Summary
A rare external iliac vein aneurysm in a healthy man led to pulmonary embolism. Surgical repair with a saphenous vein graft was successful, despite temporary postoperative obstruction.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Cardiovascular Medicine
Background:
- Primary iliac venous aneurysms are rare vascular abnormalities.
- These can lead to serious complications such as pulmonary embolism, thrombosis, and rupture.
Observation:
- A 40-year-old man presented with a unilateral external iliac vein aneurysm.
- Computed tomography revealed no arteriovenous fistula, stenosis, or obstruction.
- Pulmonary embolism was confirmed via technetium-99m macroaggregated albumin scintigraphy.
Findings:
- The patient underwent aneurysmectomy and reconstruction using a saphenous vein graft.
- Anticoagulant therapy was administered to prevent further complications.
- Postoperative venography indicated external iliac vein obstruction.
Implications:
- Surgical intervention can be effective in managing iliac vein aneurysms.
- Despite postoperative findings, the patient remained asymptomatic, suggesting potential for successful outcomes.
- This case highlights the importance of timely diagnosis and management of rare vascular conditions.

01:11Work Done on a System by External Force
3.0K
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting particles. The potential energy formulation helps formulate the effect of internal forces. The net work done by an external force can be written in terms of the total change of mechanical energy, which includes both kinetic and potential energies.

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

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...

01:12Internal and External Forces

Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

01:24External and Internal Respiration
7.8K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...

01:26General External Flow Characteristics

The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...
