Summary
A rare popliteal pseudoaneurysm occurred after total knee replacement surgery. Prompt diagnosis and surgical repair with a synthetic graft led to successful limb salvage and improved mobility.
Area of Science:
- Vascular Surgery
- Orthopedic Surgery
- Medical Case Reports
Background:
- Total knee replacement (TKR) is a common orthopedic procedure.
- Complications, though rare, can occur post-TKR, impacting vascular structures.
- Popliteal pseudoaneurysms are an uncommon but serious complication.
Purpose of the Study:
- To report a case of popliteal pseudoaneurysm following TKR.
- To highlight the diagnostic challenges and management of this rare complication.
- To emphasize the importance of timely vascular assessment in post-TKR patients with limb symptoms.
Main Methods:
- A 70-year-old female patient underwent TKR for osteoarthritis.
- Initial symptoms of calf edema and pain were misdiagnosed as deep vein thrombosis.
- Advanced imaging (sonography, angiography) confirmed a large popliteal artery pseudoaneurysm.
Main Results:
- The patient presented with worsening calf symptoms and diminished distal pulses.
- Sonography and angiography revealed a significant popliteal artery pseudoaneurysm.
- Surgical intervention involved resection of the affected artery segment and reconstruction with a PTFE graft.
Conclusions:
- Popliteal pseudoaneurysm is a critical complication that can arise after TKR.
- Early recognition and appropriate vascular imaging are crucial for accurate diagnosis.
- Surgical management with vascular reconstruction can achieve successful outcomes and limb salvage.

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:20Arteries 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 artery,...
01:27Peripheral 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...
01:26Aneurysm 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...
01:21Peripheral 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...
01:21Sites for measuring blood pressure
Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.
