AI Article Synopsis
- The authors describe their experience with intraarterial digital subtraction angiography (DSA) for outpatient treatment of vascular diseases, using brachial artery catheterization in 120 patients.
- Despite the complexity of procedures, the success rate was high, with most catheter placements performed smoothly in both cerebral and lower limb examinations.
- Complications were minimal, including a few cases of ecchymosis and small hematomas, leading the authors to recommend transbrachial DSA as a viable alternative to intravenous DSA for outpatient care.
Article Abstract
The authors report their experience with intraarterial digital subtraction angiography (DSA) performed on outpatients via brachial artery catheterization. A total of 120 outpatients were studied for cerebral and lower limbs vascular diseases. Transbrachial catheterization was performed with 5F or, preferably, with 4F angiographic catheters. Success rate was high and the transbrachial approach was always easy. In the course of cerebral examination (18/120 cases) the catheter was always easily positioned in the ascending thoracic aorta, through right transbrachial approach. In the course of abdominal aorta and lower extremities examination (102/120 cases), the ideal catheter positioning--in the descending aorta--was performed in 95/102 cases, by left transbrachial approach, while in 7/102 patients the catheter was placed in the ascending aorta. The complication rate was low: 7/120 ecchymosis, 4/120 small hematomas spontaneously resorbed, and 2/120 transient spasms of brachial artery. The authors suggest trasbrachial intraarterial DSA as an alternative to intravenous DSA in outpatients.

Clinical Outcomes of Shifting from Transfemoral-First to Transradial-First Approach in Carotid Artery Stenting: A Retrospective Two-Timeframe Comparison at a Single Center.

Carotid artery stenting (CAS) has traditionally been performed using the transfemoral approach (TFA). Recently, the transradial approach (TRA) has gained attention for its lower invasiveness and reduced complication risk. This study compares outcomes between two access strategy timeframes, TFA-first and TRA-first, to evaluate how this shift influences outcomes in a real-world setting.

Typically, CAS is performed via a transfemoral, transbrachial, or transradial approach. However, direct puncture CAS (DP-CAS) is preferred in cases where conventional access routes are challenging, such as in the presence of cervical vascular tortuosity or thoracic aortic aneurysm.

Background Endovascular aneurysm repair (EVAR) has evolved into treatment of choice for infrarenal abdominal aortic aneurysms (AAA). Type II endoleaks, although frequently benign, can lead to sac enlargement and rupture. Management of these endoleaks by endovascular means can be quite challenging and may require complex techniques and assistance of interventional radiologists, not always available in all vascular units.

Article Synopsis
- The study aimed to compare complication rates at access sites for trans-axillary and trans-brachial approaches using sheath sizes of 6Fr or larger in endovascular interventions.
- A total of 67 cases were reviewed over 18 months, and the main outcome was the occurrence of major site complications within 30 days.
- Results showed no significant difference in complication rates between the trans-axillary (15%) and trans-brachial (17%) groups, indicating that both methods are safe, with trans-axillary being particularly effective for larger sheath sizes.
Turn-Over Technique for Inserting and Stabilizing Guiding Sheath without Straightening It during Carotid Artery Stenting via Trans-Brachial Approach in Cases with Severe Vascular Access Conditions.

Objective: In cases of severe atherosclerosis or tortuous arteries, inserting the guiding sheath into the target vessel is challenging. Here, we present the turn-over technique for inserting and stabilizing the guiding sheath without straightening it during carotid artery stenting (CAS).
Case Presentation: Two patients with severe left internal carotid artery stenosis underwent CAS via the trans-brachial approach.
