Abstract
We describe 20 patients, aged between 43 and 88 years, with delayed nerve palsy or deepening of an initial palsy caused by arterial injury from low-energy injuries to the shoulder. The onset of palsy ranged from immediately after the injury to four months later. There was progression in all the patients with an initial partial nerve palsy. Pain was severe in 18 patients, in 16 of whom it presented as neurostenalgia and in two as causalgia. Dislocation of the shoulder or fracture of the proximal humerus occurred in 16 patients. There was soft-tissue crushing in two and prolonged unconsciousness from alcoholic intoxication in another two. Decompression of the plexus and repair of the arterial injury brought swift relief from pain in all the patients. Nerve recovery was generally good, but less so in neglected cases. The interval from injury to the repair of the vessels ranged from immediately afterwards to 120 days. Delayed onset of nerve palsy or deepening of a nerve lesion is caused by bleeding and/or impending critical ischaemia and is an overwhelming indication for urgent surgery. There is almost always severe neuropathic pain.

Abstract
Penetrating injuries with resultant trauma to the subclavian and axillary arteries have traditionally been evaluated with direct contrast angiography. Physical examination has a low sensitivity for detection of vascular injuries in stable patients and surgical exploration is challenging. With advancements in CT technology, a less invasive and more rapid approach in evaluating arterial injury is now being utilized in many trauma centers. This article will depict the CT angiographic signs of subclavian and axillary artery injuries.

Abstract
INTRODUCTION Injury to the subclavian and axillary arteries is uncommon. Standard surgical techniques require wide exposure and dissection in traumatised areas which is often challenging and associated with significant morbidity, and mortality ranges from 5 to 30%. We report our experience with the endovascular treatment of these injuries. METHODS We retrospectively studied patients with blunt or penetrating (including iatrogenic) injuries to the subclavian or axillary artery between January 2000 and September 2004. Demographic data, mechanism of injury, concomitant injuries, angiographic findings, and treatment method and outcome were recorded. Nine patients with injury to the subclavian or axillary artery were seen at our institution during the study. Two patients underwent interventions, seven patients had lesions amenable to endovascular repair. RESULTS Immediate success was obtained in all procedures (100%). All patients continue to have patent grafts with a follow-up ranging from 3 to 48 months (mean 22.6 months). The procedure-related complication was the need for a brachial artery pseudoaneurismectomy at the site of device insertion in one patient (14.7%). None of the patient developed a device fracture. CONCLUSION Endovascular stent-grafts offer an effective, less invasive alternative to standard techniques in treating traumatic arterial lesions, resulting in shorter procedure time and less blood loss than previously reported.

Abstract
The management of severe injured patients requires life-threatening lesions research, especially potential haemorrhagic lesions. The haemorrhagic shock is a rare but serious complication of shoulder girdle traumas. We report in this study the clinical and paraclinical signs that lead us to take care from such evolution.

Abstract
Injuries of the subclavian and proximal axillary arteries are potentially devastating but account for a minority of vascular injuries presenting to trauma centers in the United States. We have reviewed our recent experience with management of subclavian and axillary artery injuries in a state-designated level 1 academic trauma center and report four cases that illustrate the typical arterial injury patterns and the entire therapeutic armamentarium in its current iteration. Subclavian and proximal axillary artery injuries present as interesting surgical problems. A high index of suspicion for vascular injuries should be maintained given the mechanism and proximity to major vasculature. Consideration should always be given to the least invasive treatment options in stable patients. Awareness of multiple therapeutic modalities and indications for each should be an integral part of every surgeon's armamentarium. As with all vascular intervention, eventual failure is the rule rather than the exception; therefore, plans for longitudinal surveillance should be made independent of the technique used to treat the injury.

