Double Aortic Arch

During embryogenesis, the aortic sac is connected to paired dorsal aortae via six symmetrical aortic (Ao) arches, which give rise to major vascular structures. For example, the right and left common carotid arteries originate...

Aortic Aneurysm Fat Stranding On CT

As a cardiac anesthesiologist and cardiovascular intensivist, I care for many patients with aortic aneurysms in the perioperative setting. Contrast-enhanced CT imaging is traditionally utilized to assess the location and size of the aneurysm...

Types Of Endoleaks

Endovascular aneurysm repair (EVAR) offers many patients a minimally invasive option to address vascular pathologies like aortic aneurysm. By deploying a fabric-covered stent within the aneurysm, blood is rerouted through this conduit thereby excluding...

Zones Of The Aorta

As a cardiothoracic anesthesiologist and intensivist, I care for many patients in the OR and ICU who have aortic aneurysms or dissections undergoing open/endovascular repair. It's important to localize the aortic pathology to determine...

TEVAR For Aorto-Esophageal Fistula

Aorta-esophageal fistula is an abnormal communication between the aorta and esophagus leading to life-threatening exsanguination via the GI tract. This can be caused by procedures (e.g., weeks following cardiac arrhythmia ablation), malignancy, foreign body,...

Type A Dissection

Acute ascending aortic dissection (type A) is a true surgical emergency. Arterial walls are comprised of the intima (innermost layer), media, and adventitia (outermost layer). In a dissection, an intimal tear creates a plane...

Superior Vena Cava (SVC) Syndrome

Superior vena cava (SVC) syndrome is characterized by facial plethora, upper body venous engorgement, chest pain, soft tissue swelling, dyspnea, and even neurologic changes. Anything that impairs SVC drainage by intrinsic obstruction (thrombosis, anatomic...

Lumbar Drain

Lumbar drains are a mainstay for spinal cord protection when patients undergo operations like thoracoabdominal aortic aneurysm (TAAA) repairs and thoracic endovascular aortic repairs (TEVAR) with subclavian artery debranching. Why? Because the anterior spinal...
