Effects of percutaneous endovascular angioplasty for severe stenosis or occlusion of subclavian artery

To investigate the effect and safety of percutaneous endovascular angioplasty (PEA) with optional stenting for the treatment of severe stenosis or occlusion of subclavian artery, patients with severe stenosis ≥ 70% or occlusion of subclavian artery treated with PEA were retrospectively enrolled. The clinical data were analyzed. A total of 222 patients were retrospectively enrolled, including 151 males (68.0%) and 71 females (32.0%) aged 48–86 (mean 63.9 ± 9.0) years. Forty-seven (21.2%) patients had comorbidities. Subclavian artery stenosis ≥ 70% was present in 201 (90.5%) patients and complete subclavian occlusion in 21 (9.5%) cases. Angioplasty was successfully performed in all (100%) patients. Balloon-expandable stents were used in 190 (85.6%) cases, and self-expandable stents in 20 (9.0%) cases. Only 12 (5.4%) cases were treated with balloon dilation only. Among 210 patients treated with stent angioplasty, 71 (33.8% or 71/210) cases underwent balloon pre-dilation, 139 (66.2% or 139/210) had direct deployment of balloon-expandable stents, and 2 (1.0% or 2/210) experienced balloon post-dilation. Distal embolization protection devices were used in 5 (2.3% or 5/222) cases. Periprocedural complications occurred in 3 (1.4%) patients, including aortic dissection in 2 (0.9%) cases and right middle cerebral artery embolism in 1 (0.5%). No hemorrhage occurred. Among 182 (82.0%) patients with 6-month follow-up, restenosis > 70% occurred in 1 (0.5%) patient, and among 68 (30.6%) patients with 12-month follow-up, restenosis > 70% took place in 11 (16.2%) patients. Percutaneous endovascular angioplasty can be safely and efficiently performed for the treatment of severe stenosis ≥ 70% or occlusion of subclavian artery.

Relationship Between Subclavian Artery Stenosis Lesions and Posterior Circulation Infarction: A Preliminary Study

To investigate the correlation between subclavian steal syndrome and posterior circulation infarction using magnetic resonance imaging. A total of 294 patients diagnosed with subclavian steal syndrome using carotid Doppler ultrasonography were retrospectively included. According to the magnetic resonance imaging results, they were divided into posterior circulation infarction group and nonposterior circulation infarction group. Clinical indicators and carotid Doppler ultrasound parameters of patients were collected, and they were screened to establish a multiple logistic regression model. Receiver operating characteristic curve analysis of the established multiple logistic regression model was performed, and the area under the curve was calculated to evaluate the predictive efficiency of the model. After statistical analysis of all parameters of the 2 groups of patients, a total of 10 parameters were included in multiple logistic regression to establish a model. The results showed a correlation between posterior circulation infarction and subclavian artery occlusion, grade III subclavian steal syndrome, gender, vulnerable plaques, National Institutes of Health Stroke Scale score, and age. After the receiver operating characteristic curve analysis of the model, the area under the curve for the multiple logistic regression model was 0.773. The multiparameter composite model based on clinical baseline data and carotid Doppler ultrasonography parameters can effectively predict posterior circulation infarction and offer novel insight for clinical diagnosis.

ACUTE CORONARY SYNDROME IN A PATIENT WITH LEFT SUBCLAVIAN OCCLUSION AND ANTEROLATERAL CORONARY STEAL

Abstract This is a 57–year–old male patient suffering from multiple cardiovascular risk factors: obesity, arterial hypertension, dyslipidemia, type 2 diabetes mellitus, active smoker. Chronic obstructive pulmonary disease. Stage 2 chronic kidney disease. Peripheral vascular disease with previous bilateral thromboendarterectomy and percutaneous revascularization of the lower limbs. Stable angina for which three years ago he underwent Coronary Artery Bypass Graft: left internal mammary artery (LIMA) to left anterior descending artery combined with saphenous vein grafts to the main obtuse marginal branch. The patient presented with Acute Coronary Syndrome non ST–segment elevation myocardial infarction (N–STEMI), intermittent episodes of chest pain due to mild exertion in the previous days. Antero–lateral ST depression and inverted T waves, associated with a mild reduction in left ventricular systolic function due to hypokinesia of the antero–lateral walls and increased troponin values were present. Coronary angiography documented patency of the LIMA graft without evidence of any culprit lesions on the coronary branches. However, selective angiography documented a sub–occlusion of the proximal left subclavian artery (Figure 1). A computed tomography scan confirmed a hyperdense calcified plaque occluding 95% of the origin of the left subclavian artery. The patient then underwent angioplasty with stenting of the left subclavian artery (Figure 2). Subclavian coronary steal syndrome usually presents with exertional angina, but rarely can cause Acute Coronary Syndrome. During coronary angiography performed for Acute Coronary Syndrome and in the absence of detection of clear coronary culprit lesions, selective angiography of the subclavian artery may confirm the suspicion of coronary steal syndrome.

