: training (464 patients in 10 institutions) and test (109 patients in one institution) datasets. A total of 944 radiomic features were extracted from manually segmented gross tumor volumes (GTVs). Feature selection was performed by analyzing inter-segmentation reproducibility, GTV correlation, and inter-feature redundancy. Nine clinical factors, including histology and GTV size, were also used. Three prognostic models (clinical, radiomic, and combined) for LR and DM were constructed using random survival forest (RSF) to deal with total death as a competing risk in the training dataset. Robust models with optimal hyper-parameters were determined using fivefold cross-validation. The patients were dichotomized into two groups based on the median value of the patient-specific risk scores (high- and low-risk score groups). Gray's test was used to evaluate the statistical significance between the two risk score groups. The prognostic power was evaluated by the concordance index with the 95% confidence intervals (CI) via bootstrapping (2000 iterations). RESULTS: The concordance indices at 3 yr of clinical, radiomic, and combined models for LR were 0.57 [CI: 0.39-0.75], 0.55 [CI: 0.38-0.73], and 0.61 [CI: 0.43-0.78], respectively, whereas those for DM were 0.59 [CI: 0.54-0.79], 0.67 [CI: 0.54-0.79], and 0.68 [CI: 0.55-0.81], respectively, in the test dataset. The combined DM model significantly discriminated its cumulative incidence between high- and low-risk score groups (P < 0.05). The variable importance of RSF in the combined model for DM indicated that two radiomic features were more important than other clinical factors. The feature maps generated on the basis of the most important radiomic feature had visual difference between high- and low-risk score groups. CONCLUSIONS: The radiomics approach with RSF for competing risks using breath-hold CT-based radiomic features might predict DM in early stage NSCLC patients who underwent SBRT although that may not have potential to predict LR.

Stereotactic body radiotherapy for oligometastatic lung tumors.

PURPOSE: Since 1998, we have treated primary and oligometastatic lung tumors with stereotactic body radiotherapy (SBRT). The term "oligometastasis" is used to indicate a small number of metastases limited to an organ. We evaluated our clinical experience of SBRT for oligometastatic lung tumors. METHODS AND MATERIALS: A total of 34 patients with oligometastatic lung tumors were included in this study. The primary involved organs were the lung (n = 15), colorectum (n = 9), head and neck (n = 5), kidney (n = 3), breast (n = 1), and bone (n = 1). Five to seven, noncoplanar, static 6-MV photon beams were used to deliver 48 Gy (n = 18) or 60 Gy (n = 16) at the isocenter, with 12 Gy/fraction within 4-18 days (median, 12 days). RESULTS: The overall survival rate, local relapse-free rate, and progression-free rate at 2 years was 84.3%, 90.0%, and 34.8%, respectively. No local progression was observed in tumors irradiated with 60 Gy. SBRT-related pulmonary toxicities were observed in 4 (12%) Grade 2 cases and 1 (3%) Grade 3 case. Patients with a longer disease-free interval had a greater overall survival rate. CONCLUSION: The clinical result of SBRT for oligometastatic lung tumors in our institute was comparable to that after surgical metastasectomy; thus, SBRT could be an effective treatment of pulmonary oligometastases.

Interinstitutional variations in planning for stereotactic body radiation therapy for lung cancer.

PURPOSE: The aim of this study was to assess interinstitutional variations in planning for stereotactic body radiation therapy (SBRT) for lung cancer before the start of the Japan Clinical Oncology Group (JCOG) 0403 trial. METHODS AND MATERIALS: Eleven institutions created virtual plans for four cases of solitary lung cancer. The created plans should satisfy the target definitions and the dose constraints for the JCOG 0403 protocol. RESULTS: FOCUS/XiO (CMS) was used in six institutions, Eclipse (Varian) in 3, Cadplan (Varian) in one, and Pinnacle3 (Philips/ADAC) in one. Dose calculation algorithms of Clarkson with effective path length correction and superposition were used in FOCUS/XiO; pencil beam convolution with Batho power law correction was used in Eclipse and Cadplan; and collapsed cone convolution superposition was used in Pinnacle3. For the target volumes, the overall coefficient of variation was 16.6%, and the interinstitutional variations were not significant. For maximal dose, minimal dose, D95, and the homogeneity index of the planning target volume, the interinstitutional variations were significant. The dose calculation algorithm was a significant factor in these variations. No violation of the dose constraints for the protocol was observed. CONCLUSION: There can be notable interinstitutional variations in planning for SBRT, including both interobserver variations in the estimate of target volumes as well as dose calculation effects related to the use of different dose calculation algorithms.

