RESUMO
BACKGROUND: The Bristow coracoid transfer procedure is a reliable technique for treating anterior shoulder instability in patients with large glenoid bone loss or those involved in collision sports. However, its success is marred by its inferior bone union rate of the coracoid process as compared to the Latarjet procedure. This study aimed to evaluate whether arthroscopic confirmation of the secured coracoid fixation during the Bristow procedure improves the bone union rate and clinical outcomes as compared to the open procedure. METHODS: We retrospectively reviewed 104 rugby players (n = 111 shoulders) who underwent an open (n = 66 shoulders) or arthroscopy (AS)-assisted (n = 45 shoulders) Bristow procedure at our center from 2007 to April 2019. In the AS-assisted group, the screw fixation and coracoid stability and contact were confirmed under arthroscopic visualization. Graft union was evaluated through computed tomography at 3 months, 6 months, and 1 year postoperatively. Patient-reported outcome measures were assessed based on the American Shoulder and Elbow Surgeons score, Rowe score, and satisfaction rate. Recurrence, the rate of return to play (RTP), and the frequency of pain after RTP were also assessed. RESULTS: The mean follow-up period was 73.5 (range: 45-160) months for the open group and 32.3 (range: 24-56) months for the AS-assisted group. In the former, the rates of bone union were 50%, 72.7%, and 88.9% at 3 months, 6 months, and 1 year, respectively. In contrast, the AS-assisted group had significantly greater bone union rates-88.9%, 93.3%, and 95.6% at 3 months, 6 months, and 1 year, respectively. Both groups showed significant improvement in the American Shoulder and Elbow Surgeons and Rowe scores compared to preoperative values as well as high satisfaction rates (open: 92%; AS-assisted: 95.7%). There were no statistically significant differences in the recurrence and RTP rates as well as the frequency of pain after RTP between the 2 groups. CONCLUSION: The AS-assisted procedure allows early and high bone healing without compromising the clinical outcomes.
RESUMO
PURPOSE: The present study analyzed the outcomes of our experience with abdominal aortic aneurysm (AAA) repair over 20 years using endovascular aortic repair (EVAR) with commercially available devices or open aortic repair (OAR) and reviewed our surgical strategy for AAA. METHODS: From 1999 to 2019, 1077 patients (659 OAR, 418 EVAR) underwent AAA repair. The OAR and EVAR groups were compared retrospectively, and a propensity matching analysis was performed. RESULTS: EVAR was first introduced in 2008. Our strategy was changed to an EVAR-first strategy in 2010. Beginning in 2018, this EVAR-first strategy was changed to an OAR-first strategy. After propensity matching, the overall survival in the OAR group was significantly better than that in the EVAR group at 10 years (p = 0.006). Two late deaths due to AAA rupture were identified in the EVAR group, although there were no significant differences between the OAR and EVAR groups with regard to the freedom from AAA-related death at 10 years. The rate of freedom from aortic events at 10 years was significantly higher in the OAR group than in the EVAR group (p < 0.0001). CONCLUSION: The rates of freedom from AAA-related death in both the OAR and EVAR groups were favorable, and the rate of freedom from aortic events was significantly lower in the EVAR group than in the OAR group. Close long-term follow-up after EVAR is mandatory.

