Robotic First Rib Resection in Thoracic Outlet Syndrome: A Systematic Review of Current Literature.

Thoracic outlet syndrome (TOS) involves the compression of neurovascular structures in the thoracic outlet. TOS subtypes, including neurogenic (nTOS), venous (vTOS), and arterial (aTOS) are characterized by distinct clinical presentations and diagnostic considerations. This review explores the incidence, diagnostic challenges, and management of TOS with a focus on the innovative approach of Robotic First Rib Resection (R-FRR). Traditional management of TOS includes conservative measures and surgical interventions, with various open surgical approaches carrying risks of complications. R-FRR, a minimally invasive technique, offers advantages such as improved exposure, reduced injury risk to neurovascular structures, and shorter hospital stays. A comprehensive literature review was conducted to assess the outcomes of R-FRR for TOS. Data from 12 selected studies involving 397 patients with nTOS, vTOS, and aTOS were reviewed. The results indicate that R-FRR is associated with favorable intraoperative outcomes including minimal blood loss and low conversion rates to traditional approaches. Postoperatively, patients experienced decreased pain, improved function, and low complication rates. These findings support R-FRR as a safe and effective option for medically refractory TOS.

Anterior Scalene Anomaly in a Patient With Arterial and Neurogenic Thoracic Outlet Syndrome.

Compression of the neurovascular structures of the upper extremity as they pass through the thoracic outlet result in thoracic outlet syndrome. The myriad of symptoms associated with the syndrome vary based on the structure(s) compressed: the subclavian artery/vein or the inferior trunk of the brachial plexus. This is a common site of compression especially in the presence of upper extremity injury, overuse or anatomical abnormalities. Majority of patients present with neurogenic pain and weakness; herein, we present the case of a patient with symptoms of both arterial and neurogenic compression caused by aberrant anterior scalene anatomy. These patients are excellent surgical candidates for first rib resection and anterior scalenectomy. A transaxillary approach offers the clinician an adequate window to identify anatomical abnormalities intraoperatively and safely excise the first rib and anterior scalene muscle.

Hydrodissection for the Treatment of Vascular Thoracic Outlet Syndrome.

The following case explores the effectiveness of a new treatment modality for vascular thoracic outlet syndrome (vTOS). Few conservative treatments exist to alleviate symptoms of vTOS. In this case, a 25-year-old male was diagnosed with vTOS four months prior to presentation. A combination of poor posture, inactivity, and protruding screws from a prior clavicle fracture repair were compromising the subclavicular vasculature. Symptoms of claudication and a cold right arm/hand led the patient to seek medical treatment. Post failed physiotherapy and pharmacotherapy, the vascular surgeon advised for surgery. He was hesitant to undergo major surgical intervention; therefore, after exploring possible remedies, hydrodissection was chosen for its potential merit in this case. After hydrodissection was performed to decompress the subclavicular neurovascular bundle, the patient reported immediate alleviation of his symptoms. Post two-week and three-month follow-up, there was complete resolution of symptoms with no recurrence. Although there is a lack of literature supporting the use of hydrodissection to treat vTOS, this was a specific case in which hydrodissection demonstrated to be an effective treatment modality. The specific utilization of hydrodissection should be further studied to increase the literature base and increase awareness of its potential effectiveness for this and similar conditions.

Endovascular reconstruction of bilateral upper limbs ischemia in a patient with arterial outlet syndrome: A case report and literature review.

Background: Acute upper limb ischemia in a patient with thoracic outlet syndrome is a rare but serious clinical disorder. If the disease is not treated promptly due to underdiagnosis, it could lead to distal artery embolization and limb-threatening ischemia. Revascularizing upper extremity arteries in a timely manner could rescue ischemic limbs and improve the patient's quality of life. We reported here a case of a patient who presented with bilateral upper limb ischemia caused by arterial thoracic outlet syndrome. Case presentation: A 63-year-old woman who presented with sudden bilateral upper extremity cold, numbness, pulselessness, and altered temperature sensation was first diagnosed with arterial thoracic outlet syndrome. The patient had performed a lot of pull-up and lat pull-down exercises in the 2 months prior to the onset of the above symptoms. Color Doppler ultrasonography showed thrombosis in the right axillary artery and left subclavian and axillary artery. The patient received Rotarex mechanical thrombectomy combined with drug-coated balloon percutaneous transluminal angioplasty (PTA) to complete revascularization of the upper extremities and achieved a full recovery finally. Conclusions: Complete endovascular revascularization for treating arterial thoracic outlet syndrome is a minimally invasive and effective method, especially for upper extremity ischemic lesions caused by nonbone compression.