Aortic valve replacement after coronary artery bypass grafting with the in situ right gastroepiploic artery to the occluded right coronary artery using a temporary vein graft for cardioplegia.

BACKGROUND: The operation of aortic valve replacement (AVR) after CABG is a technically challenging procedure in respect to dissection of living grafts from its surrounding tissue, myocardial protection, and so on, especially that procedure to patients with living in situ functional arterial grafts to occluded native coronary arteries has a special problem in regard to myocardial protection because myocardial blood supply originates from various arteries including the left internal thoracic artery (LITA), the right internal thoracic artery (RITA), and the right gastroepiploic artery (GEA); hence, adequate myocardial protection should be fastidiously considered. CASE PRESENTATION: A 68-year-old woman, who underwent CABG comprised of the in situ LITA to the LAD, the in situ GEA to the RCA, and the saphenous vein graft (SVG) to the obtuse marginal branch of the left circumflex artery (LCX) to the triple vessel coronary disease 9 years before, was referred to our hospital due to the aortic valve stenosis. CONCLUSION: We successfully underwent an aortic valve operation to a patient with a functioning LITA to the occluded left anterior descending artery and a GEA to the right coronary artery (RCA) by using a temporary vein graft to the RCA for the infusion of cardioplegic solution in addition to the conventional antegrade and retrograde cardioplegic infusions with ice slush topical cooling.

The Use of External-beam Radiotherapy for Muscle-invasive Bladder Cancer in Elderly or Medically-fragile Patients.

AIM: To evaluate the clinical results of external-beam radiotherapy (EBRT) for muscle-invasive bladder cancer (MIBC) in elderly or medically-fragile patients. PATIENTS AND METHODS: Twenty-five consecutive patients with MIBC (cT2-4N0-1M0) receiving EBRT were retrospectively analyzed. Their median age was 82 years. Radiotherapy median dose was 60 Gy administered in 30 fractions. RESULTS: Median follow-up period was 14.7 months. Median overall survival (OS) and progression-free survival (PFS) were 14.7 months and 7.8 months, respectively. The OS, cause-specific survival (CSS), and PFS rates at 1-year were 56.0%, 68.5%, and 40.0%, respectively. The local progression-free rates (LPFR) at 6 months and 1 year were 89.3% and 59.5%, respectively. Performance status 3 was a significantly unfavorable factor for OS, CSS, and progression-free survival; clinical N stage was a significantly unfavorable factor for progression-free survival; and lower irradiation dose (≤50.4 Gy) was a significantly unfavorable factor for LPFR. CONCLUSION: EBRT for elderly or medically-fragile patients is feasible, and achieves acceptable local progression-free status.

[Stereotactic body radiotherapy (SBRT)].

The techniques of three-dimensional conformal radiotherapy (3 D-CRT) and patient immobilization have recently been developed, enabling us to focus high doses on the target with relatively less irradiation of normal tissues. In radiotherapy for solitary lung tumors, the local control may be safely improved by delivering a higher dose at only the target volume using these techniques. Recently, several clinical studies on stereotactic body radiotherapy (SRT) using the 3 D-CRT technique for solitary lung tumors have been reported. The single dose used is 10-15 Gy, and the total sessions are three to five. The local control rate is more than 90% and complication rates are very low. Therefore, this treatment is a promising new non-invasive treatment for early stage lung cancer. A multi-institutional clinical study, JCOG 0403, in now underway.