Clinical study of 57 cases of endovascular treatment for total subclavian artery occlusion.

To investigate the safety and efficacy of endovascular treatment for totally occlusive lesions of the subclavian artery (SCA). A retrospective study was performed on 57 patients treated with angioplasty and stenting, including 42 males and 15 females, with an average age of 61.8years (range: 49 to 81years). Efficacy, safety, and complications were evaluated. Procedural success was achieved for 47/57 patients and symptoms were relieved. Rat-tail occlusion is the most common type, and all cases were successfully recanalized. Plain type occlusion is less common with a recanalization rate of 55.6%. Hilly and plain occlusions are the main types of stent implantation failure. Through univariate analysis and trend matching analysis, the type of SCA occlusion and surgical approach had statistical significance on the success rate of surgery. The mean follow-up time was 34.6 ± 16.2months. The cumulative stent patency rates at 1, 3, and 5years were 95.5%, 86.4%, and 77.3% in the calcified plaque group and 92.0%, 76.0%, and 68.0% in the non-calcified plaque group, respectively. The 3-year and 5-year patency rates in the calcified plaque group were higher than those in the non-calcified plaque group (p < .05). Different occlusion types and surgical approaches can affect the surgical success rate. The combined femoral and brachial approach can improve the rate of recanalization of SCA occlusions. The patency rates at 3 and 5years in the calcified plaque group were higher than those in the non-calcified plaque group.

Carotid-subclavian bypass in the treatment of subclavian artery occlusion during epidermoid cyst excision: A case report

In surgical cases, various complications may occur depending on the degree of difficulty and experience. In this case report, we present a 24-year-old patient who was operated 5 years ago for an epidermoid cyst in the right neck region and developed loss of strength in the right arm. Angiography revealed total occlusion of the right subclavian artery and right carotid-subclavian bypass was performed. It was aimed to emphasize the necessity of a multidisciplinary approach for the successful surgery of the case and the solution of developing complications.

Treatment for Stanford type B aortic dissection with insufficient anchoring region using castor integrated branched aortic stent graft.

To investigate the clinical efficacy of Castor integrated branched aortic stent graft for the treatment of Stanford type B aortic dissection with insufficient anchoring area. Retrospective analysis of clinical data of 26 patients with Stanford type B aortic dissection with insufficient anchoring region (<15 mm) treated by Castor branched aortic stent graft from September 2018 to June 2022 at Ganzhou People's Hospital, including 23 acute cases and 3 chronic cases. Surgical procedures were successfully performed in all 26 patients, and during the perioperative period no complications occurred, such as cerebrovascular accident, stenosis or occlusion of left subclavian artery, progression of reverse avulsion of aortic dissection, and paraplegia. During the operation 2 patients had a small amount of type I endoleak, which disappeared during the postoperative follow-up. The other patients had good postoperative follow-up results. Review of the aortic CTA indicated good stent morphology with patency of the left subclavian artery. The Castor integrated branched aortic stent graft expanded the indications for endoluminal treatment for Stanford type B aortic dissection, which can avoid open surgery and has good clinical outcomes.

Rare Association of Takayasu Arteritis and Antiphospholipid Syndrome with Severe Thrombocytopenia

The association of Takayasu arteritis (TA) with antiphospholipid syndrome (APS) has rarely been described in the literature. This paper reports the first documented case of TA and APS in a 24-year-old woman in Bangladesh. This patient had claudication pain in upper and lower limbs for four years and Raynaud’s phenomenon in right hand for eight months. During the course of her illness, she suddenly developed deep vein thrombosis in left superficial femoral, popliteal and posterior tibial veins. Conventional angiography revealed total occlusion of right subclavian artery and 60-70% stenosis of right common iliac artery. CT angiography of right upper limb also supported these findings along with increased wall thickening in the 2nd part of right subclavian artery and moderate narrowing of the 1st part of right axillary artery. She had persistently positive anticardiolipin antibodies in high titers, positive lupus anticoagulant (LA), prolonged activated partial thromboplastin time (APTT) and severe thrombocytopenia. We started high dose prednisolone (1mg/kg daily). Her platelet count increased rapidly. Based on review of 10 case reports, we considered the rare association of TA and APS. Both conditions should be determined promptly for the sake of early institution of the appropriate therapy. Bangabandhu Sheikh Mujib Med. Coll. J. 2023;2(1): 59-63