Vascular thoracic outlet syndrome: Registry of 30-years of patient's outcomes at King Saud University Medical City, Riyadh, Saudi Arabia.

OBJECTIVES: To outline our experience with both arterial vascular thoracic outlet syndrome (ATOS) and venous TOS (VTOS). METHODS: This was a retrospective review carried out at King Saud University Medical City, Riyadh, Saudi Arabia, from 1992-2022. All patients were diagnosed based on clinical presentation, imaging, and underwent surgical decompression solely via the supraclavicular approach. The median follow-up period was 18 months (range: 4-36 months). RESULTS: A total of 90 limbs were diagnosed with vascular TOS in 69 patients. Females accounted for 69.6% of the patients and approximately 86.7% had ATOS. All patients were symptomatic and underwent plain thoracic inlet and cervical spine radiography, along with duplex scans in both rest and provocative positions. Total cervical rib resection was carried out in 60% of cases, while 2% had partial resection. First rib resection was carried out in 13.3% of cases and combined cervical and first rib resections were carried out in 23.3%. Vascular procedures were needed for arterial repair in 20% of cases, while venous repair were carried out in 2.2%. No recurrence or post-operative mortality had been reported. Post-operative complications were observed in 18.9% of cases. CONCLUSION: Careful patient selection and diagnosis using advanced, but less invasive radiological imaging coupled with adequate surgical treatment can improve the patient's outcome.

Thirty-year single-center experience with arterial thoracic outlet syndrome.

OBJECTIVE: Arterial thoracic outlet syndrome (ATOS) is rare. We present our 30-year experience with the management of ATOS at a high-volume referral center. METHODS: A retrospective review of all patients who had undergone primary operative treatment for ATOS from 1988 to 2018 was performed. ATOS was defined as subclavian artery pathology caused by extrinsic compression from a bony abnormality within the thoracic outlet. RESULTS: A total of 41 patients (45 limbs) underwent surgery for ATOS at a median age of 46 years (interquartile range [IQR], 34-58 years). Chronic symptoms (>6 weeks) were present in 31 limbs (69%). Of the 45 limbs, 13 (29%) presented with acute limb ischemia (ALI), requiring urgent brachial artery thromboembolectomy (BAT) in 9 and catheter-directed thrombolysis and thrombectomy (CDT) in 4. All patients underwent thoracic outlet decompression. 31 limbs (69%) required subclavian artery reconstruction. No perioperative deaths and only one major adverse limb event occurred. Patients with ALI underwent staged thoracic outlet decompression after initial BAT or CDT at a median of 23 days (IQR, 11-140 days). Of the 13 limbs with an initial presentation of ALI, 8 (62%) had recurrent thromboembolic events before thoracic outlet decompression subsequently requiring 10 additional BATs and 1 CDT. The cumulative probability of recurrent embolization at 14, 30, and 90 days was 8.33% (95% confidence interval [CI], 1.28%-54.42%), 16.67% (95% CI, 4.70%-59.06%), and 33.33% (95% CI, 14.98-74.20%), respectively. The median follow-up for 32 patients (35 limbs) was 13 months (IQR, 5-36 months). Subclavian artery/graft primary and secondary patency was 87% and 90%, respectively, at 5 years by Kaplan-Meier analysis. Of the 35 limbs, 5 (14%) had chronic upper extremity pain and 5 (14%) had persistent weakness. Preoperative forearm or hand pain and brachial artery occlusion were associated with chronic pain (P = .04 and P = .03) and weakness (P = .03 and P = .02). Of the 13 limbs that presented with ALI, 11 had a median follow-up after thoracic outlet decompression of 6 months (IQR, 5-14 months), including 9 (82%) with oral anticoagulation therapy. Anticoagulation therapy had no effect on subclavian artery patency (P = 1.0) or the presence of chronic symptoms (P = .93). CONCLUSIONS: The presentation of ATOS is diverse, and the diagnosis can be delayed. Preoperative upper extremity pain and brachial artery occlusion in the setting of ALI were associated with chronic pain and weakness after thoracic outlet decompression. Delayed thoracic outlet decompression was associated with an increased risk of recurrent thromboembolic events for patients who presented with ALI. An early and accurate diagnosis of ATOS is necessary to reduce morbidity and optimize outcomes.

