Objective: The integrity of the plantar flap is important for transmetatarsal amputation (TMA) classic closure. However, in ischemic wounds, the plantar flap can be compromised, making the TMA coverage difficult. The aim of this study was to compare the outcomes of rotational vs long plantar flaps for transmetatarsal amputation closure in patients with dysvascular partial foot amputations.

Article Synopsis
  • A study on 476 hospitalized patients with chronic limb-threatening ischemia (CLTI) aimed to explore how various atherosclerosis risk factors (like age, gender, diabetes, smoking, and hypertension) affect the anatomical distribution of Peripheral Arterial Disease (PAD).
  • Results revealed that gender, smoking, and diabetes significantly influence the location of PAD, with women more likely to have femoropopliteal disease and smokers at a higher risk for aortoiliac disease.
  • Diabetic patients tend to have isolated infrapopliteal occlusive disease, demonstrating the need to consider these risk factors for better PAD management.

Objective:  This study aims to describe our technique and early experience with physician-modified endovascular grafts (PMEGs) for aortic arch diseases in zone 2. We used a total endovascular technique based on a single fenestrated endograft to preserve left subclavian artery (LSA) patency.

Methods:  From December 2019 to August 2020, six consecutive patients with a variety of thoracic aortic diseases were treated with handmade fenestrated thoracic aortic grafts: four aortic dissections, one penetrating aortic ulcer, and one intramural hematoma.

Purpose: The purpose of this study was to present a new technique for endovascular aortic arch repair for 1, 2, or 3 vessels using preloaded wires and precannulated target vessels without wire wrapping.

Technique: This technique uses a prototype catheter with 2 parallel lumens to position through-and-through guidewires in the supra-aortic branches and an extra-stiff guidewire in the ascending aorta with no wrapping. This allows the introduction and advancement of the device with the already precannulated target vessels.

Endovascular techniques have proven useful in aortic arch management because they allow less invasive treatment and potentially faster recovery. We present the case of a 66-year-old woman with a 2-month history of precordial pain. Imaging studies revealed a saccular aortic arch aneurysm in the anterior portion of the arch.

Background: Deep infections of the extremities are a challenge that threaten limb salvage.

Objectives: To investigate whether the results of bone and deep tissue cultures from patients with trophic limb ulcers coincide.

Methods: A retrospective study was conducted with data from 54 patients with deep trophic limb ulcers admitted to the Complexo Hospitalar Universitário Professor Edgard Santos, Salvador (BA), Brazil.

Atherosclerotic disease of the extracranial carotid arteries can cause complications with high morbidity and mortality rates. The contrast imaging examinations used in preoperative evaluation are associated with complications such as parotitis, in addition to well-known allergic reactions and renal dysfunction. A high carotid bifurcation or atherosclerotic disease that extends distally are often limiting factors for conventional surgical treatment.

Objective: The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach.

Methods: Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded.

The peroneal artery is an important outflow vessel for lower limb revascularization and limb salvage. This vessel is commonly reached using a medial, posterior, or lateral approach with resection of the fibula. We present a technique of lateral approach to the peroneal artery without fibular resection.

Endovascular techniques have shown to be useful in the management of vascular injuries because they transform a complex and potentially dangerous procedure into a safe one. We present the case of a 39-year-old man with congestive heart failure and abdominal bruit 11 years after an abdominal gunshot wound. Imaging studies revealed an arteriovenous fistula involving the left iliac artery bifurcation, and an iliac branch device was used to treat it.
