02History/hx58

Presentation pattern

›Core symptom complex

›Sudden-onset unilateral lower abdominal or pelvic pain

›Often described as pop or acute tearing sensation

›Acute onset distinguishes from chronic pelvic pain

›Pain severity and trajectory

›Ranges from mild discomfort to severe incapacitating pain

›Persistent or worsening despite analgesia raises surgical concern

›Associated symptoms

›Nausea and vomiting

›Vaginal bleeding

›Lightheadedness or presyncope if significant hemorrhage

Timing and triggers

›Cycle phase context

›Mid-cycle occurrence suggests follicular cyst

›Mittelschmerz distinction

›Luteal phase occurrence suggests corpus luteum cyst

›Corpus luteum more vascular, higher hemorrhage risk

›Most common cyst type in ruptured series

›Trigger activities

›Sexual intercourse

›Exercise or straining

›No consistent trigger identified in studies

Menstrual and reproductive history

›Key reproductive data

10Background/b53

Epidemiology

›Incidence and prevalence

›Common gynecological emergency

›Ruptured ovarian cysts represent a frequent ED presentation

›Most common type: corpus luteum cyst rupture

›Peak incidence in reproductive-age women 15-45 years

›Surgical vs conservative outcomes

›Approximately 80-85% of cases managed conservatively

›Surgery required in 15-20% of cases

›Primary indications for surgery: hemodynamic compromise or large hemoperitoneum

›Right-side predominance

›Majority of ruptures occur on the right ovary

›Postulated mechanisms: proximity to appendix, differences in venous drainage

›Anticoagulation prevalence

›Anticoagulated patients dramatically over-represented in surgical cases

›Life-threatening hemoperitoneum risk markedly elevated on anticoagulants

Pathophysiology

›Cyst formation and rupture mechanisms

›Functional cyst development

›Follicular cysts form when Graafian follicle fails to rupture or resorb

›Corpus luteum cysts develop from vascular corpus luteum after ovulation

›Corpus luteum is a highly vascular structure supplied by luteal arteries

›Hemorrhage mechanism

›Spontaneous or triggered rupture of cyst wall

›Blood from ruptured corpus luteum vessels fills peritoneal cavity

›Volume of hemorrhage depends on vessel caliber and coagulation status

›Peritoneal response

›Blood in peritoneum causes chemical peritonitis