Abstract
OBJECTIVE Cardiopulmonary bypass via the axillary artery is frequently used especially in aortic dissections. With an increased use of this technique problems were recognized too. We describe the technical problems and complications associated with axillary artery cannulation. METHODS Sixty-five patients underwent cannulation of the axillary artery. The indication for operation was acute aortic dissection type A in 57%, chronic aortic dissection in 8%, aortic aneurysm in 18%, pseudoaneurysm in 3%, and others in 14%. RESULTS Technical problems and complications occurred in 14%, and in 11% the perfusion had to be switched to either femoral (n=5) or aortic cannulation (n=2). Arterial damage or dissection of the axillary artery or the aorta occurred in 0% of the sidegraft technique, whereas they were found in 9% with direct cannulation (P=n.s.). Cannulation problems or insufficient CPB flow due to a narrow vessel occurred in 0% of the sidegraft technique, whereas they were found in 4% with direct cannulation (P=n.s.). Malperfusion in aortic dissections occurred in 20% of the sidegraft technique, whereas they were found in 0% with direct cannulation (P=0.016). No postoperative complications related to axillary cannulation which were evaluated by clinical examination, such as brachial plexus injury, axillary artery thrombosis or local wound infection were observed. CONCLUSIONS Although axillary artery cannulation is an attractive alternative to femoral cannulation there needs to be an alertness for technical problems. Different complications occur with either direct cannulation or the sidegraft technique and at present it remains the surgeons preference which technique for axillary artery cannulation is used.

Abstract
An 82-year-old man presented with massive external bleeding from the puncture site after placement of a deep venous catheter in the right subclavian vein. Emergent angiography revealed contrast extravasation along the central venous catheter tract due to perforation of the right thoracoacromial artery. Superselective catheterization of the bleeding artery followed by microparticle embolization definitively stopped the hemorrhage. During follow-up no recurrence of external bleeding was noted. Percutaneous embolization using microparticles is an effective tool to definitively treat iatrogenic arterial hemorrhage as a complication of deep venous catheter placement.

Abstract
BACKGROUND Penetrating injuries to the axillary and subclavian vessels are a source of significant morbidity and mortality. Although the endovascular repair of such injuries has been increasingly described, an algorithm for endovascular versus conventional surgical repair has yet to be clearly defined. On the basis of institutional endovascular experience treating vascular injuries in other anatomic locations, we defined an algorithm for the management of axillosubclavian vascular injuries. Subsequently, a near decade long experience with the management of axillosubclavian vascular injuries was retrospectively analyzed, so as to more accurately assess the true feasibility of endovascular treatment in these patients. METHODS We defined a management algorithm that included (1) indications, (2) relative contraindications, and (3) strict contraindications for the endovascular repair of axillosubclavian vascular injuries. Anatomic indications for endovascular repair were restricted to relatively limited axillosubclavian injuries (pseudoaneurysms, arteriovenous fistulas, first-order branch vessel injuries, intimal flaps, and focal lacerations). Relative contraindications for endovascular repair included injury to the axillary artery's third portion, substantial venous injury (eg, transection), refractory hypotension, and upper extremity compartment syndrome with neurovascular compression. Strict contraindications to endovascular repair included long segmental injuries, injuries without sufficient proximal or distal vascular fixation points, and subtotal/total arterial transection. Within the context of these definitions, we retrospectively reviewed 46 noniatrogenic subclavian and axillary vascular injuries in 45 patients identified by a prospectively maintained computer registry during a 9-year period. Presentations were reviewed concurrently by two endovascular surgeons, and potential candidates for endovascular management were defined. RESULTS Among 46 total case presentations and among the 40 patients who maintained vital signs on presentation, 17 were potentially treatable with endovascular therapy. Among the cohort of 40 presentations, the most common contraindications to endovascular therapy were hemodynamic instability (n = 10), vessel transection (n = 7), and no proximal vascular fixation site (n = 3). CONCLUSIONS Despite growing enthusiasm for endovascular repair of injuries to the axillary and subclavian vessels, realistic clinical presentation and anatomic locations restrict the broad application of this technique at present. In our experience, less than but approaching 50% of all injuries encountered could be addressed with an endovascular approach. This percentage will increase during the upcoming decades if the endovascular technologies available in hybrid endovascular operating rooms uniformly improve.

Abstract
Injury to the axillary artery following anterior shoulder dislocation is a very rare occurrence. This review serves to illustrate the now classical case of an elderly gentleman with a recurrent dislocation, transection of the axillary artery and its invariable association with a severe brachial plexus lesion, which is the most important determinant of long-term disability. It also highlights the pathognomic triad of anterior shoulder dislocation, expanding axillary haematoma and diminished peripheral pulse, to highlight awareness of this important injury. The literature on this injury has been reviewed and recommendations for the immediate and early post-operative investigation and management have been brought up to date in line with current thinking.

