We report a case of atypical aortic coarctation with severe calcification of the proximal aorta treated by a new extra-anatomical bypass. This 58-year-old woman with coarctation of the infrarenal aorta had thick circular calcifications of the thoracic aorta and stenosis of the subclavian arteries. To control the progressive claudication, we performed a bypass with an externally supported PTFE graft 6mm in diameter between the right renal artery and the right common iliac artery. Postoperative ankle pressure rose to 84 mmHg (right) and 89 mmHg (left) from zero, and she could walk without pain. Renal function was preserved. Using the proximal anastomosis from the non-diseased aortic branch to avoid the calcified aorta, reno-iliac arterial bypass is a useful alternative for control of ischemic lower limbs.

Para-Anastomotic Pseudoaneurysms as a Long-Term Complication After Surgical Treatment of Peripheral Artery Disease: Clinical Characteristics and Surgical Treatment.

Peripheral arterial disease (PAD) is becoming an increasingly prevalent clinical issue, leading to a growing number of patients requiring surgical interventions. Consequently, there is an increasing occurrence of para-anastomotic aneurysms as late complications following primary treatment for PAD. These aneurysms typically arise at the sites of graft implantation and necessitate individualized management strategies based on factors such as location, size, and the patient's overall condition.

We present a case of bilateral lower limb ischemia caused by endograft collapse due to type B acute aortic dissection (TBAD).

Objective: Central vein occlusion (CVO) is a significant complication in patients undergoing chronic hemodialysis, often leading to dialysis inefficacy, disabling symptoms, and, most critically, major risk of access failure. Although stenting has been proposed as a technique to maintain vascular access patency following the recanalization of occluded central veins, the data supporting its long-term efficacy remains limited. This study aims to evaluate the long-term effectiveness of stenting occluded superior vena cava (SVC) and/or brachiocephalic veins to preserve vascular access patency, ensure continued dialysis efficacy, and relieve SVC syndrome.

Article Synopsis
- Anastomotic pseudoaneurysms of interposition vein grafts are rare but serious complications in vascular surgery, particularly concerning the carotid arteries, requiring urgent intervention to avoid critical issues like rupture and thromboembolism.
- A case report details a 49-year-old male who developed a false aneurysm after a carotid surgery complication and successfully underwent open surgical repair involving the removal of the affected graft and reconstruction using a vein graft from the subclavian artery.
- The conclusion emphasizes that while endovascular techniques exist, open surgical repair remains the standard treatment for these pseudoaneurysms due to its ability to effectively address infection and ensure better long-term outcomes, suggesting that further research should continue to refine surgical strategies.
Midterm Morphological Change of Kommerell's Diverticulum after Hybrid Thoracic Endovascular Aortic Repair.

Department of Cardiovascular Surgery, Osaka University Graduate School of Medicine, Osaka, Japan.
Background: Kommerell's diverticulum (KD) is associated with a high incidence of right-sided aortic arch (RAA). Hybrid thoracic endovascular aortic repair (TEVAR) is an effective and less invasive alternative to open repair. However, the long-term results regarding KD diameter regression or symptom improvement remain inadequately described.
