A & a Case Reports
|August 24, 2016
Summary
A rare complication, pseudoaneuysm, occurred after ultrasound-guided continuous adductor canal block (cACB) for knee surgery. This case highlights a potential risk despite the block
Area of Science:
- Anesthesiology
- Vascular Surgery
- Radiology
Background:
- Ultrasound-guided continuous adductor canal block (cACB) is commonly used for knee surgery.
- Major complications are rare with cACB procedures.
Observation:
- A 44-year-old patient developed quadricep impairment and a thigh hematoma on postoperative day 3.
- Laboratory tests revealed significant hemoglobin drop.
- Computed tomography confirmed a 16x16x18mm pseudoaneurysm in a superficial femoral artery branch.
Findings:
- The case presents a rare iatrogenic pseudoaneurysm following cACB.
- Successful embolization of the pseudoaneurysm was achieved via selective catheterization.
- The patient recovered and was discharged on postoperative day 12.
Implications:
- This case underscores the importance of vigilance for rare vascular complications post-cACB.
- It highlights the need for prompt diagnosis and endovascular management of pseudoaneurysms.
- Further research may explore preventative strategies or modified techniques to mitigate this risk.

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.8K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.8K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