Recurrent middle cerebral artery stroke caused by arterial thoracic outlet syndrome and coagulopathy.

Thoracic outlet syndrome (TOS) is defined as compression of neurovascular components passing the thoracic outlet. While neurologic compression is the most common form, rare cases of arterial comprssion could result in concerning cerebral thromboembolic events. Here we present a 15-year-old female with repeated left hemiparesis and radiologic signs of cerebrovascular accident (CVA) in right middle cerebral artery. Further investigations revealed stenosis of the right subclavian artery, saccular aneurysm, and occlusion of the right brachial artery which suggested the diagnosis of arterial TOS. Based on this report, we present this diagnosis as a rare but important cause of CVA, especially in young patients.

The evolving role of endovascular therapy in the management of arterial thoracic outlet syndrome.

OBJECTIVE: Over the past two decades, vascular surgeons have successfully incorporated endovascular techniques to the routine care of patients with arterial thoracic outlet syndrome (ATOS). However, no reports have documented the impact of endovascular therapy. This study describes the trends in management of ATOS by vascular surgeons and outcomes after both endovascular and open repair of the subclavian artery. METHODS: We queried a single-institution, prospectively maintained thoracic outlet syndrome database for ATOS cases managed by vascular surgeons. For comparison, cases were divided into two equal time periods, January 1986 to August 2003 (P-1) vs September 2003 to March 2021 (P-2), and by treatment modality, open vs endovascular. Clinical presentation, outcomes, and the involvement of vascular surgeons in endovascular therapy were compared between groups. RESULTS: Of 2200 thoracic outlet syndrome cases, 51 were ATOS (27 P-1, 24 P-2) and underwent 50 transaxillary decompressive operations. Forty-eight cases (92%) presented with ischemic symptoms. Thrombolysis was done in 15 (29%). During P-1, vascular surgeons performed none of the catheter-based interventions. During P-2, vascular surgeons performed 60% of the angiograms, 50% of thrombolysis, and 100% of stent grafting. Subclavian artery pathology included 16 aneurysms (31%), 15 stenoses (29%), and 19 occlusions (37%). Compared with open aneurysmal repair, endovascular stent graft repairs took less time (241 vs 330 minutes; P = .09), incurred lower estimated blood loss (103 vs 150 mL; P = .36), and had a shorter length of stay (2.4 vs 5.0 days; P = .10). Yet the endovascular group had decreased primary (63% vs 77%; P = .481), primary assisted (75% vs 85%; P = .590), and secondary patency rates (88% vs 92%; P = .719), at a mean follow-up time of 3.0 years for the endovascular group and 6.9 years for the open group (P = .324). These differences did not achieve statistical significance. Functionally, 84% of patients were able to resume work or school. A majority of patients (88%) had a good to excellent functional outcome based on their Derkash score. Somatic pain scores and QuickDASH (disabilities of the arm, shoulder, and hand) scores decreased postoperatively, 2.9 vs 0.8 (P = .015) and 42.6 vs 12.6 (P = .004), respectively. CONCLUSIONS: This study describes the evolving role of endovascular management of ATOS over the past two decades and documents the expanded role of vascular surgeons in the endovascular management of ATOS at a single institution. Compared with open repair, stent graft repair of the subclavian artery may be associated with shorter operative times, less blood loss, but decreased patency, without changes in long-term functional outcomes.

Functional outcome of arterial thoracic outlet syndrome treatment.

