Anastomoses01:19

Anastomoses

2.0K
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They...

Venous Thrombosis I: Introduction

131
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Peripheral Artery Disease I: Introduction

161
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Aneurysm III: Interprofessional Care

121
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...

Area of Science:

  • Interventional Radiology
  • Vascular Anatomy
  • Urology

Background:

  • Benign prostatic hyperplasia (BPH) causes lower urinary tract symptoms.
  • Prostate artery embolization (PAE) is an effective minimally invasive treatment for BPH.
  • Variations in prostatic arterial anatomy can complicate PAE procedures.

Purpose of the Study:

  • To review variant prostatic artery origins.
  • To describe collateral circulation relevant to PAE.
  • To provide anatomical guidance for interventional radiologists performing PAE.

Main Methods:

  • Literature review of prostatic arterial anatomy.
  • Analysis of anatomical variations and collateral pathways.
  • Discussion of implications for PAE technique.

Main Results:

  • Prostatic arterial anatomy exhibits significant variability.
  • Common and uncommon origins of prostatic arteries are identified.
  • Key collateral pathways that may supply the prostate are detailed.

Conclusions:

  • Awareness of prostatic arterial variants is essential for successful PAE.
  • Detailed anatomical knowledge can mitigate technical challenges in PAE.
  • This review serves as a primer for interventional radiologists performing PAE.