Abstract
Axillary artery injury from blunt trauma to the shoulder is uncommon. Fracture of the neck of the humerus is a rare cause of injury to the axillary artery. Four cases of axillary artery thrombosis from humeral neck fracture are reported. Each of the first 2 patients presented with a pulseless and acutely ischemic limb after a trivial fall. A repair of the axillary artery with saphenous vein interposition graft was performed in the first patient. The extremity was salvaged, but a residual radial and ulnar neurologic deficit persisted. The second patient presented with a pulseless insensate upper extremity accompanied by motor loss. He underwent primary axillary artery repair. Still early in his postoperative course, he has had global brachial plexopathy and is undergoing intensive physical therapy. The third patient had a delayed presentation of brachial plexopathy and sympathetic reflex dystrophy. Arterial reconstruction was not required owing to excellent collateralization. The fourth patient presented with a cool pulseless extremity. His recovery is nearly complete after bypass of the axillary artery with a reversed saphenous vein graft. In addition, a review of the literature revealed 24 cases of axillary artery injury associated with humeral neck fracture. The mean age was 66.6 years. The most common mechanism of injury was a fall (79%). Thirteen patients (46%) presented with a neurologic deficit. Acute ischemia was present in 68%. Physical examination predicted the arterial injury in all but 1 patient. The injured axillary artery was repaired in 26 cases. Revascularization by an interposition graft was the most common procedure. All grafts and reanastomoses were patent and led to limb salvage. Of 9 primary repairs, 3 amputations were performed. Although limb salvage rate was 89%, a good functional outcome was obtained in only half of the patients. A high index of suspicion is required for early diagnosis of axillary artery injury. Despite excellent results of vascular reconstruction, the outcome remains determined by the excessive neurologic morbidity. Recognition of the associated brachial plexus injury is essential to improve the functional outcome of this unusual arterial injury.

Abstract
We present a case of a 68-year-old female patient who had an interscalene nerve block (ISB) complicated by compression of her brachial plexus by a pseudoaneurysm. The complication occurred after the patient received an ISB as anesthesia for an outpatient shoulder procedure. Review of this complication should alert surgeons to consider this diagnosis as a possibility in patients with postoperative pain and/or neurologic compromise after receiving an ISB.

Abstract
OBJECTIVE To describe 3 cases of vascular injuries due to orthopaedic procedures. CLINICAL PRESENTATION AND INTERVENTION Of 242 vascular injuries, 3 were due to orthopaedic screws. The 1st patient presented with a late complication (after 3 years) of an orthopaedic screw placed in close proximity to the axillary artery that with time got eroded and leaked to form a false aneurysm which later caused embolisation to the arm and limb ischaemia. The 2nd and 3rd cases were due acute ischaemia following the orthopaedic procedures. Both were injuries to the popliteal artery, one after a long screw and the other after drilling the tibia. The aneurysm of the 1st case was resected, the screw was removed and a reversed segment of the right long saphenous vein was used to repair the axillary artery. In the 2nd patient, a bypass of the left popliteal artery to the tibio-peroneal trunk was performed using a reversed 12-cm-long saphenous vein graft retrieved from the right thigh. In the 3rd patient, the right popliteal vein was ligated, and a reversed 25-cm-long saphenous vein graft retrieved from the left thigh was used for a femoro-popliteal bypass. For the 3 patients, postoperative recovery was unremarkable. Pulses were present within 6-10 months of follow-up. CONCLUSIONS Whenever limb vascularity is compromised after an orthopaedic procedure, a high index of suspicion for an arterial injury should be exercised and prompt referral to the vascular service is mandatory. Repair of injured vessels with a saphenous vein graft provides excellent long-term results.

