Thoracic Aneurysm - Nursing Case Study

Pathophysiology

• Primary mechanism: Degeneration of the aortic wall due to loss of elastic fibers and smooth muscle cells, often linked to conditions like hypertension and atherosclerosis, weakens the wall, leading to dilation and aneurysm formation.

• Secondary mechanism: Inflammation plays a critical role, where infiltrating immune cells release enzymes that degrade structural proteins in the aortic wall, further compromising its integrity and contributing to aneurysm expansion.

• Key complication: Risk of rupture increases as the aneurysm enlarges, leading to potentially fatal hemorrhage due to the high-pressure blood flow in the thoracic aorta if not managed timely.

Section 1

New Diagnostic Results:

The patient underwent a CT angiography, which revealed a thoracic aortic aneurysm measuring 5.5 cm in diameter, with evidence of mural thrombus. The aneurysm's size and the presence of thrombus are concerning, as they significantly increase the risk of rupture and embolic complications. Additionally, lab results show elevated inflammatory markers, including a C-reactive protein (CRP) level of 15 mg/L, suggestive of ongoing inflammation around the aneurysm. The patient's lipid profile indicates elevated LDL cholesterol at 145 mg/dL, despite atorvastatin therapy, highlighting the need for more aggressive management of hyperlipidemia to slow the progression of atherosclerosis.

In light of these findings, the healthcare team discusses the necessity of surgical intervention, given the size of the aneurysm and the patient's symptomatology. However, the patient's recent unstable blood pressure readings, persistent hypertension, and underlying health conditions such as type 2 diabetes complicate the decision-making process. The team considers optimizing medical management, including increasing the dosage of antihypertensive medication and adding an anti-inflammatory agent to address the inflammatory component. The patient is also counseled about lifestyle modifications, including dietary changes and smoking cessation, which are crucial in managing his cardiovascular risk factors.

As the team deliberates the next steps, the patient begins to exhibit intermittent episodes of confusion and disorientation, suggesting possible cerebral hypoperfusion or microembolic events. These new neurological symptoms prompt an urgent reevaluation of the patient's status and the potential for expedited surgical intervention. The possibility of aortic dissection or embolization necessitates close monitoring and swift clinical reasoning to prevent further deterioration and ensure patient safety.

Section 2

Following the patient's episodes of confusion and disorientation, an urgent neurological assessment was conducted, revealing a Glasgow Coma Scale score of 13, indicating mild impairment. Vital signs showed blood pressure at 165/90 mmHg, heart rate of 98 bpm, respiratory rate of 22 breaths per minute, and oxygen saturation of 94% on room air. Neurological examination indicated brisk deep tendon reflexes and slight difficulty with short-term memory recall. These findings suggested the potential for transient ischemic attacks (TIAs), likely secondary to microembolic phenomena from the mural thrombus within the aneurysm.

In response, the healthcare team expedited a transcranial Doppler ultrasound to assess cerebral blood flow, which revealed reduced velocities suggestive of compromised perfusion. Concurrently, a repeat CT angiography was performed to rule out aortic dissection and revealed no new dissections but did show a slight increase in mural thrombus burden. Based on these findings, the team initiated dual antiplatelet therapy to reduce the risk of further embolic events. Additionally, the antihypertensive regimen was intensified by adding a calcium channel blocker to better control the patient's blood pressure and reduce the risk of aneurysm expansion or rupture.

Despite these interventions, the patient experienced another episode of confusion, leading the team to reconsider the timing of surgical intervention. The multidisciplinary team, including cardiothoracic surgery and neurology, convened to discuss the risks and benefits of proceeding with surgical repair of the aneurysm versus continued medical management. The decision was made to closely monitor the patient in a high-dependency unit, ensuring rapid response capability should any further complications arise, while preparing for potential urgent surgical intervention if the patient's neurological status deteriorates further.

Section 3

New Complications:

The patient's clinical course took a concerning turn two days after the multidisciplinary team meeting. Despite the intensified medical management, the patient developed acute chest discomfort and a pronounced decrease in oxygen saturation, dropping to 88% on room air. Vital signs revealed a blood pressure of 175/95 mmHg, heart rate spiking to 120 bpm, and respiratory rate increasing to 28 breaths per minute. These alarming changes prompted immediate bedside evaluation and further diagnostic testing.

