RESUMO

A surgical intervention for type A acute aortic dissection is the only effective method of treatment making it possible to prevent the development of life-threatening complications and to attain clinical recovery of the patient. Supracoronary replacement of the ascending aorta and the proximal portion of the aortic arch is considered to be the classical and most commonly used method of an open operative intervention. On the one hand, it is technically the simplest and shortest operation, and on the other, this surgical technique is often accompanied by long-term proximal and distal complications, and first of all those caused by a persistent false lumen. The accumulated surgical experience and contemporary operative techniques, as well as advances of intensive therapy in treatment of type A acute aortic dissection make it possible to currently perform more extensive primary resections in order to improve the remote results. Total aortic arch replacement, including the use of the 'frozen elephant trunk' technique leads to fast thrombosis of the false lumen, preventing progression of the disease of the thoracic aorta and promoting its positive remodelling. The article describes the perioperative therapeutic policy accepted and pursued in our medical facility, also presenting the authors' opinion on the role and place of the 'frozen elephant trunk' technique in rendering medical care for patients with type A acute aortic dissection.

RESUMO

The article deals with the results of successful surgical management of a male patient with a ruptured thoracic aortic aneurysm, posing particular problems as to deciding upon the scope and stages of surgical reconstruction, accompanied by describing the dynamics of clinical and diagnostic parameters, as well as the main events of the postoperative period. This clinical case report was characterized by additional difficulties due to the occurrence of subtotal haemothorax. Also presented herein is a set of comprehensive measures making it possible to successfully complete open reconstruction of the thoracic portion of the aorta and to achieve a satisfactory outcome both during the in-hospital period and within one-year follow up. Besides, elucidated is the state-of-the-art of this problem in the world literature.

RESUMO

An aorto-oesophageal fistula is a rare but life-threatening pathological condition developing on the background of diseases of the aorta and oesophagus, as well as after surgical interventions on the aorta. The article deals with a clinical case report regarding management of a patient presenting with an aorto-oesophageal fistula resulting from a thoracic artery aneurysm. The main clinical manifestations of the diseases included dysphagia (due to oesophageal obstruction caused by thrombotic masses of the aneurysm) and the occurring gastrointestinal haemorrhage. Comprehensive instrumental diagnosis was performed using roentgen examination of the oesophagus, oesophagoscopy, and contrast-enhanced computed tomography of the chest. The obtained findings made it possible to objectively assess the patient's state, to carry out timely treatment in conditions of a surgical hospital, and to avoid severe complications.

RESUMO

Described herein is a clinical case report regarding surgical treatment of a patient presenting with a ruptured Crawford type III thoracoabdominal aortic aneurysm. The patient was subjected to prosthetic repair of the thoracoabdominal aorta by the Coselli technique, as well as reduction of the aneurysmal sac in the thoracic and abdominal portions according to the authors' technique. The operation was carried out with neither connecting the patient to a heart-lung machine nor use of pharmacological protection of the visceral organs. The sutures were removed on postoperative day 12 and the patient was discharged from hospital in a satisfactory condition.

RESUMO

Presented herein is a clinical case report regarding a repeat intervention for a type II dissecting thoracoabdominal aortic aneurysm treated by means of a hybrid technique in a 76-year-old male patient with a single kidney, having 9 years previously endured resection of an aneurysm of the infrarenal aortic portion. The first stage consisted in prosthetic repair of the thoracoabdominal aortic aneurysm by an oblique anastomosis, with the second stage (7 days thereafter) being endoprosthetic repair of the descending thoracic aorta. The findings of check-up computed tomography at 16 months postoperatively demonstrated no negative dynamics.