Introduction: The low prevalence of Arterial Thoracic Outlet Syndrome (ATOS) and diffuse symptomatology have resulted in limited data on optimal treatment strategies and long-term outcome. The aim of this study was to report and evaluate a single center experience with the treatment of ATOS including midterm patient reported outcome. Methods: All patients treated for ATOS from 2004 to 2020 were retrospectively identified. Patients were divided into two groups based on presenting symptoms; ATOX group (Acute arterial occlusion with ischemia) and ATOS group (claudication symptoms). Baseline characteristics and treatment details were extracted from electronic patient files. A telephone survey was conducted to collect patients' follow-up data including a functional disability score using the Quick Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. The primary endpoint of this study was symptom-free survival. Secondary endpoints were median QuickDASH scores during follow-up, postoperative complications and possible re-interventions. Results: A total of 20 patients (mean age 44.6 years, median follow-up 50.5 months) were included and divided into two groups (ATOX N = 9, ATOS N = 11). In the ATOX group, eight patients were primarily treated with catheter directed thrombolysis (CDT; N = 5) or surgical thrombectomy (N = 3). All patients received staged thoracic outlet decompression surgery (TOD). In the ATOS group, 10 patients primarily received TOD and one patient was treated conservatively with physiotherapy. Seven ATOX patients and nine ATOS patients were symptom free at follow-up with a median QuickDASH score of 2.3 (IQR 12.5) and 2.3 (IQR 16.5) respectively. Ten complications occurred in the ATOX group; three bleeding complications, five re-occlusions, one arterial dissection and one occipital infarction. In the ATOS group five complications occurred; one perioperative bleeding complication, three re-occlusions and a stent fracture. Seven vs. five re-interventions were required in the ATOX and ATOS groups respectively. Conclusion: The mid-term self-reported symptom free survival in both the ATOX as well as ATOS group seems acceptable while median QuickDASH scores in both groups indicate a very good functional outcome. This however comes at the cost of treatment related bleeding complications in especially the ATOX group presumably due to thrombolysis, and re-interventions required in almost one out of three patients.

Arterial thoracic outlet syndrome.

Thoracic outlet syndrome (TOS) is used to describe the constellation of symptoms arising from neurovascular compression of the thoracic outlet. The structures passing through the thoracic outlet include the subclavian artery, subclavian vein and trunks of the brachial plexus. Patients may experience symptoms related to compression of any one or various combinations of these structures. Arterial pathology as the cause of TOS is rare, though repetitive overhead arm motion, such as seen in athletes, is a risk factor for developing arterial TOS (aTOS). Symptoms include chronic findings, such as pallor, arm claudication or cool arm. Currently diagnosis of aTOS is made using clinical and imaging parameters which include focused history and physical including provocative maneuvers and imaging follow-up ranging from angiography to MRI. Occasionally, acute thrombosis can result in limb threatening ischemia requiring emergent catheter directed thrombolysis. Outside of acute limb ischemia, management of aTOS is variable, however typically begins with conservative measures such as physical therapy. In patients who do not respond or progress on conservative management, surgical decompression may be performed. Open or endovascular treatment of subclavian artery pathology may be necessary for recalcitrant cases. In this article, the aim is to review the elements involving diagnosis and management of aTOS.

Arterial Thoracic Outlet Syndrome in a Runner.

Thoracic outlet syndrome (TOS) most commonly manifests in overhead athletes (e.g., baseball pitchers, swimmers, weight lifters) due to nerve compression caused by skeletal abnormalities. We present the case of a 43-year-old recreational runner with unilateral upper extremity pain while running. Vascular imaging identified an aberrant subclavian artery origin with positional compression in the absence of cervical bone anomalies confirming arterial TOS. A first rib resection and anterior scalenectomy led to symptom resolution. This case emphasizes the importance of a broad differential and complete workup in non-overhead athletes presenting with symptoms consistent with neurogenic TOS, as vascular interventions may be necessary to prevent future complications.

Digital ischaemia of the upper limbs in middle age: consider arterial thoracic outlet syndrome until proven otherwise!

OBJECTIVES: Patients presenting with digital upper limb ischaemia are occasionally referred to rheumatology services to rule out vasculitis. We aimed to present two cases of delayed diagnosis of arterial thoracic outlet syndrome (aTOS) in middle-aged patients presenting with digital ischaemia in order to raise awareness of this important pathology that requires timely surgical intervention. METHODS: Two cases of progressive ischaemia of the right upper extremity caused by primarily undiagnosed compression of the subclavian artery by an accessory cervical rib are presented. The case notes, radiological images, intra-operative and postoperative findings for both patients were reviewed. Patients were followed up after ≥6 months to assess prognosis. RESULTS: Both patients had a working diagnosis of Buerger's disease and had been treated with prostaglandin infusions before establishment of the diagnosis of arterial thoracic outlet syndrome. Both patients were heavy smokers, and one patient had bilateral symptoms and a history of axial SpA and positive HLA-B27. Late presentation in one patient led to the loss of three fingers and the need for plastic reconstructive surgery after cervical rib resection and revascularization. In the other patient, surgical thrombectomy of the upper limb arteries along with resection of a cervical rib and repair of the subclavian artery with an interposition graft were necessitated to heal digital ulcers successfully. CONCLUSION: A high index of suspicion of aTOS should be maintained in middle-aged patients presenting with digital or upper limb ischaemia even in the presence bilateral symptoms or relevant risk factors of other diagnoses, such as smoking or a positive rheumatological history.

