Tapered reinforced graft and vein cuff in the distal anastomosis as adjunct strategies for infrapopliteal prosthetic bypass graft in chronic limb-threatening ischemia: A case report.

The great saphenous vein is the optimal conduit for infrapopliteal bypass surgery in chronic limb-threatening ischemia. A prosthetic bypass graft is an acceptable option when the autologous vein is unavailable and the anatomy is not favorable for endovascular therapy. However, the low patency rate of prosthetic grafts calls for adjunct strategies to improve the outcomes.

Superficial Femoral Artery in-Stent Restenosis Treated with Paclitaxel-Coated Balloon Angioplasty - Results of Three-Year Follow-Up.

Background: In-stent restenosis remains a common and important complication after endovascular treatment of superficial femoral artery peripheral artery disease. It occurs in 14 to 35% of cases in 1 year and there is still no efficient treatment for this condition. Paclitaxel-coated balloons have shown promising results.

Short-Term Outcomes of Transfemoral Carotid Artery Stenting and Carotid Endarterectomy in Symptomatic Patients: Data from a Multicentric Prospective Registry in Brazil.

Background: Transfemoral carotid artery stenting (TF-CAS) and carotid endarterectomy (CEA) are alternative strategies for stroke prevention in patients with atherosclerotic carotid disease. Because their main objective is to prevent future ischemic events, regular reassessment of the outcomes is mandatory for providing the best therapy. The purpose of this study was to describe the practice and the outcomes of TF-CAS and CEA in symptomatic patients in public university hospitals in Brazil, using data from a prospective multicentric registry.

Inpatient consultations with the vascular and endovascular surgery team at an academic tertiary hospital.

Background: Inpatient consultations are a fundamental component of practice in tertiary care centers. However, such consultations demand resources, generating a significant workload.

Objectives: To investigate the profile of inpatient consultations requested by other specialties and provided by the Vascular and Endovascular Surgery team at an academic tertiary hospital.

Surgical treatment of cervical rib-associated arterial thoracic outlet syndrome.

The arterial form of thoracic outlet syndrome is rare and is associated with anatomic anomalies, generally a cervical rib. It has a varied range of manifestations. The aim of this article is to describe two cases with different clinical presentations: microembolization and aneurysm.

Contemporary Management of Arterial Thoracic Outlet Syndrome.

Background: Arterial thoracic outlet syndrome (aTOS) is characterized by compression of the subclavian artery as it exits the thoracic girdle. Chronic and repetitive compression leads to several degrees of arterial wall damage. The treatment is varied and depends on the presentation severity.

Endovascular repair of a ruptured abdominal aortic aneurysm after endovascular aneurysm repair due type IB endoleak associated with a late fistula between the abdominal aorta and a retroaortic left renal vein.

A ruptured abdominal aortic aneurysm after endovascular aneurysm repair with an arteriovenous fistula between the aneurysm sac and a retroaortic left renal vein is an extremely rare complication. This case describes an 81-year-old man who developed an aorto-left renal vein fistula owing to a type IB endoleak 2 years after endovascular aneurysm exclusion. The leak was repaired with a left endograft limb extension.

Colonoscopy complications: experience with 8968 consecutive patients in a single institution.

Objective: to evaluate the incidence, epidemiological characteristics, diagnosis and evolution of patients who returned to the emergency care units of the Albert Einstein Hospital in São Paulo/SP with signs and symptoms suggestive of colonoscopy complications up to 30 days after the procedure.

Methods: we conducted a retrospective, uni-institutional study of patients submitted to colonoscopy in 2014 who returned to the Emergency department (ED) within 30 days after the procedure.

Results: 8968 patients underwent colonoscopies, 95 (1.

Effect of graduated compression stockings on venous lower limb hemodynamics in healthy amateur runners.

Objective: The objective of this study was to analyze the effect of graduated compression stockings (GCS) on venous lower limb hemodynamics in healthy amateur runners.

Methods: Ten runners were evaluated during rest and after a 10-km run without and with knee-high GCS of 20 to 30 mm Hg. Air plethysmography evaluated venous filling index (VFI), ejection fraction, and residual volume fraction (RVF) in both limbs.

Endovascular Repair of Infrarenal Abdominal Aortic Aneurysm Results in Higher Hospital Expenses than Open Surgical Repair: Evidence from a Tertiary Hospital in Brazil.

Background: Endovascular aneurysm repair (EVAR) has become the preferred approach for the treatment of infrarenal abdominal aortic aneurysm (IRAAA) in detriment of open surgical repair (OSR). EVAR results in lower mortality rates within 30 days, but rates tend to be the same after longer periods. Moreover, reduced use of hospital resources with EVAR does not necessarily offset the costs of the endoprosthesis.
