Axillary artery transection after shoulder dislocation

Axillary Artery Transection and Brachial Plexus Injury After Open Inferior Glenohumeral Dislocation: A Case Report

CASE

A judo athlete presented with an open inferior shoulder dislocation that occurred during competition. Examination revealed a transection of the axillary artery and neuropraxia of the posterior cord. Neuropraxia was resolved within 2 weeks. The axillary artery was repaired with a femoral vein graft. He regained full strength, range of motion, and function at 8 months.

CONCLUSION

Inferior glenohumeral dislocations are rare, and their management can be complicated by vascular and neurological injuries. We emphasize the importance of examination, diagnosis, and treatment of neurovascular pathologies to avoid catastrophic outcomes.

Endovascular Repair of Transected Axillary Artery via Snare Assisted Through and Through Femoral to Brachial Artery Access

Axillary artery injury is a rare but complex surgical problem that often requires challenging exposures, lengthy operations, and morbid outcomes for repair. For these reasons, endovascular repair is an attractive alternative as it obviates many of the challenges present with open repair. While pseudoaneurysms, dissections, and short segment injuries with limited arterial disruption are regularly treated endovascularly, complete arterial transections are almost exclusively treated with open repair as obtaining wire access across the site of injury is often not possible. Here we report a case of successful endovascular repair of a completely transected axillary artery with the use of snare assistance to obtain through and through femoral to brachial artery access. This ultimately allowed for covered stent deployment across the axillary transection restoring distal blood flow. Snare assistance in obtaining through and through access across areas of complete transection can allow for increased use of endovascular repair.

Fatal Outcome After Reduction of a Superior Shoulder Dislocation, A Case Report and Literature Review: A Case Report and Literature Review

CASE

An 81-year-old woman presented a superior glenohumeral dislocation after a low-energy fall, with a mechanism of axial load while the shoulder was in adduction and extension. After successful closed reduction, the patient presented sudden symptoms of severe vascular injury with a protruding axillary hematoma and hypovolemic shock.

CONCLUSION

Superior shoulder dislocations and vascular injuries are extremely rare among shoulder dislocations, especially after low-energy trauma. Vascular injuries may result in limb compromise and death. We highlight the importance of high clinical suspicion, particularly in superior dislocations, and the importance of prompt management of vascular complications to avoid catastrophic outcomes.

<p>Upper Limb Salvage of a Mangled Limb with Reconstruction of Brachial, Ulnar and Radial Arteries Using an Extremely Long Reversed Bifurcated Great Saphenous Vein: A Case Report with Long-Term Follow-Up</p>

Acute elbow dislocation complicated by arterial injury of upper limb is rare but serious injury. We present the case about destructive injury of brachial, ulnar, and radial arteries with an open posterior dislocation of the right elbow, and a 25cm long reversed bifurcated great saphenous vein graft was applied for arterial reconstruction. The patient had obvious distal pulses after the operation. Ten years’ follow-up showed the good function of the right arm. Using an extremely long vein graft for the upper limb arterial reconstruction is challenging but feasible and provides good results.

Mind the gap: A novel endovascular technique to repair a transected vessel

Level one trauma centers experience horrific injuries on a regular basis. Blunt or penetrating trauma causing vascular injuries are treated by surgeons and interventional radiologists. When a blood vessel is completely transected, the ends of the vessel retract and vasospasm occurs as a normal survival response. When this phenomenon occurs, it is sometimes impossible to reattach the two ends of the injured vessel by surgical means and a bypass graft is often required. However, from an endovascular perspective, covered stents can serve as a vascular bypass as well. The limiting factor with an endovascular approach is the ability to successfully gain wire access across the injured vessel. The technique described in this manuscript describes a "rendezvous" method of repairing a transected axillosubclavian artery from a high-speed motorcycle accident using a steerable microcatheter. Initially, multiple failed attempts to cross the injured vessel were encountered despite using a wide variety of conventional guidewires and catheters. A steerable microcatheter was then used to safely and effectively navigate more than 15 cm through soft tissue to the opposite end of the vessel. In this critically ill patient, this technique significantly reduced the procedural time when compared to our previous experiences repairing arterial transections using traditional catheters.