Screening for Subclavian Artery Stenosis

Introduction: Subclavian artery stenosis of &gt;50% has been linked to an increased risk of cardiovascular morbidity, complications after carotid interventions, and difficulty in managing hypertension. This has led to increased emphasis on screening for these lesions. In addition, these lesions may be associated with upper extremity symptoms including claudication and pain at rest. Methods: A retrospective review of patients who were referred over a 2-year period for arm pain in the setting of suspected or proven subclavian artery stenosis or occlusion was performed. This was compared to an unmatched cohort of patients who underwent carotid artery duplex with subclavian artery duplex for other reasons. Data included measuring the interbrachial systolic pressure difference (&gt;15 and &gt;20 mm Hg), arm-arm index, and hand acceleration time (HAT). Results: Among the172 patients studied, 48 had subclavian artery stenosis or occlusion and 26 of these had corresponding symptoms. Female gender ( P = .012), history of coronary intervention ( P = .007), hypertension ( P = .039), and arm-arm index of &lt;0.9 ( P = .0001) were significantly associated with subclavian artery stenosis or occlusion. A HAT of &gt;100 milliseconds was significantly associated with symptomatic subclavian artery stenosis or occlusion. Conclusions: An arm-arm index of &lt;0.9 is a useful tool for screening for subclavian artery stenosis. In patients with subclavian artery stenosis, HAT may be useful in confirming that the arm symptoms are due to this particular lesion.

Endovascular Treatment of Subclavian Artery Occlusion by Surgical Exposure of the Proximal Brachial Artery at the Side of an Arteriovenous Fistula.

A 76-year-old man undergoing hemodialysis complained of pain and discoloration of his right finger. The hemodialysis arteriovenous fistula was in the right upper extremity. Ultrasonography showed right subclavian artery occlusion. The lesion could not be approached from the lower extremity and olecranon artery. Thus, we performed the procedure after exposing the proximal brachial artery. We were able to recanalize the subclavian artery and restore blood flow to the right upper extremity. When the lesion is on the side of the arteriovenous fistula and approaching from the lower extremity is difficult, exposure of the proximal brachial artery can be considered.

Endovascular Treatment for Subclavian Artery Stenosis and Occlusion: A Single-Center Retrospective Study.

Subclavian artery stenosis and occlusion are common arterial diseases in the upper extremities, with atherosclerosis being the main cause. Endovascular treatment has emerged as a promising alternative to open surgical repair, but data are limited. This study aimed to evaluate the safety and effectiveness of endovascular procedures in the treatment of subclavian artery lesions at a tertiary vascular center in Vietnam. A retrospective analysis was conducted on patients who underwent endovascular treatment for symptomatic subclavian artery stenosis or occlusion between October 2013 and April 2022. Clinical characteristics, procedural details, short- and long-term outcomes, and patency rates were assessed. Twenty-five patients were included in the study, with a mean age of 56.8 years. The majority of patients had risk factors for atherosclerosis, and all presented with symptoms related to subclavian artery disease. The endovascular procedures were successful in 96% of cases, with a low complication rate of 8%. During a median follow-up of 43 months, the overall patency rate was 92% at three years. Endovascular treatment of subclavian artery stenosis and occlusion is a safe and effective option, with excellent long-term patency rates. These findings support the use of percutaneous revascularization as the first-line therapy, particularly in experienced centers. Further studies with larger sample sizes and longer follow-up periods are needed to confirm these results.

Clinic furniture arrangements leading to patient self-reported blood pressure discrepancy: a rare case of total occlusion of left subclavian artery

Subclavian artery occlusion is an uncommon condition affecting approximately 2% of the general population. Only 8.7% of patients with total occlusion of subclavian artery are asymptomatic. It has the potential to cause significant morbidity as it could contribute to the ischemic complications affecting the upper extremities, brain, and heart. We present a case of asymptomatic total occlusion of left subclavian artery which was found following investigations for discrepancy in blood pressure readings from the patient’s right and left arm. The difference was noted due to the clinic’s furniture arrangement. The patient was treated with stent insertion via percutaneous transluminal angioplasty. After three years of follow ups, she remains asymptomatic and free of cardiovascular-related complications.

