de-identified ct venography systems review

what the contrast ct actually adds

a second-opinion style map of the abdominal/pelvic CT venography: pelvic veins, May-Thurner question, varicocele/fertility, prostate, renal vein, abdomen, and summer intervention gates.

the short read

The scan is most valuable as a systems map. It does not produce a single “do this procedure” answer. It shows anatomy that belongs in the summer intervention plan, especially the pelvic venous and varicocele track.

validated

what is solid

Left varicocele is real on ultrasound. CT reports bilateral varicocele/hydrocele signs, mild left common iliac vein compression, and no left renal vein compression. Prostate is described as non-enlarged and homogeneous.

uncertain

what is unresolved

The clinical meaning of the iliac compression is not settled. It needs symptoms, exam, duplex/venous review, and an independent vascular-andrology opinion. The current DFI status before any operation is unknown.

boundary

what not to do

Do not convert “mild compression on CT” into a stent plan. Do not convert “varicocele exists” into surgery without naming the indication: fertility, pain, testicular function, or recurrence prevention.

bottom line: this CT supports a conservative evidence packet for summer consults. The best next move is fresh semen analysis + DFI, symptom inventory, and independent second opinion before invasive pelvic venous diagnostics or varicocele procedure.

imaging orientation

The images below are de-identified preview contact sheets. They are not a radiology re-read. They show the phase structure and why this scan is useful for pelvic venous reasoning.

CT phase comparison: non-contrast, arterial, venous inspiratory, venous expiratory
central phase comparison: non-contrast, arterial, venous inspiratory, venous expiratory.
Arterial phase CT axial overview slices

systems extraction

The scan touches multiple repo systems. The value is not only one vessel or one operation.

systemwhat the CT contributesdecision relevance
pelvic venous Mild left common iliac vein compression by the right common iliac artery at L4-L5. Iliac tunnel reported as 8 mm on inspiration and 6 mm on expiration. Opens May-Thurner anatomy question; does not establish stent indication.
renal vein / nutcracker Left renal vein is described as typical between aorta and SMA, with no compression signs. Argues against left renal vein compression as the main varicocele driver in this report.
varicocele / hydrocele CT reports bilateral varicocele/hydrocele signs; pampiniform plexus reported 5 mm right and 4 mm left. Cross-checks ultrasound. Right side is discordant because ultrasound did not make diagnosis-forming right varicocele call.
fertility The CT adds anatomy; the semen series adds function. Counts are strong, motility generally adequate, BFC morphology repeatedly low, DFI mixed across labs. Pre-op gate should be current semen + DFI, not anatomy alone.
prostate / urinary Prostate not enlarged, homogeneous structure. Paraprostatic venous plexus reported 5-6 mm. Structural reassurance only. Does not close prostate infection/inflammation history.
abdominal organs Liver, pancreas, spleen, adrenals, kidneys described without structural changes. Gallbladder removed. Useful negative screen inside scan field; not a dedicated organ protocol.
lymph / bone No enlarged abdominal/retroperitoneal/pelvic lymph nodes. No destructive/pathologic bone-density lesions at scanned level. Gross screen reassurance, limited by report/protocol.

may-thurner: anatomy question, not stent answer

The correct label right now is left common iliac vein compression / May-Thurner anatomy question. Syndrome and intervention require symptoms and hemodynamic significance.

supports anatomy
  • left common iliac vein compression at L4-L5
  • smaller venous tunnel on expiration than inspiration
  • pelvic venous plexus context exists
does not support automatic stent
  • wording is mild
  • no DVT reported
  • no collateral-severity language reported
  • no pressure-gradient or IVUS significance documented
  • symptom inventory is still missing
stent gate: stent discussion requires meaningful symptoms, objective obstruction, alternatives review, antithrombotic plan, complication plan, and independent second opinion. Diagnostic venography/IVUS should not silently become a same-session implant.

varicocele + fertility logic

The varicocele question has two layers: scrotal disease and upstream pelvic venous anatomy. They should be reviewed together, but the procedure indication must be explicit.

left side

Ultrasound confirms left I86.1 varicocele, orthostatic, Sarteschi 3/5. This is the strongest varicocele finding.

right side

CT reports bilateral signs, but ultrasound did not make a diagnosis-forming right varicocele call. Treat as discordant, not settled bilateral disease.

fertility

No children yet keeps fertility active. Prior conception argues against a gross absolute male-factor block. Miscarriage at 12 weeks is not automatically a varicocele signal.

possible indicationwhat would make it strongerwhat is missing now
fertility optimizationcurrent abnormal semen/DFI trend, high DFI recurrence, unexplained infertility context, clinically significant varicocelefresh same-method semen + DFI before surgery
painclear scrotal pain phenotype, side-specific, posture/standing relation, exam correlationstructured symptom inventory
testicular functionvolume asymmetry/atrophy trend, endocrine or semen consequencevolume trend and andrology interpretation
recurrence preventionclinically meaningful upstream pelvic obstructionindependent venous hemodynamic review

semen series: why one snapshot is misleading

There is a real longitudinal series. The pattern is not “low sperm production.” The more relevant pattern is mixed DNA integrity, low morphology by one lab style, and recurring agglutination/aggregation.

interpretation: the DFI swing may be real improvement, lab-method difference, abstinence/context, heat/illness/inflammation, or sampling variability. Current DFI is unknown because the 2026 test did not include it.

summer intervention gate

This is the action path that prevents the easiest clinic funnel from becoming the plan.

before consult
  • complete symptom inventory: leg swelling, heaviness, claudication, skin changes, pelvic pain, scrotal pain, DVT history, training limits
  • repeat semen analysis + DFI in a stable window
  • bring CT report, DICOM manifest, scrotal ultrasound, semen series, and prior doctor call as context
at consult
  • ask whether this is May-Thurner syndrome, anatomy, or neither
  • ask what result would change management
  • pre-commit: no diagnostic-to-stent same-session conversion
  • ask whether varicocele target is fertility, pain, volume/function, or recurrence prevention