Abstract
PURPOSE The purpose of this study was to examine the neurovascular structures at risk during placement of glenohumeral arthroscopy portals using an outside-in technique. TYPE OF STUDY Anatomic cadaveric study. METHODS Five fresh-frozen cadaveric specimens were used in this study. Each shoulder was mounted on a custom-designed apparatus allowing shoulder arthroscopy in a lateral decubitus position. The following portals were established using an outside-in technique and marked using an 18-gauge spinal needle: posterior, posterolateral, anterior, 5-o'clock, anterosuperolateral, and Port of Wilmington. Each specimen was carefully dissected after the procedure, and the distance from each portal site to the adjacent relevant neurovascular structures (axillary nerve, musculocutaneous nerve, lateral cord of the brachial plexus, cephalic vein, and axillary artery) was measured using a precision caliper. RESULTS Except for the cephalic vein, all of the neurovascular structures were more than 20 mm away from all the portals evaluated. When creating either an anterior portal or a 5-o'clock position portal, the mean distance from the portal to the cephalic vein was 18.8 mm and 9.8 mm, respectively. In one anterior portal, a direct injury to the cephalic vein occurred. CONCLUSIONS Our study suggests that shoulder arthroscopy portals placed in an outside-in fashion are unlikely to produce neurologic injury. However, the cephalic vein is at risk during placement of an anterior or 5-o'clock position portal, although probably with minimal subsequent patient morbidity. Placing portals in an outside-in fashion guarantees the correct angle of approach, with minimal risk to adjacent neurologic structures. CLINICAL RELEVANCE This study shows the safety of standard and accessory glenohumeral arthroscopy portals.

Abstract
BACKGROUND Ideal perfusion during ascending aorta-arch surgery should allow easy implementation of antegrade cerebral perfusion while avoiding atheroembolization or false lumen perfusion in dissections. We report favorable experience with direct axillary artery cannulation. METHODS Between 1999 and 2003, 284 patients with a mean age of 62.2 years (25 to 85), underwent axillary artery cannulation using a right angle wire-reinforced catheter. During this interval, attempted axillary cannulation was abandoned in only 14 patients because of inadequate backflow or other complications. Eighty-five patients were female. Severe aortic arteriosclerosis or degeneration was present in 209, aortic dissection in 63, and Marfan disease or aortitis in 12. The Bentall procedure was done in 144 patients, arch replacement in 86, the Yacoub procedure in 18, thoracoabdominal aneurysm repair in 16, and coronary artery bypass grafting in 20. Reoperations were at 30.2%. RESULTS Adverse outcome (hospital death or permanent stroke) occurred in 6.6% (n = 19). Thirteen patients (4.6%) died before hospital discharge, and 13 patients (4.6%; 9 of whom died) suffered permanent stroke. Transient neurologic dysfunction occurred in 9.2% (n = 26). Mean duration of hypothermic circulatory arrest, used in 246 patients, was 26 +/-7 minutes. Mean duration of antegrade cerebral perfusion, used in 139 patients, was 47 +/- 23 minutes. In 93%, the right axillary artery was cannulated. Complications included 2 cases (0.7%) of brachial plexus injury (one transient), and 3 (1%) of localized dissection. CONCLUSIONS Our results suggest that axillary artery cannulation, successful in 95% of patients, may be the optimal technique for reducing perfusion-related morbidity and adverse outcome in operations for acute dissection, atherosclerotic, and degenerative aneurysmal disease. It deserves serious consideration in all patients older than 65 requiring cardiopulmonary bypass.

