Open Aneurysm Repair

The aim is to remove the rupture risk by replacing the aneurysmal segment with a durable synthetic graft sewn to healthy artery. It is used for aneurysms that have reached a treatment threshold, cause symptoms, grow rapidly or are anatomically unsuitable for endovascular repair. The decision weighs rupture risk against the physiological demands of major surgery for that individual.

• Aneurysms at or beyond the agreed treatment threshold
• Symptomatic or rapidly growing aneurysms
• Anatomy unsuitable for endovascular repair
• Sufficient cardiac, respiratory and renal reserve for major surgery

Frailty and organ function are assessed as thoroughly as the aneurysm itself, because they largely determine operative risk. Open repair also remains important when an aneurysm is infected or ruptured, or when long-term durability favours conventional reconstruction.

CT angiography defines the aneurysm and its branch arteries. Heart, lung and kidney function are assessed carefully, because open aortic surgery places significant physiological demands on the body. Blood products and postoperative critical-care support are planned in advance. Bring an accurate list of all medicines and blood thinners to the preoperative consultation; anticoagulation management is planned individually. Prehabilitation, especially stopping smoking, pays dividends in recovery.

Open abdominal aortic repair

The surgeon reaches the aorta through an abdominal or side incision, temporarily clamps the artery and replaces the aneurysmal segment with a synthetic graft. The graft may extend into one or both iliac arteries.

Complex and thoracic repair

Repair involving arteries to the kidneys, bowel or chest may require specialised exposure, organ protection and collaboration with cardiothoracic or other surgical teams.

Why choose open repair over a stent graft?

Open repair does not depend on landing-zone anatomy and rarely needs reintervention once healed, which can make it the better option for younger or anatomically unsuitable patients. The trade-off is a bigger operation and longer recovery.

Patients are monitored initially in intensive or high-dependency care, with attention to breathing, kidney function, bowel recovery, pain and mobility. Hospital stay is usually several days, and recovery at home continues over weeks to months, supported by mobilisation, breathing exercises, nutrition and wound care. Open grafts are durable, but follow-up continues to monitor the rest of the aorta and overall cardiovascular health.

• Bleeding
• Heart or lung complications
• Kidney injury
• Bowel or limb ischaemia
• Wound or graft infection
• Blood clots
• Incisional hernia
• Sexual dysfunction after some abdominal repairs
• Prolonged recovery

Risk varies substantially with aneurysm extent, urgency and general health, and is quantified as far as possible before a decision is made.

Endovascular repair or continued surveillance may be alternatives to open aneurysm surgery. Open repair is often preferred when the anatomy is unsuitable for a secure stent-graft seal, when other aortic branches require reconstruction or when a durable repair is particularly important for a younger, fitter patient.

The operation involves a larger physiological stress than endovascular treatment, so planning includes careful assessment of heart, lung and kidney function, previous abdominal or chest surgery and overall fitness. Patients should understand the expected hospital stay, the likelihood of intensive care, pain management and the gradual return of appetite, strength and normal activity.

Open repair generally requires less device-specific imaging than EVAR, but long-term vascular care remains important because disease can develop elsewhere. The consultation should compare the immediate risks and recovery of open surgery with the surveillance burden and possibility of later reintervention after endovascular repair, allowing the choice to reflect both anatomy and personal priorities.

Yarra Vascular Surgeons provides detailed preoperative assessment and open aortic expertise, planning treatment around aneurysm extent, branch vessels, cardiac and respiratory health and the long-term reliability of the repair.

Open aneurysm repair remains a durable option when anatomy is unsuitable for endovascular treatment or complex reconstruction is required. Sudden severe abdominal or back pain in a person with a known aneurysm is an emergency: call Triple Zero (000).
