ABSTRACT

Medical evacuation (MEDEVAC) from a combat zone requires complex decision-making and coordination of assets. A MEDEVAC helicopter team transports not only battle-injured patients but also patients with urgent non-battle-related medical diagnoses from extremely remote locations and are at the mercy of terrain, weather, and enemy contact. The military represents a young population particularly susceptible to venous thoracic outlet syndrome (vTOS) given the rigorous physical activity demands. Current literature supports immediate anticoagulation and surgical decompression within 14 days of diagnosis of vTOS to prevent long-term morbidity. Presented is a case of service member with vTOS presenting at an extremely remote military clinic who underwent a prompt evacuation ∼7,000 miles utilizing rotary-wing transport, followed by three to four more fixed-wing flights to a military treatment facility in the United States. Immediate recognition and ultrasound of this patient to confirm vTOS upon presentation and effective communication to non-medical military commanders and the receiving medical personnel at each Echelon was necessary to ensure an expedited evacuation. The surgeons treating this patient recommend prompt evacuation of deployed service members with suspected vTOS, venogram at the Role 3 if ultrasound is inconclusive, anticoagulation, and return to a Role 4 CONUS facility for definitive surgical management within 14 days. This case is an example of the efficiency of the military MEDEVAC system on a global scale, ensuring optimum medical care for all service members deployed.

ABSTRACT

Acute type I aortic dissection is a life-threatening emergency with potentially devastating complications, including end-organ malperfusion. Early detection of malperfusion with intraoperative imaging allows for efficient transition to appropriate interventions. We present a case of a 65-year-old male with acute type I aortic dissection who underwent emergent surgical repair of the aortic root and hemiarch followed by acutely worsening distal malperfusion. The use of intraoperative transesophageal echocardiography played a critical role in visualizing diversion of flow to the false lumen, prompting urgent vascular surgery consultation and life-saving thoracic endovascular aortic repair.

ABSTRACT

Ocular ischemic syndrome is a rare complication of carotid arterial disease that can lead to irreversible vision loss. The disease is related to ocular hypoperfusion secondary to carotid stenosis. Carotid endarterectomy (CEA) has been proven to reduce the risk of embolic stroke in specific patient populations; however, the role of CEA in the treatment of ocular ischemic syndrome or other flow-related symptoms is less well defined. We present a case of ocular ischemic syndrome successfully treated with carotid endarterectomy, and summarize the current literature regarding management of ocular ischemic syndrome.

ABSTRACT

BACKGROUND: The treatment of venous thoracic outlet syndrome (VTOS) requires surgical decompression often combined with catheter-directed thrombolysis and venoplasty. Surgical options include transaxillary, supraclavicular, or infraclavicular approaches to first rib resection. The optimal method, however, has yet to be defined. The purpose of this study is to compare the outcomes of patients who underwent infraclavicular versus supraclavicular surgical decompression for VTOS. METHODS: A retrospective review of patients who underwent surgical management for VTOS from December 2010 to November 2017 was performed. During the study period, supraclavicular and infraclavicular approaches were chosen according to surgeon preference. Patient demographics, pre- and postdecompression interventions, perioperative outcomes for each group of patients were analyzed. RESULTS: Thirty patients underwent surgical management of VTOS, of which 15 (50%) underwent infraclavicular decompression and 15 (50%) supraclavicular decompression. The mean age of patients was 32.1 ± 13.6 years and 80% were male. Twenty-six patients (86.7%) presented with thrombotic VTOS. Acute axillosubclavian vein thrombosis was present in 20 (76.9%) of these patients, 10 patients in each group. Subacute or chronic thrombosis was encountered in the remaining 6 (23%) patients, 2 patients in the infraclavicular group and 4 patients in the supraclavicular group. Preoperative thrombolysis was utilized in 7 (46.7%) and 6 (40%) patients in the infraclavicular and supraclavicular groups, respectively (P = 1.00). Patients without postdecompression venography were removed from analysis and included 1 patient in the infraclavicular group and 5 patients in the supraclavicular group. Initial postdecompression venogram, prior to any endovascular intervention, demonstrated a residual axillosubclavian vein stenosis of greater than 50% in 6 (42.9%) patients in the infraclavicular decompression group and 7 (70%) patients in the supraclavicular decompression group (P = 0.24). Crossing the stenosis after surgical decompression was more easily accomplished in the infraclavicular group, 14 (100%) versus 5 (50%), (P = 0.01). Following endovascular venoplasty, calculated residual stenosis greater than 50% was found in 0 (0%) and 3 (30%) patients in the infraclavicular and supraclavicular approaches, respectively (P = 0.047). Infraclavicular thoracic outlet decompression was associated with fewer patients with postoperative symptoms, 0 of 15 (0%) versus 8 of 15 (53.3%), (P = 0.0022), and infraclavicular thoracic outlet decompression demonstrated improved patency, 15 of 15 (100%) versus 8 of 15 (53.3%), (P = 0.028) at a mean combined follow-up of 8.47 ± 10.8 months. CONCLUSIONS: Infraclavicular thoracic outlet decompression for the surgical management of VTOS was associated with fewer postoperative symptoms and improved axillosubclavian vein patency compared to the supraclavicular approach. Prospective analysis is warranted to determine long-term outcomes following infraclavicular decompression.