An impending paradoxical embolism (IPDE) is seldom observed in clinical practice. We report a case of IPDE in a 67-year-old female with severe dyspnea and hypotension, which was detected and successfully treated with emergent cardiac surgery. The optimal treatment is still controversial. We believe that emergent surgery always should be considered in patients with IPDE.
RESUMO
Intracranial artery occlusion due to a foreign body is a complication associated with cardiac surgery that is treated by various techniques. However, little is known about appropriate strategies for symptomatic intracranial artery stenosis due to an unknown embolic source. We reported a case of middle cerebral artery (MCA) stenosis after mitral valve repair (MVR) for infective endocarditis (IE). An 80-year-old man presented with right hemiplegia. MR angiography findings were normal, and diffusion-weighted imaging revealed subtle ischemic change in the left MCA territory. The patient was diagnosed with cardioembolic stroke owing to IE and performed MVR. Four days later, he suddenly presented with consciousness disorder and left hemiplegia. Computed tomography (CT) confirmed a very low-density area within the right MCA. MR angiography revealed right MCA stenosis, which corresponded to the low-density area on CT images. Diffusion-weighted imaging revealed new ischemic change in the right MCA territory. Angiography confirmed an irregular stenosis at the right M2 with antegrade blood flow, and the hemiplegia resolved during angiography. Conservative therapy was performed; however, the resting 123 I-IMP-single photon emission CT revealed moderate perfusion defect in the right MCA territory, and transient left hemiplegia appeared every few days. Therefore, 19 days after the initial transient ischemic attack, the patient was performed superficial temporal artery-MCA anastomosis, and the patient responded with a good clinical course without recurrence of the ischemic symptoms. This strategy may be a safe and effective treatment for symptomatic intracranial artery stenosis due to an unknown embolic source.
RESUMO
Objective: We sought to investigate the efficacy of human bone marrow mesenchymal stem/stromal cell (hBM-MSC) in a murine spinal cord ischemia/reperfusion (SCIR) model. Methods: C57BL/6J mice were subjected to SCIR by crossclamping the aortic arch and left subclavian artery for 5.5 minutes. Two hours after reperfusion, hBM-MSCs (hBM-MSC group) or phosphate-buffered saline (control group) were intravenously injected without immunosuppressant. Hindlimb motor function was assessed until day 28 after reperfusion using the Basso Mouse Scale (BMS). The lumbar spinal cord was harvested at hour 24 and day 28, and the histologic number of NeuN-positive motor neurons in 3 cross-sections of each lumbar spinal cord and the gene expression were evaluated. Results: BMS score was 0 throughout the study period in all control mice. BMS score was significantly greater in the hBM-MSC group than the control group from hour 8 (P < .05) to day 28 (P < .01). The numbers of motor neurons at hour 24 (P < .01) and day 28 (P < .05) were significantly preserved in the hBM-MSC group than the control group. mRNA expression levels of proinflammatory cytokines were significantly lower (P < .05), and those of insulin-like growth factor-1 (P < .01) and proangiogenic factors (P < .05) were significantly greater in the hBM-MSC group than the control group at hour 24. Conclusions: hBM-MSC therapy may attenuate SCIR injury by preserving motor neurons, at least in part, through inhibition of proinflammatory cytokines and upregulation of proangiogenic factors in the reperfusion-injured spinal cord.
RESUMO
We present an extremely rare case of mitral Ebstein's anomaly that resulted in severe mitral regurgitation (MR). A 41-year-old woman with a history of tuberous sclerosis underwent surgery. Preoperatively, it was assumed that MR had occurred due to leaflet tethering related to left ventricular posterior wall motion asynergy due to a scarred rhabdomyoma. However, surgical inspection revealed a dysplastic posterior leaflet adhering to the ventricular wall, which was completely covered by the endocardium. Both congenital mitral Ebstein's anomaly and acquired wall motion abnormality due to a scarred rhabdomyoma may have contributed to the development of severe MR in this case.