RESUMO

OBJECTIVES: We examined the spring back force (SBF) in the frozen elephant trunk technique between patients receiving a Matsui-Kitamura stent (M group) or a J Graft Open Stent Graft (J group). METHODS: There were 11 cases in the M group and 10 cases in the J group. For all cases, we performed computed tomography( CT) scan and measured distal arch angle( DAA) and stent graft angle (SGA). RESULTS: There was no difference between groups with regards to patient characteristics. The insertion graft length[155±19 mm (M group) versus 138±17 mm (J group)]was significantly longer in the M group( p<0.05). In the J group, the SGA at 1 and 2 years postoperatively( 105°±18.5° and 114°±19.1°, respectively) were significantly increased compared to that at 1 month postoperatively (99.9°± 18.7°). In addition, the SGA in the J group was significantly larger than that in the M group during the postoperative period. CONCLUSIONS: The SBF in the J group was thought to be significantly larger than that in the M group. SBF was thought to be associated with the stent frame characteristic.

RESUMO

In recent years, re-rupture due to endoleaks after thoracic endovascular aortic repair (TEVAR) for ruptured thoracic aortic aneurysms has become a problem. Hemoptysis has been reported in patients after pneumocentesis. We report a patient who developed delayed hemoptysis not related to endoleak after TEVAR. An 80-year-old male underwent emergent TEVAR due to a ruptured thoracic aortic aneurysm accompanying sudden hemoptysis. Eleven days after the operation, recurrent hemoptysis was noted, but contrast-enhanced computed tomography (CT) revealed no endoleak or re-rupture. Bronchoscopy demonstrated hemorrhage from the left upper lobe. As hemostasis was difficult by conservative treatment, left upper lobectomy was performed. The aortic rupture hole exhibited thrombus, and there was no hemorrhage. On histopathological examination of the resected lung, formation accompanied by severe intra-alveolar fibrosis and cholesterin clefts, and marked foreign body reactions in the interstitium and small blood vessels of the lung were observed. Cholesterol embolism is associated with not only organ ischemia due to microembolism, but also immunological mechanisms. Thus, cholesterol embolism due to aorta-derived cholesterin may have led to the delayed pulmonary hemorrhage. Differentiation from re-rupture due to endoleaks is important.

RESUMO

The fundamental treatment of Stanford type A acute aortic dissection is a lifesaving emergency surgery in our hospital. We perform hemiarch replacement with a focus on entry tear, but an extended surgery is also performed only when resection of the entry tear is difficult. The outcomes of current therapeutic policy, along with the short-term and the long-term outcomes of different sites of entry tear, were examined retrospectively. Three hundred and twenty surgery of Stanford type A acute aortic dissection were performed between 1991 and 2015 at our hospital. Their short-term and long-term outcomes were examined after dividing them into 7 groups according to their entry sites. We also investigated surgical methods and effects of presence/absence of residual entry tear. As a result, overall hospital mortality was 13.1%. There was no significant difference in either shortterm or long-term outcome among the groups. Likewise, no significant difference was observed in the surgical methods or the presence/absence of residual entry tear. Recently, minimally invasive procedures, such as stent-grafting, have been applied to manage the residual entry tear. Therefore, an aggressive extended surgery is no longer inevitable and our current therapeutic policy is considered reasonable.

RESUMO

Recently, thoracic endovascular aortic repair( TEVAR) has emerged as an alternative to open repair. We reported a case of a 92-year-old woman who underwent successful TEVAR for impending rupture of aortic arch aneurysm. The patient presented with back pain. Computed tomography revealed an impending rupture site at the aortic arch and left hemothorax. First, an axilo-axilo-carotid artery bypass was performed, and then 2 thoracic stent grafts were deployed successfully. Her postoperative course was uneventful, and at day 20, she was discharged. Debranching TEVAR is an effective procedure for aortic arch aneurysms in elderly patients.

