Methods: Between October 2015 and November 2020, 10 patients underwent VATS anatomical lobectomy and en bloc chest wall and spinal resection through a limited posterior midline incision as a single operation for T4 (vertebral involvement) lung cancer. Nine patients had Pancoast syndrome without vascular involvement and 1 patient had NSCLC of the right lower lobe with invasion of T9 and T10.

Partial Vertebrectomies without Instrumented Stabilization During En Bloc Resection of Primary Bronchogenic Carcinomas Invading the Spine: Feasibility Study and Results on Spine Balance.

Objective: It is unknown whether spinal instrumentation is required to prevent deformity after partial vertebrectomy in the treatment of primary bronchogenic carcinomas invading the spine (PBCIS). In this study, we focus on the postoperative spine deformity in patients who underwent operation for partial vertebrectomies without instrumentation during en bloc PBCIS resection. Our objective was to determine whether deformity depends on the type of vertebral resection and if any vertebral resection threshold can be observed to justify additional spinal instrumentation.

Staged Hybrid Repair to Reduce the Risk of Spinal Cord Ischemia After Extensive Thoracic Aortic Aneurysm Repair.

We hypothesized that staged repair of extensive thoracic aneurysms might mitigate the incidence and severity of spinal ischemia by facilitating structural remodeling of the spinal cord vasculature. Staged hybrid repair (in two or three stages) was undertaken in 7 patients with extensive thoracic aortic aneurysms. The 30-day mortality and spinal ischemia rates were 0%.

Hybrid Aortic Repair of Dissecting Aortic Arch Aneurysm after Surgical Treatment of Acute Type A Dissection.

Background: The aim of this study was to evaluate the short-term and midterm results of hybrid repair of dissecting aortic arch aneurysms subsequent to surgical treatment of acute type A dissections.

Methods: Between 2003 and 2014, 7 consecutive patients, previously operated for acute type A dissection, underwent hybrid repair of their aortic arch for a dissecting aortic arch aneurysm (6 men, mean age 62 ± 11 years). Aneurysm formation requiring treatment in these aortic arches was observed from 2 to 20 years after the initial aortic dissection repair.

Saccular Thoracoabdominal Aneurysms in Systemic Lupus Erythematosus.

Aortic aneurysm is a rare but a serious complication of systemic lupus erythematosus. We report the case of a 59-year-old man with systemic lupus erythematosus disease who presented with symptomatic saccular thoracoabdominal aneurysms. The 2 aneurysms were resected and 2 silver-coated tube grafts were interposed.

Minimum 10-year follow-up of endovascular repair for acute traumatic transection of the thoracic aorta.

Objective: Thoracic endovascular aortic repair (TEVAR) for traumatic rupture of the descending thoracic aorta seems, in the short term, to be associated with better outcomes than open repair, but long-term data are lacking.

Methods: A review was conducted of a prospectively maintained database of patients who underwent TEVAR for traumatic rupture of the descending thoracic aorta in our unit, with a minimum 10-year follow-up. Follow-up computed tomography scans were performed at 1 week, 3 and 6 months, and annually thereafter.

Experimental evaluation of complete endovascular arch reconstruction by in situ retrograde fenestration.

Background: The aim of this experimental study was to assess the feasibility of complete endovascular arch reconstruction by in situ retrograde fenestration and to investigate the impact of stent-graft material on stent-graft fenestrations.

Methods: The experiments were performed using 8 cadaveric human thoracic aortas (aortic arch) using 2 different stent-graft types: woven polyester (Valiant Captivia; Medtronic Vascular, Santa Rosa, CA) and expanded polytetrafluoroethylene (conformable [C]-TAG; W.L.

Combined endovascular and surgical approach for aortobronchial fistula.

Objective: The perioperative outcomes of the endovascular approach to aortobronchial fistula have been favorable. However, it is uncertain whether thoracic endovascular aneurysm repair (TEVAR) alone provides a complete and durable cure for an aortobronchial fistula. TEVAR does nothing to address the issue of the defect in the respiratory tract, leaving the patient at risk of aortobronchial fistula recurrence and/or stent graft infection.