Abstract
PURPOSE The purpose of this study was to examine the neurovascular structures at risk when performing surgery about the coracoid. TYPE OF STUDY Anatomic cadaveric study. METHODS Five fresh-frozen cadaveric shoulders were dissected to determine the dimensions of the coracoid and the distance from the coracoid to adjacent neurologic and vascular structures. The minimal distance from the coracoid tip to the axillary nerve, musculocutaneous nerve, the lateral cord of the brachial plexus, and the axillary artery was measured using a precision caliper. Similarly, the minimal distance from the base of the coracoid to the axillary nerve, musculocutaneous nerve, the lateral cord of the brachial plexus, and the axillary artery was measured. RESULTS The coracoid tip was defined as that portion of the bone that was distal to the "elbow" of the coracoid. Results showed that the mean width (medial-to-lateral dimension in the plane of the subscapularis tendon) of the coracoid tip was 15.9 +/- 2.2 mm, and the mean length of the coracoid tip was 22.7 +/- 4.5 mm. The mean thickness of the coracoid tip at its midportion was 10.4 +/- 1.5 mm. The portion of the coracoid tip which was closest to the neurovascular structures was the anteromedial portion of the coracoid tip. The distance from the anteromedial portion of the coracoid tip to the axillary nerve, the musculocutaneous nerve, the lateral cord, and the axillary artery was 30.3 +/- 3.9 mm, 33.0 +/- 6.2 mm, 28.5 +/- 4.4 mm, and 36.8 +/- 6.1 mm, respectively. Similarly, the portion of the base of the coracoid that was closest to the neurovascular structures was its anteromedial portion. The shortest distance from the anteromedial aspect of the base of the coracoid to the axillary nerve, the musculocutaneous nerve, the lateral cord, and the axillary artery was 29.3 +/- 5.6 mm, 36.5 +/- 6.1 mm, 36.6 +/- 6.2 mm, and 42.7 +/- 7.3 mm, respectively. CONCLUSIONS Procedures about the coracoid are relatively safe procedures. The lateral cord of the brachial plexus is at greatest risk during dissection about the tip of the coracoid, and the axillary nerve is at greatest risk during dissection about the base of the coracoid. The safety of arthroscopic coracoplasty or interval releases is further increased by the fact that most of the work is performed on the lateral aspect of the coracoid, which is even further away from the neurovascular structures. CLINICAL RELEVANCE This study quantifies the relative risk of injury to neurovascular structures during arthroscopic surgery about the coracoid.

Abstract
During axillary brachial plexus block for hand surgery, the axillary artery was accidentally punctured. After skin disinfection of the operation site a livid discoloration of the hand appeared. The initial intention of stopping surgery and performing an angiography for clarification of the suspicion of a vessel lesion was dismissed after recording the pulse at the wrist and all fingertips employing a pulsoximeter. Further investigation showed that the livid discoloration of the hand was a product of the interaction of the octenidin solution used for pre-operative hand disinfection with the polyvidone-iodine solution used for surgical skin disinfection. This case report shows that interactions of topically administered pharmaceuticals have to be taken into consideration. Lack of knowledge might lead to unnecessary and unjustified diagnostic procedures which imply additional costs and dangers for the patient.

Abstract
The neurovascular bundle anatomy in the upper arm displays changing relationships of nerve and vascular structures along short segments. Fibrous tissues segregate these elements into enclosed compartments allowing for specific patterns of injury. We report a patient with a iatrogenic brachial artery injury in this region who featured combined median and MAC neuropathies, which were consistent with complete axonotmesis on neurophysiological assessment. Increased intracompartmental pressure may have led to nerve injury either thorough an ischemic mechanism or to focal compression. Recognition of this unusual pattern of nerve damage is important, since injury can be accurately localized to the midportion of the neurovascular compartment in the upper arm.

Abstract
Thoracic duct injury is a rare but serious complication following chest surgeries and major neck dissections. Clinically, it can present as cervical chylous fistula, chylothorax or chylopericardium. Without treatment, the mortality is up to 50% and thus, early aggressive therapy is indicated. Traditional conservative management includes low-fat diet, parenteral nutrition, careful monitoring of fluid and electrolytes, and drainage of the neck wound or chylothorax. Patients with failed conservative management require definitive treatment in the form of ligation of the thoracic duct, which has traditionally been done by thoracotomy. The advent of Video-Assisted-Thoracoscopic-Surgery (VATS) over the last decade has changed the approach towards the management of numerous chest diseases. Thoracoscopic ligation of the thoracic duct has also been reported. We report herein a case of postoperative cervical chylous fistula managed successfully by VATS thoracic duct ligation and present a systematic analysis of the English literature to highlight the current trends in the management of thoracic duct injury.

Abstract
Several factors may limit the success of conventional operative therapy for traumatic arterial injuries. In particular, the inaccessibility of the vascular lesion, anatomic distortion, and the inherent problems associated with operating in a traumatized and often contaminated field are among these limiting factors. As a result, endovascular therapy has emerged as an important potential alternative. This paper focuses on the application of endovascular therapy to the trauma patient, based on our experience and those previously published by other groups. Injuries to the carotid, femoral, axillary/subclavian and iliac arteries, as well as to the abdominal and thoracic aorta, have been successfully managed by stent-grafting. Despite the potential benefits of this mode of therapy, its long-term utility will depend on our ability to overcome certain limitations associated with the technique, and on careful patient selection.