RESUMO

CASE REPORT: A 64-year-old woman presented to our emergency department during the outbreak of the covid-19 emergency in Italy with syncope, anosmia, mild dyspnoea and atypical chest and dorsal pain. A chest CT scan showed an acute type B aortic dissection (ATBAD) and bilateral lung involvement with ground-glass opacity, compatible with interstitial pneumonia. Nasopharyngeal swabs resulted positive for SARS-CoV-2. For the persistence of chest pain, despite the analgesic therapy, we decided to treat her with a TEVAR. Patient's chest and back pain resolved during the first few days after the procedure. No surgical or respiratory complications occurred and the patient was discharged 14 days after surgery. DISCUSSION: By performing the operation under local anesthesia, it was possible to limit both the staff inside the operatory room and droplet/aerosol release. Since we had to perform the operation in a hemodynamics room, thanks to the limited extension of the endoprosthesis and the good caliber of the right vertebral artery we were able to reduce the risk of spinal cord ischemia despite the lack of a revascularization of the left subclavian artery. CONCLUSIONS: A minimally invasive total endovascular approach allows, through local anesthesia and percutaneous access, to avoid surgical cut down and orotracheal intubation. This, combined with a defined management protocol for infected patients, seems to be a reasonable way to perform endovascular aortic procedures in urgent setting, even in a SARSCoV- 2 positive patient. KEY WORDS: COVID-19, Dissection, TEVAR.

RESUMO

Five years after the first endovascular aortic repair (EVAR), Park et al. reported the first implantation of a fenestrated endoprosthesis. In the meantime, advanced generations of new fenestrated and branched endografts evolved. Endografts for complex pathologies are either so-called "off-the-shelf" grafts with predetermined length, width, diameter and clock position of the branches and fenestrations, predetermined by the manufacturer, "custom-made" grafts which need to be sized and planned individually for patients with specific thoracoabdominal anatomy. Open aortic repair in the treatment of thoracoabdominal aortic aneurysm (TAAA) still remains challenging and is associated with high morbidity and mortality, even in the elective setting. The ongoing development of endovascular treatment modalities, such as fenestrated and branched endovascular aneurysm repair (F-EVAR, B-EVAR), enables less invasive procedures for more challenging aortic pathologies. In recent years, extensive endovascular treatment of the aortic arch to the thoracoabdominal segment has become more and more important, but its outcomes have not been completely evaluated. The aim of this is article is to provide an overview of the currently available endovascular treatment options for complex aortic aneurysms requiring extensive coverage from the aortic arch to the infrarenal aorta.

RESUMO

OBJECTIVE: The objective of this prospective single centre study was to assess whether branches and fenestrations have different outcomes on renal function in the early phase. METHODS: From March 2018 to June 2019, 67 patients who underwent elective fenestrated and branched endovascular aneurysm repair (F/BEVAR) procedures were enrolled in this study. The patients were divided into two groups according to the renal bridging component configuration (fenestration vs. branch). All of them underwent dynamic renal scintigraphy with 99mTc diethylenetriaminepentaacetic acid (DTPA), two weeks pre-operatively, and three months and one year post-operatively. The primary end points were peri-procedural technical success, 30 day major adverse events, differences in glomerular filtration rate (GFR) between the branch and fenestration configurations, and variations between the pre-operative and the post-operative dynamic renal scintigraphy. RESULTS: Overall, 135 kidneys were analysed: 63 in the 32 patients treated with fenestrations, and 72 in the 35 patients treated with branches; the mean GFR on baseline scintigraphy was 58.4 ± 30.9 mL/min in the fenestration group, and 65.1 ± 29.2 mL/min in the branch group. Only kidneys associated with a patent fenestration/branch were included in the split GFR final analysis. The mean total GFR at three month scintigraphy decreased by 6.0 ± 2.9 mL/min in the fenestration group and by 23.4 ± 6.4 mL/min in the branch group. The split GFR decreased by 3.5 ± 0.6 mL/min in the fenestration group, and by 15.4 ± 5.4 mL/min in the branch group. The GFR decrease remained stable at one year. CONCLUSION: In this study, the use of branches for renal arteries during F/BEVAR resulted in a greater decrease in the GFR than in those patients who were treated with fenestrations alone. The scintigraphic alterations were evident at an early phase.

