AI Article Synopsis
- Arterial cannulation in the right axillary artery is a common method for treating acute aortic dissection, but in this case, an aberrant right subclavian artery was missed before surgery.
- During the surgery, an unexpected collapse in blood pressure occurred when the cannulation was attempted, which was quickly remedied by shifting to femoral perfusion.
- Post-surgery imaging showed that the right aberrant subclavian artery was well-perfused, highlighting the need for surgeons to consider potential aortic arch anomalies when performing this procedure.
Article Abstract
Arterial cannulation into the right axillary artery is a commonly adopted perfusion strategy in the treatment of acute aortic dissection. Here we describe our experience of accidentally cannulating the axillary artery in a case of acute aortic dissection with an aberrant right subclavian artery, which was missed preoperatively because its proximal segment was malperfused by the dissection and thereby not enhanced. The rapid hemodynamics collapse at the start of the bypass was reversed by prompt switching to femoral perfusion. Postoperative follow-up computed tomographic angiography revealed a well-perfused right aberrant subclavian artery. Surgeons should be aware of an aortic arch anomaly whenever performing an axillary artery cannulation.

Rare bilateral vascular variations of the upper limb: a cadaveric case study.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

In this study, we developed and validated a hybrid quantitative model for simulating upper extremity junctional hemorrhage in swine, aiming to advance the development of pre-hospital hemostatic products. Utilizing 12 healthy 8-month-old male Yorkshire swine, we demonstrated the feasibility of a swine axillary artery injury model for evaluating hemostatic efficacy. Animals were divided into three groups to undergo volume-controlled hemorrhage (VCH), mimicking Class I-III hemorrhagic shock by withdrawing blood at different rates.

Takayasu arteritis (TA) is a form of large vessel vasculitis that may lead to fibrosis, stenosis, or aneurysm formation of vessels. Its presentation varies depending on the arterial beds involved. We report 3 cases out of around 150 cases of TA with rare initial presentations of brachial plexopathy caused by an axillary artery aneurysm, complicated type A intramural hematoma, and renal artery aneurysms along with abdominothoracic TA presenting as a pulsatile abdominal mass.

Porcelain aorta describes circumferential calcification in the ascending aorta that may extend through the aortic arch. This is commonly observed in patients with a history of mediastinal radiation, end-stage renal disease, or chronic vascular inflammation. Mediastinal radiation has been shown to cause intimal and medial calcification of the aorta, as well as diastolic myocardial dysfunction, valvular disease, and coronary artery disease.

Objectives: To determine if the subtype of vascular ultrasound (US) presentation is associated with different types of ischaemic complications (IC) in giant cell arteritis (GCA).
Methods: Retrospective observational analysis of GCA clinically confirmed patients referred to US fast-track clinics at two centres. All patients underwent baseline US of cranial and extracranial arteries (carotid, subclavian and axillary).
