Case Reports
Transaortic stent grafting of a Kommerell diverticulum arising from a right-sided aortic arch.
In this article, we report the case of a 68-year-old woman who presented with shortness of breath. Respiratory function tests showed a slightly obstructive physiology. Computed tomography (CT) results revealed an aberrant left subclavian artery and a Kommerell diverticulum arising from a right-sided aortic arch that was compressing the trachea and the surrounding tissues. ⋯ Postoperative CT showed complete exclusion of the Kommerell diverticulum without an endoleak. The patient's breathing difficulty was resolved, and she was discharged uneventfully. This procedure should be considered as an alternative strategy for exclusion of Kommerell diverticulum.

To effectively isolate thoracic aortic lesions in thoracic endovascular aortic repair (TEVAR), an adequate proximal landing zone length is required. The left subclavian artery (LSCA) and other branches of the aortic arch commonly impose limitations on proximal landing zone length, restricting the use of TEVAR. In this study, we investigated the outcomes of LSCA coverage during TEVAR. ⋯ Intentional coverage of the LSCA to obtain an adequate proximal landing zone for TEVAR can be a treatment option for thoracic aortic lesions, although some patients experienced mil complications.

We report the case of an acute ischemia of the superior mesenteric artery (SMA) after endovascular fenestration of a complicated acute type B aortic dissection. An initial attempt for endovascular revascularization of the SMA failed, and an ascending aorto-superior mesenteric artery bypass was urgently performed to salvage the small bowel. Surgery of patients in these specific settings is more complex because an adequate, more distal inflow vessel is often not present due to the dissected aorta and iliac arteries. This surgical option could be lifesaving and should be part of the vascular surgeon's armamentarium.

Surgical intervention for neurogenic thoracic outlet syndrome (NTOS) is not always successful. Treatment plans can be difficult in patients presenting with recurrent symptoms. The purpose of this study was to evaluate outcomes of this patient subset, who underwent operative intervention to remove a remaining or residual first rib because of recurrent thoracic outlet syndrome (TOS)-related symptoms. ⋯ Patients who present with recurrent symptoms of TOS need to be evaluated for remaining or residual first ribs. Operative intervention to remove the remaining or residual first rib in this patient subset is beneficial and can be performed without significant morbidity. Patients undergoing procedures for TOS support our procedure of complete first rib removal at the time of the initial operation to prevent recurrence of symptoms.

Recurrent symptoms of thoracic outlet syndrome (TOS) after first rib resection have varying etiologies. Regrowth of a first rib is a rare event. Recurrent symptoms in the presence of a regrown rib strongly suggest a causal relationship. We report our experience with recurrent symptoms of TOS and regrown first ribs. ⋯ Regrowth of the first rib is a rare event. There is a concordance between a regrown rib and TOS symptoms. Patients presenting with recurrent TOS symptoms and a regrown first rib have a high probability of improvement with resection of the regrown rib.