A repeat CT angiography of the chest was urgently performed, revealing a significant increase in the size of the thoracic aneurysm, now measuring 7.2 cm, with evidence of new periaortic hematoma, raising the suspicion of an impending rupture. The mural thrombus had further increased, likely exacerbating the embolic risk. Blood tests returned showing elevated D-dimer levels, suggestive of ongoing thromboembolic activity, and a mild increase in serum lactate, indicating possible tissue hypoperfusion.

This escalation in the patient's condition necessitated immediate reassessment by the cardiothoracic surgical team. The risk of catastrophic rupture had now outweighed the potential intraoperative risks, prompting the decision to proceed with emergent surgical intervention. The patient was prepared for transfer to the operating room, with an emphasis on maintaining hemodynamic stability and close neurological monitoring, given the previous episodes of confusion and disorientation. The team discussed the need for efficient coordination to optimize outcomes, highlighting the critical importance of timely surgical repair in preventing life-threatening complications.

Section 4

As the surgical team prepared the patient for the operating room, the nursing team conducted an initial preoperative assessment to ensure comprehensive documentation of the patient's status. The patient, a 65-year-old male with a history of hypertension and hyperlipidemia, appeared pale and diaphoretic, indicating increased sympathetic nervous system activity. Upon examination, breath sounds were diminished bilaterally, and the patient reported sharp, radiating pain across his chest and down his back, a typical presentation suggestive of aortic dissection or imminent rupture. Neurologically, the patient was alert but notably anxious and moderately confused, responding slowly to questions, which could indicate cerebral hypoperfusion or embolic phenomena.

In light of the new diagnostic results, including the enlarged aneurysm and periaortic hematoma, the team anticipated the potential for further complications such as distal ischemia or acute aortic syndrome. Continuous cardiac monitoring displayed frequent premature ventricular contractions, likely secondary to myocardial strain or electrolyte imbalance, necessitating vigilant cardiovascular assessment. Laboratory findings returned with hemoglobin levels slightly decreased at 11.5 g/dL, raising concerns about potential blood loss, while serum creatinine was elevated to 1.8 mg/dL, suggesting acute kidney injury from compromised renal perfusion or contrast nephropathy.

As the patient was transferred to the operating room, the anesthesiology team focused on maintaining hemodynamic stability with careful titration of intravenous fluids and vasopressors, alongside vigilant monitoring for signs of worsening perfusion or cardiovascular compromise. The surgical team was prepared for the complexity of the repair, aware that the patient's preoperative instability could affect intraoperative and postoperative outcomes. This high-stakes scenario underscored the critical importance of interdisciplinary collaboration and precise clinical reasoning to navigate the challenges posed by the patient's rapidly evolving condition, aiming to mitigate new complications and improve overall prognosis.

Section 5

As the surgery commenced, the patient's condition continued to evolve, revealing new complications. Despite the anesthesiology team's diligent efforts to stabilize hemodynamics, the patient's blood pressure remained labile, with systolic readings fluctuating between 90 and 110 mmHg. This instability heightened the risk of further compromising organ perfusion, particularly concerning for the kidneys and brain. Intraoperative transesophageal echocardiography confirmed the presence of significant aortic turbulence, indicating possible expansion of the dissection flap, which could obstruct blood flow to critical organs.

Midway through the procedure, the surgical team encountered increased difficulty controlling the bleeding around the aneurysm site, a challenge exacerbated by the patient's coagulopathy. Repeat laboratory analysis indicated a drop in hemoglobin to 9.8 g/dL and a prolonged prothrombin time, suggestive of consumption of clotting factors. These findings prompted immediate administration of blood products and clotting factor concentrates to support hemostasis. Additionally, metabolic panel results revealed a rising creatinine level now at 2.2 mg/dL, reinforcing concerns about acute kidney injury likely due to sustained hypotension and possible contrast exposure.

The cumulative impact of these developments necessitated a shift in the intraoperative strategy. The team prioritized rapid control of bleeding and stabilization of hemodynamics to prevent further deterioration. Postoperatively, the patient was anticipated to require intensive care support, with close monitoring for renal function recovery, potential neurological changes, and ongoing cardiovascular stability. This situation underscored the need for proactive, dynamic clinical reasoning and coordination among the surgical, anesthetic, and nursing teams to address these unfolding complications effectively, ensuring the best possible outcome amidst the complexity of the patient's condition.