Bahcet's Syndrome Resembling Takayasu's Arteritis with the Distribution of Arterial Involvement: A Case Report and Literature Review.

Behcet's syndrome is a variable vessel vasculitis characterized by recurrent oral and genital ulcers with concomitant skin, ocular, neurologic, gastrointestinal, and joint involvement. Herein, we present a patient who was diagnosed with Behcet's syndrome, which with magnetic resonance angiography showed occlusion of the right subclavian artery at the level of the thoracic outlet and reverse flow in the right vertebral artery consistent with subclavian steal syndrome. In addition, partial narrowing was noted in the left renal artery. The distribution of arterial involvement resembled Takayasu's arteritis, although the presence of mucocutaneous lesions, male gender, history of deep vein thrombosis, and HLA-B51 positivity favored a diagnosis of vasculo-Behçet's syndrome. We treated the patient with methylprednisolone and cyclophosphamide. After the regression of vascular inflammation with immunosuppressive therapy, stenting was performed in the left renal artery.

Subclavian Artery-Carotid Artery Bypass for Subclavian Artery or Common Carotid Artery Severe Stenosis or Occlusion.

Various surgical treatments are available for occlusive subclavian and common carotid artery diseases. Nevertheless, to date, when cerebral endovascular treatment is utilized, revascularization via direct surgery may be required. This study reported five symptomatic cases of revascularization for CCA and SCA occlusive and stenotic lesions that were expected to be challenging to treat with endovascular treatment. We performed subclavian artery-common carotid artery or internal carotid artery bypass using artificial blood vessels or saphenous vein grafts in five patients with subclavian steal syndrome, symptomatic common carotid artery occlusion, and severe proximal common carotid artery stenosis. In this study, good bypass patency was achieved in all five cases. Although there were no intraoperative complications, one patient had a postoperative lymphatic leak. Moreover, there was no recurrence of stroke during postoperative follow-up for an average of 2 years. Conclusively, subclavian artery-common carotid artery bypass can be an effective surgical treatment for common carotid artery occlusion, proximal common carotid artery stenosis, and subclavian artery occlusion.

Feasibility of Intravascular Lithotripsy for the Treatment of Calcified Supra-Aortic Vessels: A Case Report and Literature Review.

To report a case of coronary-subclavian steal syndrome (CSSS) due to a history of a left internal mammary artery (LIMA) to left anterior descending (LAD) artery coronary bypass (CABG) and a heavily calcified ostial left subclavian artery (LSA) occlusion, that was treated with intravascular lithotripsy (IVL) technique and to summarize the current trends of IVL treatment for supra-aortic vessels. A 64-year-old woman with progressive intermittent angina pectoris and a history of LIMA to LAD bypass underwent coronary angiography which demonstrated complete ostial occlusion of the LSA. Via brachial access, the patient underwent Shockwave IVL balloon treatment of the LSA and stent-graft implantation. At 9 months follow-up, the patient showed symptoms resolution, and duplex ultrasound (DUS) demonstrated a patent LSA. The Shockwave IVL system was demonstrated to be a feasible treatment and justified for selective cases of highly calcified lesions in supra-aortic vessels. The present case report and the literature review, in a total of 47 patients resulted in a high technical procedural success rate, with a low rate of complications. Future studies with larger cohorts are warranted to confirm these findings and standardize this technology in this particular vascular field. The present study exemplifies a case of recanalization of the left subclavian artery in a patient with coronary-subclavian steal syndrome with a heavily calcified ostial lesion treated with intravascular lithotripsy (IVL). In this paper, for the first time, a review of the contemporary literature on the use of IVL in supra-aortic vessels is reported, elucidating the feasibility of this technique in this vascular territory. Despite the heterogeneous features of the reported cases and the lack of a standardized protocol for the use of IVL in the management of highly calcified lesions of supra-aortic vessels, it was demonstrated to be a feasible technique, with a high technical success rate, being an advantageous tool for heavily calcified supra-aortic lesions.