OBJECTIVES: Valve repair for aortic insufficiency (AI) requires a tailored surgical approach determined by the leaflet and aortic disease. In this study, we used a repair-oriented system for the classification of AI, and we elucidated long-term outcomes of aortic root reimplantation with this classification system. METHODS: From 1999 to 2018, a total of 197 patients underwent elective reimplantation (mean age: 52.7 ± 17.7 years; 80% male). The aortic valve was tricuspid in 143 patients, bicuspid in 51 patients and quadricuspid in 3 patients. A total of 93 patients had type I AI (aortic dilatation), 57 patients had type II AI (cusp prolapse) and 47 patients had type III AI (restrictive). In total, 104 of the 264 patients (39%) had more than 1 identified mechanism. RESULTS: In-hospital mortality was 0.5% (1/197). Mid-term follow-up (mean follow-up duration: 5.5 years) revealed a late mortality rate of 4.2% (9/197). Aortic valve reoperation was performed on 16 patients (8.0%). Rates of freedom from aortic valve replacement and freedom from aortic valve-related events at 10 years of follow-up were 87.0 ± 4.0% and 60.6 ± 6.0%, respectively; patients with type Ib AI (98.3 ± 1.7%; 80.7 ± 7.5%) had better outcomes than patients with type III AI (59.6 ± 15.6%; 42.2 ± 13.1%, P = 0.01). In patients with types II and III AI who had bicuspid aortic valves, rates of freedom from aortic valve-related events at 5 years of follow-up were 95.2 ± 4.7% and 71.7 ± 9.1%, respectively (P = 0.03). CONCLUSIONS: This repair-oriented system for classifying AI could help to predict the durable aortic valve repair techniques. Patient selection according to the classification is particularly important for long-term durability. CLINICAL TRIAL REGISTRATION NUMBER: B190050.

OBJECTIVE: We present our open surgical strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome. METHODS: Between October 1999 and December 2017, 82 patients with Marfan syndrome underwent 118 aortic repairs. We divided the aorta into 4 segments for categorization: (1) the aortic root, (2) aortic arch, (3) descending thoracic, and (4) abdominal aorta. Procedures were categorized according to the types of surgery. Staged repair was defined as a subsequent operation on a different segment of the aorta after initial repair (n = 111, 94.1%), and reoperation was defined as an operation on the same segment (n = 7, 5.9%). RESULTS: The mean age at initial operation was 41.7 ± 14.9 years. Staged repairs included aortic root replacement (n = 42, 36%), total arch replacement (n = 11, 9.3%), combined aortic root and total arch replacement (n = 13, 11%), descending aorta replacement (n = 4, 3.4%), thoracoabdominal aortic repair (n = 36, 31%), and extensive arch-descending or thoracoabdominal repair (n = 5, 4.2%). Four patients received 3 staged repairs. Operative mortality was 0.8% (1/118). Stroke occurred in 1.7% (2/118), and spinal cord injury occurred in 1.7% (2/117). Overall survival was 95.8 ± 2.4% at 10-years. Twenty-four patients underwent replacement of the whole aorta after 2.5 ± 3.8 years following initial repair. CONCLUSIONS: Our strategies for staged replacement of the thoracic and thoracoabdominal aorta in patients with Marfan syndrome resulted in excellent early- and long-term outcomes.

OBJECTIVE: This study investigated the mid-term outcomes of simultaneous mitral valve repair in patients with mitral regurgitation (MR) and concomitant annulo-aortic ectasia. METHODS: The study included 26 patients with MR and annulo-aortic ectasia [mean age 46.0 ± 19.9 (10-86) years] who underwent simultaneous mitral valve repair between January 2007 and March 2018. Of these 26 patients, 11 (42.3%) were diagnosed with Marfan syndrome and 10 (38.5%) with Barlow's disease. All patients underwent complete ring annuloplasty; a semi-rigid ring was used in 14 (53.8%) and a semi-flexible ring (anterior-flexible) in 12 patients (46.2%). All patients underwent valve-sparing root replacement using the reimplantation technique. RESULTS: The overall 3-year survival rate was 95.7 ± 4.3%. The 3-year freedom from > moderate MR rate was 94.7 ± 5.1%, and the 3-year freedom from > moderate aortic regurgitation (AR) rate was 86.7 ± 7.3%. The 3-year freedom from reoperation rate was 100%. The 3-year freedom from > moderate MR rate was 100% in the semi-rigid ring group and 85.7 ± 13.2% in the semi-flexible ring group (log-rank test, p = 0.5371). The 3-year freedom from > moderate AR rate was 100% in the semi-rigid ring group and 72.9 ± 16.5% in the semi-flexible ring group (log-rank test, p = 0.0815). CONCLUSIONS: Simultaneous mitral valve repair in patients with MR and concomitant annulo-aortic ectasia showed favorable mid-term outcomes.