RESUMO

OBJECTIVE: The aim was to describe the outcomes of the Anaconda™ Fenestrated endograft Italian Registry for complex aortic aneurysms (AAAs), unsuitable for standard endovascular aneurysm repair (EVAR). METHODS: Between 2012 and 2018 patients with a proximal neck unsuitable for standard EVAR, treated with the fenestrated Anaconda™ endograft, were prospectively enrolled in a dedicated database. Endpoints were peri-operative technical success (TS) and evaluation of type Ia/b or 3 endoleaks (T1/3 EL), target visceral vessel (TVV) occlusion, re-interventions, and AAA related mortality at 30 days, six months, and later follow up. RESULTS: One hundred twenty seven patients (74 ± 7 years, American Society Anesthesiology (ASA) II/III/IV: 12/85/30) were included in the study in 49 Italian Vascular Surgery Units (83 juxta/para-renal AAA, 13 type IV thoraco-abdominal AAA, 16 T1aEL post EVAR, and 15 short neck AAA). Configurations with one, two, three, and four fenestrations were used in 5, 56, 39, and 27 cases, respectively, for a total of 342 visceral vessels. One hundred and eight (85%) bifurcated and 19 (15%) tube endografts were implanted. In 35% (44/127) of cases the endograft was repositioned during the procedure, and 37% (128/342) of TVV were cannulated from brachial access. TS was 87% (111/127): five T1EL, six T3EL (between fenestration and vessel stent), and six loss of visceral vessels (one patient with a Type Ia EL had also a TVV loss) occurred. Thirty day mortality was 4% (5/127). Two of the five T1EL resolved spontaneously at 30 days. The overall median follow up was 21 ± 16 months; one T1EL (5%) occurred at six months and one T3EL (4%) at the three year follow up. Another two (3%) TVV occlusions occurred at six months and five (3%) at three years. The re-intervention rate at the 30 days, six months, and three year follow up was 5%, 7%, and 18 ± 5%, respectively. CONCLUSION: The fenestrated Anaconda™ endograft is effective in the treatment of complex AAA. Some structure properties, such as the re-positionability and the possibility of cannulation from above, are specific characteristics helpful for the treatment of some complex anatomies.

RESUMO

OBJECTIVES: Left subclavian artery (LSA) revascularization in thoracic endovascular aortic repair (TEVAR) remains controversial. Left subclavian artery coverage without revascularization can cause stroke and death. TEVAR has gained popularity for the treatment of chronic type B aortic dissection (cTBD). Using the Vascular Quality Initiative (VQI) database, we reviewed outcomes of LSA revascularization in TEVAR for cTBD. METHODS: The VQI registry identified 5683 patients treated with TEVAR from July 2010 to July 2016, including 208 repairs for cTBD. We analyzed outcomes per the Society for Vascular Surgery reporting standards. RESULTS: Of the 208 patients, 150 (72.1%) were male with a median age of 65.0 years (interquartile range [IQR], 55.0-72.0). Median aneurysm diameter was 5.7 cm (IQR, 5.0-6.5 cm). Data on the patency of the LSA was available in 131 (63.0%) patients. Twenty-five (19.1%) had occlusion of the LSA without revascularization, while 106 (80.9%) maintained patency or had revascularization. Successful device delivery occurred in all 131 (100%) patients. Maintaining LSA patency did not affect the rate of cerebrovascular accident (P = .16), spinal cord ischemia (P = 1.00), or death (P = 1.00). This was also nonsignificant when analyzing the subgroup of 98 elective cases. There was no difference in the rates of endoleak. Any intervention for the LSA (revascularization or occlusion) led to a longer procedure time (203.6 minutes vs 163.7 minutes, P = .04). CONCLUSIONS: Maintaining LSA patency during TEVAR for cTBD offers no advantage in perioperative morbidity or endoleak. Occlusion of LSA may be performed safely in this cohort and revascularization reserved for those who have anatomy that compromises perfusion to critical organs.

RESUMO

The nuance of operative decision making for those in need of emergent operation during coronavirus disease 2019 (COVID-19) pandemic is increasingly complex in the absence of robust data or guidelines. We present two cases of thoracic aortic emergencies with COVID-19 disease who survived high-risk operations to highlight the potential for successful outcomes even in situations compounding patient disease, morbid operation, and the added risk associated with virulent disease in the pandemic time.

