RESUMO
OBJECTIVE: Management of penetrating atherosclerotic ulcers (PAU), intramural hematomas (IMH), and acute aortic dissections (AD) of the thoracic aorta remain controversial in the endovascular era. METHODS: Between 2001 and 2007, patients with PAU (13 patients), and/or IMH (7 patients) were treated with thoracic endografts (TEVAR) in the endovascular suite under general anesthesia. Indications for intervention were intractable chest pain, expanding hematoma or contained rupture, or distal malperfusion. End-points were early morbidity and mortality, incidence of endoleak, device-related complications, and secondary interventions. RESULTS: Of the 20 patients with a median age of 67 (25-83), 13 (65%) were men, 2 (10%) had contained aortic rupture, and 10 were symptomatic. One patient had carotid-subclavian bypass debranching before endograft implantation. Ten patients had cerebrospinal fluid drainage. Mean length of aorta treated was 122.1 mm (range 36-300). All endografts were technically successful. Average blood loss was 50 mL. Thirty-day mortality was 0%. Symptoms resolved in all patients; there were no neurologic complications. Average length of stay was 5 days. Mean follow-up was 2.0 years (range 0.1-5.8). All patients remained asymptomatic. Three had early (<180 days) endoleaks: Two type II and 1 type I treated successfully with an additional cuff, which was the only patient requiring reintervention. Two patients had late (>180 days) endoleaks (type 2) observed with no aortic expansion. Two deaths at 5.4 and 5.8 years were due to severe aortic valve stenosis and metastatic lung cancer. CONCLUSION: TEVAR is a feasible option for repair of non-aneurysmal thoracic aortic pathology with resolution of symptoms, no mortality, and no neurologic complications.

BACKGROUND: The predictors of amputation for patients with lower extremity vascular trauma are well described in the literature, but the predictors of amputation in the upper extremity are not so well defined. We hypothesize that the predictors of amputation in the lower extremity are much different when compared with the upper extremity. METHODS: Retrospective chart review of all brachial artery traumatic injuries presenting to a rural-state university trauma center. RESULTS: In a 6-year period, 41 patients presented with brachial artery injuries. Operative management was performed in 38 (93%) patients which included 23 reversed saphenous vein grafts, 13 primary repairs, and 2 synthetic grafts. There were four deaths (9.8%) and four (9.8%) amputations. Comparing the amputation and limb salvage groups, the Injury Severity Score (ISS) was 32 versus 12, whereas the Mangled Extremity Severity Score (MESS) was 7 versus 4.3. Five patients had a MESS score greater than 7; four of whom had an amputation or died. Amputation was performed in only 4 of 23 patients with neurologic deficits. Limb salvage was successful in 24 of 28 patients without a palpable pulse on arrival. CONCLUSIONS: Predictors of amputation in brachial artery injuries differ from lower extremity vascular injuries. Delayed presentation greater than 6 hours, MESS, open fracture, nerve deficits, and diminished capillary refill were not predictive of amputation for patients with brachial artery injuries. These data suggest that the vast majority of upper extremity injuries should have attempted salvage regardless of the severity scoring systems.

OBJECTIVES: Evidence is mounting linking cerebrovascular disease with the development of major depression in the elderly. Lesions in both white and gray matter have been associated with geriatric depression. In addition, the literature on poststroke depression suggests that left-sided lesions are associated with depression. We sought to examine the severity and location of white- and gray-matter lesions in a group of elderly depressives and nondepressed control subjects. METHOD: 115 depressed patients (69 with late onset, 46 with early onset) and 37 controls, all over age 45, received magnetic resonance imaging (MRI). Semiquantitative severity ratings and quantitative measurements of number and size of MRI hyperintensities were obtained, and groups were compared using Cochran-Mantel-Haenszel (CMH) analyses and repeated-measures analyses of covariance adjusting for age. RESULTS: Late-onset depressed patients had more severe hyperintensity ratings in deep white matter than early-onset patients and controls. Late- and early-onset patients had more severe subcortical gray-matter hyperintensities (particularly in the putamen) compared with controls. Left-sided white-matter lesions were significantly associated with older age of depression onset, whereas right-anterior white matter and left-subcortical lesions (particularly in the putamen) were associated with melancholia in the depressed group. CONCLUSION: These findings extend previous reports of an association between cerebrovascular disease and depression, as well as recent studies showing lateralized lesion involvement in geriatric depression. Such vascular pathology may disrupt neural pathways involved in affective processing and the maintenance of a normal mood and psychomotor state.