TCTAP C-151 Rebuilding After the Fall: A Case With Traumatic Subclavian Artery Occlusion

TCTAP C-151 Rebuilding After the Fall: A Case With Traumatic Subclavian Artery Occlusion

Abstract Number ‐ 227: Retrograde embolism from a Subclavian Thrombus causing Acute Ischemic Stroke in the Middle Cerebral Artery

Introduction Intracranial embolism to the middle cerebral artery usually occurs because of embolization from the heart, carotid artery or the aorta. Here we describe a case of a subclavian thrombus, embolizing to the middle cerebral artery. Retrograde embolism is a rarely described mechanism of acute ischemic stroke. Methods A 49‐year‐old gentleman with a history of hyperlipidemia, peripheral artery disease, smoking, prior stroke, previously treated arteriovenous malformation (AVM) in the left parieto‐occipital region and active methamphetamine use presented with sudden onset dysarthria and left facial weakness (NIH stroke scale–3). CT angiogram (CTA) head and neck demonstrated a right M2 inferior division occlusion and noted nonocclusive thrombus attached to right subclavian artery atherosclerotic plaque, proximal to the origin of the right vertebral artery and otherwise minimal extracranial, and intracranial atherosclerotic disease. He was not a candidate for IV thrombolysis due to his AVM, or mechanical thrombectomy (MT) due to low NIHSS. Apixaban was started. Trans‐esophageal echocardiogram (TEE) demonstrated a grade 2 PFO. Venous doppler ultrasound performed of his upper and lower extremities was negative. On day 2 of hospitalization, his left hemiparesis and dysarthria worsened. Repeat CTA head and neck showed absence of the right subclavian thrombus and new distal M1‐MCA thrombus, suggestive of retrograde embolism from the right subclavian artery. The patient was started on IV heparin and aspirin. A stroke in young work‐up was sent including antinuclear antibodies (ANA), antineutrophil cytoplasmic antibodies (ANCA), homocysteine, hexagonal phase phospho proteins, antiphospholipid antibodies, HIV, rheumatoid factor, cryoglobulin, hepatitis B antibodies, hepatitis C antibodies, sickle cell screen, Sjogren’s syndrome antibodies, drug screen, and was negative. Results Embolism (cardioembolism and artery–artery embolism) to the intracranial vasculature is an important cause of acute ischemic stroke. Retrograde embolization is rarely described as a cause of ischemic stroke. Our patient presented initially with distal right M2 occlusion and subocclusive thrombus of the right subclavian artery, associated with focal atherosclerosis but otherwise patent extracranial and intracranial cerebral vessels. Work‐up including transesophageal echocardiogram, and hypercoagulable work‐up was unrevealing. Repeat CT angiogram obtained in view of worsening deficits revealed absence of his right subclavian thrombus and new distal M1‐MCA occlusion presumed retrograde embolism from the right subclavian artery. This is may represent the consequence of local turbulence and retrograde flow during diastole. Conclusions When considering sources of embolic stroke, retrograde embolism should be considered in patients with focal atherosclerosis.

Mid-Term Results of Treating Kommerell's Diverticulum and Aberrant Subclavian Artery Anomalies Using a Patient-Centered Team Approach.

The management of Kommerell's Diverticulum (KD) has evolved from open surgical resection and graft replacement of the aorta, to endovascular repair in asymptomatic patients due to its recognized possible sequelae - aortic rupture and dissection. Despite these technical advances, standard indications for intervention and treatment algorithms remain unclear. We will present our single-center experience in the treatment of KD, supporting a multidisciplinary endovascular-first approach. All patients who underwent thoracic endovascular aortic repair (TEVAR) for KD between 2017 and 2020 were retrospectively identified from a prospectively maintained institutional surgery database. Chart review was used to characterize presenting symptoms, interventions, technical results, and complications. Revascularization was performed using carotid-axillary bypass. Routine endovascular subclavian artery occlusion was employed to eliminate retrograde diverticulum perfusion and avoid open ligation. 8 patients were identified, including 6 females and 2 males between the ages of 44-76. Patients presented with dysphagia (n = 3), acute embolic stroke (n = 1), transient ischemic attack (TIA) (n = 1), upper extremity embolization (n = 1), and acute type B aortic dissection (n = 1). One patient had a prior incomplete open repair that was successfully treated endovascularly. Another patient had a mediastinal neoplasm infiltrating an incidental aberrant subclavian artery and KD. All cases had symptomatic improvement and successful endovascular repair as demonstrated on post-operative imaging. Perioperative complications included percutaneous access site pseudoaneurysm (n = 2), stroke (n = 1), and subclavian artery rupture immediately recognized and treated (n = 1). There was no perioperative mortality. Endovascular techniques have resulted in technical success and symptomatic improvement for KD without open thoracotomy or sternotomy. Significant rates of endovascular complications and paucity of long-term durability data should be considered. Until formal criteria for repair are established, early application of TEVAR using a consistent multi-specialty approach may mitigate the risk of unpredictable aortic complications in these patients while avoiding the accepted morbidity and mortality of open surgery.