Local carotid atherosclerotic plaque proteins for the identification of circulating biomarkers in coronary patients.

Objective: To identify circulating biomarkers that originate from atherosclerotic vulnerable plaques and that could predict future cardiovascular events.

Methods: After a protein enrichment step (combinatorial peptide ligand library approach), we performed a two-dimensional electrophoresis comparative analysis on human carotid plaque protein extracts (fibrotic and hemorrhagic atherosclerotic plaques). In silico analysis of the biological processes was applied on proteomic data.

Assessment of abdominal branch vessel patency after bare-metal stenting of the thoracoabdominal aorta in a human ex vivo model of acute type B aortic dissection.

Objective: The purpose of this study was to assess the efficiency of bare-metal stenting of the thoracoabdominal aorta in a human ex vivo model of acute type B aortic dissection and the impact of this approach on the patency of the visceral and renal arteries.

Methods: Fifteen human cadaveric aortas were harvested. Type B aortic dissections were surgically initiated 2 cm below the left subclavian artery.

Impact of preoperative marking coils on surgical and pathologic management of impalpable lung nodules.

Background: The management of occult lung lesions, particularly subsolid opacities, is a new challenge because they are difficult to localize during surgery and the number of lesions detected by computed tomography (CT) is increasing.

Methods: Between February 2008 and December 2011, preoperative CT-guided marking with coils was systematically carried out to localize presumed impalpable nodules before video-assisted thoracoscopic surgery (VATS). The procedure feasibility, reliability, and safety as well as its impact on the resection volume and on the pathologic examination strategy were examined.

Objective: This study assessed predictive factors for reintervention after thoracic endovascular aortic repair (TEVAR) for complicated aortic dissection (C-AD).

Methods: An institutional review of consecutive TEVAR for C-AD was performed.

Results: Between 2000 and 2011, 41 patients underwent TEVAR for a C-AD involving the descending thoracic aorta.

Human ex-vivo model of Stanford type B aortic dissection.

Objective: To report a new human ex vivo model of type B aortic dissection (TBAD) and to assess if the locations of the primary entry tear determine the patterns of dissection propagation.

Methods: Twenty fresh human aortas were harvested. TBADs were surgically initiated 2 cm below the left subclavian artery at four different locations (lateral, n = 5; medial, n = 5; anterior, n = 5; posterior, n = 5).

Heparin-induced thrombocytopenia with abdominal aortic stent-graft acute thrombosis.

We report a case of heparin-induced thrombocytopenia in a patient on low molecular weight heparin bridge therapy who developed acute abdominal aortic stent-graft thrombosis 1 week after uncomplicated endovascular abdominal aortic aneurysm repair. The diagnosis was confirmed by a computed tomographic scan of the abdomen. The patient was successfully treated by conversion to open repair.

Improvement in conformability of the latest generation of thoracic stent grafts.

Objective: Poor aortic arch apposition increases the risk of technical failure after thoracic endovascular repair. The aim of this study was to assess the conformability of the latest generation of thoracic stent grafts in relation to the degree of device oversizing and aortic arch angulation.

Methods: A benchtop pulsatile flow model was designed to test stent graft anchorage in a 2-cm-long proximal landing zone at varying landing zone angles (from 140° down to 70°) and stent graft oversizing (12%-28%).

Endovascular repair of a left common carotid pseudoaneurysm associated with a jugular-carotid fistula after gunshot wound to the neck.

The management of traumatic injury of the common carotid artery has traditionally required a conventional surgical intervention, which is associated with a high mortality rate. Endovascular procedures might offer a less invasive alternative to treat these injuries, with a lower rate of mortality and morbidity. We report the case of a 30-year-old man who presented after penetrating injury due to a low-velocity gunshot wound to the neck.
