Summary
Persistent sciatic artery aneurysm, a rare embryological anomaly, can cause painful buttock masses and L5-S1 radicular symptoms. Early recognition and surgical intervention are crucial for managing this vascular pathology.
Area of Science:
- Vascular Surgery
- Embryology
- Anatomy
Background:
- The persistent sciatic artery (PSA) is a rare congenital anomaly resulting from the failure of regression of the embryonic sciatic artery.
- It can present as a pulsatile mass, often mistaken for other conditions, and may lead to significant complications if unrecognized.
Observation:
- A 56-year-old male presented with a three-year history of a right-sided, painful buttock mass accompanied by L5-S1 radicular symptoms.
- Surgical exploration revealed a pulsatile vascular mass consistent with a persistent sciatic artery aneurysm.
Findings:
- The surgical findings confirmed the presence of a persistent sciatic artery aneurysm, highlighting its potential to cause symptomatic buttock masses.
- This case underscores the importance of considering rare vascular anomalies in the differential diagnosis of buttock pain and masses.
Implications:
- Accurate diagnosis and timely surgical management of persistent sciatic artery aneurysms are essential to prevent serious vascular complications.
- Plastic surgeons and other clinicians should be aware of this rare embryological anomaly for appropriate patient evaluation and treatment planning.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
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...
01:21Peripheral 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...
01:20Arteries 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,...
01:30Aneurysm I: Introduction
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...
01:25Abdominal 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.

01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