Treatment planning of stereotactic radiotherapy for solitary lung tumor.

PURPOSE: To analyze the stereotactic radiotherapy (SRT) plans in terms of internal target volume (ITV) and organs at risk (OARs). METHODS AND MATERIALS: Treatment planning and dose distributions were analyzed using dose-volume histograms (DVHs) of ITV and OARs in 37 patients, who were treated for a solitary lung tumor with SRT. The stereotactic body frame (SBF) was used for immobilization and accurate setup. Prescription dose was 48 Gy in four fractions at the isocenter. RESULTS: Use of SBF limits the extent of the noncoplanar beam directions to prevent a collision with the Linac gantry. DVH analyses showed that the homogeneity index, defined as the ratio of maximum and minimum dose to ITV, ranged from 1.03 to 1.25 (mean, 1.12). The volume irradiated with 20 Gy or more (V(20)) of the lung ranged from 0.3 to 11.6% (mean, 4.4%) of the whole lung volume. The maximum dose to the other OARs ranged from 0 to 11.8 Gy (mean, 0.5-2.7) per fraction. No clinically significant complications were encountered. CONCLUSIONS: Despite the limitation of the beam arrangement, a homogeneous target dose distribution, while avoiding high doses to normal tissues, was obtained.

Clinical outcomes of a phase I/II study of 48 Gy of stereotactic body radiotherapy in 4 fractions for primary lung cancer using a stereotactic body frame.

PURPOSE: To evaluate the clinical outcomes of 48 Gy of three-dimensional stereotactic radiotherapy in four fractions for treating Stage I lung cancer using a stereotactic body frame. METHODS AND MATERIALS: Forty-five patients who were treated between September 1998 and February 2004 were included in this study. Thirty-two patients had Stage IA lung cancer, and the other 13 had Stage IB lung cancer where tumor size was less than 4 cm in diameter. Three-dimensional treatment planning using 6-10 noncoplanar beams was performed to maintain the target dose homogeneity and to decrease the irradiated lung volume >20 Gy. All patients were irradiated using a stereotactic body frame and received four single 12 Gy high doses of radiation at the isocenter over 5-13 (median = 12) days. RESULTS: Seven tumors (16%) completely disappeared after treatment (CR) and 38 tumors (84%) decreased in size by 30% or more (PR). Therefore, all tumors showed local response. During the follow-up of 6-71 (median = 30) months, no pulmonary complications greater than an National Cancer Institute-Common Toxicity Criteria of Grade 3 were noted. No other vascular, cardiac, esophageal, or neurologic toxicities were encountered. Forty-four (98%) of 45 tumors were locally controlled during the follow-up period. However, regional recurrences and distant metastases occurred in 3 and 5 of T1 patients and zero and 4 of T2 patients, respectively. For Stage IA lung cancer, the disease-free survival and overall survival rates after 1 and 3 years were 80% and 72%, and 92% and 83%, respectively, whereas for Stage IB lung cancer, the disease-free survival and overall survival rates were 92% and 71%, and 82% and 72%, respectively. CONCLUSION: Forty-eight Gy of 3D stereotactic radiotherapy in 4 fractions using a stereotactic body frame is useful for the treatment of Stage I lung tumors.

Haemostatic profile of small children during and following cardiopulmonary bypass.

