Endovascular treatment of an iatrogenic right subclavian artery pseudoaneurysm associated with an arteriovenous fistula.

This report describes the case of a frail 36-year-old patient who underwent an endovascular treatment of a right subclavian artery pseudoaneurysm (SAP) associated with an arteriovenous fistula secondary to a traumatic central venous catheter insertion. The deployment of a covered stent from the innominate to the right common carotid artery combined with coiling of the SAP and the internal mammary artery was performed. Two additional covered stents were deployed from the vertebral artery to the distal subclavian artery to preserve right upper extremity circulation. This case highlights the feasibility of an endovascular treatment of a complex SAP in a candidate unsuitable for open surgery.

Closure Device Migration: An Unusual Cause of Acute Limb Ischaemia Following a Simple Endovascular Procedure.

Introduction: Acute limb ischaemia resulting from foreign body embolisation is an infrequent yet critical complication associated with vascular closure devices (VCDs). Despite the widespread use of VCDs, rare complications such as fragment emboli pose unique challenges, necessitating heightened clinical awareness. This case report presents a case of acute limb ischaemia caused by a VCD malfunction following an endovascular procedure. Report: A 70 year old male who was diagnosed with a severe claudication of the lower extremity (Rutherford III) due to right common iliac stenosis, underwent angioplasty using a FemoSeal (Terumo Ltd., Surrey, UK) to close the right femoral artery access. Two weeks later, the patient presented with acute lower limb ischaemia due to a right popliteal-tibial occlusion. Emergency surgical thrombo-embolectomy was successfully performed from a medial popliteal approach, and the thrombus, which contained a polymer disc from the VCD at its distal end, was completely removed. Discussion: Despite VCDs being proven safe and efficient, rare complications such as fragment emboli can occur, and physicians should be aware of the possible delayed onset of symptoms. Moreover, the radiolucent nature of the polymer disc in a FemoSeal complicates diagnostic imaging. While endovascular approaches exist, open surgery is a safe and effective strategy for retrieving fragments and treating the patient in acute limb ischaemia cases. Conclusion: Physicians should remain vigilant for embolic risks associated with vascular closure devices, even with suitable anatomy and following guidelines, especially considering the trend toward early ambulation and discharge.

Inverted Ovation iX Limb to Treat an Isolated Common Iliac Artery Aneurysm.

In recent years, endovascular aneurysm repair has become the predominant method of managing abdominal aortic and common iliac artery aneurysms. Off-label use of different endovascular devices has allowed them to remain a viable option in many cases of atypical anatomy. Some studies have reported the use of iliac devices in an upside-down configuration when the common iliac artery aneurysm has a reverse-tapered morphology. However, the use of the Ovation iX (Endologix) limb in an upside-down configuration has not yet been reported. This limb offers a 14 mm distal end when inverted and offers good patency in the tortuous iliac morphology. This case report describes and illustrates the precise deployment of an inverted Ovation iX limb to treat an isolated common iliac artery aneurysm.

A mycotic aneurysm of a jejunal branch treated by aneurysmectomy without bowel resection.

Jejunal artery pseudoaneurysms are extremely rare, accounting for <1% of all visceral artery pseudoaneurysms. Fewer than 50 cases were reported in literature during the previous century. This case report describes the case of a 72-year-old man who underwent aneurysmectomy to treat a 21-mm mycotic jejunal artery pseudoaneurysm found in the setting of endocarditis. This pseudoaneurysm was treated with laparotomy, and gentle dissection of the tissues surrounding the pseudoaneurysm was performed before ligation and resection. This allowed for vascular collateral branch preservation, which, thus, avoided concomitant bowel resection. This report highlights the feasibility of this technique.