Evaluation and Management of Arterial Thoracic Outlet Syndrome.

Arterial thoracic outlet syndrome is rare and may be associated with a bony anomaly. Patient presentation can range from mild arm discoloration and claudication to severe limb-threatening ischemia. For patients with subclavian artery dilation without secondary complications, thoracic outlet decompression and arterial surveillance is sufficient. Patients with subclavian artery aneurysms or distal embolization require decompression with reconstruction or thromboembolectomy and distal bypass respectively.

Posterior cerebral artery stroke by reverse flow embolism in thoracic outlet syndrome - a case report.

BACKGROUND: Arterial thoracic outlet syndrome is a rare condition characterized by a subclavian artery pathology associated with a bone abnormality. It is rarely associated with thromboembolic stroke. The mechanism of cerebral embolism associated with thoracic outlet syndrome have rarely been demonstrated. We present here a fully studied case with a high probability of reverse flow embolism. CASE PRESENTATION: A 24-year-old man with a known arterial thoracic outlet syndrome presented with a right cerebral posterior artery brain infarction. An ultrasound examination depicted the compression of the right subclavian artery in the scalene defile with a post stenotic aneurysm and the presence of a floating thrombus in this aneurysm. There was a reverse flow during diastole in this aneurysm. Anticoagulation was carried out with the disappearance of the floating thrombus with no new clinical or brain MRI event. Corrective surgery of this thoracic outlet syndrome was performed one month after stroke. CONCLUSION: Very few cases of stroke in arterial thoracic outlet syndrome have been described with thorough dynamic vascular imaging. To our knowledge, this is the fourth reported case that advocates for a reverse flow embolism mechanism in stroke associated with thoracic outlet syndrome, and the first to realize an extensive ultrasound and doppler workup.

Overview of arterial pathology related to repetitive trauma in athletes.

BACKGROUND/OBJECTIVE: Sport-related vascular trauma is an important consequence of increased physical activity. Repetitive, high-intensity movements predispose athletes to vascular disease, including arterial pathology, by exerting increased pressure on neurovascular structures. This is an important source of morbidity in an otherwise young and healthy population. Arterial pathology associated with repetitive trauma is often misdiagnosed as musculoskeletal injury. This article increases awareness of sport-related arterial disease by reviewing the symptomatology, investigation, and treatment modalities of this pathology. In addition, prognostic outcomes specific to the athlete are discussed. RESULTS: Arterial thoracic outlet syndrome and vascular quadrilateral space syndrome are associated with athletes involved in overhead throwing exercises. Sport-related arterial pathology of the lower limb include external iliac artery endofibrosis (EIAE), popliteal artery entrapment syndrome (PAES), and adductor canal syndrome. Vascular stress and kinking secondary to vessel tethering are important contributors to pathology in EIAE. Chronic exertional compartment syndrome must also be considered, presenting with clinical features similar to PAES. In addition, athletes are predisposed to blunt mechanical trauma. Hypothenar hammer syndrome is one such example, contributing to a high burden of morbidity in this population. CONCLUSIONS: In arterial thoracic outlet syndrome and vascular quadrilateral space syndrome, surgery is advocated in symptomatic individuals, with postoperative outcomes favorable for the athlete. Acute limb ischemia may occur as a result of secondary thrombosis or embolization, often without preceding claudication. PAES and adductor canal syndrome are associated with functional entrapment in the athlete, secondary to muscular hypertrophy. Surgical exploration may be indicated. Poorer outcomes are noted when this process is associated with vascular reconstruction. Surgical treatment of EIAE follows failure of conservative management, with limited data available on postoperative prognosis. Investigations for all these conditions should be targeted based on clinical suspicion. A delay in diagnosis can have severe consequences on return to competition in these high-functioning individuals.