Arterial Injury in the Upper Limb Resulting from Dog Bite

Dog bites in the upper limbs have particular significance, because despite the small size of the puncture wounds, penetration is deep, causing serious injuries to deeper structures. There is currently very little data relating to upper extremity dog bite arterial injury. We present the case of a 32-year-old man who sustained a dog bite injury to his right arm, leading to direct puncture and spasm of the brachial artery. He was successfully treated with a jump bypass graft to the right brachial artery, with the use of the reversed ipsilateral cephalic vein as a conduit. We identified 34 cases in the literature reporting upper limb arterial injury secondary to dog bite. Twenty-two cases in the literature detailed axillobrachial artery damage (65%), 24% radial artery, 3% ulnar artery, and 9% combined. Presentation was most commonly with diminished pulses found in at least 45% of the patients. Arterial thrombosis occurred in 29% of cases of single artery injury, transection in 15%, intimal tear in 9% of cases, and undisclosed in 44%. Management most commonly included interposition graft (47%) and primary repair (20%), while 15% did not undergo surgical intervention, 9% underwent ligation, and 3% were treated with thromboembolectomy. Follow-up data for these patients are scarce, with some experiencing residual neurological deficit. This report highlights the importance of prompt recognition and treatment of vascular injury following dog bite to attain an optimal outcome and minimize complications.

Arterial Injury in the Upper Extremity: Evaluation, Strategies, and Anticoagulation Management

Trauma to the upper extremity can present with an associated arterial injury. After patient stabilization, thorough assessment with physical examination and various imaging modalities allows accurate diagnosis of the specific arterial injury. After diagnosis, efficient treatment is necessary to allow limb salvage. Treatment options include ligation, primary repair, graft reconstruction, endovascular repair, and amputation. The final treatment rendered is frequently dependent on injury location and mechanism. With any of the treatment options, complications may occur, including thrombosis. Currently, no validated anticoagulation protocol has been established for managing arterial injuries in the upper extremity.

Axillary artery transection and bilateral pulmonary embolism after anterior shoulder dislocation: case report

Introduction: Anterior shoulder dislocation can be associated with vascular and neurological complications. However, axillary artery injury associated with shoulder dislocation is rare and extremely rare without bone fracture. An early diagnosis of these complications allows predicting long-term functional outcomes.

Methods: This article reports the case of a 66-year-old patient who presented an anterior shoulder dislocation after a ski fall without any neurological dysfunction or pulse deficit.

Results: The first reduction attempts were unsuccessful and during the new attempt, we observed a hematoma. A CT scan showed a disruption of the axillary artery and a bilateral pulmonary embolism.

Conclusion: Neurovascular injury must be systematically sought before and after reduction, and a multidisciplinary approach is always necessary.

Brachial Artery Reconstruction in Trauma Using Reversed Arm Vein from the Injured Upper Limb

BACKGROUND

Brachial artery repair may be technically challenging with a paucity of guidelines. The use arm vein (AV) from the traumatized limb is herein described.

METHODS

Data were prospectively collected from 2002 to 2016 on brachial artery injury including age, sex, mechanism/site of injury, and repair technique. Categories included AV and non-arm vein (NAV) groups. One-year outcomes were noted.

RESULTS

All 31 cases studied were of men with an age range of 16 to 73 years (mean = 28). Injuries included 13 gunshots, 7 stabbings, 6 glass injuries, 2 dislocated elbows, 1 crush, 1 impalement, and 1 avulsion. Site of injuries included the antecubital region in 25, midbrachial in 5, and proximal brachial in 1, with 4 associated fractures. Repair was done using reversed AV from the traumatized limb in 15 cases and NAV in 16. In the AV group, the adjacent basilic vein was used in 9 cases, the adjacent cephalic vein in 3, and the distal (or wrist area) cephalic vein in 3. The limb salvage rates in the AV versus NAV groups were 100% and 94%, respectively (Fisher's exact t test, P = 1.00), with no major technique-related complications.

CONCLUSIONS

The outcomes of using reversed AV from the traumatized limb are equivalent to those of other standard techniques such as primary repair, polytetrafluoroethylene, or reversed great saphenous vein, with a 1-year limb salvage rate of 100%. Additionally, advantages include decreased wound complications, better vein graft--artery caliber match, and shorter operating times while maintaining acceptable patency rates.
