Carotid Artery Entrapment by the Hyoid Bone-A Rare Cause of Recurrent Strokes in a Young Patient.
The search for etiology of stroke in a young patient may present a diagnostic challenge. In rare cases, chronic trauma to the carotid artery may be the cause of cerebral thromboembolic events. The hyoid bone lies in close proximity to the carotid artery bifurcation, and anatomic variants have been implicated in carotid compression, stenosis, dissection, and pseudoaneurysm. ⋯ The diagnosis can be confirmed by carotid duplex with provocative maneuvers. Partial hyoid resection is a safe and effective treatment to relieve recurrent symptoms. Hyoid bone entrapment may be an important and under-recognized cause of stroke in young adults.

Subclavian artery aneurysms associated with thoracic outlet syndrome (TOS) have traditionally been managed by open surgical reconstruction. Endovascular subclavian artery reconstruction is novel in the setting of arterial TOS (aTOS). Our objective is to report our results with endovascular subclavian artery reconstruction in aTOS patients over a 10-year period with attention to surgical approach and late results. ⋯ Our experience indicates that stent-graft reconstruction of subclavian artery aneurysms associated with aTOS is successful. This procedure was characterized by short surgical times, low blood loss, and no complications. It may be subject to late graft thrombosis or stenosis and requires life-long surveillance.

The natural history of the thoracic false lumen after coil embolization for type B aortic dissection (TBAD) treated by previous thoracic endovascular aortic repair (TEVAR) remains a matter of debate. The aim of this study is to assess the efficacy of coil embolization in promoting thoracic aortic remodeling of TBAD with persistent thoracic false lumen after TEVAR. ⋯ In this retrospective single center experience, the efficacy of coil embolization in promoting thoracic aortic remodeling of TBAD with persistent thoracic false lumen post-TEVAR appears to be limited, especially in patients with thoracic aneurysmal aortic dissection. Further studies are warranted to inform the optimal treatment strategy.

Hypothenar hammer syndrome (HHS) is an uncommon vascular syndrome of upper extremity. HHS should be considered in patients who are presented with digital ischemia. Distal ulnar artery compression at the level of Guyon's canal with trauma results in thrombus or aneurysm. It may be observed after repetitive chronic trauma or acute blunt trauma to hypothenar eminence. Middle-aged male laborers, smokers, and dominant hands are affected frequently. Hand pain, discoloration or ulceration of digits, cold intolerance, hypothenar pulsatile mass, hypothenar weakness, and numbness are significant clinical findings. ⋯ She was diagnosed as HHS secondary to intense needlework. A calcium channel blocker and low-dose aspirin were prescribed to her, and avoidance of hand traumas was suggested. These interventions relieved digital ischemia symptoms on her hand.

Early identification of peripheral vascular injuries is crucial to prevent acute limb ischemia and amputation. We sought to identify predictors of vascular injury in patients with blunt lower extremity fractures. ⋯ Open tibia-fibula fractures particularly those involving a mid-shaft location are independent predictors of vascular injuries in patients with blunt lower extremity fracture. These findings may help identify patients requiring diagnostic and surgical intervention.