Pseudocoarctation of the aorta is an uncommon congenital condition and cases in octogenarians are rare. The patient was an 83-year-old woman in whom the condition was accidentally detected. Computed tomography showed a hypoplastic aortic arch, pseudocoarctation and descending aortic aneurysm with severe atherosclerotic calcification. We performed the distal arch and the descending aortic replacement with reconstruction of the left subclavian artery using hypothermic circulatory arrest via left posterolateral thoracotomy. Histologically, the aortic tissue showed myxomatous changes. We report a case of successful treatment of the hypoplastic aortic arch and pseudocoarctation of the aorta in an octogenarian.

OBJECTIVES: This study aimed to analyse the early patency rate and long-term outcomes of reattached segmental intercostal arteries using graft interposition, single-cuff anastomosis or island reconstruction. METHODS: We selected 172 consecutive patients who underwent open surgery for the thoracoabdominal aorta with reattachment of segmental arteries between October 1999 and March 2018. The early patency of segmental arteries was analysed using enhanced computed tomography. Segmental arteries were reconstructed using graft interposition (n = 111), single-cuff anastomosis (n = 38) or island reconstruction (n = 23). RESULTS: The hospital mortality was 6.4%. Twenty patients developed spinal cord ischaemic injury (permanent, n = 12 or transient, n = 8). Spinal cord injury was found in 16, 3 and 1 patients in the graft interposition, single-cuff anastomosis and island reconstruction groups, respectively. Overall, 475 segmental arteries were reattached (mean number per patient 2.8 ± 1.3). The overall early patency rate was 63.4%. The patency rates in island reconstruction (91.2%) and single-cuff anastomosis (77.1%) were significantly better than that in graft interposition (54.0%; P < 0.01). However, 6 patients with island reconstruction of segmental arteries had an aneurysm formation at the intercostal artery reconstruction site, of whom 4 patients underwent reoperation during follow-up. None of the patients with graft interposition or single-cuff reattachment had a patch aneurysm in segmental arteries. CONCLUSIONS: Island reconstruction and single-cuff anastomosis might offer better patency rates and prevent spinal cord ischaemic injury than graft interposition. Because some patients with island reconstruction required reoperation for patch aneurysms in segmental arteries, single-cuff anastomosis is preferable in terms of early- and long-term outcomes.
RESUMO
OBJECTIVES: The aim of this study was to evaluate the fate of the downstream aorta following open aortic repair for acute DeBakey type I aortic dissection comparing total arch replacement (TAR) with the elephant trunk (ET) technique versus non-total arch replacement (non-TAR). METHODS: From October 1999 to December 2016, 267 patients underwent open repair for acute DeBakey type I aortic dissection. A tear-oriented strategy was mainly used to determine the extent of graft replacement. Hospital mortality was 10.0% (12/120 patients) in the TAR group and 17.0% (25/147 patients) in the non-TAR group (P = 0.070). Late outcomes were compared in 230 hospital survivors (TAR: n = 108 and non-TAR: n = 122). Mean follow-up was 6.5 ± 4.6 years. The aortic diameters were measured at 4 levels, across 6 time points using computed tomography. RESULTS: Freedom from additional aortic surgery for distal dilation was significantly better in the TAR group than the non-TAR group (TAR: 97.5 ± 1.8% at 5 years and non-TAR: 88.2 ± 3.4% at 5 years, P = 0.045). Freedom from a distal aortic event was also significantly better in the TAR group compared with the non-TAR group (TAR: 97.2 ± 1.6% at 5 years and non-TAR: 80.7 ± 4.2% at 5 years, P = 0.013). In the non-TAR group, the aortic arch diameter significantly increased (P < 0.001). Significant aortic remodelling occurred at the proximal descending aorta in the TAR with ET group (P < 0.001). CONCLUSIONS: The TAR with ET reduced the need for additional distal aortic repair compared to non-TAR. TAR with ET prevented unfavourable aortic growth in both the aortic arch and the proximal descending aorta.

