Abstract

Purpose:

The aim of this study was to evaluate the technical feasibility and short-time patency rate of iliac side branch devices based on the authors' institution's experience.

Materials And Methods:

Data of 17 patients (all men) with an aortoiliac aneurysm (median age 72.5 years) who underwent endovascular repair between October 2013 and June 2015 (20 months) at our institution was analyzed retrospectively. Primary endpoint was primary technical success, defined as adequate implantation of the iliac branch device with patency of the hypogastric side branch without the need of further re-interventions within 30 days. Mean follow-up was 8.2 ± 5.4 months.

Results:

Eighteen iliac side branch devices were implanted with a branch patency of 100 % and a primary technical success rate of 94.4 % (n = 17). Perioperative 30 days mortality was 0 %. The mean diameter of treated abdominal aorta and common iliac artery was 41 ± 14 and 30 ± 8 mm. In one case partial dislocation of the iliac side branch device occurred due to severe kinking of iliac arteries with development of an iliac endoleak type Ib that had to be treated in a second intervention. Three patients (15 %) showed an endoleak type II from the inferior mesenteric artery without the need of re-intervention. After three months one patient suffered from subtotal thrombotic occlusion of the bridging stent that was successfully resolved through intra-arterial fibrinolytic therapy and additional stent graft implantation.

Conclusion:

Summarized, implantation of iliac side branch devices is a feasible technique with favourable short-term results in patients with aortoiliac aneurysm.

Key Points:

• Implantation of iliac side branch devices is a feasible technique.• Distinguish short-term results of side branch endografting in patients with aortoiliac aneurysm.• Carefully patient selection is necessary to avoid complications and re-interventions.

Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Arteries of Lower Limbs

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Abdominal Aorta

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Anastomoses

Anastomoses

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They...