Ataque cerebrovascular recurrente secundario a síndrome del opérculo torácico arterial causado por sinostosis de la primera y la segunda costillas torácicas: reporte de caso / Recurrent Stroke Secondary to Arterial Thoracic Outlet Syndrome Caused by First and Second Ribs Synostosis: Case Report

El ataque cerebrovascular recurrente (ACV) es una complicación rara del síndrome del opérculo torácico arterial. Presentamos un paciente de 24 años con isquemia del miembro superior derecho y ACV recurrente en territorio vertebro basilar secundario a estenosis y aneurisma de la arteria subclavia, causado por sinostosis de la primera y segunda costillas torácicas. El paciente fue tratado quirúrgicamente con costocondrectomía y escalenectomía bilateral, resección de aneurisma de la arteria subclavia derecha y anastomosis primaria. Se analizó el caso y se revisó la literatura pertinente sobre ACV y síndrome de opérculo torácico arterial.

Stroke is a rare complication of arterial thoracic outlet syndrome. We present a 24-year old man with right arm ischemia and recurrent vertebrobasilar stroke caused by synostosis of the first and second thoracic ribs. The patien was treated with supraclavicular resection of both first ribs and bilateral scalenectomy, aneurysmal resection and primary anastomosis of the right subclavian artery. We analize this case and review the pertinent literature on stroke and arterial thoracic outlet syndrome.

Vascular Thoracic Outlet Syndrome.

Two distinct terms are used to describe vascular thoracic outlet syndrome (TOS) depending on which structure is predominantly affected: venous TOS (due to subclavian vein compression) and arterial TOS (due to subclavian artery compression). Although the venous and arterial subtypes of TOS affect only 3% and <1% of all TOS patients respectively, the diagnostic and management approaches to venous and arterial TOS have undergone considerable evolution due to the recent emergence of minimally invasive endovascular techniques such as catheter-directed arterial and venous thrombolysis, and balloon angioplasty. In this review, we discuss the anatomical factors, etiology, pathogenesis and clinical presentation of vascular TOS patients. In addition, we use the most up to date observational evidence available to provide a contemporary approach to the diagnosis and management of venous TOS and arterial TOS patients.

Nontraumatic Subclavian Artery Abnormalities: Spectrum of MDCT Findings.

OBJECTIVE: The subclavian arteries (SCAs) may exhibit a wide spectrum of nontraumatic pathologic conditions ranging from common diseases, such as atherosclerosis, to vascular emergencies that are associated with a high morbidity and high mortality, such as type A aortic dissection and acute arterial thrombosis. MDCT angiography is an excellent modality to diagnose pathologic conditions of the SCAs. CONCLUSION: Optimization of CT acquisition protocols and interactive interpretation with 2D multiplanar reformatting and 3D rendering techniques are critical for diagnostic accuracy.

Late recurrent peripheral upper limb ischemia after non-union of a clavicle fracture.

A 74-year-old woman was referred to our hospital due to recurrent episodes of upper limb ischemia. Her past medical history included a clavicle non-union developed after a clavicle midshaft fracture that had occurred 30 years previously. After a long asymptomatic period, she started showing symptoms of chronic ischemia to the left arm that were misdiagnosed. Thoracic outlet syndrome (TOS) is a rare but possible complication of mal-union and non-union of clavicle fractures; symptoms related to arterial involvement (ATOS) amount to less than 1% of all existing forms of thoracic outlet syndrome. In case of clavicle non-union, local instability plays a key role in determining the initial injury to the vessels and the recurrence of symptoms. Restoration of local bone stability and anatomy, obtained by compression plating and autologous bone grafting, combined with an appropriate vascular surgery, is essential to achieve a clinical resolution of symptoms and to avoid the recurrence of symptomatology as seen in the herein case.

Non-union of a clavicle fracture: lateral fragment excision for brachial artery embolism.

A 67-year-old motorcyslist was admitted to hospital following a high-speed road traffic collision and found to have a left midshaft clavicle fracture and multiple ipsilateral rib fractures. He was treated conservatively and went on to have non-union of the clavicle. The non-union was managed non-operatively. The patient then re-attended the hospital with an acute ischaemic left hand 3 years after the original injury date. An arterial duplex scan confirmed a embolus to the brachial artery. A brachial embolectomy was urgently performed. A computed tomography scan showed non-union of the clavicle fracture and an inflammatory mass compressing the left subclavian artery, which was the focus of the embolic event. The clavicle non-union was managed operatively with lateral half claviculectomy. Immediately after clavicle excision, the vascular team performed reconstruction of the brachial artery. At follow-up,there was normal shoulder and hand function at outpatient clinic. A duplex scan confirmed good triphasic waveforms throughout the arteries of the left upper limb.
