Summary
The popliteal artery
Area of Science:
- Anatomy
- Radiology
- Vascular Surgery
Background:
- Popliteal artery branching patterns are crucial for radiological and surgical planning.
- Understanding variations in popliteal artery anatomy is essential for precision interventions.
Purpose of the Study:
- To analyze the course and morphology of popliteal artery terminal branches using MDCT angiography.
- To determine the influence of gender on popliteal artery branching patterns.
- To identify and classify variations in popliteal artery anatomy.
Main Methods:
- Retrospective analysis of 340 lower extremity MDCT angiography scans from 170 patients (118 male, 52 female).
- Classification of popliteal artery branching types and calculation of incidence rates.
- Comparison of TPT (tibiopopliteal trunk) diameters and lengths by gender and side; calculation of dominance rates for ATA, PTA, and peroneal artery.
Main Results:
- Type IA was the most common branching pattern (89.4%); variational patterns occurred in 10.6%, with Type III being most frequent (4.1%).
- Variational patterns were twice as prevalent in females.
- Posterior tibial artery (PTA) was the most common dominant artery in both genders; new subtypes (short, standard, long) were defined for Type IA based on TPT length.
Conclusions:
- Popliteal artery branching patterns exhibit significant variation, with a higher incidence in females.
- MDCT angiography is effective for detailed anatomical assessment of the popliteal artery.
- Classification of new subtypes within the common Type IA pattern aids in more precise anatomical description.

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...

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...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

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.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