RESUMO

PURPOSE: Our objective was to determine significant predictors of spinal cord ischemia (SCI) following Thoracic Endovascular Aortic Repair (TEVAR) and to further develop a simple and clinically orientated risk score model. METHODS: A retrospective review of data from the Society of Vascular Surgery/Vascular Quality Initiative national data set was performed for all patients undergoing TEVAR from January, 2014 to June 2018. Preoperative demographics, procedure-related variables, and clinical details related to SCI were examined. A SCI risk score was developed utilizing a multivariable logistic regression model. RESULTS: For the 7889 patients in the final analysis who underwent TEVAR during the study period, the mean age was 67.6 ± 13.9, range 18 to 90 years, and the majority was male (65%). Postoperative outcomes included stroke (3.0%), myocardial infarction (2.9%), inhospital mortality (5.4%), transient SCI (1.5%), and permanent SCI (2.1%). Nearly half of the overall cases were performed in high volume centers. Predictors of increased risk for SCI included age by decade (odds ratio [OR]: 1.2), celiac coverage (OR: 1.5), current smoker (OR: 1.6), dialysis (OR: 1.9), 3 or more aortic implanted devices (OR: 1.7), emergent or urgent surgery (OR: 1.5), adjunct aorta-related procedure (OR: 2.5), adjunct not related (OR: 2.6), total estimated length of aortic device (19-31 cm, OR: 1.9 and ≥32 cm, OR: 3.0), ASA class 4 or 5 (OR: 1.6), and procedure time ≥154 minutes (OR: 1.8). Two predictors decreased the risk of SCI, cases from high-volume centers (OR: 0.6) and eGFR ≥ 60 (OR: 0.6). To evaluate the risk score model, probabilities of SCI from the original regression, raw score, and raw score categories resulted in area under the curve statistics of 0.792, 0.786, and 0.738, respectively. CONCLUSIONS: Spinal cord ischemia remains one of the most feared complications of TEVAR. Incidence of SCI in this large series of patients with TEVAR was 3.6% with nearly 60% being permanent. The proposed model provides an assessment tool to guide clinical decisions, patient consent process, risk-assessment, and procedural strategy.

RESUMO

Purpose: To summarize the experience and outcomes of total endovascular repair of thoracoabdominal aortic disease using 3-dimensional (3D) printed models to guide on-site creation of fenestrations in aortic stent-grafts. Materials and Methods: From April 2018 to March 2019, 34 patients (mean age 58±14 years; 24 men) with thoracoabdominal aortic disease were treated in our department. Nineteen patients had thoracoabdominal aortic dissection and 15 had thoracoabdominal aortic aneurysm. Preoperatively, a 3D printed model of the aorta was made according to computed tomography images. In the operating room, the main aortic stent-graft was completely released in the 3D printed model, and the position of each fenestration or branch was marked on the stent-graft. The fenestrations were then made using an electric pen. Wires were sewn to the edge of the fenestrations using nonabsorbable sutures. After customization, the aortic stent-graft was reloaded into the delivery sheath and deployed. Results: The printing process took ~5 hours (1 hour for image reconstruction, 3 hours for printing, and 1 hour for postprocessing). The physician-modified stent-grafts had a total of 107 fenestrations secured by 102 bridging stent-grafts, including 73 covered stents and 29 bare stents. The average procedure time was 5.6±1.2 hours, including a mean 1.3 hours for stent-graft customization. No renal insufficiency or paraplegia occurred. Two branch arteries were lost during the operation. One patient (3%) died 1 week after surgery from a retrograde dissection rupture. One patient developed a minor cerebral infarction postoperatively. The mean follow-up time was 8.5 months. There was 1 endoleak from a fenestration (coil embolized) and 4 distal ruptures of the aortic dissection (3 treated and 1 observed). Conclusion: Three-dimensional printing can be used to guide creation of fenestrated stent-grafts for the treatment of thoracoabdominal aortic diseases involving crucial branches. This technique appears to be more accurate than the traditional measurement method, with short-term follow-up demonstrating the safety and reliability of the method. However, further research and development are needed.