Abstract
Droopy shoulder has been proposed as a cause of thoracic outlet syndrome. Two patients developed manifestations of neurovascular compression upon arm abduction, associated with unilateral droopy shoulder and trapezius muscle weakness caused by iatrogenic spinal accessory neuropathies following cervical lymph node biopsies. The first patient developed a cold, numb hand with complete axillary artery occlusion when his arm was abducted to 90 degrees. The second patient complained of paresthesias in digits 4 and 5 of the right hand, worsened by elevation of the arm, with nerve conduction findings of right lower trunk plexopathy (low ulnar and medial antebrachial cutaneous sensory nerve action potentials). Spinal accessory nerve grafting (in the first patient) coupled with shoulder strengthening physical exercises in both patients resulted in gradual improvement of symptoms in 2 years. These two cases demonstrate that unilateral droopy shoulder secondary to trapezius muscle weakness may cause compression of the thoracic outlet structures.

Abstract
INTRODUCTION Injury to the subclavian and axillary arteries is uncommon. Exposure of these vessels is associated with significant morbidity, and mortality ranges from 5% to 30%. Endovascular methods may offer an alternative approach to these technically challenging injuries. METHODS We retrospectively studied patients with blunt or penetrating (including iatrogenic) injuries to the subclavian or axillary artery between January 1, 1996 and July 30, 2002. Demographic data, mechanism of injury, concomitant injuries, angiographic findings, and treatment method and outcome were recorded. RESULTS Twenty-seven patients with injury to the subclavian or axillary artery were seen at our institution during the study. Twenty-three patients underwent interventions. Eleven patients required open repair; 12 patients had lesions amenable to endovascular repair. Depending on the preference of the surgeon, 5 patients with injuries amenable to endovascular repair underwent open repair, and 7 underwent endovascular repair. A Wallgraft endoprosthesis was used in all patients; two grafts were required in 1 patient. Endovascular repair was associated with shorter operative time (P =.04) and less blood loss (P =.01). One-year patency was similar between the two groups. CONCLUSION Covered stents are a feasible alternative to open repair in properly selected patients with subclavian or axillary artery injury, resulting in shorter procedure time and less blood loss.

Abstract
BACKGROUND Our purpose was to determine the accuracy of single-injection, retrograde transbrachial arteriography (RTBA), performed in the emergency room, for suspected axillosubclavian injuries. METHODS Thirty-three patients were prospectively assigned for RTBA. Clinical indications for RTBA included high-risk mechanism of injury, decreased (n = 19) or absent (n = 5) brachial pulse, neurologic deficits (n = 11), external or intrathoracic bleeding (n = 4), and bruit (n = 2). Brachial artery was cannulated with an 18-gauge catheter. A sphygmomanometer cuff was placed at the forearm and inflated to 250 mm Hg. Twenty milliliters of nonionic contrast media was injected countercurrent and a single anteroposterior chest radiograph was obtained. Small intimal flaps were followed by serial ultrasound. Surgical findings were used to establish RTBA accuracy. RESULTS RTBA was successfully performed in all cases. Arterial lesions were detected in 28 (84.8%) patients, including thrombosis (n = 8), arteriovenous fistula (n = 8), and false aneurysm (n = 7) as the most frequent lesions. A sensitivity of 96.5%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 80% were observed with RTBA. CONCLUSION We conclude that RTBA is a safe and accurate technique to be used in the emergency room for the rapid detection of axillosubclavian arterial injuries.

Abstract
Diffuse large B-cell lymphoma is a very common, highly invasive lymphoma, which typically presents as a rapidly enlarging symptomatic mass with local compression of vessels or airways, and often is involved with the peripheral nerves and the destruction of bone. Vascular invasion is extremely rare. We herein describe the case of a successfully treated 42-year-old man who presented with massive bleeding due to a rupture of the axillary artery and vein involvement due to lymphoma.