OBJECTIVE: We evaluated changes of the haemostatic system during pediatric cardiac surgery during and after cardiopulmonary bypass (CPB). METHOD: Twenty-five children under 15 kg of body weight undergoing open-heart surgery were divided into three groups; 9 patients (Group A), no bank blood was used throughout the surgery; 8 patients (Group B), packed red cells were used in the priming of CPB circuit; 8 patients (Group C) in cyanotic condition, for whom surgery was performed without bank blood. CPB caused a significant decrease of platelet counts in all three groups, the levels of which remained similar next morning. RESULTS: Platelet counts decreased more significantly in Group C (59+/-27 k/mm3) than in Group A (119+/-42 k/mm3) and B (104+/-27 k/mm3). Platelet function-platelet activating factor test (HemoSTATUS) did not significantly decrease throughout the perioperative period in Group A. HemoSTATUS value decreased during CPB and recovered after CPB in Group B and C. Prothrombin time international ratio (PT-INR) and activated partial thromboplastin time were significantly prolonged just after CPB and recovered until next morning in all three groups. PT-INR was more prolonged in Group C (2.92+/-0.62) than in Group A (2.08+/-0.27) and B (2.42+/-0.42). There was no significant difference in postoperative bleeding for the first 12 hours among the three groups. CONCLUSION: Although extreme hemodilution during CPB significantly impairs the coagulation and platelet system, these changes are usually transient and tolerable with minimal postoperative hemorrhage. However, a prolonged CPB and preoperative cyanotic condition may induce a critical decrease of platelet counts and increase postoperative bleeding.

Primary tissue failure of the Freestyle stentless aortic root bioprosthesis.

We present a case of early tissue failure of the Medtronic Freestyle stentless bioprosthesis used in the aortic position which led to reoperation 27 months after implantation. Almost one half of the left coronary cusp of the prosthetic valve had torn away along the annulus. The tear started from the left-non coronary commissure and reached the midpoint of the base of the left coronary cusp. The prosthetic valve was easily excised and replaced with a new mechanical valve. There was no sign of calcification or vegetation in the excised valve. The cause of the valve dysfunction was thought to be primary tissue failure. Long-term function of the Freestyle stentless valve should be carefully followed up.

Effect of biventricular pacing therapy in patients with dilated cardiomyopathy with severe congestive heart failure.

OBJECTIVES: Biventricular pacing (BVP) therapy has recently emerged as an effective treatment for patients with moderate to severe congestive heart failure (CHF) and ventricular asynchrony all over the world. However, this therapy is not yet available in Japan. We evaluated the effects of BVP in patients with severe CHF due to dilated cardiomyopathy (DCM). SUBJECTS: Four patients with medically refractory severe CHF due to DCM in New York Heart Association functional class III or IV heart failure underwent BVP therapy. We combined the implantation of the left ventricular (LV) epicardial lead via small thoracotomy following right atrial and ventricular intravenous leads under general anesthesia. We evaluated to determine whether improvements of ventricular function, ventricular size, mitral regurgitation, functional status, frequency of hospitalization, and quality of life were associated with BVP therapy. RESULTS: BVP improved LV systolic function, decreased LV size and mitral regurgitation, and shortened prolonged QRS interval. The patients' symptoms, exercise tolerance, frequency of hospitalization, and quality of life were also dramatically improved by BVP. Furthermore, combination of BVP and oral administration of amiodarone significantly prevented recurrence of ventricular tachycardia and paroxysmal atrial fibrillation, and maintained sinus rhythm for a long period. CONCLUSIONS: In view of these findings, BVP therapy may contribute to the development of new therapeutic method for patients with severe CHF due to DCM.

One-stage operation for esophageal perforation of a thoracic aortic aneurysm.

The patient was a 65-year-old man. Preoperative computed tomography showed a ruptured thoracic aortic aneurysm that formed a submucosal hematoma in the thoracic esophagus with perforation near the esophageal-cardiac junction. A one-stage operation was performed. The aortic arch and proximal descending aorta were replaced with rifampicin-soaked synthetic grafts, followed by subtotal esophagectomy with primary reconstruction using a gastric tube. His early postoperative course was uneventful, and he started oral intake on postoperative day (POD) 15; however, dysphagia occurred on POD 20, and an esophageal fistula and mediastinitis developed more than 1 month after the operation. The patient recovered from mediastinitis after 4 months of mediastinal drainage and administration of antibiotics. Thus, a one-stage operation for esophageal perforation of a ruptured thoracic aortic aneurysm with primary esophageal reconstruction is possible in selected patients. Care must be taken to avoid postoperative compression of the reconstructed esophagus by a mediastinal hematoma.
