Chronic Pseudoaneurysm of the Right Subclavian Artery: A Rare Case Presentation and Review

Subclavian artery pseudoaneurysm after penetrating chest trauma: A case report

Introduction: Subclavian artery pseudoaneurysm is a rare entity with significant mortality and morbidity. Most injuries were related to iatrogenic manipulations, but in some cases, this injury has been described as secondary to a chest trauma. This case report presents a case of a subclavian artery pseudoaneurysm caused by a chest stabbing trauma. Case description: This case is the report of a twenty-four-year-old man with a chief complaint of a painful and pulsating mass on the right shoulder 3 months before admission at the scar on his chest after having penetrating chest trauma; he also complained about weakness on the right arm. An evaluation with thorax MSCT and CT angiography supports the diagnosis of the right subclavian artery pseudoaneurysm. Intraoperative, we found a fistula from the right subclavian artery with hematomas. From the post-operative evaluation, the patient showed motoric improvement in the right arm and no pain. The patient was discharged from the hospital on the ninth day after surgery. Conclusion: Prompt and accurate diagnosis is crucial in subclavian artery pseudoaneurysm for determining the appropriate therapeutic approach, both in surgical preparation and intraoperative focus.

Type I Endoleak Following Covered Stent Graft Placement for Traumatic Subclavian Artery Pseudoaneurysm

AbstractSubclavian artery pseudoaneurysm is an uncommon entity caused by trauma or iatrogenic arterial injury. Endovascular management is the preferred treatment strategy but can be complicated by endoleaks. We report a case of type I endoleak occurring after endovascular covered stent placement to treat a traumatic pseudoaneurysm of proximal left subclavian artery.

Endovascular treatment of large posttraumatic false aneurysm of the S2 segment of the subclavian artery: clinical case and literature review

Introduction. Pseudoaneurysms of the subclavian artery are a rare pathology and most frequently occur due to trauma. According to the current literature, subclavian artery aneurysms account for 1 % of all peripheral artery aneurysms. This pathology, although rare, may be accompanied by the risk of rupture, thrombosis, or distal embolism of the arterial lumen. Objective. To demonstrate a clinical case of a patient with successful treatment of subclavian artery pseudoaneurysm by means of modern minimally invasive endovascular technique. Material and methods. The article presents our clinical case with the use of endovascular technique for the treatment of large posttraumatic pseudoaneurysm of the S2 segment of the left subclavian artery using the Bard LifeStream balloon stent graft.Discussion. Currently, direct surgery is considered to be the gold standard of treatment in extracranial aneurysms. Meanwhile, availability of minimally invasive methods allows minimizing the risk by performing endovascular treatment and thus reducing the risk of foreign bodies and infectious complications associated with a large volume of surgical intervention in direct surgery, reducing damage to the brachial plexus, decreasing the number of beddays, and contributing to early rehabilitation measures. The strategy of choice in favor of endovascular treatment should be individual for each patient taking into account such factors as localization, aneurysm size, compression of nearby cranial nerves, and concomitant pathology with high risk of open surgical treatment. Conclusions. Careful selection of patients for endovascular technique will ensure good long-term outcome using all advantages of this technique. At present, it is still relevant and crucial to minimize complications and iatrogenic postoperative lesions in patients with this disease. For this reason, endovascular surgeries should be performed at the stage of specialized medical care by an experienced surgeon.Key words: subclavian artery, false aneurysm, posttraumatic aneurysm, stent graft, endovascular treatment, open surgery, minimally invasive surgery.

Endovascular treatment of the subclavian artery pseudoaneurysm

Endovascular treatment is widely used for treating the subclavian artery pseudoaneurysm (SAP) because of its small trauma, fast recovery, exact effect, and low incidence of complications. However, when the systemic disease or infection that causes SAP is in the active phase, treatment of the primary disease is more critical. Surgical intervention should be performed after systemic symptoms have been controlled unless the situation is particularly critical. We introduced two cases of SAP caused by brucellosis and Behcet's disease and discussed the course of treatment.

Excision of delayed presented giant pseudoaneurysm of left subclavian artery post stab injury

Post-traumatic pseudoaneurysms involving the subclavian artery are uncommon and whenever diagnosed they should be repaired early because of the risk of complications such as thrombosis, gangrene, limb disability, and rupture may result in death if not reached the hospital early. Presenting a case report of a 20-year-old male who presented with a left subclavian artery pseudoaneurysm following a stab injury to the left axilla. He was referred to our institute, 20 days after the alleged assault. The presentation, diagnosis, and management of this injury are discussed.

Open surgical treatment of subclavian artery pseudoaneurysm after endovascular repair: a case report

BackgroundSubclavian artery aneurysms are rare but may cause life-threatening complications. Surgical repair has been performed as a treatment of choice, but recently, with the development of endovascular treatment, many endovascular repairs have been performed to prevent surgical complications.Case presentationA patient undergoing endovascular repair with a subclavian artery aneurysm was diagnosed with a type II endoleak with an enlarged aneurysmal sac. Surgical repair was performed to remove the aneurysmal sac compressing the adjacent organs.ConclusionsThe highly mobile subclavian artery has abundant collaterals. Therefore, regular follow-up is essential for endovascular repair. Surgical repair is effective when adjacent organs are compressed by the aneurysm sac.