Bilateral subclavian artery occlusion masking severe systemic hypertension as cause for heart failure: the role of multi-modality cardiovascular imaging in guiding diagnosis and management.

A 62-year-old female smoker presented with gradually worsening exertional breathlessness over 1 year, despite initiation of treatment for chronic obstructive pulmonary disease. She gave a history of transient ischaemic attack and possible subclavian artery stenosis diagnosed at a different institution. Physical examination revealed blood pressure (BP) readings of 80/50 mmHg in both arms. Electrocardiogram showed sinus rhythm with left bundle branch block (QRS duration 147 ms, Panel A). Echocardiography identified severe left ventricular (LV) systolic dysfunction (ejection fraction 29%) and suspected apical thrombus (Panel B, Supplementary data online, Video S1). She was initiated on ivabradine and considered for cardiac resynchronization therapy due to hypotension which limited the introduction of additional heart failure (HF) pharmacotherapy. Cardiovascular magnetic resonance confirmed LV dysfunction (supplementary data online, Video S2) and mild LV hypertrophy. There was septal fibrosis but no myocardial infarction or LV thrombus (Panel C & D), suggestive of non-ischaemic dilated cardiomyopathy phenotype. Computed tomography coronary angiography showed unobstructed coronary arteries but revealed bilateral subclavian artery occlusion (Panels E–G).

Subtypes of the Completely Reversed Flow Waveform in Vertebral Artery Can Help to Differentiate Subclavian Artery Occlusion from Severe Stenosis

To investigate the value of subtypes of completely reversed flow (CRF) waveform in vertebral artery (VA) on Doppler ultrasound in differentiation occlusion from severe stenosis of the ipsilateral proximal subclavian artery (SA). A total of 357 patients with CRF in the VA on Doppler US were reviewed retrospectively. Among them, 49 patients (mean age, 68.2 ± 7.8 years) confirmed by digital subtraction angiography (DSA) were included. According to the status of diastolic flow, the CRF was divided into continuous CRF (CCRF, n = 27) and intermittent CRF (ICRF, n = 22). The correlation of subtypes of CRF waveform and VA parameters with the severity of SA stenosis was evaluated. The severity of SA stenosis was determined by DSA. Of those 49 patients, SA occlusion was observed in 33 patients (67%, occlusion group) and severe stenosis in 16 patients (33%, stenosis group). The subtypes of CRF waveforms showed a significant between-group difference (p = 0.005). CCRF exhibited an accuracy of 85.2% (23/27) in diagnosing SA occlusion. The diameter of the target VA with ICRF showed a significant between-group difference (p = 0.041). The target VA diameter ≥ 3.8 mm in ICRF achieved an accuracy of 81.8% (18/22), and its combination with CCRF achieved an accuracy of 83.7% (41/49) in the differentiation of SA occlusion from severe stenosis. Subtypes of CRF in VA can help to differentiate SA occlusion from severe stenosis. CCRF has higher accuracy in diagnosing SA occlusion. The CCRF waveform plus VA diameter in ICRF is more accurate for differentiating SA occlusion from severe stenosis.

Implantation of a fenestriated stent-graft in a patient with thoracic aortic aneurysm

The authors present endovascular treatment of a patient with stenosis of the left anterior descending artery, chronic DeBakey type III aortic dissection and thoracic aortic aneurysm. The first stage was percutaneous coronary intervention with stenting of the left anterior descending artery. The second stage implied implantation of a fenestrated stent-graft. The follow-up CT angiography after 6 months revealed occlusion of the left subclavian artery that required stenting. Control CT angiography confirmed adequate stent-graft placement without endoleaks and stenosis of the artery. The choice of these reconstructions and stages of interventions are substantiated. The authors concluded effectiveness of treatment strategy, as well as the need for preventive subclavian artery stenting after implantation of a fenestrated graft.
