Twelve tight stenoses (9 of the subclavian artery, 1 of the axillary artery and 2 of the brachio-cephalic artery) were dilated with immediate satisfactory results in all cases. Only one complication (regressive lesion of the median nerve) was recorded. Eight patients were followed-up for a mean period of 13 months: all were symptom-free, and digital angiography by the intravenous route showed a stable image of patency. From a review of published dilatations of the subclavian artery it appeared that the method is 95% effective, that its mortality is nil and that no complication, notably embolism, has been reported. In view of the risks involved in surgical procedures and of the advantages of percutaneous transluminal angioplasty, at least in theory, this technique seems to be a suitable alternative to surgery in stenoses of the subclavian arteries.

Takayasu arteritis (TA), a rare large-vessel vasculitis, primarily affects women of childbearing age, causing granulomatous inflammation in the aorta and its major branches. This inflammation can lead to stenosis, aneurysms, or occlusion, with the abdominal aorta, subclavian, and brachial arteries commonly involved. We present the case of a 26-year-old female with TA with a rare involvement of the superior mesenteric artery (SMA).

Background: Subclavian artery stenosis is generally screened by a left-right brachial systolic blood pressure difference. However, subclavian artery stenoses are often underdiagnosed due to marginally identified symptoms. In dialysis patients, a relative or absolute contradiction of measuring blood pressure in shunt brachial artery may further limit the disease screening.

Article Synopsis
- * The standard transfemoral approach was unsuitable due to severe calcification and anatomical complications, leading to the decision to use the carotid artery instead.
- * Post-surgery outcomes were positive, with no major complications like cerebral infarction and improvement in the patient's dialysis-related hypotension, suggesting this approach can be a safe alternative despite some risks.
In situ needle fenestration for aortic arch conditions during thoracic endovascular aortic repair.

Department of Cardiovascular Surgery, the First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing City, Jiangsu Province, 210029, China.
Article Synopsis
- The study evaluated the effectiveness of the in situ needle fenestration (ISNF) technique in thoracic endovascular aortic repair (TEVAR) for patients with conditions affecting the aortic arch, involving 115 patients treated from January 2018 to December 2021.
- The results showed a 100% technical success rate, with 30-day and overall mortality rates of 3.5% and 8.7%, respectively, while complications included retrograde dissection, strokes, and an endoleak.
- The authors concluded that the mid-term outcomes of the ISNF technique are promising but emphasized the need for long-term follow-up and improvement of fenestration devices.
Percutaneous balloon venoplasty for symptomatic lead-related venous stenosis.

Article Synopsis
- Lead-related venous stenosis (LRVS), often diagnosed incidentally, can cause symptoms like swelling and discomfort in patients with transvenous leads, although actual symptomatic cases are rarer.
- A study at the Hospital of the University of Pennsylvania analyzed 18 patients with symptomatic LRVS who did not respond to anticoagulation and underwent balloon venoplasty, finding that a significant majority (72%) experienced complete symptom relief post-procedure.
- The study concluded that while balloon venoplasty is generally safe and effective, timely intervention is crucial, especially as treatment becomes less effective when secondary lymphedema is present.