BACKGROUND: We report early and midterm outcomes of elderly patients who underwent valve-sparing root replacement (VSRR) compared with younger patients and those with Bentall procedure. METHODS: From October 1999 to October 2017, 73 patients greater than or equal to 65 years of age who underwent VSRR procedure were assigned as group S. Two hundred thirty-two VSRR patients who were between 15 and 64 years of age were assigned as group Y. Forty-five patients greater than or equal to 65 years of age who underwent Bentall procedure were assigned as group R. Preoperative grades of aortic regurgitation were 3.4 of 4 in group S, 3.1 of 4 in group Y, and 3.3 of 4 in group R (p = 0.07). RESULTS: Hospital mortality was found in 1 (1.4%) patient in group S, 3 (6.7%) in group R, and 2 (0.9%) in group Y. Postoperative survival at 5 years was 88.5% in group S, 98.7% in group Y, and 82.4% in group R (p < 0.01). Freedom from more than mild aortic regurgitation at 5 years was 81.0% in group S and 85.4% in group Y. Follow-up echocardiography disclosed an effective aortic valve orifice area of 1.76 cm2 in group R, 2.40 cm2 in group Y, and 2.41 cm2 in group S (p < 0.01), and peak pressure gradient across the aortic valve was 17.7 mm Hg in group R, 13.6 mm Hg in group Y, and 10.8 mm Hg in group S (p < 0.01). CONCLUSIONS: Similar early and late outcomes were achieved in elder VSRR patients compared with younger patients. A better postoperative valve performance was demonstrated in VSRR patients than patients undergoing valve-replacement.

OBJECTIVES: The aim of this study was to evaluate the early and long-term outcomes of our multidisciplinary strategy for treating deep sternal wound infection after aortic grafting, which consisted of debridement by a plastic surgeon, negative pressure wound therapy with continuous irrigation and chest wall reconstruction. METHODS: We performed a retrospective analysis of 18 patients who had a deep sternal wound infection following aortic grafting through a median sternotomy between January 2009 and December 2017. All patients had organisms cultured from mediastinal tissue within 2 months from the initial aortic surgery. The prosthetic grafts were exposed in 15 patients during resternotomy. Our protocol involved repeat debridement and negative pressure wound therapy with continuous irrigation twice a week until the results of the culture were negative and chest wall reconstruction was complete. RESULTS: The mean duration from primary aortic surgery to resternotomy was 23.7 ± 15.9 days. Except for 1 patient, 17 patients underwent chest wall reconstruction. The mean duration from resternotomy to chest wall reconstruction was 31.1 ± 28.0 days. The hospital mortality rate was 16.7% (3 patients), although no patients died of wound-related causes. The mean follow-up period was 2.9 ± 2.5 years. Overall survival was 69.6 ± 11.4% at 1 year and 54.2 ± 13.3% at 5 years. Freedom from reoperation for reinfection was 94.4 ± 5.4% at 5 years. CONCLUSIONS: Our wound care strategy achieved acceptable early and late survival in patients who had deep sternal wound infection following aortic grafting. This strategy may benefit those who experience this devastating complication.