Brachial plexopathy due to subclavian artery pseudoaneurysm secondary to comminuted clavicle shaft fracture: A case report

In adults, brachial plexopathy due to clavicle fractures is rare and is most commonly caused by nonunion, mal-united fragments, hypertrophic callus, or pseudoaneurysm of the subclavian artery or vein. Conservative treatment of nondisplaced and displaced clavicle shaft fractures in adults usually produces satisfactory outcomes. This article presents a case of a 82-year-old man who sustained a closed, comminuted midshaft left clavicle fracture complicated by brachial plexus injury secondary to pseudoaneurysm of the left subclavian artery. Initially, the fracture was treated conservatively. However, he returned 5 days later with left brachial plexopathy. Computed tomography angiogram confirmed left subclavian artery pseudoaneurysm secondary to the fracture. The patient had endovascular stenting of the left subclavian artery to exclude the aneurysm. 12 weeks later, he had malunited clavicle and no improvement in brachial plexus function. 16 weeks after the injury, he had left brachial plexus exploration, decompression and open reduction and internal fixation of his left clavicle mal-united fracture. 4 weeks post operative, patient started to develop signs suggestive of significant re-innervation.

Resection of a giant mycotic left subclavian pseudoaneurysm

Subclavian artery pseudoaneurysm due to intravenous drug use is a rare pathologic entity. A 6.6-cm left subclavian artery pseudoaneurysm immediately distal to the origin of the vertebral artery was discovered in a 39-year-old man with neck swelling, bacteremia, and a history of intravenous drug use. The pseudoaneurysm was resected through a median sternotomy and left supraclavicular incision, without reconstruction. This operative approach was opted for given the presence of infection and the ongoing intravenous drug use.

Giant Bleeding Pseudo-aneurysm of left Sub-clavian Artery Complicating Neurologic Impairment: Management Challenges (Case Report)

Subclavian artery pseudoaneurysms are rare and occur mostly as a consequence of an inadvertent arterial puncture during central venous catheterization, endovascular therapeutic procedures or after penetrating or blunt trauma. They usually have a late clinical presentation, with pain, swelling or other compressive symptoms. We present a 40-year old man farmer who presented to our service with prior 14 days and 12 days history of left chest upper chest swelling and inability to use the left upper limb respectively, all on account of injury. He went on a night alcohol binge, got drunk and while getting to his sitting room slipped and fell on a nearby glass center table. He had a deep cut on the left upper anterior chest wall. There was immediate profuse spurting bleeding with estimated blood loss of 800 ml. After delay in definitive treatment due to financial constraint the aneurysm increased in size, ruptured and rebled profusely leading to syncope. He was managed by Doppler ultrasound, median sternotomy and subclavian artery exploration to achieve proximal and distal vascular control. Sac was entered into via an infraclavicular transverse incision, heamatoma manually evacuated, bleeding site isolated and secured. He received 5 units of blood. Postoperative course was uneventful as he was managed with analgesics, antibiotics, haematinics and physiotherapy. Power in the upper limb has improved to 3 around the shoulder, 2 around the elbow and 1 around the wrist.

Subclavian Artery Pseudoaneurysm following Stab Injury and Its Surgical Approach: A Case Report and Literature Review

Penetrating injuries to the subclavian arteries as well as post traumatic pseudoaneurysm involving Subclavian artery (SCA) are very much uncommon. We present one case of a 21 year-old male sustained a physical assault with a post stab injury left subclavian artery pseudoaneurysm. He was referred to our facility, two days after sustaining a penetrating chest trauma over left infraclavicular area of the chest. The presentation, diagnostic procedures and surgical approach for management of this very rare injury are discussed.

Open Surgical Approach for Type II Endoleak in Subclavian Artery Pseudoaneurysm Presented With Neurological Symptoms After Endovascular Repair

We present a rare case of a 10-cm right subclavian artery pseudoaneurysm, with slow growth over 4 years after a traumatic fracture of the right clavicle. The patient had multiple prior endovascular attempts of embolization and stenting at other hospitals; despite this the pseudoaneurysm continued to grow and caused mass effect and neurologic symptoms. We present our open approach for the repair and a review of literature.

Transient ischemic attack and ischemic upper limb in a case of subclavian artery pseudoaneurysm due to complicated clavicular bone fracture, a rare encounter

Background: Subclavian pseudoaneurysm is a rare sequalae of untreated ipsilateral clavicular bone fracture and may be complicated with distal embolization, causing an acute ischemia of ipsilateral upper limb. Case Presentation: We present a challenging case of subclavian pseudoaneurysm who was later discovered to have a previously missed clavicular bone fracture. The case was complicated with concurrent recurrent ischemic limb and transient ischemic attack of the brain. Conclusion: Although subclavian artery pseudoaneurysm as a cause for transient ischemic attack has not been described in literature, we believe that our case has highlighted the possibility of such association.

Redefining the morphometry of subclavian vessels for clavicle fracture treatments.

Clavicle fractures are common injuries in adults and children. Although neurovascular damage is rarely seen, acute subclavian artery pseudoaneurysms and injuries to subclavian vessels were reported for closed fractures of the clavicle. The aim of this study was to identify the morphological details of the subclavian vessels and their relation to the sternoclavicular joint and body of the clavicle. 127 patients (66 females and 61 males) were evaluated using reconstructed three-dimensional computed tomographic angiographies. The point at which the subclavian artery crossed posterior to the clavicle was detected as a landmark. The medio-lateral distance between the sternal end of the clavicle, landmark, antero-posterior distance between the clavicle and the subclavian artery, diameter of the artery and vein, angle between the subclavian artery and vein, distance of the subclavian vein to the subclavian artery and the clavicle at the landmark were measured. Measurements were compared according to gender and right and left sides, and age correlation was determined. Morphometric relationship between the subclavian vessels and clavicle presented differences between genders. We measured the antero-posterior distance between the subclavian artery and the clavicle to be less than 1cm (0.91cm). The subclavian artery travelled longer distances in men than women to reach the point that it crossed the clavicle. Our results demonstrated that the subclavian artery does not pass from the inferior margin of the clavicle, thus, superior plate osteosynthesis does not have any risk to injury against the subclavian vessels during the management of the clavicle fractures.