OBJECTIVE: Presenting our experience of direct perfusion of the carotid artery in patients with brain malperfusion secondary to acute aortic dissection. PATIENTS: Among 381 patients who underwent aortic repair for acute type A aortic dissection from October 1999 to August 2017, brain malperfusion was recognized in 50 patients. Nine patients had direct perfusion of the right carotid artery in patients with brain malperfusion secondary to acute aortic dissection. Age at surgery was 65.7 ± 13.5 years and three patients were male. Preoperative consciousness level was alert in one patients, drowsy in six, and coma in two. Five patients had preoperative hemiplegia. All patients showed a blood pressure difference between the upper extremities and eight patients showed more than 15% difference of rSO2. Seven patients had a temporary external active shunt from the femoral artery to the right common carotid artery preoperatively. Two patients had direct perfusion to the right common carotid artery during cardiopulmonary bypass or in the intensive care unit after surgery because of a sudden decrease of rSO2 and cessation of carotid artery flow. Antegrade cerebral perfusion was used in all patients. Total arch replacement was performed in six patients and hemiarch in three. RESULTS: The hospital mortality was 33% (3 patients). Causes of death were huge hemispheric brain infarction or anoxic brain damage in two patients and myocardial infarction in one. The postoperative neurological outcome was alert in four, hemiplegia in two, and coma in three, but five patients showed some improvement of neurological signs. CONCLUSION: Aggressive direct reperfusion of the carotid artery before the aortic repair may reduce neurological complications in patients with preoperative brain malperfusion secondary to acute aortic dissection.

We present a rare case of common carotid artery with acute type A aortic dissection. A 72-year-old woman underwent emergent aortic arch repair using Antegrade selective cerebral protection. Bottom-tapped cannulae were inserted into three orifices of arch vessels, however, regional cerebral oxygen saturation decreased after rewarming. We found that arch branches were in order from front to back, right subclavian artery, common carotid trunk, and left subcravian artery. The patient complicated stroke in the right middle cerebral artery.

Despite advances in emergency care and the emergent transportation system, cardiac and aortic ruptures after blunt trauma are associated with high mortality and morbidity. We present a rare case of a 70-year-old man with a ruptured left atrial basal appendage and distal aortic arch after sustaining blunt trauma to the chest during a motor vehicle accident. The patient was transported to our hospital in a state of shock and taken directly to the operating room. Hybrid treatment was performed, including surgical repair of the left atrium under cardiopulmonary bypass and thoracic endovascular aortic repair, was performed. The patient fully recovered without any complications.

BACKGROUND: This study aimed to evaluate the early and long-term outcomes of graft replacement of Kommerell diverticulum and in situ reconstruction of aberrant subclavian arteries in adults. METHODS: Seventeen patients, 6 symptomatic and 11 with right aortic arch, underwent open repair of Kommerell diverticulum from October 1999 to September 2017. Two of these patients underwent open surgical treatment of a ruptured aneurysm. Surgical indications were dilatation of Kommerell aneurysm (n = 9), the presence of a nondissecting aneurysm with Kommerell diverticulum (n = 6), acute type A aortic dissection (n = 1), and complicated acute type B aortic dissection (n = 1). Ten patients underwent total arch replacement and descending aorta replacement through a thoracotomy. Five patients underwent arch replacement and in situ reconstruction through a median sternotomy. All patients except 1 also underwent in situ reconstruction of their aberrant subclavian artery. RESULTS: In-hospital death occurred in 1 patient (5.9%), who underwent total arch replacement for a ruptured aneurysm. Permanent neurologic deficit did not occur in any patient, whereas transient neurologic deficit occurred in 2 patients (11.8%). Five- and 10-year survival rates were 85.2 ± 9.8% and 75.8 ± 12.5%, respectively. There was no symptom recurrence or stenosis of the reconstructed subclavian arteries. CONCLUSIONS: Early outcomes of graft replacement of Kommerell diverticulum and in situ aberrant subclavian artery reconstruction were acceptable. As for long-term outcomes, symptomatic improvement and an excellent patency rate among reconstructed aberrant subclavian arteries suggest that in situ surgical repair is an effective treatment option.
